Download the package from https://truecrypt.ch/downloads/ or https://www.truecrypt71a.com/downloads/.
Find downloaded package using Finder in your HDD/Users/username/Downloads folder and will look like TrueCrypt 7.1a Mac OS X.dmg.
Open file location in Finder and open or double click on TrueCrypt 7.1a Mac OS X.dmg. This will mount Truecrypt 7.1a and will have Truecrypt 7.1a.mpkg in it.
Drag the package TrueCrypt 7.1a.mpkg and drop in your Downloads folder.

Now go to your Downloads location, find the file TrueCrypt 7.1a.mpkg, right click and select Show Package Contents. Find the file Contents/distribution.dist and open with your favourite editor.
You need to find the line with '10.4' and change it to '10.14' as per below code.
function pm_install_check() {
# if(!(system.version.ProductVersion >= '10.4')) {
if(!(system.version.ProductVersion >= '10.14')) {
my.result.title = 'Error';
my.result.message = 'TrueCrypt requires Mac OS X 10.4 or later.';
my.result.type = 'Fatal';
return false;
}
return true;
}
Save this document, quit editor and go back to the package.
Now open TrueCrypt 7.1a.mpkg and follow the installer and at least it worked for me.
