Hi! Thanks for helping me. Trying to turn on FileVault I get a message saying: There isn't enough space on your hard disk to turn on FileVault. Turning on FileVault requires an additional 132.2 GB of free space on the volume "Macintosh HD". Try emptying the Trash or deleting files you don't need. Finder says that hard drive "Macintosh HD" has a capacity of 499.76 GB and that 180.42 GB are available. Am I to understand that to run FileVault I would need 312.62 GB (132.2 + 180.42 GB) empty on a 499.76 GB hard drive?! Seems crazy! Might this be related to Parallels 6 or something? Recommendations? Thanks!
