I want to turn off file vault but everytime i go to turn it off it says there is not enough free space for it. I freed up about 13 Gigs of space and it still says i need to free up 4084.0 GB, like it had been saying each time i tried. this seems like an error bc my HD is only 60 Gigs does anyone know whats goin on and how i can turn off file vault?
