TrueCrypt for OSX Yosemite

I’ve had some crashes with TrueCrypt on OSX Yosemite. Then I found this post and decided to build my own TrueCrypt.app from source. The advantages should be use of 64bit hardware support hardware-accelerated AES encryption and – as I hope – more stable behaviour when making copies of large files to my exFat formatted TrueCrypt drive.

It seems like a very difficult thing to do but once you get there it’s pretty simple. Here is a walkthrough:

  1. Install Xcode from the App Store
  2. Start terminal to install the command line tool for Xcode with
    xcode-select –install
  3. Install MacPorts
  4. Go to terminal and get some build dependencies for MacPorts
    sudo port install wxWidgets-3.0 osxfuse nasm wget pkgconfig
  5. Select wxWidgets with:
    sudo port select wxWidgets wxWidgets-3.0
  6. Download the patched TrueCrypt source code from Github
  7. Find the source directory using ls and cd commands For me it was:
    cd Downloads/TrueCrypt-master
  8. Build:
    make -j4
  9. Now you can close Terminal
  10. Use finder to drag the Truecrypt.app from Downloads/TrueCrypt-master/Main to your applications folder.

Works like a charm. Two sidetones:

  1. I’m not sure you’ll need step 1 to 5 since the code from Github has already been patched. Need to test it next time
  2. The GUI is said to be buggy so it’s best to use command line all the way. Then you need to replace step 8 with:
    make -j4 NOGUI=1
