Mac version not working AND jar crashes when sound is on

First of all, the mac app is not working at all. Simply says that this is not a valid application.
I can get it to work by downloading the linux version and running that one, but if i have sounds enabled the game crashes.
I'm running OS X 10.10 and Java 8 btw.
