Hey gang, been watching this thread since the start — was stoked to see driver support come around, but of course then there were no cards to be had. I'm an idiot and finally bought one from a scalper, because I apparently hate money and need to get rid of it right away.
I'm still running Catalina and a (by now) somewhat outdated OpenCore version. Current setup includes a 5700xt and WEG + agdpmod=pikera, SMBIOS iMac 19,1
I believe these will be my steps, please tell me if I have something wrong:
1) Update OpenCore to the latest stable release
2) Change SMBIOS to something else?? If so, do I need to generate a serial number to match?
3) Update Mac OS to Big Sur 11.4
4) bung in the new GPU and boot the whole thing up
I'm sure I've missed something.
