Hi @maryhack2018 - My EFI is attached. This is for Monterey, but I think could also work for Catalina. I use an LG UltraFine 5K display and a RAID array, both via Thunderbolt 3 (hence the mobo choice). I hope this works for you!

Hi, I think it was an issue with the display. I unplugged power and reconnected, and the proper resolutions came back. W6600 working fine now. Incidentally I'll be sending back as it couldn't compete with my older VII. Thanks for the reply.

Yes, agdpmod=pikera is always enabled. I tried deleting that argument and the screen wouldn't turn on. Have also tried 19,1Mac SMBIOS, but it wouldn't boot. Only iMacPro1,1 has worked on my system.

Hi... similar issue. Unable to get beta releases to show (currently on 12.0.1, trying to obtain 12.1 to install a W6600 card). I've tried setting SecureBootModel from disabled to j137, j185, and x86 -- with no change. Also tried setting SMBIOS to iMac17,1 as suggested above (normally for me...

Hello, First time poster here. I attempted to upgrade to 12.0.1 using software update from 11.6 Big Sur. The download worked fine, initial installation was fine (before restart). Then it asked me to re-boot to continue. At that point, a new partition appeared in the EFI boot screen called...
