I'm pretty sure iGPU (HDMI...) is possible with upcoming WEG.
I'm running for about 2 weeks now with iGPU on Z490 -
So I'm attaching my config.plist.
Mind that you'll need (as any of other configs here) to generate your unique machine values. (UUID, SystemBoard etc)
Also attached are debug builds of Lilu and WhateverGreen I've compiled that fixes the black screen of 10.15.5
(future readers: replace those...
Just a quick update. latest commits to WhateverGreen fix patching of IGPU on 10.15.5 :) (still no release yet).
Tomorrow I'll post the plists and kext for UHD630. It seems to be working for me now with HDMI output.
One note for those who go the AMD 5xxx route - remember to add agdpmod=pikera.
Are you trying macOS Catalina 10.15.5? did you update to latest BIOS. look above to some of the screenshots.
Also, keep in mind that once you past that stage an dGPU (non-intel/UHD630) would be helpful. I've yet to see a Desktop 10th reported using only UHD630.
In my case I don't yet have a DP display or DP-HDMI cable so I still have no output from HDMI.
Also tried booting Mojave but it seems it'll require different patching.
Btw, I see the AAPL,pci locations are different than the ones by the OpenCore guide. are those correct? are they the same...
