With the availability of Steam client for Mac, Steam also introduces Steam Play. SteamPlay allows players and gamers who have already purchased compatible products in the Windows version to re-download the Mac versions at no cost, and vice-versa. Note that not all games are in Steam Play list though, and some game titles does require user to purchase Windows and Mac versions separately to gain the cross-platform functionality.

The Steam Cloud is Windows and Mac cross-platform compatible, so does multi-player games, allowing Windows and Mac players to play with each other. Portal 2, due by the end of 2010, will be simultaneously released on both the Windows and Mac versions of Steam.
