Greetings, When I go to turn file vault protection on it tell me, "There isnt enough space on your hard disk to turn on FileVault." "Turning on FileVault requires an additional 7.8 GB of free disk space on the volume "Macintosh HD". Try emptying the Trash or deleting files you dont need." I have 67 GB of free space left so I don't understand what the hold up is? My used space on the SSD is 107 GB. Thanks!
