Upgraded to Big Sur and now there are two MacOS Drives mounted on startup

I upgraded to Big Sur from a recently fresh installation of Catalina and everything went smoothly and there appears to be no issues.


BUT, not upon startup, I see two(2) "MacOS" drives mounted on my desktop. I think one may be recovery? I have no idea why and this is very annoying. I have used MacOS from since Mountain Lion and this has never happened before. Please see screenshot for details.



  1. Can I delete one the drives?
  2. If so, how?
  3. If not, can I hide it to stop it from being mounted on my desktop?


Thanks,

Manny

You do not say what exact Mac is this?


Is this the factory SSD or did you user upgrade at some point with a third party SSD?


Did you run a Beta version of the macOS before the final release?



With Big Sur you expect to see a layout similar to:





 Big Sur always boots from a snapshot , a APFS snapshot.


updating to a beta can end up added a new snapshot without deleting the old snapshot.
