Is there anyway to revert to an older version of PGP Desktop? I installed 10.1.1, and would like to go back to 10.0.1. I'm currently on OSX 10.6.6. I recall there being a boot error with PGP and a OS X update from a while back so I wasn't sure if it's possible to easily revert my version, without losing info and having to decrypt and then reencrypt my drives. Thank you.
I would absolutely not run anything earlier than 10.1.1 on 10.6.5 or higher - you're asking for trouble.
If you do though, you will have to decrypt the OS - PGP must be uninstalled (not dropped in the trash), which triggers decryption.
