10.6: Update renders Mac with PGP disk encryption unbootable

Snow Leopard only hint10.6.4 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:

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.

[crarko adds: I haven't tested this one.]
