Thank You for your article; its bringing me closer to solution. Catalina crippled my VMWare Fusion
XP installation and disconnected my University provided Microsoft Word privileges. Unfortunately, I proceeded before I read your article and now have (2) hard drives named “Macintosh HD” because I used Time Machine Backup to roll back to Mojave from Catalina. Now Time Machine generates an error because it sees the (2) identically-named hard drives named Macintosh HD. How do I remove the “extra” one, and recover the hd space from the deleted drive? Please advise. Thank You in advance for your help.
