Issue



Beginning with version 9.9 of PGP Desktop, PGP Whole Disk Encryption is supported on the boot drive on Mac OS X systems. Encryption of the boot drive is available on Intel enabled Mac OS X 10.4 and 10.5 systems.

 


Solution




To support PGP Whole Disk Encryption of boot disks on Mac OS X, PGP Desktop creates a new partition (using GUID Partition Table) and puts a new boot loader onto the new partition.

The boot loader that is installed by PGP Desktop does several things: it authenticates users attempting to boot the disk and (when authentication is successful) it calls the Mac OS X boot loader and decrypts the files needed for normal booting of the disk. If authentication is not successful, it does not call the Mac OS X boot loader nor decrypt the necessary files, and thus the disk does not boot.

 

Caution: Apple's Boot Camp product works only when there are two partitions on the disk: one for Mac OS X and one for Boot Camp. Because PGP Desktop adds another partition, Boot Camp does not work on a Mac OS X system with PGP Desktop 10.0 or later.

Other virtualization software (Parallels, for example) work normally on a Mac OS X system with PGP Desktop 10.0 or later. PGP Corporation strongly recommends uninstalling Apple Boot Camp before installing PGP Desktop.
