For most (almost all) Mac users this will not be a problem. For me, it was a problem when installing the beta macOS Big Sur a few months ago. For a while I was worried that I may have bricked my fairly new MacBook Pro laptop, but I eventually got it sorted out.
I don't like that you apparently can no longer boot into the setup tools and reset a Mac to factory new condition. I had wanted to do this when I could not get LispWorks running with the newest beta macOS - I ended up just deciding to use SBCL until this gets sorted out.

I recently did this on an M1 Mac mini (wiped boot drive + did a clean install of macOS via the internet), so unless I'm misunderstanding what you mean this is definitely possible. https://support.apple.com/en-us/HT201255 https://support.apple.com/en-us/HT201255
- mark_l_watson 5y agoThanks Charles. So, you installed meta macOS Big Sur, then wiped from there? Good to know.
- CharlesW 5y agoI did this on a Mac Mini M1 running a production version (I can't recall which version exactly) of Big Sur.
