I have no idea why, but that's because I don't use a Mac. Abe said it ran though? I'll check with him. Thanks for the heads up!
It works, but like with all other applications you download form the internet, you need to change the security settings to open it. For those having a hard tie with the Mac version: simply go to System Preferences>Security & Privacy> General and allow the app to run (bottom of the General panel). You need admin permission over the machine
