After several attempt trying to enable the filevault on the newly fresh nstalled Mac OS X Mountain Lion, the same error messages appears:
There was a problem enabling FileVault.
Problems were encountered with the disk “Mac HD”. Please turn off FileVault, verify and (if necessary) repair the disk with Disk Utility, and try enabling FileVault again.
Each time I've done the followings:
1. I've turned FileVault off.
2. I've erased all partitioned on my hard disk drive, using the USB disk containing the installation files of Mac OS X Mountain Lion.
3. I've created a single Mac OS X Journaled, non-Encrypted partition using the disk utility and instaled the OS on it.
4. I've followed the initial proccess of the newly installed OS by entering the WiFi credentials, AppleID and password and ...
5. I've restarted the system after first boot.
6. I've just enabled the FileVault after logging in without running any application or plugging any device or even using the system for about 6 hours!
But every time the same error occoured.
