[QUOTE="MacInWin, post: 1836284, member: 396914"] I'm not sure that is possible to do. The issue is that Catalina split the drive into two Volumes, one named MacintoshHD and the other MacintoshHD Data. I don't think TM knows how to undo that split. To recover from Catalina back to Mojave, I think it's up to you to boot into recovery, use Disk Utility to reformat the drive and create just one volume on it again, and then let TM put the system back. It may even be faster to reinstall Mojave at that point and then do a restore of you files when it boots and offers Migration Assistant to bring in your data. Maybe somebody who has done that can chime in here and correct me or verify what I said? [/QUOTE]
