My macOS Catalina / Proxmox setup

I thought it might be helpful for people following my guide for installing macOS Catalina on Proxmox if I described my setup and how I’m using macOS.

Proxmox hardware specs

  • Motherboard: Asrock EP2C602
  • RAM: 64GB
  • CPU: 2 x Intel E5-2670 for a total of 16 cores / 32 threads

My Proxmox machine is my desktop computer, so I pass most of this hardware straight through to the macOS Catalina VM that I use as my daily-driver machine. I pass through both USB 2 controllers, the USB 3 controller, the NVMe SSD, and one of the gigabit network ports, plus the R9 280X graphics card.

Attached to the USB controllers I pass through to macOS are a Bluetooth adapter, keyboard, Logitech trackball dongle, and a DragonFly Black USB DAC for audio (the motherboard has no audio onboard).

Once macOS boots, this leaves no USB ports dedicated to the host, so no keyboard for the host! I normally manage my Proxmox host from a guest, or if all of my guests are down I use SSH from a laptop or smartphone instead (JuiceSSH on Android works nicely for running qm start 100 to boot up my macOS VM if I accidentally shut it down).

On High Sierra, I used to use the GTX 750 Ti, then later the GTX 1060, to drive two displays (one of them 4k@60Hz over DisplayPort) which both worked flawlessly. However NVIDIA drivers are not available for Catalina, so now I’m back with my old R9 280X, which has some built-in support.

R9 280X being unnecessarily nosy

This Radeon card is not stable for the guest; I get flashing video corruption on parts of the screen intermittently, and it’s not stable for the host, triggering DMAR warnings that suggest that it tries to read memory it doesn’t own, and causing random host lockups the second time that a VM that uses it is booted. I’m looking forward to those new NVIDIA drivers so that I can stop using this card!

Take note that if your video card does not support booting using UEFI, you’ll be in a world of pain due to VGA bus arbitration conflicts with the host. Although it is possible to patch the VBIOS of some old video cards to support UEFI, you will save a lot of blood, sweat and tears by just buying a newer video card!

On this motherboard is a third SATA controller, a Marvell SE9230, but enabling this in the ASRock UEFI setup causes it to throw a ton of DMAR errors and kill the host, so avoid using it.

What I use it for

I’m using my Catalina VM for developing software (IntelliJ / XCode), watching videos (YouTube / mpv), playing music, editing photos with Photoshop and Lightroom, editing video with DaVinci Resolve, buying apps on the App Store, syncing data with iCloud, and more. That all works trouble-free. I don’t use any of the Apple apps that are known to be troublesome on Hackintosh (iMessage etc), so I’m not sure if those are working or not.

VM configuration

Here’s my VM’s Proxmox configuration, with discussion to follow:

args: -device isa-applesmc,osk="..." -smbios type=2 -cpu Penryn,kvm=on,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+aes,+xsave,+xsaveopt,check -smp 32,sockets=2,cores=8,threads=2 -machine type=q35,kernel_irqchip=on

vga: none
hookscript: local:snippets/
My CPU masquerades as a Penryn (which appears to be a requirement for macOS to boot) but Catalina also requires CPU features that were first introduced in the subsequent Nehalem CPU generation, so those need to be added (ssse3, sse4.2, and popcnt). On top of that I’m passing through some more features that my CPU supports that can speed up macOS (AVX, AES-NI, etc) . You can use cat /proc/cpuinfo on Proxmox to check what features your CPU supports.
macOS refuses to boot on my machine if I pass certain numbers of cores through to it, so I ended up having to pass all 32 threads through to the VM instead of the 24 I intended. Proxmox’s configuration format doesn’t natively support setting a thread count, so I had to add my topology manually here by adding “-smp 32,sockets=2,cores=8,threads=2”.
It appears that new defaults in the q35 machine type in Proxmox 6 now requires the addition of “-machine type=q35,kernel_irqchip=on” for half of my passthrough devices to work correctly.
I’m passing through 6 PCIe devices, which Proxmox doesn’t support natively (it normally maxes out at 4), so I had to patch Proxmox to add support. From first to last I have my graphics card, two USB 2 controllers, my NVMe storage, a USB 3 controller, and one gigabit network card.
40 gigabytes, baby!
I usually have this emulated network card disabled in Catalina’s network settings, and use my passthrough Intel 82574L instead.
Although Catalina has a driver for the Intel 82574L, the driver doesn’t match the exact PCI ID of the card I have, so the driver doesn’t load and the card remains inactive. Luckily you can edit the driver to fix this. First check the PCI ID of the network card in Proxmox:
# lspci -nn | grep 82574L

0b:00.0 Ethernet controller [0200]: Intel Corporation 82574L Gigabit Network Connection [8086:10d3]

The PCI ID here is 8086:10d3.

On macOS, remount the root partition read-write:

sudo mount -uw /

Now edit /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/Intel82574L.kext/Contents/Info.plist. Find the section which defines IOPCIPrimaryMatch and IOPCISecondaryMatch:

<string>0x104b8086 0x10f68086</string>
<string>0x00008086 0x00000000</string>

Those define the hardware that the driver will be loaded for. Remove those lines and replace them with a new “IOPCIMatch” section that has your PCI ID in it:


Note that in this format, the last part of the PCI ID (10d3) needs to come first, followed by the first part (8086). After rebooting macOS, the network driver will now consider your card to be compatible, and will load for it. Note that changing your network card can break software that relies on your MAC address staying the same for license checking / DRM.

I need to set this to “none”, since otherwise the crappy emulated video card would become the primary video adapter, and I only want my passthrough card to be active.
This is a new feature in Proxmox 5.4 that allows a script to be run at various points in the VM lifecycle.
In recent kernel versions, some devices like my USB controllers are grabbed by the host kernel very early during boot, before vfio can claim them. This means that I need to manually release those devices in order to start the VM. I created /var/lib/vz/snippets/ with this content (and marked it executable with chmod +x): 
#!/usr/bin/env bash

if [ "$2" == "pre-start" ]
# First release devices from their current driver (by their PCI bus IDs)
echo 0000:00:1d.0 > /sys/bus/pci/devices/0000:00:1d.0/driver/unbind
echo 0000:00:1a.0 > /sys/bus/pci/devices/0000:00:1a.0/driver/unbind
echo 0000:81:00.0 > /sys/bus/pci/devices/0000:81:00.0/driver/unbind
echo 0000:82:00.0 > /sys/bus/pci/devices/0000:82:00.0/driver/unbind
echo 0000:0a:00.0 > /sys/bus/pci/devices/0000:0a:00.0/driver/unbind

# Then attach them by ID to VFIO
echo 8086 1d2d > /sys/bus/pci/drivers/vfio-pci/new_id
echo 8086 1d26 > /sys/bus/pci/drivers/vfio-pci/new_id
echo 1b73 1100 > /sys/bus/pci/drivers/vfio-pci/new_id
echo 144d a802 > /sys/bus/pci/drivers/vfio-pci/new_id
echo 8086 10d3 > /sys/bus/pci/drivers/vfio-pci/new_id

Guest file storage

The macOS VM’s primary storage is the passthrough Samsung 950 Pro 512GB NVMe SSD, which can be installed onto and used in Catalina with no issues. TRIM is supported and enabled automatically.

For secondary storage, my Proxmox host exports a number of directories over the AFP network protocol using netatalk. 

Proxmox 5

Debian Stretch’s version of the netatalk package is seriously out of date (and I’ve had file corruption issues with old versions), so I installed netatalk onto Proxmox from source instead following these directions:

My configure command ended up being:

./configure --with-init-style=debian-systemd --without-libevent --without-tdb --with-cracklib --enable-krbV-uam --with-pam-confdir=/etc/pam.d --with-dbus-daemon=/usr/bin/dbus-daemon --with-dbus-sysconf-dir=/etc/dbus-1/system.d --with-tracker-pkgconfig-version=1.0

Netatalk is configured in /usr/local/etc/afp.conf like so:

; Netatalk 3.x configuration file


path = /tank/downloads
rwlist = nick ; List of usernames with rw permissions on this share

path = /tank/isos
rwlist = nick

When connecting to the fileshare from macOS, you connect with a URL like “afp://proxmox”, then specify the name and password of the unix user you’re authenticating as (here, “nick”), and that user’s account will be used for all file permissions checks.

Proxmox 6

Proxmox 6’s prebuilt version of Netatalk is good now, so I backed up my afp.conf, removed my old version that was installed from source (with “make uninstall”, note that this erases afp.conf!), and apt-installed the netatalk package instead. The configuration is now found at /etc/netatalk/afp.conf.

Proxmox configuration

Passthrough of PCIe devices requires a bit of configuration on Proxmox’s side, much of which is described in their manual. Here’s what I ended up with:


GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on rootdelay=10"

Note that Proxmox 6 can now be booted using systemd-boot rather than GRUB (to support ZFS root volumes on UEFI systems). If you’re using systemd-boot:

/etc/kernel/cmdline (Proxmox 6 when using systemd-boot)

root=ZFS=rpool/ROOT/pve-1 boot=zfs intel_iommu=on rootdelay=10

# Note that adding disable_vga here will probably prevent guests from booting in SeaBIOS mode

After editing those files you typically need to run update-grub (or pve-efiboot-tool refresh if you are using systemd-boot on Proxmox 6), update-initramfs -k all -u, then reboot Proxmox.

Host configuration

In the UEFI settings of my host system I had to set my onboard video card as my primary video adapter. Otherwise, the VBIOS of my discrete video cards would get molested by the host during boot, rendering them unusable for guests (this is especially a problem if your host boots in BIOS compatibility mode instead of UEFI mode).

One way to avoid needing to change this setting (e.g. if you only have one video card in your system!) is to dump the unmolested VBIOS of the card while it is attached to the host as a secondary card, then provide that copy of the VBIOS as a file to Proxmox using a “romfile” option like so:

hostpci0: 01:00,x-vga=on,romfile=/root/my-vbios.bin

Or if you don’t have a spare discrete GPU of your own to achieve this, you can find somebody else who has done this online. However, I have never tried this approach myself.

Guest configuration

In Catalina, I have system sleep turned off in the power saving options (because I had too many instances where it went to sleep and never woke up again).

I used Clover Configurator to set my SMBIOS to iMac 14,2 before I tried passing through any hardware.

Launching the VM

I found that when I assign obscene amounts of RAM to the VM, it takes a long time for Proxmox to allocate the memory for it, causing a timeout during VM launch:

start failed: command '/usr/bin/kvm -id 100 ...'' failed: got timeout

You can instead avoid Proxmox’s timeout system entirely by running the VM like:

qm showcmd 100 | bash

Another RAM problem comes if my host has done a ton of disk IO. This causes ZFS’s ARC (disk cache) to grow in size, and it seems like the ARC is not automatically released when that memory is needed to start a VM (maybe this is an interaction with the hugepages feature). So the VM will complain that it’s out of memory on launch even though there is plenty of memory marked as “cache” available.

You can clear this read-cache and make the RAM available again by running:

echo 3 > /proc/sys/vm/drop_caches



My VM was configured with a passthrough video card, and the config file also had “vga: std” in it. Normally if there is a passthrough card enabled, Proxmox disables the emulated VGA adapter, so this was equivalent to “vga: none”. However after upgrading pve-manager to 5.3-12, I found that the emulated vga adapter was re-enabled, so Clover ended up displaying on the emulated console, and both of my hardware monitors became “secondary” monitors in macOS. To fix this I needed to explicitly set “vga: none” in the VM configuration.


Added “hookscript” to take advantage of new Proxmox 5.4 features


Did an in-place upgrade to Proxmox 6 today!

Proxmox 6 now includes an up-to-date version of the netatalk package, so I use the prebuilt version instead of building it from source. Don’t forget to install my new patched pve-edk2-firmware package.

I had to add “-machine type=q35,kernel_irqchip=on” to my “args” to fix my PCIe passthrough devices (see comment in the args section above).

100 thoughts on “My macOS Catalina / Proxmox setup”

  1. Until proxmox builds new .deb files with edited perls for exposing fake ssd virtual disks to the osx vm (needed for restoring a time machine backup to a disk) here is how I done it.
    important part is rotation_rate and has to be added to args: in vmid.conf

    -drive file=”/dev/path-to-volumegroup/logicalvolume,if=none”,id=drive-ide0,cache=unsafe,format=raw,aio=threads,detect-zeroes=on -device ‘ide-hd,bus=ide.0,unit=0,drive=drive-ide0,id=ide0,rotation_rate=1’

    1. Not sure if it’s a new update but I’m seeing the option for “SSD emulation” (check advanced for the drive). MacOS then shows it as Solid State.

  2. Hi,
    I don’t understand why my gpu dont show any signals …

    What did i miss ?

    1. What’s that “00:01.0” device that’s also in the same group as your card?

      Does your card have a UEFI BIOS? I think that’s required since the guest boots in UEFI mode. Sometimes there are patched BIOS images available on the internet that you can supply with the “romfile” argument to “hostpci0” to use.

      You can try creating a new VM in SeaBIOS mode and see if the card turns on there.

      1. Hi,

        “00:01.0”, just one part form the result of the command i don’t know

        to test efi on gpu :
        run : cat rom > /tmp/image.rom
        get : cat: rom: Input/output error

        I have found this
        And use ./rom-fixer ../Gigabyte.GTX650.2048.131211.rom

        When start win10 with SeaBIOS :
        kvm: -device vfio-pci,host=01:00.0,id=hostpci0.0,bus=ich9-pcie-port-1,addr=0x0.0,x-vga=on,multifunction=on: vfio error: 0000:01:00.0: failed getting region info for VGA region index 8: Invalid argument
        device does not support requested feature x-vga

        This is because proxmox still using it ? if yes, why ?

        1. Because you have “disable_vga=1” in your vfio-pci options, your passthrough card will no longer be available for use in SeaBIOS systems (these require VGA support).

          You can remove this setting to make the card compatible with both BIOS and UEFI guests, but you will have a greater chance of booting a guest locking up the host due to VGA arbitration conflicts. It’s better to install windows using UEFI.

          Run “lspci -s 00:01.0” to see what that device is, I guess it’s a PCIe root port or something. You may need to explicitly pass it through to the guest by adding another hostpci line, since everything in the same iommu group has to be passed through at once. edit: apparently it doesn’t need to be explicitly passed through:

          1. lspci -s 00:01.0
            00:01.0 PCI bridge: Intel Corporation Skylake PCIe Controller (x16) (rev 07)

            I removed “disable_vga=1” still not start.
            I will try to install windows using UEFI (so put “disable_vga=1” in vfio-pci options ?).

            I don’t know what I’m doing exactly so it’s hard to follow you 🙁

            This is too hard for me, I don’t see the problem and understand this. I will stay with the bad graphics on the macOS Mojave VM, and control it under the web gui of proxmox 🙁

            Thanks a lot for your time and help.

          2. What error do you get when booting the Windows installer with UEFI? Yeah, you want “disable_vga=1” if all your guests will be UEFI.

            You can have Proxmox use your patched VBIOS like so:

            hostpci0: 01:00,x-vga=on,romfile=/tmp/Gigabyte.GTX650.2048.131211.rom

          3. Hi,

            So installed Win10 with UEFI, use “disable_vga=1”, in VM conf : “hostpci0: 01:00,x-vga=on,romfile=Gigabyte.GTX650.2048.131211.rom” (Copied the rom in /usr/share/kvm/)
            and finally run “update-grub”, “update-initramfs -k all -u”.

            Start with no errors in the logs (TASK OK).
            But no output signals.
            Somthing is strange here ( we can see if our card is valid for the EFI boot right ?

            When I run
            # cd /sys/bus/pci/devices/0000:01:00.0/
            # echo 1 > rom
            # cat rom > /tmp/image.rom
            I got >>> cat: rom: Input/output error
            # echo 0 > rom

            (I have enable the internal graphics to see the boot of proxmox)

            My card should be the second card and not be used by proxmox right ?
            (I will try to move the card in an other PCI slot this evening)

          4. So, I change the card to an other PCI slot :
            lspci -n -s 02:00
            02:00.0 0300: 10de:0fc6 (rev a1)
            02:00.1 0403: 10de:0e1b (rev a1)

            and change vm config :
            hostpci0: 02:00,pcie=1,x-vga=on,romfile=Gigabyte.GTX650.2048.131211.rom
            > No signal output either

    1. Yes I have test with 2 HDMI Câbles and monitors.
      In your case when you make a gpu passthrough you can see the console output of your VM in the web gui of proxmox ?

      1. Can you double check that vfio-pci is getting the card correctly? `lspci -nn -k | grep -i -A 2 nvidia` should say “Kernel driver in use: vfio-pci”.

        1. lspci -nn -k | grep -i -A 2 nvidia
          02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK107 [GeForce GTX 650] [10de:0fc6] (rev a1)

          Kernel driver in use: vfio-pci

          1. That looks good, but it shows that there are Nvidia drivers available that you aren’t blacklisting, and these could be wrecking your GPU during host boot. Update your /etc/modprobe.d/blacklist.conf to be:

            blacklist nvidia
            blacklist nvidiafb
            blacklist nouveau

            Then `update-initramfs -k all -u` and reboot the host.

            You may also need to blacklist the driver for the video card’s audio controller (one of snd_hda_codec_hdmi, snd_hda_intel, snd_hda_codec, snd_hda_core probably, look at the full output of “lspci -nn -k” to check).

  3. Content of “/etc/modprobe.d/blacklist.conf” :
    blacklist nouveau
    blacklist nvidia
    blacklist nvidiafb
    blacklist snd_hda_codec_hdmi
    blacklist snd_hda_intel
    blacklist snd_hda_codec
    blacklist snd_hda_core
    blacklist radeon
    blacklist amdgpu

    I’m not home so as you said “adding passthrough video disables the console view entirely”…
    I will check it this evening thanks.

      1. Oh I forgot one more thing, make sure that your host UEFI/BIOS is set to make your onboard video primary instead of the card you want to pass through.

        If that still doesn’t work then I’d expect it to be due to the card’s BIOS not supporting UEFI properly.

        1. Hi, yes I used the onboard video for proxmox boot. I also tested with the gpu card to boot (Seen proxmox boot) and start the VM (Immediate black screen), So I imagine, proxmox dedicate the card to the VM but there are no signals from it.
          As you said, maybe my gpu can not use UEFI.

  4. Great tutorial(s)!

    How much is your systems power consumption?

    My Dell T20 setup (Exxon with 16 GB Ram) consumes < 45W with 4 x SSDs, 4 x 2.5" 1TB HDDs, 1 USB 3.0 PCI-E Card, 1 Nvidia GT710 (works great with passthrough) and 1 PERC H310.
    But I need a better performance and more processor cores, so I am looking for a good replacement with low power consumption at all.

    1. Good idea, I’ll do some current measurements with a clamp meter, let’s see…

      When my host is completely idle (no VMs), it sits at 180W. Adding an idle macOS VM brings that up to 220W.

      Running a Prime95 stress test on the host brings it to 500W peak.

      I’ve got 9×3.5″ hard drives, 2 SSDs, and 8 sticks of DDR3, so they probably account for a lot of the idle power consumption. It certainly keeps my desk toasty warm at all times!

      I suspect if you want something power efficient then you should stay away from multiple-socket systems like mine.

  5. Hi, it’s me again 😉
    You said you are using a “DragonFly Black USB DAC for audio”. In the future, I want a KVM to switch my mouse and keyboard and HDMI output between Windows VM and MacOS VM.
    So, I pass through the USB keyboard and mouse (and with your help a GPU thanks a lot) and all is working great. But I need some sound, so I pass through my USB headset (Logitech G35) and the sound output is very strange, it’s likes someone clicks pause and play very fast (crackles) did you know how to solve this?. (Google not very helpful, or not, find something useful).
    See something about “args: -device AC97, addr=0x18” but it’s not helping (Maybe it’s for “jack” sound card of the mother board but it’s not my goal). If you think it’s just the driver is missing (because I cannot find a MacOS driver for the G35) I will make me sad :(.

    Thanks again for all your help

    1. I’m passing through an entire USB controller using PCIe passthrough, I think you’ll end up with timing issues if you use the emulated soundcard like you’re showing instead.

      USB audio devices should work without a specialised driver, there’s a USB audio standard that they conform to (similar to USB Mass Storage for USB drives).

      Another option, if your video card driver is cooperative and your monitor supports it, is to send your audio out over HDMI and have your monitor decode it to a headphone jack on the monitor. I had some trouble doing that in the past but it helped out to add Lilu and Whatevergreen to my Clover kexts/other directory (and edit config.plist to enable kext injection):

        1. You might get enough performance by just passing through your physical drives as virtual disks instead:

          Instead of “virtio2” suggested there, you’ll want to use SATA instead like “sata1”.

          You can indeed use PCIe passthrough to pass through a SATA controller like the one you linked, but I haven’t tried that particular model out myself.

          1. Ok (I need a RAID 1), but I will make a pass through real drives like you, thanks for the advice and your time !

  6. After hours of tinkering to get GPU pass through working on Mojave/Proxmox 5.3 (new to the VE). Finally got vfio-pci to show as the kernel driver. Sadly Mojave won’t load my R7-265 driver. This is what I get in info pci in the monitor with the guest running. So guessing something is awry 🙂 Thx for the guide though, might try High Sierra since it has proper GTX – 1xxx support.

    # info pci
    Bus 0, device 0, function 0:
    Host bridge: PCI device 8086:29c0
    id “”
    Bus 0, device 1, function 0:
    VGA controller: PCI device 1234:1111
    BAR0: 32 bit prefetchable memory at 0x90000000 [0x97ffffff].
    BAR2: 32 bit memory at 0x99207000 [0x99207fff].
    BAR6: 32 bit memory at 0xffffffffffffffff [0x0000fffe].
    id “vga”

    I know there’s no guarantee as it’s a Hackintosh lol. Hopefully Nvidia/Apple will at some point release drivers for Mojave though I doubt it’ll be any time soon.

  7. Hi something is strange with my nvme, in /dev there is no /dev/nvme*. When i make a PCI through with it, no start of the VM : […] vfio error failed to add PCI capability […]. I change the GRUB_CMDLINE_LINUX_DEFAULT=”quiet intel_iommu=on rootdelay=10″ like you. did you have some ideas ? thanks

        1. If you’re using an NVMe slot on your motherboard, check your motherboard manual to see if it needs to be enabled in UEFI settings, or if it shares PCIe lanes with one of your other cards (so that card needs to be moved to a different slot).

          1. Hi, I finally use the “Physical disk to kvm” method (sata0: /dev/disk/by-id/nvme-INTEL[blabla…] and sata1: /dev/disk/by-id/ata-KINGSTON_[blabla…]). But in the VM the disk is a “type : rotation” so I search in the proxmox doc and tow option seem to be perfect the “ssd=1” and “discard=on”. The thing is when i added theses parameters, the disk disappeared in the hardware tab and obviously, no boot. How do you define a SSD (best way, beacause it’s work by default but not futur proof for my SSD I think) ?

          2. Maybe your syntax was wrong? Here’s what one of my disks looks like that uses those flags:

            scsi0: vms-ssd:vm-141-disk-0,cache=unsafe,discard=on,size=128G,ssd=1

            I think that the “discard” option is probably not meaningful when passing through a disk like that, so I’d leave it off.

            PCIe passthrough will give you much better performance, and TRIM support. When you tried your NVMe passthrough, did you remember to update your vfio config to add the PCIe ID of your NVMe drive?

          3. Yes,
            I Search the ID with : lspci
            03:00.0 Non-Volatile memory controller: Intel Corporation Device f1a6 (rev 03)
            and with : lspci -n -s 03:00
            03:00.0 0108: 8086:f1a6 (rev 03)
            to add it in the config file here :
            (In your guide is : /etc/modprobe.d/vfio-pci.conf not in
            options vfio-pci ids=10de:13c2,10de:0fbb,10de:128b,10de:0e0f,8086:f1a6,1b73:1100 disable_vga=1
            And finally use :
            update-initramfs -k all -u
            And reboot
            In the VM config file :
            hostpci0: 03:00.0,pcie=1
            (Yes this is a M.2 slot in the motherboard)
            For classic SATA SSD, mabye i think, adding ssd=1 can only work with virtual disk (like you vm-141-disk-0 no) ?

          4. Thanks for your help once again ;)I will keep the working configuration, the performances are good enough for me.
            But for the ssd=1 it’s strange…
            Anyway, maybe some update will fix it (I have a proxmox 5.2-1 on the top and maybe your patch will not work with a newer version)

          5. Hi i just (take the risk) make a dist-upgrade to PVE 5.3-6 and ssd=1 works fine TRIM enabled.
            So simple…

  8. Hi,
    Is your EVGA GeForce GTX 1060 6GB working now or you still with the AMD Radeon R9 280X ?
    I tested with KFA2 GTX 970 EXOC but the screen is not used entirely not like the GT 710 working great. So I wonder if is the hackintosh compatibility or this is the “no NVIDIA Mojave driver” problem.
    Anyway, I will probably buy an RX 560 later.

  9. Hi, a little thing you can add in your “Proxmox hardware specs” is the case because “9×3.5″ HDD and 2 SSDs” is not easy to install in most desktop cases 🙂

    1. Haha, very true! I’m lucky to have a desk that’s tall enough to fit this thing underneath it. I’ve updated the post with the details of the case now.

      1. Nice, thanks for this 😉
        What is the “global configuration” of the “30TB of spinning disks in various ZFS configurations” because with the “Lian Li EX-H35 HDD Hot Swap Module” I can imagine you use it like a NAS (only 3 of 9) and the others is some zfs pool (like a RAID 1) ?
        I am thinking to build a custom NAS with a VM and pass through the disks and create a VM with FreeNAS for example (bad performance ? I think so…).
        But for you, how did you use your 9 disks? (in the VM too, performances?).

        1. I have 3 + 4 + 4 TB of non-redundant storage (used for “Linux ISOs” and backups), then 3 x 3TB in RAIDZ1 and 3 x 4TB as another RAIDZ1.

          FreeNAS is what I upgraded from. But I can’t see a reason to use it anymore now that ZoL (ZFS-on-Linux) is so mature on Proxmox.

          I had been some running VMs from the RAIDZ1 arrays, but the performance of spinning disks in this config is just way too slow. I now try to run all of my common VMs from my 1TB SATA SSD using SCSI emulation (my macOS VM has its own 512GB NVMe SSD using PCIe passthrough).

          1. “I had been some running VMs from the RAIDZ1 arrays” Is it a virtual disk file like VMID.row in the storage mount as RAIDZ1 (Classic use, file on disk is the virtual disk) or the RAIDZ1 (entire zpool) is a complete virtual disk and the VM see it like a normal disk ?
            In fact, this is what I try to do, create a zpool (RAIDZ1 for example) and use use the entire zpool like a virtual disk for the VM.
            With that, we can encrypt, change disk and it will be “transparent” like a normal disk for the VM.

          2. The disk images are ZFS “zvols”. This gives you all the management abilities of ZFS on the host and the VMs just see a regular disk.

          3. I’m thinking about this : passthrough the NVMe in the VM. How did you migrate, restore, or if you change it for a new one like for the samsung 960 pro 1To.
            Is The only way like you explain here ?
            With something like : dd if=/path/to/the/disk/image/backup of=/dev/disk/id
            Or there is something now in proxmox to do that ? So what is your plan if something happened on your NVMe (if failed) ?
            (I searched for restore vm disk in assigned disk, but nothing interesting)

          4. Yes, I just used DD as described there. If the source disk image is smaller than the SSD you’re copying it to, it becomes pretty straightforward and you just need to grow the partition to fill the disk in Disk Utility after you’ve booted up your new copy from the SSD.

            My VM has backup software installed which sends file backups to a separate drive on the host over ssh (Duplicacy). You could also use dd from the host to make an image of the SSD as backup, before the SSD is detached from the host for the guest’s use.

  10. Really awesome guides, thank you! Would you post some picturesicture of what your machine looks like? I’d like to see how all of your components fit together, especially with 3 graphics cards.

  11. Hi, thank you for sharing your Mojave installation Guide and this setup details, I basically follow your guide and have my Proxmox machine running Mojave now. Really appreciate it!

    I do have a problem with PCI passthrough a Broadcom wifi/bluetooth card to Mojave-VM though. I am hoping you can take a look and help me.

    I have posted the details in this reddit link:

    The most simplified version of my problem is, I can PCI passthrough the GPU, one USB controller and one NVMe card to the VM already, but somehow the Broadcom card can’t be passed through. The Device ID of the Broadcom card, which is 04:00.0 does show up in the result of a “lspci -nn” command, but when I tried to start the VM for the first time after a reboot of the Proxmox computer, the start will fail, with a VFIO error message saying no 04:00.0 device. Then I run “lspci -nn” command again, the line of device 04:00.0 really disappeared.

    I have described my problem in details at the reddit link above, hope you don’t mind taking a look there. Many many thanks!

    1. I’m running proxmox/PCIe pass throught with Sapphire RX-580 nitro+ like you do. Are you facing problems with the AMD GPU reset bug?

      1. I don’t think my R9 280X (Tahiti XTL / Radeon HD 7970) suffers from the reset bug (when the wind is blowing right, I can start a guest multiple times). However macOS doesn’t seem to like my card anyway and I get some screen corruption, I wouldn’t recommend my card.

        The reset bug only applies to specific AMD GPU series. The RX-580 is Polaris architecture and I don’t think that one had a series-wide reset bug.

      1. I’ve rebooted the host and it won’t boot at all now. It reboots after “End randomseed”. I’ve updated Mojave to its latest version, but it booted after, so I doubt it’s that.

        1. Did you upgrade your host packages at the same time? You may have accidentally upgraded away from my patched OVMF package:

          Sorry, the only Proxmox trick I know for getting macOS to boot using weird numbers of cores is to manually set threads=2 using a custom -smp commmand in “args” (mentioned in this post). There are numbers of cores that won’t boot for me either.

          1. The args line disapeared somehow. That’s why it wasn’t booting. I’m not sure yet, but the VM seems to have stopped freezing when I stopped using Synergy.

  12. It just crashed again. Nothing in dmesg. The image just freezes and VM must be reset. It also does it with a Windows VM. Maybe my GPU is dying? On Windows, when it crashes, the screen turns off, but it’s still responding on the console.

  13. Thank you so much for sharing your setup and your knowledge! I have been able to use your guides to learn a TON and get multiple versions of macOS VM’s working – including ones with GPU passthrough.

    Before looking at your guides, I already had a working stand-alone hackintosh (non-VM) and I was hoping to be able to use the same serial numbers from by config.plist for that system but every time I try to modify parameters in the SMBIOS section the VM stops part-way during the boot process. In otherwords, the Apple logo is displayed and the progress bar proceeds part-way and then stops. For my stand-alone hackintosh I had setup a system that was using the iMac-Pro 1,1 machine type. If I try to replace all of my SMBIOS parameters that appear to relate to this machine type, that’s when I have problems.

    I was wondering if you’d be willing to also share your Clover config.plist? You could feel free to delete various unique serial numbers if you like.

      1. Thanks again for sharing! I was able to use your config.plist after re-generating the serial numbers and everything works fine. I was never able to get the machine type set to iMac-Pro 1,1 so I just gave up on trying to keep my old serial numbers.

        I’m not really sure if there’s much of an advantage to setting the machine type to iMac-Pro vs. iMac anyway. I’m getting similar Geekbench scores with my iMac VM as I was getting with my stand-alone system when it was set to iMac-Pro.

        If there’s ever anything about my system that you’d like me to share just let me know.

        Thanks again!!

  14. Hello Nicholas Thank you for the amazing tutorial I have successfully installed Mojave 10.14.6 in with your guide and I was able to pass through my Vega FE , the tricky part that I have dual E5-2690 v4 CPUs with a total of 28 core and 56 Threads.

    Using this smp 32,cores=16,threads=2,sockets=1 \ I was able to boot with 16 cores and 32 threads as you.
    but Is there anything I can do to pass through all my cores and Threads?

    Edit 1: l already tried -smp 56,cores=14,threads=2,sockets=2 but clover bootloader won’t boot with this flag.

    I also wondering how I can make my main node go to s3 suspend because if you know some of the AMD cards have the rest bug and putting the system in sleep mode and resume it will make the card available for the guest again without restarting the whole machine.
    Waiting patiently for your suggestions 🙂

  15. Hi Nick,
    Most clear guide ever! However, I did everything in the guide installed macOS its working in noVNC. I configured the machine for passthrough. The vm starts without errors cpu and memory is used. I guess it sits on the clover menu but I do not get screen any output. There is a TASK Viewer out put that says

    /var/lib/vz/snippets/ line 6: /sys/bus/pci/devices/0000:01:00:0/driver/unbind: No such file or directory

    I checked the directory and it is linked as

    0000:01:00.0 -> ../../../devices/pci0000:00/0000:00:01.0/0000:01:00.0

    Could you give me any pointers?

    1. What do you have in snippets? What hardware are you passing through? What hostpci config lines did you end up with?

      Are you looking at your physical monitor connected to the guest’s video card, or on VNC? You want to disable the emulated vga and just use your monitor. VNC will not show the graphic card’s output.

      1. Thanks for the help.

        I have a AMD RX 560D gpu.
        My snippet file:

        #!/usr/bin/env bash
        if [ “$2” == “pre-start” ]
        echo 0000:01:00.0 > /sys/bus/pci/devices/0000:01:00.0/driver/unbind
        echo 0000:01:00.1 > /sys/bus/pci/devices/0000:01:00.1/driver/unbind
        echo 1002 67ef > /sys/bus/pci/drivers/vfio-pci/new_id
        echo 1002 aae0 > /sys/bus/pci/drivers/vfio-pci/new_id

        first one is gpu second one is hdmi audio

        hostpci line in 100.conf

        hostpci0: 01:00,x-vga=on,romfile=vbios.bin

        in proxmox config all functions is selected
        I downloaded the firmware from techpowerup an put it in /usr/share/kvm/
        The reason for this is that my gpu card is on pci bridge and I think OS wont let it go during boot.
        I have pci-stub ids in grub too.
        I installed Mojave using vcn.
        Then I configured passthrough
        100.conf has

        vga = none

        I am looking to my physical monitor connected to my AMD gpu card.
        I am booting into proxmox using my integrated Intel igpu

        1. That warning you got:

          var/lib/vz/snippets/ line 6: /sys/bus/pci/devices/0000:01:00:0/driver/unbind: No such file or directory

          That last colon in the ID should be a dot instead, but it looks like you already fixed it in your script?

          Did you apply the irqchip fix in args?

          Are you seeing the Proxmox logo appear on the monitor at the start of guest boot, or is it completely blank?

          1. Try the other connectors on your card because the display might be being sent to one of those instead.

            Try not passing the vbios.bin in the config.

            Can you try vfio-pci instead of pci-stub again and show the config you end up using? It seems like that should have worked. You can diagnose vfio problems by grepping for “vfio” in dmesg or /var/log/kernel.log. If vfio manages to claim the device (lspci -nn -k will show which driver is in use) then you can remove your snippet script.

          2. Both gpu and audio are cliamed by vfio-pci driver
            I tried the DP port instead the HDMI. No go.
            Tried w/ and w/o the rom file. No go
            There are no error messages and no image output to monitor and I am out of options.

          3. You mean you got vfio-pci to successfully claim them during boot? If you are still using pci-stub then I really doubt the video card will enjoy being handed over from pci-stub to vfio-pci. It would be much cleaner for vfio to claim it during boot and it to stay that way.

  16. Are there any major differences between your custom clover build (4920) and the latest clover builds?

    I’m going through the tutorial again building everything myself and i’ve noticed that clover is now v2.5 and the builds are in the 5000’s. When I run kholia’s script with a newer build of clover I get the following error:

    Anything i’m doing wrong? Or should I just stick with r4920?

    1. There isn’t normally anything to gain by upgrading Clover. Since we’re all running the same (emulated) hardware, once it works at all, its job is done.

      The main difference is that AudioDxe-64.efi must be removed to avoid a hang.

      I think newer Clover versions have shuffled around their directory structure, so that build script will not work without being updated to match. Just upgrade Clover after your guest boots macOS by running the Clover installer instead.

  17. Nickolas THANK YOU HATS OFF FOR YOUR GUIDE; it is almost working!!!..

    One lingering killer glitch is that I can’t get any audio from either GPU 1080 passthrough or Realtek on board I have tried the latest kexts from whatevergreen, Lilu and AppleAlC.

    I am using a rearranged 5070 clover as they have now stripped the 64 folder entirely to migrate it to the old 32 bit folder. So for some reason this and the network is not able to establish an IP after resume. Everything else seems glorious! I am able to run machine q35 (4.0) with proxmox 6 and all updates as well!

    How is this possible!? Is it maybe that your setup and guide need to be updated as the latest builds have incorporated fixes ? I am not sure just thought I would try and be helpful.

    Love your work, so happy for your publishing the guide. THANK YOU

    1. I never managed to get HDMI or DisplayPort audio working properly on my system, but I think this trouble is common to all Hackintoshes and not QEMU-specific. There are a wide range of different configuration tools and kexts that promise to solve this (I just never managed to get them to work!)

      My computer doesn’t have onboard audio, so I’ve never tested that with PCIe passthrough either. Instead I’m using a USB DAC on a PCIe-passthrough USB controller, which is working fine.

      I haven’t tried pausing and resuming the VM before so I haven’t had that network issue – maybe you need to explicitly hit the Renew DHCP Lease button in the macOS Network settings to kick it into life?

      1. Alas the network ip cannot be renewed until the entire VM is reset. I feel like I should mention this is actually High Sierra, I just realized I posted here (sorry). None the less since passthrough graphics works how come there is no audio from anything on the system.

        1. Does the network start working again if you set it to “disconnected” in the VM settings and then reconnect it? Are you using vmxnet3 for your network? If so, try “e1000-82545em” instead (you have to enter this by editing your VM config because the Proxmox GUI only offers “e1000” as an option).

          What happened when you passed through your Realtek chip, did macOS detect it at all?

          1. This seems to have fixed my resume issues. Have you any ideas why the passthrough nic stays as disconnected all the time? Also my processor is 2.3 GHz unknown. I have tried fakeid’s which resulted in a crash.

            Also I am very curious if you would now recommend people use machine : q35 as it seems that all can be done now with QEMU 4 and none of the other tweaks are needed any londer in the latest updates… OR am I overlooking something… :

            None the less : Thank you for you work 🙂

          2. What passthrough NIC are you using?

            Adding CPU fakeids doesn’t seem to serve a functional purpose. You may need to switch to a different SMBIOS using Clover Configurator to have that work (one for a Mac that actually shipped with your CPU).

            Some passthrough devices always worked on the new pc-q35-4.0 model. There haven’t been any fixes deployed to this even on the latest Proxmox release though, so if you want to use q35 with troublesome devices you still need to add “-machine type=q35,kernel_irqchip=on” to “args” to get them to work (this brings this setting back to the default value from QEMU 3’s machine model). I’ve updated this post now with the machine I’m using (pc-q35-4.0), that line of my example config was out of date.

  18. I am going to try the network advice you have made here ASAP. Regarding which network VMware vmxnet3 seemed the best as network throughput was quite good and wherever possible I wanted to make use of Proxmox. Though bare metal may be a better option. Either way I am not sure why I can’t get ANY audio to work when I pass through the Realtek chip or the working web driver’d 1080 passthrough… Any ideas; thanks again. 🙂

  19. FYI WordPress kicks me into a new thread every comment I make after 2 reply’s.

    I have been using your advised NIC as edited into the vm’s conf file all is well : THANKS NICK …

    But now I sort of have a bigger issue on my hands.

    It seems either with the mods I made for my PCIE passthrough or USB configs have made my windows boot unable to see anything available on the vfio bus for proxmox … Ie no usb unless I passthrough a controller or reboot. Do I need a hookscript for windows? Can I add more PCIE passthroughs to windows boot options? Thanks again. Sean

    1. I’m not sure what you mean about Windows being unable to see devices, are you saying that your Windows VM can’t start? Are you talking about PCIe passthrough or passing individual USB devices? Is that the same USB controller that you had passed to macOS since the last power cycle?

      1. Yes, it seems that since I added the hookscript and a made alterations vfio has my usb devices available only for a breif time. Now the menu is red (in gui) so I assume I can pass through a controller. Which I do but the system fails to see my usb devices most of the time. In general (and in other words) . the modding seems to have caused me some issues with my other vm’s.

        🙂 Thanks for helping me 🙂

  20. Hi everybody,

    I’m using Virtio Block HDD in Proxmox 6, from Mojave (I’m not sure which version, but I’m testing with 10.14.6), we can use the AppleVirtIO.kext and we have better performance than SATA HDD.

    Only we need to copy this kext to Clover kexts folder in order to can use the Virtio Block HDD in the Mojave Installer (Mojave load the kernel by default, but the Mojave installer not).

    I’m use Dell T5600 and T7610 towers in order to virtualize 2 and 3 VM with GPU NVIDIA GT 710 (HDMI Audio included) and USB (Keyboard and Mouse) passthrough for workstations and it’s working really well.

    I have a custom DSDT for best compatibility: SMBUS, HDEF, HDAU, LPC, UHCI, GFX0 y ETH0 (I can share it if anybody is interested).

    I have only one problem using 16 GB RAM per VM, (I’m using Hugepages: 2). Sometimes the Host hangs.
    Maybe somebody using 16 GB RAM or more per VM can explain how set Proxmox config for this scenario?

    Thanks very much Nicholas for your excelent guide.

  21. Hello, I tried with Proxmox 5.4 with success with an i7 9700k with an Sapphire AMD RX 580… after a lot of research I also could add the iGPU as headless for getting hardware acceleration in Mojave, sometimes it won’t boot (black screen) and after trying again it just works…

    but the thing is that I added another disk to try on Proxmox 6, I installed it in another hard drive and I have no problem with Windows guests, but with my Mojave VM I just can’t get the GPU to work, I tried by adding the -machine type=q35,kernel_irqchip=on as seen in your post, any clues of how to get this done in Proxmox 6, my config:

    args: -device isa-applesmc,osk=”our..” -smbios type=2 -cpu Penryn,kvm=on,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+aes,+xsave,+xsaveopt,check -device vfio-pci,host=00:02.0,addr=0x02,x-igd-opregion=on -machine type=q35,kernel_irqchip=on

    I also tried to change the cores down to 4 and no success, any help will be greatly appreciated!

    1. Not yet! I’ve heard that it doesn’t require anything special to work (maybe just an updated Clover version).

      I’ll be making a tutorial post here once I have it installed on my machine.

  22. Has anyone gotten nested virtualization to work? I’d like to be able to run VMWare Fusion 11.5 inside a VM. When I try to create a VM, I get the following error:

    “This host doesn’t support ‘Intel EPT’ hardware assisted MMU virtualization. Module ‘CPUIDEarly’ power on failed.”

    My ARGS are currently set at:

    args: -device isa-applesmc,osk=”” -smbios type=2 -cpu Penryn,kvm=on,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+aes,+xsave,+xsaveopt,check -device usb-kbd,bus=ehci.0,port=2

    Regardless of args, or if I use a physical host with an AMD or Intel processor, my VM is seen as an iMac 27 inch, Late 2009, Intel Core 2 Duo, which doesn’t meet the minimum system requirements for VMWare Fusion 11.5.

    I tried to run VirtualBox as an experiment, and it would only let me create 32 bit guests.

    Does anybody have any suggestions on how I can get VMWare Fusion 11.5 running correctly?


    1. AFAIK nested virtualisation requires CPU=host, but macOS doesn’t seem to boot with that, at least on my CPU.
