I set up FileVault a month ago on this new machine. Everything seemed to be working fine. But now when I go to
System Preferences>Security & Privacy>FileVault when logged into a Mobile Account I get a warning that:
You’re using an old version of FileVault.
You’re using an older version of FileVault that encrypts your home directory but not the entire disk. Do you want to keep using the older FileVault?
Legacy FileVault was pre-Lion?!? This machine can't even run Lion, let alone Snow Leopard...
This warning doesn't occur when logged into a Local account. It only pops up when logged into a Mobile account. The way our Macs are setup there is typically just one local
admin user and all other users are mobile Open Directory accounts on our OS X (also Mountain Lion) Servers.
