 If you are running any PGP Desktop versions prior to 10.1.2, you must upgrade PGP Desktop prior to upgrading to Mac OS X 10.6.8. 

If you are currently running a version of PGP Desktop 10.1.x or older and upgrade to Mac OS X 10.6.8, you will experience a booting failure due to the Mac OS X 10.6.8 update modification of the boot.efi file.
