Hey Bustycat, thanks for your sharing, I found your comment by searching.

I'm building a macOS 11.4 hackintosh, I use the same Graphics card as yours, but I encounter a black screen issue after `IOConsoleUsers: gIOScreenLock` log, I've tried many solutions but nothing helped. Could you share your EFI files with me? looking for your response :)

Nothing special actually. I simply added WEG. Did you also connect to HDMI?

I appreciate getting your response. Yes, I have tried both HDMI and DP ports but didn't help. I also flashed GOP to support UEFI so my bios can turn of CSM. I can launch the installer and select a disk to install, but I encounter the black screen issue during the installation phase after seeing a log "OConsoleUsers: gIOScreenLock".
I see several successful cases that use HD 7850, but both of them use Intel CPU, I'm not sure if this issue is related to AMD when composing with HD 7850.

I didn’t flash mine to GOP as the UEFI support of the H61 motherboard is not mature enough.
 
I just replace HD 7850 with RX 570, then everything works...
