Ok, so after 5 years I install Windows XP on my new iMac i7 (XP SP3) and I install Counterstrike Source. Now previously, I returned a mac that I got to run CS:S with VMWARE fusion, but now I running boot camp. My question is, how the hell do I play a game? Steam keeps redirecting me to the game page to BUY the game. I was playing Counterstrike just fine on my iMac that I returned (although it was glitchy since I wasn't on Bootcamp) but I don't know how to even play single player Half Life 2. Edit: Sorted it out with Steam. Thanks for the replies.
