I have always just updated my MacOS over the old one. Also, for my last 4 Macs I just migrated everything to the new machine. I have never done a clean install, not to save time but to just keep things simple.
So Terri, what Folders are not not copying to your new install?
I use that program, too!! It's great!Get yourself a program called AppCleaner. Anytime you want to get rid of a program that doesn't come with it's own uninstaller, use it instead of just dragging to the trash. It'll get rid of the other files that sit out there. Most of the time they're not doing any harm but larger system wide type programs like Microsoft Office, Adobe, etc., tend to come with more bloat than necessary.
