Catalina

[key2]

I recently moved from an iMac running Sierra to a 2013 iMac running Catalina 10.15.5 using my TimeMachine backup. Once up and running I noticed thatDisk Utility showed that I have 3 internal HD's when I know that I only have 1 installed.What can I do to fix this issue?

Click View->Show All Devices. Post a picture showing the info.

Catalina now splits the boot partition Container into 2 Volumes:

• A read only volume named Macintosh HD that contains OS system files.
• A read/write volume named Macintosh HD - Data that contains user data and applications.

The volume Paul’s HD was not created by the Catalina installer, so that must have been created by you.

Thanks for your reply Taz Mangus. I have attached 3 screen shots showing the contents of the HD's, Which 2 should I keep and which one should I delete? Could the third one be from my TimeMachine Backup?

These are the only HD's that show up on my desktop.
