Ever since I reformatted my Mac to a fresh mountain lion, truecrypt has been showing the rainbow wheel when it is decrypting and encrypting volumes. The pre-reformat version didn't do this. I GPG verified the download. I suspect foul play. The download wasn't over https. Maybe the NSA/FBI/CIA has a rouge version running to spy on the ****izens ? Or am I just crazy, It's never done this before. edit: it does not do this spin when you eject the volume via the system "eject" button, and then dismounting. But technically proper procedure is to just press dismount. So that traces the issue(?) to something in Apple's dismounting.
