Hey, just so you know, theres a fault in the mac package that has the executable set as non runnable. You'll wanna get into the /Contents/Macos and chmod +x the executable. It wouldnt hurt to get it code signed either, as some folks might not know how to get around the unsigned block on the mac. FWIW , your best bet is to package it as a DMG instead of Zip, as ZIP can mangle permissions.
