Gave me 20% off and access to the beta (of which I didn't even know about). So I installed the beta and attempted to play it, but it fails to load. I expected it would be able to load, but then tell me I can't play.

Also I am on a Mac.

Any ideas?

Did it say it was compatible with Macs? 

It had the little logo that said PC and Mac on Steam. I'm at their site now to see if its a requirements issue, though I am skeptical...

Yeah their site says for mac.

You should ask for help here or here.

@august: I might try that.

Right now I have all the correct requirements.

Well I don't have a confirmation, but I think the beta might be PC only. I'll wait till the game comes out. Hopefully it'll work for me!
