BigSir has done things in a different way from all earlier os's. The main
system is a snapshot that is readonly and very hard protected. If you look at
Macintosh HD< you should see two volumes within it, one the system volume and
the other data. I expect you can only change the data one. Also, you might want
to temporarily turn off System Integrity Protection. Do some googling. Or you
might just want to create a new user if it is user settings that are causing
issues.
The other option I can think of is to use a USB or connected external drive
with a BigSir installer on it. I have actually been able to boot my a Macintosh
from a time machine drive to do major work, but that was with Catalina, so
things might have changed.
Best wishes,
Jonathan Cohn
