Desktop shows icons from my other computers
Running High Sierra 10.13.6 I have two Mac computers, a Macbook Air (early 2015) and a Mac Mini (l2014), and they both share their desktops with iCloud.
My Macbook Air shows icons from the Mac Mini even though the desktop computer is 120 miles away, and the two computers are not currently directly connected. I'd like to remove all the icons on the Macbook Air for folders etc. that are on only the Mini. But when I connect remotely to the Mini and tell it to share it's screen, and then delete a duplicate icon from one screen, it is deleted on the other screen.
Oddly, not all the folders on the Mini are duplicated on the Macbook Air.
How to I remove the duplicate icons for folders on one computer without also deleting them on the other?
