Going to mark this as done for now - The next patch that comes out should resolve this problem. If not, let us know and we'll reopen it to investigate further.

Thanks. I can see a number of problems occurring in the log there. However they are very vague and do not appear to be caused by our own code. I suspect some kind of hardware incompatibility between your hardware and the 3D engine we use (Unity).

Unfortunately I cannot provide any immediate steps to resolve this for you - It works on all the OS X hardware we have here. It may be resolved in a patch or two, however I understand that you may not want to wait that long and so I would suggest that you request a refund through Steam to get your money back.

I'm really sorry I cannot assist you immediately. We'll keep looking into the problem regardless. :(

Could you please upload a new Player.log file for review? Thanks.

Can you please follow this guide on how to submit a bug ticket to provide us with more information? Thanks.

Do you use headphones by any chance? We've had reports in the past where if the headphones or unplugged the game will start working.

Can you please provide details on your hardware and OS platform?

Is it possible you can upgrade to OSX 10.12 "Sierra"? Or is there a reason you need to be on Capitan?
