I am a fairly new Mac user and just got my first MBP in August. It has been going great and I have had very few errors where Safari had to "close unexpectedly" Anyway....I had my computer on sleep with only Safari and Excel running and when I opened it up there was a gray box with a message that said "you need so restart you computer immediately. to do this hold down the gray button" there was no explanation of the problem or what could have happened that caused this message. The only thing it had underneath it was the same exact message in a few other languages....WHAT COULD THIS POSSIBLY BE ???
