Issue



Encryption of the Mac OS X disk on 10.8.2 with PGP 10.2.1 mp4 causes a gray screen to appear with the non bootable icon after a reboot.


Error



After authenticating through bootguard, the Mac screen turns gray and a red non bootable icon is shown.


Environment



Mac OS X 10.8.X

Symantec PGP 10.2.1 mp4


Cause



The drive has had previous drive modifications made to it, such as dual-boot or previous encryption and was not restored back to its pristine state. 

In this scenario, it is difficult to understand what exactly has happened to the disk, but a simple format of the disk does not resolve the issue.


Solution



If the affected drive in question is using a supported file system, and does not contain any unsupported file systems. See here for supported systemshttp://www.symantec.com/docs/TECH198383

If this is the case, re-partitioning the drive and re-installing Mac OSX should resolve this problem. 

Using Disk Utility, create 3 or more partitions to break the current partitions, and then re-assign the disk 1 partition.  Install Mac OSX on the disk and attempt to encrypt the drive.

This should allow the partition tables to be recreated and the disk should be pristine again.
