Filevault Not Turning On

[jenski]

Hello!

Currently, we have a policy that is set to turn on Filevault with both individual & institutional keys. Unfortunately, Filevault will only work when used on a retina display Mac. When tested on a MBAir & a 13in Mac, it asked for password confirmation on restart, but did not turn on Filevault.

Has anyone else run into this issue?

The policy was created via the JSS. It is set to enable current or next user.

It sounds like the Recovery HD partition is not in place on those systems, can you confirm that? It will show up if you run "diskutil list" in Terminal.

Unfortunately, this is also not working on one of our other retinas. I've run the diskutil list & it does, in fact, look like there isn't a recovery hd on the non-file-vaulting computers.

Try running Disk Utility on the drive to check for any possible errors. We've seen cases where if the drive needs any repairs, even if they seem minor, FileVault will not start encryption. This is actually normal for most FDE products, since you really don't want to encrypt a drive with problems on it.

recovery hd is required for filevault. if it's not there, start with that.
mm2270 is correct as well, though- any disk errors will stop the FV2 setup since it does a quick check before beginning it's work.
