When there's a version that works with the current version of the OS this program is tough to beat. Unfortunately updates are so few and far between and with absolutely NO communication from the developer, I'm forced to conclude that this is abandonware. If this software works with your current version of OS X, good for you. It really is a great program but with no support. I personally have given up on it. I currently use Tinkertool/Tinkertool System. little more difficult to use since it consists of two applications, but it is regularly updated and costs $5.00 less.
