Are you using iMacPro1,1 system definition?Hi guys, I had the same issue with the 5700xt being stuck boot while my rx 580 worked fine. Using your latest UEFI worked for me, even though I have a different processor and motherboard, thanks for that.
Now, however, with the 5700xt booted and without freezing, I am getting a small flicker in the top right corner of my screen every minute or so. It is very subtle and quick, but it is recurring. Can this be related to the issues you are having?
Thank you again.
Do you have your iGPU enabled in BIOS? iMac18,3 won't work right without IGPU. The only workaround is to use NoVpaJpeg.kext but that disables hardware decoding.I was initially using the iMacPro, as was in your Config, however it was flickering there as well. I changed it to my usual iMac 18,3 as it is the exact match for my processor. Everything works as before but the flickering continues.
I am using a 2k display connected by displayPort.
