i was in mexico at a wedding. i left my mac unlocked. came back and someone's email address was up on my app store but logged out. i google the email and found her fb profile. i asked her how this could have happened by email and fb message she did not respond. she was not at the wedding. she is not on the brides friend list or the groom. just dont understand. i tried to look at mutual friends on fb but her profile is private and she will not accept my friend request. my mac is bran new.
