Sims Medieval

[Daddy Cool]

Hey guys, does anyone know how to get the Key for Sims Medieval? I bought it today and, dumb as i am, its not for Mac OS... So i want to get the game files from a friend and use my own Key to activate the game. Yes, there is a Mac Version of this game but not available on Steam....Since i cannot download Windows games on my Mac OS Steam this is pretty *******.. Anyway. Does anyone know how to find out my Key for this game? Of course, I found the button "your key for sims" (or kind of this) but it doesnt show me any key... Its sad to have so much trouble installing a game... In my opinion Steam should automatically block payments for games not available on ones OS... Hope someone can help me. Cheers
