I think you can omit step 2. I’m running Big Sur with a RX6800 on iMac19,1 - didn’t change anything from when I was using my RX580 except to add agdpmod=pikera to the boot arguments. As you’re coming from a 5700XT, you already have that.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I'm still running Catalina and a (by now) somewhat outdated OpenCore version.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.
In that case, pretty sure you just need to update opencore, then update macOS. Then put your new card in and all should be well!
