Steam allows games to be installed on multiple computers as long as they're not both played at the same time. I'd like to get my Steam games installed on my laptop and on my desktop (both are Macs.) I have a somewhat slow Internet connection and I'd like to avoid downloading all of the games twice if possible. Is there any way that I can download the Mac versions onto my desktop, then copy the game files from my desktop to my laptop and make Steam on my laptop recognize that I'm entitled to play them? If so, how?
