compatibility w/ Linux?

[Lvceo]

Hi Maxime,

I'm trying to do the same for Linux. Do you have any insight?

I followed your Readme, but stuck here

Hi, at what step exactly?

[Lvceo]

Once VM created. After all commands adapted to Linux :

$ VBoxManage modifyvm "MacOSX" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
$ VBoxManage setextradata "MacOSX" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"
$ VBoxManage setextradata "MacOSX" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
$ VBoxManage setextradata "MacOSX" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"
$ VBoxManage setextradata "MacOSX" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
$ VBoxManage setextradata "MacOSX" VBoxInternal2/EfiGraphicsResolution 1920x1080
$ VBoxManage modifyvm "MacOSX" --vram 256

Then Starting the VM with all the parameters you suggested, but NOT VMSVGA in Graphics controller as VirtualBox inform it's "Invalid settings detected". Rest seems to be OK for the VM conf. Running Linux 5.15 on Manjaro. Here is an extract of my VM infos.

The VMSVGA graphics controller seems to be necessary for macOS to boot

[Lvceo]

Do you have any references regarding this point?

[maximedrn]

VMSVGA emulates the VMware Workstation graphics adapter with the “VMware SVGA 3D” acceleration method.

From https://intoguide.com/install-vm-tool-virtualbox-macos-catalina/ Moreover, all the tutorials say to use this graphic controller even if it is reported as an invalid parameter.

Thanks @maximedrn to confirm for VMSVGA. Anyway I'm still not able to go any further right now, VM got stuck at the same point as mentioned before (screenshot). May be it's related to Linux Host. It would work w/ Windows Host but not Linux :thinking: ...

[maximedrn]

From https://najigram.com/2022/01/run-macos-in-virtualbox-on-linux-os/

This tutorial recommends VBoxVGA. Maybe the issue comes from your Linux: something is missing for VirtualBox so macOS cannot run as it should.

[Lvceo]

Thanks again @maximedrn for this comment & screenshot, If this VM is working under Linux, it's a great news. Could you provide me the

$ uname -a
``` output please?

I also noticed the "Chipset Type" is ICH9, which was not the setting mentioned in the first tutorial.

By the way, it seems the VDI connected to SATA port 0, is alone, and there is no boot VDI anymore, is you configuration working that way too?
