If you have a modern Mac, there’s almost no reason not to use FileVault, the all-disk encryption that’s built in to OS X. It doesn’t slow the computer down, it keeps your data safe and – if the machine is switched off – then even if a baddie pulls your drive he’s stuck with a useless chunk of silicon.
And now Apple has added one more convenience for the cautious user: authenticated reboots.
Usually when you start up a FileVault-enabled computer, you’ll be prompted for a password to unlock your disk, before it’ll even boot into the OS. This is also true when you restart, so you can’t just tell the computer to reboot, walk away and come back with everything just as you left it. Now, with “authenticated restart,” you can. Apple:
This allows you to restart a FileVault-enabled system without requiring an unlock during the next startup. Note: Macs running OS X Mavericks should update to v10.9.1 or later to perform an authenticated restart.
If you have one of these computers, you’re good to go:
- MacBook Air (Late 2010) and later
- MacBook (Late 2009) and later
- MacBook Pro (Mid 2009) and later
- Mac mini (Mid 2010) and later
- iMac (Late 2009) and later
- Mac Pro (Late 2013)
