10.6: Update renders Mac with PGP disk encryption unbootable

10.6.4 users running PGP Whole Disk Encryption may render their systems unbootable after they update to 10.6.5.
PGP recommends folks to decrypt their drives first, update to 10.6.5 and then re-encrypt. If you have already upgraded and have an unbootable system, burn/use a copy of their Recovery CD to fix. I can verify that using the Recovery CD works.
Procedure:
- Boot the system using the PGP Recovery CD.
- When prompted, authenticate with your passphrase. DO NOT press D to decrypt. Press any key (e.g. spacebar) to boot into Mac OS X normally.
- Once logged into Mac OS X, PGP Desktop will automatically fix the boot issue and you should no longer need the recovery CD.
- Download the script 'PGPwdeEFIUpdate.sh' to your desktop
- Open terminal and navigate to your desktop directory by typing cd ~/Desktop and pressing Enter.
- Type in the command chmod 755 PGPwdeEFIUpdate.sh and press Enter.
- Type in the command sudo ./PGPwdeEFIUpdate.sh and press Enter.
PGP has a tech article about it, and that is the source of this procedure. You can download both the ISO for the recovery CD and the referenced script from links provided there.
