If you’re up on your security, you’ve enabled FileVault on any and all Macbooks you have. The problem for an IT admin working off-site or away from the physical machine is that you may need to reboot the computers. With FileVault, a user will need to enter their password first before OS X boots.
With the commands below, you can reboot a Macbook with FileVault WITHOUT NEEDING USER INPUT. This is good for late night work or times when the user is in a meeting.
Simply open you Terminal and to first check if the command is supported, type:
fdesetup supportsauthrestart
If everything looks good, you can then enter the following and reboot:
sudo fdesetup authrestart
