Does it say anything?

No, it just shows a box on my dock that doesn't do anything

A box on your dock? Sorry don't quite know what a Dock is.

Mac OS X dock

Oh, sorry, never seen a Mac in real life.

I presume thats the Mac equivalent of the Windows Taskbar? (Little bar that goes along bottom with start menu and icons for programs in use)

Are you by any chance in the GMOD 13 beta? If you just bought it and downloaded it (and updated fully) you shouldn't be. But the beta doesn't work in Mac yet.

Other than that I'm not sure, you could try a reinstall, or verifying the integrity of the game to see if all files are present and correct.

Counter-Strike: Source
Portal 2 (for only $5 during one of the flash sales!  )
Dungeon Defenders (plus a couple of the DLC's. I only got a $20 Steam card, if only I had gotten a $50 one, I would have gotten the full pack for only $14. )
