when MacBook powers up... folder with a flashing question mark
my friend needs glasses and had adjusted the size of the screen on my macook, when i asked her to put it back the way it was before... she had no clue what she had done and then started messing with screen display and resolution, and apparently who knows what else because when i went to look at it later after she had left, the only thing that would come up is a flashing folder icon with a question mark inside it ~ please help... what do i do???
Is this a good question?
