defjux23 Posted April 24, 2021 Share Posted April 24, 2021 I couldn't post into the main thread because I'm a newb, but just wanted to let people know that 11.4 Big Sur Beta I am having no issues with the 6900 XT after upgrading from a Radeon VII. Thanks! Link to main thread: 2 Quote Link to comment Share on other sites More sharing options...
AudioGod Posted April 24, 2021 Share Posted April 24, 2021 Yep it sure does work but disable Whatevergreen as it works better without it for now. 1 Quote Link to comment Share on other sites More sharing options...
defjux23 Posted April 25, 2021 Author Share Posted April 25, 2021 By disable, do you mean just remove the kext? I feel honored getting a message here directly from the AudioGod himself! Thanks! Quote Link to comment Share on other sites More sharing options...

defjux23 Posted April 27, 2021 Author Share Posted April 27, 2021 I can confirm just deleting the Whatevergreen kext would not allow me to boot. Adding it back in and it boots just fine. There is some unusual mouse stutters in certain situations with the 6900 XT that did not exist with the Radeon VII before it. Quote Link to comment Share on other sites More sharing options...
defjux23 Posted April 27, 2021 Author Share Posted April 27, 2021 And removing agdpmod=pikera causes allows for full boot, no screen. And removing agdpmod=pikera and Whatevergreen is a no boot. Both with OC 068 19,1 Z390 Pro EFI.zip - OpenCore v0.6.8, SMBios iMac19,1 I will try OC 068 1,1 Z390 Pro EFI.zip - OpenCore v0.6.8, SMBios iMacPro1,1 (IGPU Disabled) in the near future Quote Link to comment Share on other sites More sharing options...
defjux23 Posted April 29, 2021 Author Share Posted April 29, 2021 Using OC 068 1,1 Z390 Pro EFI.zip - OpenCore v0.6.8, SMBios iMacPro1,1 (IGPU Disabled) and removing agdpmod=pikera and Whatevergreen is a no boot. I think I'm a little over my head in getting the USB to work smoothly again. Quote Link to comment Share on other sites More sharing options...
defjux23 Posted April 30, 2021 Author Share Posted April 30, 2021 Required USB remapping to fix. I believe the USB C connector on the 6900 XT caused some issues. Quote Link to comment Share on other sites More sharing options...
