Today, I went in to change my password on my account on my MacBook and when I logged out and logged back in to the same account (there is only one on the computer) it was like a completely restored computer. There was a ? mark where the iMovie HD was, it deleted the icons for Word, PowerPoint, and Excel off my dock (they were still in the apps folder) and also took out Photo Booth. When I went into iTunes, there is nothing. I can use Spotlight to find some the songs on my computer, but when I click the "iTunes Music Library Folder", there is nothing in there. All the customization settings, i.e. trackpad settings, screen saver settings, and the background all reverted to what it was like brand new. Even iChat thinks its new and there are no contacts or bookmarks in Safari. I'm kind of afraid to sync my iPhone to it. Any Ideas as to what is going on? Remember I have only ever had one user account on this computer and all I did today was change the password to it. It was fine before the restart then like this after. Is there any way to do a restore to a few days before like on Windows? I've also been using Apple Comps for years, so I'm not a total Newb at this kind of stuff.
