Yesterday, I upgraded my MacBook OS to Yosemite 10.10. But when I reinstall Truecrypt(For some reasons, recommend Truecrypt 7.1a version), something get error.

TrueCrypt-Error

Guess the OS X version numbers. Truecrypt thinks 10.10 is < 10.4 (the minimum Truecrypt requires), and the installer will block it’s installation on Yosemite. So you’ll be able to install it again on 10.40…or maybe, possibly 10.11 or later.

In the end, I found two solutions:

The first:

  • Open the .dmg
  • You’ll find the .mpkg. Right*click and “Show Package Contents”
  • Open Contents Dir
  • Open Packages Dir
  • Install each of the 4 packages in this order: OSXFUSECore.pkg, OSXFUSEMacFUSE.pkg, MacFUSE.pkg, TrueCrypt.pkg (It is possible MacFUSE.pkg will install the two before it, but we ran each to play it safe.).

That’s it; it’s Truecrypt has been working fine for us using this method.

The second:

  • Open the .dmg

  • You’ll find the .mpkg. Right click and “Show Package Contents”

  • Open Contents Dir

  • Edit Contents/distribution.dist using Text Editor

  • You’ll find the code as below

    function pm_install_check() {
  if(!(system.version.ProductVersion >= '10.4.0')) {
    my.result.title = 'Error';
    my.result.message = 'TrueCrypt requires Mac OS X 10.4 or later.';
    my.result.type = 'Fatal';
    return false;
  }
  return true;
}

  • change it as follow:

    function pm_install_check() {
  return true;
}

Now, you can install .mpkg without error.
