Hi there. After upgrading to Catalina, all of a sudden more than one "Macintosh HD" is showing up in my finder. I've attached a screen cap showing info regarding two of them that have appeared on my desktop. It also shows a Disc Utility screen indicating there are multiple Mac HDs showing on my single hard drive.
I am hoping to get back to one HD partition. I have never partitioned this drive before, and now it almost seems like it's somehow been partitioned when the Catalina upgrade took place?
(I also won't get into the problem I'm now getting with frequent crashing and restarts, even when idle. That's a whole other problem!)
I am hoping the community will have some good ideas to cure the Catalina bug I appear to have caught!
