Various people have raised issues with filevault enabled users not showing up on the HS login screen. Various ixes exist such as running
sudo diskutil apfs updatePreboot / , however I have an iMac with a fusion drive and hence no apfs, what can I do?Is your Mac connected to a server? If so, try executing fdesetup sync. This will synchronize Open Directory information with FileVault so that the users appear on the login screen. Even if your Mac is not connected to a server, it's still worth trying this command. You could also list what users are authorized to unlock FileVault by using the command sudo fdesetup list (must be executed as administrator and requires admin password).
fdesetup is the command that manages FileVault, so you may also want to see the fdesetup man page and check if any other commands could resolve the issue.
Hope this helps!
Thanks, they are enabled, they just don't show up on the startup screen, Apple have admitted somewhere its an update / rendering issue but the the fix is only on afps, have rebuilt and kicked off encrypting again, will try again if that finally completes, not fast on brand new imacs.
rebuilt and all ok now
