It should run equally well on Mac or Windows (or others). You should just be able to download it, double-click on it, and have it run (after the usual java startup lag)
For the paranoid, source code is also available. Please note: this is *my* code, you do not have the right to steal it and go put it up somewhere else calling it your own. You are welcome to use and tweak it for your own puposes, however.

First, select "coolmod.zip" as your "Modfile to add".
Then, change the name of the New jar file, to be coolmine.jar.

Time to test it out!
This time, use the "Copy new to minecraft.jar" button, to test the combined result. Then run minecraft, to test it out. If you like it.. great! Keep it. Otherwise, you can click on the "Unmodded Copy" button to Restore the pristine minecraft.jar file,and try new combinations.
