Excellent way to solve the problem - thanx a lot to everyone and JofArnold for the "easy" way.
Only one little note for those not so apt in Terminal but with the same problem. These are the two lines you have to call in Terminal to move the two culprits to your desktop:
mv /Volumes/[YOUR LION-DISK]/System/Library/Extensions/PGPwde.kext /Volumes/[YOUR LION-DISK]/Users/[YOUR USER-SHORTNAME]/Desktop
mv /Volumes/[YOUR LION-DISK]/Library/PriviledgedHelperTools/com.pgp.framework.PGPwde /Volumes/[YOUR LION-DISK]/Users/[YOUR USER-SHORTNAME]/Desktop
i ditched PGP long time ago due to the constant problems when i updated the system.
right now i have exact same problem you guys are having on a mid 2011 macbook air that has NEVER had PGP installed. it has apples own Filevault 2 turned ON....anyone else having this problem?
i can start in recovery mode and i have even re-installed lion via recovery mode already without any luck.
when it boot after re-installing lion it prompt me for the apple filevault pass..i type it and then i get the same gray screen with circle and slash over and its hanging there forever
any ideas on what to try next?
I ditched PGP Whole Disk Encryption, BUT there's still some PGP software on there.
To see for yourself if that's the case on startup, do cmd+V for the visual boot mode (loads of commands scroll past on a black screen - it's used for debugging) and wait for it to freeze. Then scan through last few lines - ther's a pretty good chance it will have "PGP" somewhere. If so, follow the advice above. If not, I can't help you - really hope you find a solution!
BTW the reason it happened to me is that Time Machine transferred PGP from another machine. So even though I use FileVault2, the PGP app was still there.
UPDATE: PGP's gui uninstaller doesn't work for me (see ik8sqi2's wiki link above for more info) So for now I'm just keeping those files in their new out-of-the-way position until I find the time to go through and remove everything. Symantec have certainly made themselves no new friends today...
Well,I would say you start in all usual places, where bad coded software products left their tracks:
Kernel Extensions in
Compare the content to a fully functional 10.7.2 system - since it's becomming harder to understand which ones are from Apple and which ones are not.
In general I recommend a great tool for checking on extras within the Library folder : http://khiltd.com/software/consultants_canary
oki... found the problem.
i overlooked that i had to cd to /Volumes/hardrivename as the / files are the files in the recovery volume...hehe
so i found :
and deleted them. how they ended up there is a mystery but it must have been via timemachine (that i dont use any more) or maybe even .me syncs? or i might have moved some folders from my desktop compter in past that i dont remember. ...pgp desktop app was not installed on the computer at all and i will never get close to that again now that i hopefully have gotten it all removed once and for all.
anyway...now everything works fine again! thanks a lot for the help!
Removing the latter two did the trick; I was able to complete this in the recovery partition as per JofArnold's reply below as well... Thanks for the assist!
To clean up, run the following in Terminal after a successful boot:
sudo /Applications/PGP.app/Contents/Resources/uninstall_pgp.pl --uid 501
That will run the PGP uninstaller script as the primary user, and clean up the rest of the PGP files.
ik8sqi2, thank you so much for the solution. It worked for me. Phew! Just like you, I thought I've gotten rid of all those bloody PGP files a while ago, but it seems like one can't quite fully get rid of it .
For those less familiar with Lion (like I was just an hour ago), you can mount your root partition using Disk Utility (even if it's encrypted with Filevault) once you boot off of a recovery partition (hold Cmd-r when powering on your Mac). This is obvious once you know about it, but it took me a little while to figure out.
I didn't even realize that I had PGP installed. Just went thru removing all the peices using all the instructions on this thread.
My problem now is that after I got everything working again, before finding this thread, with a fresh install and then pulling my data in from a backup drive I tried to use Filevault again. This time instead of going thru the whole install, then pull the data in process I used disk utility to turn encription off on my boot drive. As a side effect of that process my backup drive is no longer mountable.
Invalid Volume Header @ 0: incorrect block type
Invalid Volume Header @ 1999736188416: I/O error
disk2 is not a CoreStorage volume
Any sugestions for fixing the backup drive without wiping it?
And I thought I was done with all this. At least after removing all that PGP stuff and rebooting my backup drive is working again. Sounds like a fun project for this weekend. This time I think I'll save the important things in icloud so I don't have to sweat it out durring that long coundown when restoring.
Wow! This is scary stuff. So I had better be REAL careful before upgrading to Lion. Uninstalling PGP 10.2.0 even after decrpting everything using the uninstaller BEFORE upgrading to Lion may not even work.
Thanks for the warning and Fix. I will make sure I have the necessary time, food and alcoholic beverages before attempting! Or just chicken out all together!
