-igfxvesa disables the intel acceleration. So you have to push amd dgpu profile. I use the attached kext.I gave it a try and it didn't work for me. When my IGPU is enabled with -igfxvesa
as a boot argument, WEG configures it using an Nvidia framebuffer instead of the
usual Intel Capri framebuffer for my 3rd generation CPU. I tried with an HP 8300
configured as a MacPro6,1 in Big Sur, and an HP 8300 configured as an iMacPro1,1
in Big Sur. I tried with IGPU off or on, secondary or primary in BIOS, headless or
Do you define your IGPU in device properties? Which iMac SMBIOS are you using?
This is what I use.
Smbios - imac19,1
Bios - igpu enabled
igpu properties - headless platform id
Kexts - WEG (no shikigva), AMDRadeonpro
Everything works except drm
For drm, add -igfxvesa to boot arg and reboot.
