Tried so many inject ways from clover to open core.
I don't think I can make any further investment anymore.
Long story short:
I'm using OpenCore, followed This Guide to install Mojave 10.14.6.
Trying to FakeID R9 290 with SSDT GPU SPOOF guide. FAILED.
My final goal is getting iGPU headless...
I've been searching for solution quite a while but can't seems to find any answer.
I'm running on 10.13.6, here's some kexts I installed in Library/Extensions.
I also attached my clover config below if needed.
