After encrypting a Mac OS X system with PGP WDE, you are able to successfully authenticate at the PGP BootGuard screen, but Mac OS X fails to load and displays a continuous spinning wheel.
During encrypting or decrypting a Mac OS X system with PGP WDE, Disk I/O errors are reported in /var/log/kernel.log.
- This issue appears to occur with MacBook Pro laptops configured with any Solid State Drive and also configured with “64-bit Kernel and Extensions”. When you start encrypting/decrypting the drive Disk I/O errors appear in /var/log/kernel.log when other Disk I/O is present. To determine if you have a 64 bit Kernel and Extensions enabled, see Apple KB article reference below.
- Spinning hard drives appear not to exhibit this problem – both 500Gb and 750Gb disks have been tested.
- Even though the Mac OS X systems use the Intel Sandy Bridge chipset, this appears not to be an Intel Sandy Bridge specific issue. Internal tests with older hardware with OSX 10.6.6 running with 64bit kernel have also reproduced the issue
This issue is fixed in PGP Desktop 10.1.2 SP3 (build 50) and higher which can be downloaded by logging into your Symantec FileConnect account.

Symantec Corporation is committed to product quality and satisfied customers. This issue is currently being considered by Symantec Corporation to be addressed in a forthcoming version or Maintenance Pack of the product.
