Setup new Mac Mini with Ventura automatically brough over contents from MacBook Air.

When I wanted to remove items from Mini it automatically also removed the same items from MBAir! = disaster

Fortunately I stopped and was able to restore from Time Machine Backup.

How to stop this linkage??????

I don't want many/most of these items on the Mini! It is to be used for different purposes.

How to use the Mini without automatically changing the MBAir and vice versa???

iCloud is how the same AppleID syncs between device.

Log out of iCloud or uncheck the pertinent items...
