Apple Event: May 7th at 7 am PT
Big Sur 11.0.1 became unbootable.
I have followed instructions including erasing the disk as nothing was working to get it back up.
I have followed this for Big Sur reinstallation: https://support.apple.com/en-us/HT211983.
Terminal based installation is still failing with the same message.
What is the next step here?
MacBook Air 13″, macOS 11.0
Thanks - I'm located in Poland and bought it from premium reseller, as I don't believe we have apple store here (only online possible to purchase directly), so those returns doesn't apply I'm afraid.
I ended up recovering this with my friend's Mac via Apple Configurator 2 - this resolved the booting issue.
I still have initial Screensaver issue though which was the reason I tried the reinstallation :( - described here: https://discussions.apple.com/thread/252087996?login=true&page=2
Many thanks for your reply - unfortunately I do not have Mac with expected spec handy.
My other Mac is MBP 2011 with MacOS High Sierra 10.13.6.
I cannot update any higher then this and cannot install Apple Configurator 2 there either.
Is there anything I would be able to do without this?
If not, I'm assuming that based on Warranty I can bring it back to Apple Store and they would restore it for me?
Have a read over here as per Apple instructions septic to M1
Perhaps this will help:

Thank you, but link you are referring to points to the document I’ve followed already as per my initial post.
Ending up with the very same error I’m afraid.
