There is an conflict with the Mac OSX 10.7.3 combo update package and Symantec PGP Whole Disk Encryption software. It is important to note, that at the time that this tech article was written. The update is still in beta.
The symptoms are:
- After installing the 10.7.3 update on a PGP WDE encrypted disk and then rebooting you are unable to boot the operating system
- It goes to a spinning wheel with the Apple logo like it's booting
- You are presented with a circle with a line through it
Symantec is aware of this issue and working to resolve the matter
Symantec has identified the issue as a problem. Apple made some changes to their code for the new update which required us to change the way that we copy the bootguard files to the machine after the update.
UPDATE: Symantec has released a PGP Desktop release to address this problem. Please update to PGP Desktop 10.2 MP4 (build 2526) or newer. We will also have this problem addressed in our PGP Desktop 10.2.1 release of the product as well.
