Two MacBooks side by side opening each other?
Okay, so I have a new MacBook Pro and tried to transfer my old desktop to the new one, it erased all my custom icons for all my websites and pretty much everything else and now when I open a forum or YouTube or anything online the other one does it too with the safari icon next to finder, both do it to each other. If I sign out of iCloud it doesn't do it. I cannot figure this out. help...please.
