I was reading a recipe the other night and my Macbook started ticking, the screen went black, then a white screen came up with a blinking envelope with a "?" in it. This happened once before when the computer was about a year old. I took it to the Apple store and they repaired it. The problem is that store is 2 hours from me. Does anyone know what this is and how to fix it? I have hit different keys and nothing takes me out of that screen. My biggest concern is my pictures and music are on it. I plan to buy another computer (anything but Apple) if I can't come up with a fix for this. Is there any way to get my music on my Iphone onto another computer? Thanks for any help.
