Macbook reset factory settings after restart?
I'm new to the world of Macs and recently got my first Mac, a 2007 Macbook Pro with OS X 10.4 Tiger. I had it for a few weeks and this morning I shut it down before school. When I got home and booted up everything was reset to factory settings. All of my saved pictures and my entire iTunes library were gone. Does anyone have any clue as to why this happened and possibly have a way to get everything back?
Also, I should be getting Snow Leopard in the mail any day. Do you think I will have that problem with Snow Leopard as well? Thanks!
MacBook Pro, Mac OS X (10.4.11)
