I don’t have a backup of Big Sur for my M1 MBA…. It failed installing Beta 3 so… I had to wipe and it’s reinstalling Beta…. Ummm…. Can I not go back to Big Sur? oh well. Love and learn.
Disk Utility and removed the partition groups. It worked this last time, but now I'm hitting other inconveniences such as my iMessages not syncing properly. Its showing messages from 2019, nothing newer.... I may be doing the Big Sur IPSW.
I fixed it. I went back to Big Sur. I have a 2015 MBA i5 that I used for the Apple Configurator 2 app. I wasn’t worried about getting it back up. I don’t mind beta testing.
