Installing macOS 12 “Monterey” on Proxmox 7

This tutorial for installing macOS 12 Monterey has been adapted for Proxmox from Kholia’s OSX-KVM project and Leoyzen’s OpenCore configuration for KVM. You can get the full sourcecode of my OpenCore release on my GitHub here.

Requirements

I’ll assume you already have Proxmox 7 installed. You also need a real Mac available in order to fetch the OSK key.

Your Proxmox host computer’s CPU must support SSE 4.2, so for Intel your CPU must be at least as new as Nehalem, which was the first CPU generation to bear the “Core” i5/i7 branding. Older CPUs will cause Illegal Instruction crashes when apps/extensions attempt to use these missing instructions.

Modern AMD CPUs also support SSE 4.2 and will work with this guide.

First step: Create an installation ISO

Download my copy of the OSX-KVM repository using the download button, and unzip it:

https://github.com/thenickdude/OSX-KVM

First we need to install some build requirements. If you will be building the installer ISO on macOS, open up the Terminal and run this command to install the commandline tools:

xcode-select --install

If you’re building the ISO on Linux, you instead need to run this command (these are the package names for Ubuntu or similar distributions, they may need adjustment on other distributions):

sudo apt install qemu-utils make

Now in the Terminal, from the root of OSX-KVM, run:

cd scripts/monterey
make Monterey-recovery.img

This will download the Monterey installer from Apple’s software distribution servers and build a Monterey-recovery.img file for you. Upload this file to your Proxmox’s ISO store directory (typically /var/lib/vz/template/iso). Although we’re putting it in the ISO directory so that we can use it with Proxmox’s ISO picker later, this a raw disk image rather than a true ISO.

If you’re building the installer on macOS, you can build a full installer instead of just a recovery, which will mean that macOS won’t have to download Monterey files during installation, and so won’t require an Internet connection. Simply ask it to build Monterey-full.img instead:

cd scripts/monterey
make Monterey-full.img

This option is not available when building the installer on Linux.

Prepare an OpenCore image

Download the OpenCore.iso.gz file from the newest release in my repository (you want v15 or newer), double click it to unpack it, and upload it to Proxmox’s ISO store at /var/lib/vz/template/iso. Although it has a .iso file extension, this is actually a hard disk image.

Fetch the OSK authentication key

macOS checks that it is running on real Mac hardware, and refuses to boot on third-party hardware. You can get around this by reading an authentication key out of your real Mac hardware (the OSK key). Save the first block of C code from this page as smc_read.c. In a command prompt, change into the same directory as that file and run:

xcode-select --install # If you don't already have gcc
gcc -o smc_read smc_read.c -framework IOKit
./smc_read

It’ll print out the 64 character OSK for you. Make a note of it.

Every Mac uses the same OSK, so don’t be surprised that it doesn’t look like a random string!

Create the VM

From the Proxmox web UI, create a new virtual machine as shown below.

In the Options page for the VM, ensure that “use tablet for pointer” is set to “Yes” (this is the default).

In the Hardware page for the VM, add a second DVD drive at IDE0, set it to use your Monterey-full.img or Monterey-recovery.img.

Don’t try to start the VM just yet. First, SSH into your Proxmox server so we can make some edits to the configuration files.

Edit /etc/pve/qemu-server/YOUR-VM-ID-HERE.conf (e.g. with nano or vim). Add this line, being sure to substitute the OSK you extracted earlier into the right place:

args: -device isa-applesmc,osk="THE-OSK-YOU-EXTRACTED-GOES-HERE" -smbios type=2 -device usb-kbd,bus=ehci.0,port=2 -global nec-usb-xhci.msi=off -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off

A USB keyboard is added here because macOS doesn’t support QEMU’s default PS/2 keyboard.

MSI has been disabled for the USB controller to fix QEMU panics when USB 3 devices are passed through.

ACPI PCIe hotplug support needs to be disabled for VMs with passthrough devices since QEMU Q35 machine model 6.1, which is what that final argument does. (You could instead choose Q35 6.0 for your Machine type on the Hardware tab). If you haven’t updated your QEMU to version 6.1 yet then remove this argument from the args. (Proxmox 7 ships with 6.0 and updated to 6.1 later on)

Ensure the args are all on a single line!

We also need to add a -cpu argument. If your host CPU is Intel, add this to the end of the “args” line:

-cpu host,kvm=on,vendor=GenuineIntel,+kvm_pv_unhalt,+kvm_pv_eoi,+hypervisor,+invtsc

This will pass through all of the features that your CPU supports. OpenCore’s config will pretend to macOS that the CPU’s model name is Penryn for compatibility.

If your host CPU is AMD, or the above argument doesn’t work for you, use this more-compatible alternative:

-cpu Penryn,kvm=on,vendor=GenuineIntel,+kvm_pv_unhalt,+kvm_pv_eoi,+hypervisor,+invtsc,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+avx2,+aes,+fma,+fma4,+bmi1,+bmi2,+xsave,+xsaveopt,+rdrand,check

This pretends that your CPU is Penryn, which will keep macOS happy even if your host CPU is AMD, and adds a bunch of newer required and optional CPU features on top. Features that your host CPU doesn’t support will be ignored (a warning will be printed to the console during launch with qm start 1xx), but note that macOS won’t work without SSE4.2 support.

You can remove the “+invtsc” feature from the list if your CPU doesn’t support it, or if you want to be able to migrate a running VM between Proxmox nodes.

Now find the lines that define the two “ISOs” (ide0 and ide2), and remove the “,media=cdrom” part from them. Add “,cache=unsafe” in its place. This will treat these as hard disks rather than DVD drives.

Save your changes, return to the Options tab, and change the boot order to put IDE2 (the OpenCore image) first. Your final VM configuration file should resemble this:

args: -device isa-applesmc,osk="..." -smbios type=2 -device usb-kbd,bus=ehci.0,port=2 -cpu host,kvm=on,vendor=GenuineIntel,+kvm_pv_unhalt,+kvm_pv_eoi,+hypervisor,+invtsc -global nec-usb-xhci.msi=off -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off
agent: 1

bios: ovmf

efidisk0: vms-ssd-enc:vm-171-disk-1,efitype=4m,size=1M
ide0: isos:iso/Monterey-full.img,cache=unsafe,size=14G

net0: virtio=...,bridge=vmbr0,firewall=1

scsihw: virtio-scsi-pci
smbios1: uuid=...
sockets: 1
vga: vmware

Configure Proxmox

On Proxmox, run “echo 1 > /sys/module/kvm/parameters/ignore_msrs” to avoid a bootloop during macOS boot. To make this change persist across Proxmox reboots, run:

echo "options kvm ignore_msrs=Y" >> /etc/modprobe.d/kvm.conf && update-initramfs -k all -u

Install Monterey

Now start up your VM, it should boot to the OpenCore boot picker:

Press enter to boot the “Install macOS Monterey” entry and the installer should appear. (If your keyboard isn’t working, leave the Proxmox Console page and re-enter it)

OpenCore’s “OpenCanopy” boot picker

If you built a recovery installer, the icon will instead be an image of a hard disk and be labelled “MacOS Base System”.

Our virtual hard drive needs to be erased/formatted before we can install to it, so select the Disk Utility option. Follow the steps below to format the disk:

Now you can quit Disk Utility from the top menu (Disk Utility > Quit Disk Utility), and we’re ready to begin installation!

After the first stage of installation, the VM will reboot 2 or 3 times in quick succession, and each time you must manually pick the “macOS Installer” entry (the second one here, with the hard disk icon) to continue installation. It will not be selected for you automatically:

If your keyboard isn’t responding on this screen, exit the Console tab in Proxmox and re-enter it. If you get a “prohibited” sign like this appearing, hit the Reset button on the VM to try again:

Now the installation is nearly complete and the macOS Installer entry disappears, so pick the name of your main disk to boot (mine’s called Main).

There’s just one more reboot to come. Afterwards pick the “Main” entry again and this time you’ll finally boot into Monterey!

Answer the initial install questions, and you’ll be logged on! Note that you will want to hold off on logging into your Apple ID until you’ve configured your Mac’s serial number in OpenCore (because otherwise a Mac with the default shared serial number in my OpenCore image will be added to your Apple ID).

It works!

Note that it will be really sluggish for a few minutes after the first boot while the system performs housekeeping tasks.

Make the OpenCore install permanent

We’re currently booting using OpenCore from the attached OpenCore ISO. Let’s install that to the hard drive instead. Pop open Terminal and run “diskutil list” to see what drives we have available.

Use “sudo dd if=<source> of=<dest>” to copy the “EFI” partition from the OpenCore CD and overwrite the EFI partition on the hard disk. The OpenCore CD is the small disk (~150MB) that only has an EFI partition on it, and the main hard disk is the one with the large (>30GB) Apple_APFS “Container” partition on it.

In my case these EFI partitions ended up being called disk1s1 and disk0s1 respectively, so I ran “sudo dd if=/dev/disk1s1 of=/dev/disk0s1” (note that if you get these names wrong, you will overwrite the wrong disk and you’ll have to start the installation over again!).

Now shut down the VM, and remove both the OpenCore and the Monterey installer drives from the Hardware tab. On the Options tab, edit the boot order to place your virtio0 disk as the first disk. Boot up. If everything went well, you should see the OpenCore boot menu, and you can select your “Main” disk to boot Monterey:

Sleep management

I found that I was unable to wake Monterey from sleep using my mouse or keyboard. If you encounter the same problem, you can either disable system sleep in Monterey’s Energy Saver settings to avoid the issue, or you can manually wake the VM up from sleep from Proxmox by running:

qm monitor YOUR-VM-ID-HERE 
system_wakeup
quit

Editing your OpenCore/EFI settings

The Configuration.pdf that explains the OpenCore config.plist file can be found along with the OpenCore release on my GitHub.

To mount your EFI partition in macOS so you can edit your config.plist, first check the “identifier” of your EFI partition in the terminal:

~$ diskutil list
/dev/disk0 (external, physical):
   #:                   TYPE NAME              SIZE       IDENTIFIER
   0:  GUID_partition_scheme                  *512.1 GB   disk0
   1:                    EFI EFI               209.7 MB   disk0s1
   2:             Apple_APFS Container disk1   511.9 GB   disk0s2

Then you can mount it like so:

sudo mkdir /Volumes/EFI
sudo mount -t msdos /dev/disk0s1 /Volumes/EFI

Now you can edit /Volumes/EFI/OC/config.plist with your favourite text editor to make your changes. (TextEdit is not a great choice because it likes to insert curly quotes into the file and otherwise break things, there are some dedicated plist editors available such as XCode).

If you’re unable to boot macOS, you can edit the config.plist using the “UEFI Shell” option in the OpenCore boot menu instead.

Enter “FS0:” and press enter to open up the first available filesystem, then run “edit EFI\OC\config.plist” (if the file isn’t found, try switching to another filesystem like fs1:). When you’re done editing, press control+Q to exit, “Y” to save, then run “exit” to return to the OpenCore menu. You need to reboot for your changes to take effect.

If you prefer, you can edit config.plist from the comfort of your Proxmox host instead. If you’re booting from an attached OpenCore.img file, you can mount that file as a disk on the host. If you’re booting from the VM’s disk instead, it must be in raw format in order to be mounted (e.g. typical LVM or ZFS usage) rather than qcow2.

# Mount an OpenCore image:
losetup --partscan /dev/loop0 /var/lib/vz/template/iso/OpenCore-v15.img
# or a VM boot disk:
losetup --partscan /dev/loop0 /dev/zvol/tank/vms/vm-100-disk-1

mount /dev/loop0p1 /mnt

Now the contents of that first partition are available in /mnt, so you can edit /mnt/EFI/OC/config.plist in your favourite editor. When you’re done, do this to unmount the disk:

umount /mnt
losetup --detach /dev/loop0

Automatic boot

In config.plist, you can set Misc/Boot/Timeout to a non-zero value to allow the default boot option be chosen automatically after that delay in seconds. I’ve disabled this by default because it causes the installer ISO to re-enter its main menu instead of continuing the second stage of installation.

You can set the default boot option by pressing control+enter on it.

Verbose boot

To boot macOS in Verbose mode to diagnose boot problems, at the OpenCore boot menu press Cmd+V before pressing enter to boot macOS (you don’t need to hold it down).

If there is a kernel panic during boot and it reboots too quickly to be read, edit config.plist to add “debug=0x100” to the kernel arguments.

Changing screen resolution

To change macOS’ screen resolution, you need to edit the UEFI/Output/Resolution setting in config.plist, the default is 1920×1080@32.

You should be able to change this to any of the modes that the system OVMF menu offers (hit F2 at the start of guest boot and choose “Device Manager/OVMF Platform Configuration” to see which resolutions are available).

Video performance

Because there is no guest video acceleration available for macOS, video performance is poor.

In Google Chrome in the guest you will need to toggle off the setting to “use hardware acceleration when available” to improve issues with elements not being drawn or flickering (especially video). Safari may be a better choice.

macOS’s built in “Screen Sharing” feature offers dramatically better framerates and latency than Proxmox’s browser-based VNC console, so if you have a real Mac to act as a viewing console, you can enable that in the VM’s “Sharing” settings and connect to the VM using the Screen Sharing app from your Mac instead:

Apparently Screen Sharing is also compatible with VNC clients like RealVNC, so you should be able to connect to it from Linux or Windows consoles using RealVNC.

The real magic bullet for video performance is to pass through a compatible video card using PCIe passthrough (though note that macOS now only supports a handful of very old NVidia cards). This offers near-native performance. You can read more about how I’m using PCIe passthrough on my own installation here.

USB passthrough

Since I want to use this as my primary computer, I want to use a USB keyboard and mouse plugged directly into Proxmox, rather than sending my input through the web VNC console.

Proxmox has good documentation for USB passthrough. Basically, run “qm monitor YOUR-VM-ID-HERE”, then “info usbhost” to get a list of the USB devices connected to Proxmox:

qm> info usbhost
Bus 3, Addr 12, Port 6, Speed 480 Mb/s
Class 00: USB device 8564:1000, Mass Storage Device
Bus 3, Addr 11, Port 5.4, Speed 12 Mb/s
Class 00: USB device 04d9:0141, USB Keyboard
Bus 3, Addr 10, Port 5.1.2, Speed 12 Mb/s
Class 00: USB device 046d:c52b, USB Receiver
Bus 3, Addr 9, Port 14.4, Speed 12 Mb/s
Class 00: USB device 046d:c227, G15 GamePanel LCD
Bus 3, Addr 8, Port 14.1, Speed 1.5 Mb/s
Class 00: USB device 046d:c226, G15 Gaming Keyboard

In this case I can add my keyboard and mouse to USB passthrough by quitting qm, then running:

qm set YOUR-VM-ID-HERE -usb1 host=04d9:0141
qm set YOUR-VM-ID-HERE -usb2 host=046d:c52b

This saves the devices to the VM configuration for you. You need to reboot to have the new settings apply.

You can also pass through USB devices by passing through an entire USB controller using Proxmox’s PCIe passthrough feature, which gives much better compatibility.

Odd core counts

If your host CPU is AMD, you might have a core count which is divisible by 3, like 6 cores. macOS doesn’t like it if the core count isn’t a power of 2 (1, 2, 4, 8), but it doesn’t mind odd socket counts.

So in order to pass 6 total cores, configure the VM for 3 sockets and 2 cores per socket.

Fixing “guest boots to UEFI shell”

If your guest ends up booting to the UEFI shell instead of showing the OpenCore boot menu, especially if you’ve just updated OpenCore to a new version, you’ll need to edit the guest’s UEFI boot entries to fix this.

At the very start of guest boot, hit F2 to enter guest UEFI settings.

First we’ll remove the old entries. Choose the Boot Maintenance option, then Boot Options -> Delete Boot Option. Use the spacebar to tick any old Clover or OpenCore entries (avoid ticking the EFI Internal Shell option, you want to keep that!). Select “Commit Changes and Exit”.

Now we’ll add the correct entry for OpenCore back in. Select Add Boot Option. Navigate through the device tree to EFI/OC/OpenCore.efi and select it, name this new option “OpenCore” or similar. Again Commit Changes and Exit.

Go to the Change Boot Order and move OpenCore to the top. Commit Changes and Exit.

Now back out to the main menu and choose Reset, and you should successfully boot into OpenCore this time.

Fixing iMessage

iCloud and the App Store should already be working for you, but for iMessage support you must follow these steps to mark your network adapter as built-in:

https://dortania.github.io/OpenCore-Post-Install/universal/iservices.html#fixing-en0

Disabling SIP (System Integrity Protection)

You can disable SIP by selecting the Recovery option from the OpenCore boot menu, then use the top menu to open the Terminal and run csrutil disable --no-internal. Then reboot.

This may be needed to run unsigned kexts or perform other hacks.

Upgrading OpenCore

Sometimes you need to update OpenCore to a new release in order to support a new macOS update. I’ll assume you don’t have any customisations to config.plist you want to save.

First take a snapshot! It’s great to be able to roll back if something goes wrong.

If you’re still able to boot macOS, you can update it from within the guest. Follow the instructions in the “Editing your OpenCore/EFI settings” section to mount your EFI partition. Then you can delete the EFI folder in there and replace it with the one from the OpenCoreEFIFolder.zip file from my OpenCore release (you’ll probably need to empty the trash first to make room for the new folder). You’re done!

If you aren’t able to boot macOS, unpack and upload the new OpenCore ISO to Proxmox’s ISO store instead. Add a new CD drive to the VM that uses that ISO. Then in Proxmox’s terminal edit the VM’s config (in /etc/pve/qemu-server) to replace “media=cdrom” with “cache=unsafe” for the OpenCore drive. Now on the “Options” tab, change the boot order to put the new OpenCore drive first.

Start the VM and boot into macOS using the new OpenCore drive. From within macOS you can now follow the instructions from the “Make the OpenCore install permanent” section to install the new OpenCore image to your main macOS disk, after which the OpenCore drive can be detached from the VM.

Upgrading from macOS Big Sur

First make a backup or snapshot of your system! Being able to roll back when the upgrade goes wrong is a real lifesaver.

You’ll need to update OpenCore to my v15 release before the upgrade. You can follow the instructions in the “Editing your OpenCore settings” section above to mount your EFI disk. Then you can replace the OpenCore files in the mounted “EFI” disk with the ones from the OpenCoreEFIFolder.zip file in my newest OpenCore release.

Reboot to make sure that you can still boot Big Sir.

If you’re using any PCIe passthrough devices (particularly video cards) you’ll want to disable those and set “vga: vmware” instead, so you can install using Proxmox’s web console from a different machine during the upgrade. This avoids installer problems triggered by flaky video card passthrough, especially host lockups caused by the AMD Reset Bug.

Now you can upgrade to Monterey using Software Update or from the App Store like you would on a real Mac.

If the update fails to appear, your SIP mode might be set to “Apple Internal”. You can check this by running “csrutil status” in the Terminal.

To fix this, reboot your VM and at the OpenCore menu select Recovery. Open up the Terminal, and in there run “csrutil enable --no-internal” (“csrutil disable --no-internal” is fine too), then reboot back into macOS and try again.

  1. Hi, thanks for this great description.
    I have set up Monterey with GPU Passthrough on Proxmox and it is working fine.
    Just one thing is annoying. When I activate Start on boot in Proxmox options it will not work. Screen stays dark and I have to use my Laptop to restart the VM. After Restart Monterey boots and works fine.

    Any Idea how to solve this?

      1. I am not very experienced with Linux.
        I made the check with following command and get this result:
        dmesg | grep -i “error”
        [ 1.459990] RAS: Correctable Errors collector initialized.
        [ 6.876127] EXT4-fs (dm-1): re-mounted. Opts: errors=remount-ro. Quota mode: none.
        [ 7.085793] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
        [ 7.161414] b43-phy1 ERROR: FOUND UNSUPPORTED PHY (Analog 12, Type 11 (AC), Revision 1)
        [ 7.161496] b43: probe of bcma0:1 failed with error -95
        [ 8.105034] nvidia-gpu 0000:41:00.3: i2c timeout error e0000000
        [ 8.105219] ucsi_ccg: probe of 0-0008 failed with error -110

        Is theire a better way to check with dmesg?

        1. Mentioned in there is nvidia-gpu, the Nvidia host driver. Ideally you would be assigning your GPU to vfio-pci on boot before the Nvidia driver loads, so that it never gets used.

          Did you assign your GPU to vfio-pci in your modprobe config? If not, find a guide for that.

  2. There seems to currently be a problem in the data that macOS downloads during installation if you choose the Recovery method for installing Monterey. Installation fails with this message:

    https://i.imgur.com/vFlA9DT.png

    Even using working OpenCore and Recovery images from 6 months ago also replicates the problem, so it has to be an issue with the new data the Recovery is downloading.

    I’m investigating why that’s happening

  3. I get the error:

    The file “bootbase.efi” couldn’t be opened because there is no such file.

    How to fix that problem?

    1. I too had the error about bootbase.efi not being found and it stalled out.

      I believe this is a problem that is common to trying to upgrade unsupported Macs that have had their original SSDs replaced and the installer is trying to upgrade some firmware component that doesn’t pass validation, but I don’t know if this 100% the case. In the situation of the real macs, simply having an original SSD detected somehow gets past this situation but not everyone had their original SSD on hand.

      Regardless, I managed to bypass this issue by seeing that this problem only started recently, likely started with Monterey 12.4.

      I managed to mangle my way to get the full 12.3.1 installer downloaded (Mr. Macintosh or MDS) and pushed into the proxmox ISO directory (16GB). It installed successfully and things are looking OK, and now I’m walking through the next steps.

      MacOS software update installed 12.4 successfully for me after that. Looks like it crashed the entire proxmox system during the update but I had a similar crash installing Windows 11 too, but now after a couple of VM reboots everything looks OK.

      Also I have 12.5 beta 3 on deck to see if Apple has addressed this installation issue but now that I went 12.3.1 -> 12.4 successfully I’m going to leave it for now.

  4. Can you elaborate on passing through usb host controller pci devices. Simply adding them in proxmox doesn’t seem to work. I assume there’s something more to be done in OpenCore like for the sound chip, but everything I search for just shows how to do single usb devices and only mentions you can do it the other way without giving any instructions.

    Also , I’m having an issue that I can get video passthrough to work, but I cannot boot if I remove the VMWARE video option. Anyone have a fix? I am using an nvidia 650ti (Which hasn’t had any other problems , supposedly a memory leak has made them unstable for other people) (That’s on Big Sur by the way,)

  5. Gigabyte X570 Aorus , Ryzen 9 3900x ,16GB Ram. I followed everything to the latter. But after running the VM, it just stuck/freeze at Apple Logo, there is no progress bar displayed here. Anyone having same problem? What is the solution(s). Thanks

    1. I Fixed my error to change the CPU cores
      My CPU(i7-12700f) hase 12 cores but its stuck on Apple logo than I set to 8 cores than its working fine
      So try to change the cores number

  6. Hey,

    does anyone know, why the graphic is so slow?
    Do you really need a strong graphics card or can you use Remote Desktop as with Windows servers?

    1. That’s because there is no video acceleration available.

      You can use macOS’s built-in screen sharing feature, it’s much faster than the Proxmox Web UI.

      But the only way to get proper 2D/3D acceleration is to PCIe passthrough a compatible GPU

      1. “You can use macOS’s built-in screen sharing feature, it’s much faster than the Proxmox Web UI.”

        But how can I connect to mac like RDP? And where can I activate it?

        1. System Preferences, the Sharing button.

          You may be able to connect to it with a generic VNC client.

  7. I’ve narrowed down why the Recovery installer is broken right now, it looks like it’s accidentally downloading the new 21F2092 build of macOS during install, which is for M2 Macs.

    Seeing if I can fix this now

  8. Thanks for the guide. I am using a Ryzen 3900X and I have found that it does not like the cpu args: +pcid and +fma4 so I left them out. Also, I can’t seem to get my GPU to passthru without enabling the display=Vmware compatiable. Also is the normal warning at startup:
    no efidisk configured! Using temporary efivars disk.

  9. Hi Nick thanks for all you do – any ETA on this fix?

    “it looks like it’s accidentally downloading the new 21F2092 build of macOS”

    1. If you want a quicker fix, you can use my previous tutorial to install a Big Sur VM, then use that VM to build a Full Installer for Monterey. The Full Installer isn’t affected by this problem.

  10. Update: like other commentators have mentioned, I was able to get Monterey going by installing Big Sur and upgrading to Monterey. Thanks!

  11. For anyone who has the smc_read execution issue which shows error “smc_read.c:24:56: warning: ‘kIOMasterPortDefault’ is deprecated: first deprecated in macOS 12.0 [-Wdeprecated-declarations]”, you have to modify “kIOMasterPortDefault” to “kIOMainPortDefault” according to

    https://github.com/kovidgoyal/kitty/issues/3719

  12. damn seems it does not work anymore, after I execute the smc_read, it shows:

    “…” [removed – nick]

    Monterey 12.4
