Mad Mac is a utility that helps you get your macintosh computer back up and running. It will guide you through the steps to take to get your mac working again. Mad Mac is also a troubleshooting guide. The advantage this program has over repair guides that run on your macintosh. Is that when your computer has startup problems you cant get to your repair guide software on your mac because you cant even get it to start up. You also don't have to carry around all of your big heavy Mac troubleshooting books anymore if you buy this program that is only $10. My program is also very small and barely takes up any space on your palm at all. This program has been tested on and is compatable with the Palm III, Palm IIIc, Visor Deluxe and the Visor Prism. It can also be run from a flash module on any Visor.
