The first is just to show you where the installation is at this moment:

n102:~ hendrikwindel$ brew info truecrypt truecrypt: stable 7.1a http://truecrypt.org/ Conflicts with: fuse4x Not installed From: https://github.com/Homebrew/homebrew/commits/master/Library/Formula/truecrypt.rb ==> Dependencies Build: pkg-config ✔, nasm ✔ Required: wxmac ✔, osxfuse ✔

And now occurs the issue:

n102:~ hendrikwindel$ brew install truecrypt ==> Downloading ftp://ftp.archlinux.org/other/tc/truecrypt-7.1a.tar.gz Already downloaded: /Library/Caches/Homebrew/truecrypt-7.1a.tar.gz ==> Patching patching file Main/Application.cpp Hunk #1 succeeded at 36 with fuzz 2. patching file Main/CommandLineInterface.cpp patching file Main/Forms/Forms.cpp Hunk #1 succeeded at 263 with fuzz 2.

I have no idea what could be wrong. There is only a short prehistory. But I think it isn't connected with this issue.

  • brew info truecrypt => Error: No available formula for truecrypt Apr 1, 2014 at 16:18
  • That means what? I cannot follow you...

  • It means that I can't reproduce the error and it seems that truecrypt is not on brew... (but I might made a mistake). Try to run brew update then brew info truecrypt Apr 1, 2014 at 16:43
  • Thats the prehistory

  • Yes, I know, I'm the one who answer you. I told you to do that because brew pull truecrypt worked. It seems that truecrypt is no longueur on brew so I can't reproduce the error and that's might be the reason your installation is not working. Apr 2, 2014 at 6:39

Bad News

The Truecrypt Formula on Homebrew has been removed due to bugs, and probably uncertainty in the community regarding truecrypt's safety.

There also used to be a homebrew cask which was removed due to installation bugs. However, it was also moved to homebrew-unofficial and scheduled for removal.

For more information about the 3rd party audit, and why Truecrypt is still safe to use, please see the links mentioned here.

Good News

I have created a Homebrew Tap for Truecrypt 7.1a which fixes the installation problem, and works on OS X 10.10 Yosemite!


First, make sure you have installed homebrew-cask if you haven't yet:

brew install caskroom/cask/brew-cask

Then, run the following in your command-line:

brew tap trinitronx/homebrew-truecrypt


Note: For info run:

brew cask info truecrypt

Once the tap is installed, you can install truecrypt!

brew cask install truecrypt
