Unable to Boot Mac OS 10.7.5 after installing PGP
I have Mac OS 10.7.5.
Darwin Kernel Version 11.4.2
When I reboot, I am taken to the PGP login. I am able to successfully login with the passphrase. However once I log in, I am taken to the Apple logo. Eventually the Apple logo is replaced with a circle with a line through it.
The only way I am able to get my data is to mount the hard drive using another system that has PGP installed. Then I can put in my passphrase and unlock drive.
If I uninstall PGP, then I am able to use computer again.
This has happened on two different macbook pros. Some of the computers are not affected.
Is there a list of incompatible hardware or anything that may be causing the conflict? I am trying to figure out why this is affecting me on some systems but not others.
