How to uninstall TrueCrypt 7.1a from my Mac cleanly? The instruction on TrueCrypt website is Windows-only.
TrueCrypt installer is an
mpkg file that contains multiple
pkg files within it. You can right click the installer in
Finder, open package contents and see the
pkg files. Essentially, it installs MacFUSE and the TrueCrypt application. If you examine the
mpkg file with a tool like Pacifist, you'd see the list of files it installs and the locations.
TrueCrypt does not come with an uninstaller on OS X. But there are at least two ways to attempt to uninstall it completely:
According to help on the
TrueCryptforum, uninstalling it is a matter of removing MacFuse and the TrueCrypt app (you need to have an account on that forum to see this post):
sudo rm -rf /Applications/TrueCrypt.app
Try UninstallPKG to uninstall any application installed with a package (requires OS X 10.8 or later). I haven't used this, and do not know if it will be able to remove MacFUSE and TrueCrypt.
Once you've done this, check the list of files/locations reported by Pacifist, see if any of those are still around and remove them.
Are you seeing a installation folder or an .exe file. Either way, the installation would not have gone anywhere, and I think it should safe to delete either. After you complete the delete, you can run a search for "TrueCrypt" to see if anything is left, but I doubt it would be.
However, I ran a check on TrueCrypt (truecrypt.org) and there is an OSX installer. If you have that, there may be more to be done. But you said you got a Windows installer, so I'll leave it at that.
