The iSchool has FileVault configured on all faculty, staff, and PhD student Mac computers. FileVault is an Apple full-disk encryption technology. Once FileVault is turned on, after a computer is restarted or shutdown, only FileVault-unlock-enabled users or a user with the FileVault Recovery Key can access the drive. Once FileVault is turned on, your UW NetID credentials will continue to allow you to sign into the computer; you should see no noticeable change in behavior.
If you are prompted for a FileVault Recovery Key, please contact the iSchool IT Help Desk.
