OK so you know you can use this to get your X299 on Big Sur also? Until the X299 issue is fixed, I'd suggest you do what @rustEswan has done:BTW, I have successfully updated my Catalina drives on an AMD hack and my VERY OLD MacPro 5,1 to BS 11.0.1 without any issues. This X299 specific problem is driving me nuts
- Take your Catalina SSD/NVMe out of the X299, and put it in one of your systems that you know can update to BigSur; the AMD, or the MacPro 5,1.
- Do the upgrade to Big Sur on that second machine
- Once it's complete and you've logged in for the first time, put your X299 EFI on that drive, take it out and return it to the X299
- If your experience is the same as rustEswan, it should now boot fine in the X299
- This will continue to work until, possibly, the next time you need to update again, eg to 11.0.2 or 11.1, whichever comes first.
- That update might work direct on the X299 - maybe it's only complete fresh installs or updates from earlier OS that fail - or it might be you need to use a surrogate system to do all updates.
It's not very convenient, but from the sounds of it it should work.
If your X299 doesn't have a working Catalina install - eg because you already tried upgrading and now it's hosed - then you could do a fresh Big Sur install on your AMD or Mac Pro on to a blank drive, then put that drive into the X299 and it should work.
In other words, the evidence suggests that it's only installation and upgrade of Big Sur that's broken on X299 systems. Day to day running appears to be fine. So anyone who has another hack or real Mac can get around the issue by using it to do upgrade/install duties for the X299.
