I turned on filevault a week ago. now, almost everytime i shut the mac down i get a message saying something along the times of "filevault is using more space than required.... do u want to correct this" then option of ok or cancel.... something like this. i say ok and it sort-itself out and shuts down fine. is there anyway of avoiding this or doing it as automatic? otherwise it wont shut down before i acknowledge the question....pretty dumb.
