PGP WDE + 10.6.5 → MacToast

This kind of stuff is nice to know beforehand.

MOUNTAIN VIEW (Rixstep) — Users of PGP Whole Disk Encryption beware: don't upgrade to Mac OS X 10.6.5 until you've gone and decrypted your HDD. The 10.6.5 install will brick your computer.

10.6.5 seems to overwrite the boot loader (boot.efi) where coincidentally PGP keep data about the encryption. What's curious is that the WDE team were testing every version of the developer release of 10.6.5 and there were no issues. Then 10.6.5 was released and suddenly there were. How surprising.

PGP protect boot.efi against corruption but the good people at Apple decided at the last minute to circumvent this protection. The result? MacToast.

Apple haven't looked into the matter but PGP found a solution.

  1. Get the PGP Recovery CD image from the PGP website (12 MB).
  2. Pick up the script 'PGPwdeEFIUpdate.tgz' at the same time (1.28 KB).
  3. Reboot with the recovery CD, authenticate, press any key but 'D' to start up.
  4. PGP Desktop automagically fixes everything on its own.
  5. Run 'PGPwdeEFIUpdate.tgz' as root.

The security update addresses 56 bugs/vulnerabilities.
