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

[guerreroz01]

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

how did you changed the gpu id in the config.plist?

 

[guerreroz01]

I tried this but didn't change it

 

[inciartet]

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

I didn't have to do that. You're having any problems?

 

[inciartet]

This is how my DeviceProperties section looks

 

[guerreroz01]

Yeah I'm having problems because I'm new with a mac

I put that in DeviceProperties

 

[guerreroz01]

This is how my DeviceProperties section looks

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?

I'm add in my OpenCore config.plist

Change value PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0) to your!
