I recently had the RAM replaced on my Mac. When I got it back and booted it up I discovered that our 2 user profiles have been integrated. Items on wife's desktop have been added to mine and vise-versa. Also, both profiles now share the same Safari link so we can't save our separate logins and passwords. Anyone have any idea how to get the original configuration back? I really don't want to have to schelp it back to the Apple Store.
