For some reason the Mac version gives me an "application can't be opened" error.
Hmm this is concerning. The few mac players I've had so far seemed to have no problem, but I couldn't test it myself since I don't own a mac.
I've googled it a bit and people seem to have the same issue here, I think you might have a solution in there. I think the problem comes from the fact that I'm zipping the build from a Windows OS. Let me know if a solution in this thread worked for you!
