Hey i recently bought a game in the steam sale. I have a mac btw. I bought it and it was sent to my games folder. I tried to install it for you have to before you can play it but it came up on screen " Euro Truck Simulator 2 is not available on your current platform". Anyone help please!
Did you make sure that is was mac compatible before buying it :S Other wise you could try steam customer support
The penguin is Linux, which is a different operating system. Mac compatible games would have an apple as the logo. I'd recommend talking to their Support service and asking for a refund as you weren't aware.
