Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

Macintosh HD and Macintosh HD Data?

Why two I appear to have two drives following the Catalina update?


I erased the disc and installed fresh yet this is what appears in disk utility.


Anyone?

Thanks

iMac 27" 5K, macOS 10.15

My inquiry is different. I upgraded from Majove to Catalina , but then I determined that Catalina was not working as satisfactorily for my needs as Mojoave. I then reinstalled Mojave. However, I still have both a HD and HD-Data folder characteristic of Catalina, but not Mojave. The computer works fine so far, but the HD-Data did not exist on my Mojove system (according to earlier versions of Mojave backed up on my external hard drive) before I upgraded to Catalina and then reverted to Mojave.


My questions are:

  1. Are there risks to my computer in keeping this current configuration, which was designed for Catalina?
  2. If there are, how do I remove the HD-Data folder?


Thanks for any guidance that you can offer.
