AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

[alejita27]

I have installed macOS Big Sur in a HP prodesk 400 G1 SSF. everything works for me, except the AMD Radeon RX 550 4GB graphics card, because I don't know how to inject into the OpenCore device properties section.When I was using Clover, it was easy because with fakepciid.kext was injecting the EDID + ati + radeonint + fake pci id ... but with OpenCore, I can't manage to inject these properties ... can someone help me?

Hello, I have the same problem, did you found a solution?
PD. I have a AMD 3100

 

[alejita27]

Yes, you have to extract DSDT with clover and then patch PCI0 where is all the gpu information, no kext necessary... this is the ssdt... I hope works for you

 

[guerreroz01]

but I don't use clover I use OpenCore because I have a Ryzen CPU with a Big Sur MacOs
will you help me? how do I patch it? what do I have to do?

It doesn't work for me because my CPU is a Ryzen 3100, I tried with a lot of config.plist but no one pass the apple logo, It's a shame because only said that I have 7mb of VRAM

If any body please help I will appreciate

Do you know how set the fakeID for GPU 699F to 67FF with Opencore ?

No, in which part of the config.plist you changed the parameters?
