  • 1.  15-inch, Mid 2012 MacBook Pro + 10.2.1 MP3 = grey screen

    I've tried to encrypt a 15-inch, Mid 2012 2.6 GHz Intel Core i7 MacBook Pro with PGP Desktop10.2.1 MP3. Both times after the Mac reboots after the encryption has run, it boots to a grey screen.
     
    I have been successful with encrypting a 13-inch 2012 with MP3.
     
    Has anyone had success with 10.2.1 MP3 and a 15-inch, Mid 2012 2.6 GHz Intel Core i7 MacBook Pro?

    we have seen this when a failed encryption process (probably on an older version) failed prior and data gets left behind on the first few sectors of the disk.  Try the solution in this KB below

    Another option, if you don't have a secondary Mac to use target disk mode with is to boot the Mac OS X installer disc. Use the Disk Utility. Then select the option to "Secure Erase" the entire drive. an erase re-partition of the drive will not wipe out the PGP WDE mbr information that gets left behind.

    This should allow you to boot the OS again and re-encrypt. If you still have problems, send me a private message and we can investigate the issue. A copy of your system profile in a RTF format would be helpful in that case as well. You can find how to obtain one here using this online guide:

    @mrice23 did you get this issue resolved? I'm very curious to hear where you ended up this this problem.

    Hi Ben,

    We haven't resolved this yet, but it's very sporadic. Only happens on certain MBPs even though we have it work with other MBPs of the exact same model.
