Installing macOS 13 Ventura on Proxmox 7.2 – Nicholas Sherlock (2023)

This macOS 13 Ventura installation tutorial has been adapted by ProxmoxKholia's OSX-KVM ProjectjLeoyzen OpenCore configuration for KVM. You can get the full source code of my OpenCore versionon my github here.


I assume you already have itProxmox 7.2Furnished. You also need a real Mac to compile the installer and get the OSK key.

Ventura now requires your CPU to have support for itAVX2, so your CPU should be for Intelat least as new as Haswell. However, I added itCryptexFixup kextto circumvent this limitation and allow Ventura to be used even on CPUs that do not support AVX2 (and only support SSE 4.2). Please note that AMD graphics card drivers will not work in this situation and other applications that assume AVX2 is present may also fail! Please take a look...Leame von CryptexFixupfor details.

Modern AMD CPUs also support AVX2 and should work with this guide.

If you are from Monterey your host must havea functioning THW(timestamp count) because otherwise if you give the VM more than one core, macOS will watch the divergence between the cores and panic when it sees the time going back. To check this, run the following in Proxmox:

dmesg | grep -i -e tsc -e Taktquelle

On a working host you will see the following:

tsc: refined TSC clock source calibration: 3399.998 MHz clock source: tsc: mask: 0xffffffffffffffff max_cycles: 0x31024cfe468, max_idle_ns: 440795307017 nsclocksource: Cambiado a clocksource tsc

On a broken host you will see:

TSC Sync [CPU#0 -> CPU#1]: Measured 3358870891203288 TSC warp cycles between CPUs,Turn off the TSC clock.tsc:Failed to mark TSC as unstable due to check_tsc_sync_sourceClock source: Cambiado is a clock source hpetkvm: SMP VM created on host with unstable TSC; TSC guest is not trusted

If you have a defective TSC,This is a possible solution. Sometimes you can just power cycle the host to resync the TSCs (especially if your server has high uptime).

Step One: Create an Installation ISO

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

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

xcode-select --install

If you are building the ISO on Linux, you should run this command (these are the package names for Ubuntu or similar distros, they may need to be adjusted on other distros):

sudo apt install qemu-utils do

Now run the following in the terminal in the root of OSX-KVM:

cd scripts/venturamake Ventura-recovery.img

This will download the Ventura installer from Apple's software distribution servers and create oneVentura-recovery.imgfile for you. Upload this file to the Proxmox ISO save directory (usually/var/lib/vz/template/iso). Although we're putting it in the ISO directory so we can later use it with Proxmox's ISO picker, this is a raw disk image rather than an actual ISO.

If you are building the installer on macOS,You can create a full installer instead of a recovery, which means macOS doesn't need to download Ventura files during installation and therefore doesn't need an internet connection. Just ask it to create Ventura-full.img instead:

cd scripts/venturamake Ventura-full.img

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

Prepare an OpenCore image

Download the OpenCore.iso.gz filethe latest version in my repository (you needv19or higher), double-click it to unzip it and upload it to the Proxmox ISO storage at/var/lib/vz/template/iso. Although it has an .iso file extension, it's actually a disk image.

Get the OSK authentication key

macOS checks if it runs on real Mac hardware and refuses to boot on third-party hardware. You can get around this by extracting an authentication key from your actual Mac hardware (the OSK key). Save the first block ofCode C of this pageas smc_read.c. At a command prompt, change to the same directory as this file and run:

xcode-select --install # Si aún no tiene gccgcc -o smc_read smc_read.c -framework IOKit./smc_read

It prints the 64-character OSK for you. Notice it.

(Video) How-to: Install MacOS Monterey in Proxmox 7 (Hackintosh)

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

Create the virtual machine

Create a new virtual machine from the Proxmox web UI as shown below.

On the Virtual Machine Options page, ensure that Use tablet as pointer is set to Yes (this is the default setting).

On the VM Hardware page, add a second DVD drive in IDE0 and configure it to use your Ventura-full.img.

Do not try to start the virtual machine yet. First establish an SSH connection to your Proxmox server so that we can make some changes to the configuration files.

Edit /etc/pve/qemu-server/YOUR-VM-ID-HERE.conf (e.g. with nano or vim). Add this line, making sure to replace the previously extracted OSK in the correct place:

argumentos: -device isa-applesmc,osk="EL-OSK-TÚ-EXTRACTO-VA-AQUÍ" -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 -cpu host,vendor=GenuineIntel,+invtsc,+hypervisor,kvm=on,vmware-cpuid-freq=on

A USB keyboard is added here as macOS does not support the standard QEMU PS/2 keyboard. Disabled MSI for USB driver to fix QEMU panics when passing USB 3 devices ACPI PCIe hotplug support was disabled to fix VMs with passthrough devices.

Make sure the arguments are all on one line!

You can remove the "+invtsc" feature from the -cpu list if your CPU doesn't support it or if you want to migrate a running virtual machine between Proxmox nodes.

With AMD, the installer may restart while loading or the loading bar may not appear. In this case, replace "-cpu host" with "-cpu Haswell-noTSX" (I had to do this on AMD EPYC 7R13).

Now find the lineswhich define the two "ISOs" (ide0 and ide2) and remove the ",media=cdrom" part from them. Add ",cache=unsafe" instead. This will treat them as hard drives instead of DVD drives.

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

Agent: 1args: -dispositivo isa-applesmc,osk="..." -smbios type=2 -dispositivo usb-kbd,bus=ehci.0,port=2 -global nec-usb-xhci.msi=off -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off -cpu host,vendor=GenuineIntel,+invtsc,+hypervisor,kvm=on,vmware-cpuid-freq=onballoon: 0bios: ovmfboot: order=ide2 ;virtio0cores: 4cpu: Haswellefidisk0: local-lvm:vm-100-disk-0,efitype=4m,size=4Mide0: local:iso/Ventura-full.img,cache=unsafe,size=14Gide2: local:iso/OpenCore -v18.iso,caché=inseguro,tamaño=150Mmaquina: q35speicher: 4096meta: creación-qemu=6.2.0,ctime=1655001118nombre: macos-venturanet0:virtio=...,bridge=vmbr0,firewall=1numa: 0ostype: otroscsihw : virtio-scsi-singlesmbios1: uuid=...sockets: 1vga: vmwarevirtio0: local-lvm:vm-100-disk-1,cache=unsafe,discard=on,iothread=1,size=64Gvmgenid: ...

Configure Proxmox

In Proxmox run "echo 1 > /sys/module/kvm/parameters/ignore_msrs" to avoid boot loop during macOS boot. To persist this change across Proxmox restarts, run:

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

Install Ventura

Now start your VM, it should boot with the OpenCore boot selector:

Press Enter to launch the Install macOS 13 Ventura entry and the installer should appear. (If your keyboard doesn't work, please exit the Proxmox console page and re-enter it.)

Installing macOS 13 Ventura on Proxmox 7.2 – Nicholas Sherlock (9)

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

You can now exit Disk Utility from the main menu (Disk Utility > Exit Disk Utility) and we can begin the installation!

After the first phase of installation, the virtual machine will reboot a few times in quick succession, and each time you do this you'll have to manually select the "MacOS Installer" entry (the second one here, with the hard drive icon). .to continue with the installation. It will not be automatically selected for you:

If your keyboard is not responding on this screen, exit and reopen the Console tab in Proxmox. If you see a prohibition sign like this, press the reset button on the virtual machine to try again:

Now the installation is almost complete and the macOS installer entry is gone. So choose the name of your main drive to boot from (mine is called Main).

It will restart a few more times, so keep selecting the Main entry until you finally launch Ventura!

Answer the initial setup questions and you're signed in! Note that you should postpone signing in to your Apple ID until you have done soSet your Mac serial number to OpenCore(Because otherwise, a Mac will be added to your Apple ID with the default shared serial number in my OpenCore image.)

Installing macOS 13 Ventura on Proxmox 7.2 – Nicholas Sherlock (18)

Please note that after the first launch it will be very slow for a few minutes while the system performs cleanup tasks.

Make the OpenCore installation permanent

We are currently booting with OpenCore from the included OpenCore ISO. Let's install it to disk instead. Open Terminal and run "diskutil list" to see what drives are available.

Installing macOS 13 Ventura on Proxmox 7.2 – Nicholas Sherlock (19)

Use "sudo dd if=<source> of=<dest>" to copy the "EFI" partition of the OpenCore CD and overwrite the EFI partition on the hard drive. The OpenCore CD is the small (~150MB) drive with only one EFI partition, and the main disk is the one with the large (>30GB) Apple_APFS "container" partition.

In my case, these EFI partitions were named disk2s1 and disk0s1 respectively, so I ran "sudo dd if=/dev/disk2s1 of=/dev/disk0s1" (note that if you type these names wrong, you'll end up with the wrong floppy disk! and you have to start the installation again!).

Now turn off the virtual machine and remove the OpenCore and Ventura installation drives from the Hardware tab. On the Options tab, edit the boot order to set your virtio0 drive as the first drive. tarnishing. If everything went well, you should see the OpenCore boot menu and you can select your "main" drive to start Ventura:

sleep management

I found that I couldn't wake Ventura from sleep with my mouse or keyboard. If you encounter the same issue, you can either disable system hibernation in Ventura Energy Saver settings to avoid the issue, or you can manually wake the VM from hibernation in Proxmox by running:

qm monitor SU-VM-ID-HIER

Editing the OpenCore/EFI configuration

The Configuration.pdf, which explains the OpenCore config.plist file, can be found throughoutwith the release of OpenCore on my GitHub.

How to mount your EFI partition on macOSIn order for you to be able to edit your config.plist, first check the "handle" of your EFI partition in the terminal:

~$ diskutil list/dev/disk0 (external, physical): #: TIPO NOMBRE TAMAÑO IDENTIFIADOR 0: GUID_partition_scheme *512.1GB disk0 1: EFI EFI 209.7MB disk0s1 2: Apple_APFS Container disk1 511.9GB disk0s2

How to mount it:

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

Now you can edit/Volumes/EFI/OC/config.plistwith your favorite text editor to make your changes. (TextEdit isn't a great option as it likes to put quotes in the file and otherwise break things, there are some dedicated plist editors like XCode.)

If you cannot start macOS, you can edit config.plist using the UEFI Shell option in the OpenCore boot menu.

Type "FS0:" and press Enter to open the first available file system, then run "edit EFI\OC\config.plist" (if the file is not found, try going to another file system like fs1: to switch). When you're done editing, press Ctrl+Q to exit, "Y" to save, and then "Exit" to return to the OpenCore menu. You must restart for the changes to take effect.

If you want, you can easily edit the config.plist from your Proxmox host.If you boot from an attached OpenCore.img file, you can mount that file as a disk on the host. If you instead boot from the virtual machine's disk, it should be in raw format instead of qcow2 so that it can be mounted (e.g. typical use of LVM or ZFS).

# Install an OpenCore:losetup image --partscan /dev/loop0 /var/lib/vz/template/iso/OpenCore-v15.img# or a disco arranque from VM:losetup --partscan /dev/loop0 / dev/zvol/tank/vms/vm-100-disk-1mount /dev/loop0p1 /mnt

Now the contents of this first partition are available in /mnt, so you can edit /mnt/EFI/OC/config.plist in your favorite editor. When finished, do this to unmount the drive:

dismount / min
losetup --separar /dev/loop0

Automatic start

In the config.plist you can set Misc/Boot/Timeout to a non-zero value to have the default boot option be selected automatically after this delay in seconds. I disabled this by default as it causes the ISO installer to re-enter its main menu instead of proceeding to the second phase of the install.

You can set the default startup option by pressing Ctrl + Enter.

(Video) Part 2 - How-to: finish configuring MacOS Monterey Virtual Machine on Proxmox (Hackintosh)

detailed boot process

To start macOS in verbose mode to diagnose startup issues, in the OpenCore boot menu, press Cmd+V before pressing Enter to start macOS (you don't need to hold down the key).

If you experience a kernel panic during boot and the reboot is too fast to read, edit config.plist to add "debug=0x100" to the kernel arguments.

Change screen resolution

To change the screen resolution of macOS 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 one of the modes offered by the OVMF system menu (press F2 when launching guest boot and select "Device Manager/OVMF Platform Settings" to see what resolutions are available).

video performance

Since guest video acceleration is not available for macOS, video performance is poor.

In Google Chrome in the guest, you need to disable the "Use hardware acceleration when available" setting to troubleshoot non-drawing or flickering elements (especially video). Safari might be the better option.

The "Screen Sharing" feature built into macOS offers much better frame rates and latencies than Proxmox's browser-based VNC console. So if you have an actual Mac that you want to act as a display console, you can enable it in the "Share" settings of the VM and connect to the VM using your Mac's Screen Sharing app instead:

Screen Sharing also appears to support VNC clients like RealVNC, so you should be able to connect from Linux or Windows consoles using RealVNC.

The true magic wand for video performanceis to go through a compatible graphics cardmit PCIe-Passthrough(AMD cards only). This provides near-native performance. You can read more about how I use PCIe passthrough in my own

USB transfer

Since I plan to use this as my main computer, I'd like to use a USB keyboard and mouse connected directly to Proxmox instead of sending my input through the VNC web console.

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

qm> info host usb
Bus 3, address 12, port 6, speed 480 Mb/s
Class 00: USB device 8564:1000, mass storage device
Bus 3, address 11, port 5.4, speed 12 Mb/s
Class 00: USB device 04d9:0141, USB keyboard
Bus 3, address 10, port 5.1.2, speed 12 Mb/s
Class 00: USB device 046d:c52b, USB receiver
Bus 3, address 9, port 14.4, speed 12 Mb/s
Class 00: USB device 046d:c227, G15 GamePanel LCD
Bus 3, address 8, port 14.1, speed 1.5 Mb/s
Class 00: USB-Dongle 046d:c226, G15-Gaming-Keyboard

In this case, I can add my keyboard and mouse to the USB transfer by exiting qm and 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 in the VM configuration for you. You must reboot for the new settings to take effect.

You can also pass USB devices by passing a full USB controller with Proxmox's PCIe pass-through feature, offering much better compatibility.

Odd core numbers

If your host CPU is AMD, it can have a core count that is divisible by 3, e.g. B. 6 cores. macOS doesn't like that the number of cores isn't a power of 2 (1, 2, 4, 8), but it doesn't care about the number of odd sockets.

So to go beyond 6 cores overall, configure the VM for 3 sockets and 2 cores per socket.

Fixed "guest boots in UEFI shell".

If your guest boots to the UEFI shell instead of showing the OpenCore boot menu, especially if you just upgraded OpenCore to a newer version, you need to edit the guest's UEFI boot entries to fix this.

At the beginning of guest boot, press F2 to enter guest UEFI setup.

First we delete the old entries. Select the Boot Maintenance option and then Boot Options -> Remove Boot Option. Use the spacebar to check any old Clover or OpenCore entries (avoid enabling the EFI Internal Shell option, you want to keep it!). Select "Confirm Changes and Exit".

(Video) AMD/NVIDIA GPU Passthrough in Window 11 - Proxmox Guide

We will now add the correct entry for OpenCore again. Select Add launch option. Navigate through the device tree to EFI/OC/OpenCore.efi and select it, name this new option "OpenCore" or similar. Confirm changes again and exit.

Go to Change Boot Order and move OpenCore up. Confirm changes and exit.

Now go back to the main menu and select Reset and it should successfully boot into OpenCore this time.

Fix iMessage

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

Disable SIP (System Integrity Protection)

You can disable SIP by selecting the Recovery option from the OpenCore start menu and then using the top menu to open and run Terminalcsrutil disable --no-internal. Then restart.

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


Sometimes you need to update OpenCore to a new version to support a new macOS update. I'm assuming you don't have any customizations to config.plist that you want to save.

Take a snapshot first! It's great to be able to roll back if something goes wrong.

If you can still start macOS, you can update it from the guest. Follow the instructions in the "Edit your OpenCore/EFI configuration" section to mount your EFI partition. Then you can delete the EFI folder there and replace it with the one from file of my version of OpenCore(You'll probably need to empty the Trash first to make room for the new folder.) You're done!

If you cannot start macOS, unzip and download thenew Open-Core ISOgo to the Proxmox ISO Store instead. Add a new CD drive to the VM using this ISO. Then in the Proxmox terminal edit the configuration of the VM (in/etc/pve/qemu-servidor) 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 macOS with the new OpenCore drive. On macOS, you can now follow the instructions in the Make OpenCore installation permanent section to install the new OpenCore image on your primary macOS drive, after which the OpenCore drive can be detached from the virtual machine.

Upgrade von macOS Monterey

Make a backup or snapshot of your system first!The ability to roll back if the update goes wrong is a real lifesaver.

You need to update OpenCore to my v19 version before updating, use the section above to do that. After updating that, reboot to ensure you can still start Monterey.

If you are using PCIe pass-through devices (especially graphics cards), you should disable them and set "vga:vmware" instead so that you can install via the Proxmox web console from another computer during the upgrade. This prevents installation issues caused by unstable graphics card passthrough, especially host crashes caused by an AMD reset error.

If your CPU is AMD, replace the "-cpu" argument in your VM's argument line with the new one:

-cpu Haswell-noTSX,vendor=GenuineIntel,+invtsc,+hypervisor,kvm=on,vmware-cpuid-freq=on

Intel CPUs should work with -cpu host

Yes nowYour CPU supports AVX2You can use an upgrade to VenturaSoftware-Updateor from theAppstorejust like on a real Mac.

If you don't see the update, your SIP mode might be set to Apple Internal. You can check this by running "csrutil status" in the terminal.

(Video) Proxmox GPU/PCIE passthrough

To fix this, restart your VM and select Recovery from the OpenCore menu. Open the terminal and run "csrutil enable --no-internal“ („csrutil disable --no-internal' is fine too), then boot back into macOS and try again.

Another way to upgrade is to get aFull installer or recovery of Venturaand use it to install Ventura (installing via Monterey will update Monterey and leave your user data intact).

If your CPU does not support AVX2,you will do itto havesince then creating a full/recovery installerI have not enabled the Monterey/Big Sur kernel patchThis would allow the Ventura App Store app to run directly from macOS.
