If you wish to authorize additional users to unlock the encrypted hard drive, you can run the "fdesetup" tool again with the "-usertoadd" flag in the following manner:įinally, with FileVault enabled, one of the authorized users' credentials will be required to unlock the hard drive if the system is restarted, but you can bypass this requirement by using an authenticated restart instead of a standard restart option. The redirect to the "ist" file (or whatever you would like to name this plist) is an important part of this command, as it will save information about the FileVault setup, including the recovery key, which will be important if at any point you will need to unlock the drive using another Mac. With this command run, the system will enable FileVault and save the designated user as the account authorized to unlock the hard drive.
If you have a server configured, then you likely will have SSH connectivity enabled, so you can log in and run the following command to enable FileVault encryption and authorize a specific user:įdesetup enable -user USERNAME -outputplist > ~/ist The second approach is to use the remote log-in services with an established SSH connection.
As Apple's Back To My Mac service (which offers such a function) is part of iCloud, this may be the easiest way to go for many people. The first option is to use screen sharing, where you log in to the OS X interface to access the system preferences and enable FileVault however, this requires that you have screen sharing enabled. FileVault is generally set up in the Security system preferences, where you can enable and select accounts to allow unlocking of the disk, but if you have your Mac set up as a server and wish to enable FileVault, there are several ways you can do so remotely. FileVault in OS X is Apple's included data encryption technology, which allows for seamless encryption of the entire hard drive to secure your data in the event your computer is stolen.
