```
1. Mount the DMG file, and extract the TrueCrypt 7.1a.mpkg
 file from the DMG (just drag it to your Desktop or Downloads folder).
2. Option-Click or two-finger click to on the mpgk file, to bring up the context menu. Select Show package contents.
3. Edit the distribution.dist file. Near the top (it will start at line 12) you’ll find this:


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