Fix a "unapproved Caller" Securityagent Message in Mac OS X

Morning into the company by the Japanese branch of Beauty call, said Mac hard disk encryption often need to enter the hard disk encryption password before you can log in, I think it should be hard disk encryption after the user has not been added to the license, so every login system to be verified. So remote to the user's computer, ready to add the user license in the hard disk encryption settings, the admin account unlocked when the "unapproved Caller" error occurred:

This error causes no way to use admin to unlock the permissions to add a user license, the following is a documented workaround:

Boot into Safe mode:

1. Reboot the MAC and immediately hold down the SHIFT key, continue holding shift until the loading bar appears
2. Let the Mac boot into Safe Mode, which'll automatically dump caches
3. When completed, go to the? Apple menu and choose "Restart" to reboot the Mac as normal.

Long press the SHIFT key to enter Safe mode, automatically clean up the cache, and then restart, the problem is a perfect solution.
