Documents Renamed "Documents - Local" After Turning Off iCloud Sync
I just recently bought a second MacBook Pro. On the first I had Documents and Desktop syncing with iCloud. After setting up the second and turning the feature on, I got a message saying (I'm paraphrasing from memory, didn't screenshot it) that since another computer with the same name ("Clay's MacBook Pro") already existed, it would create a second, nested Documents folder for me inside of iCloud Drive > Documents. That was annoying so I figured I'd turn syncing off on the second computer and change settings then turn it on again later.
After I turned it off, I noticed that my Documents folder was being displayed as "Documents — Local" in Finder in the title bar. Though upon further inspection through Terminal, it was still called just "Documents" in the file system. I ran `ls -la` in Terminal and found a ".localized" file and since it had nothing in it, I deleted it. That didn't change anything.
