Mac Version of Portal 2 Confirmed March 8, 2010

In an unlikely turn of events, Game Informer has has announced Valve is developing a Mac version of Portal 2.  Valve has been a Windows only development house for the majority of their history.  In fact their PC roots are so deep, they were not even for doing console ports of their games, a lot of their early console versions of the original Half-Life were done by outside companies.

However now that Mac versions of Steam have practically been confirmed, a Mac version of Portal 2 seems to be a logical choice.  It seems likely that since Valve is supporting Mac through Steam, more of their future games will be cross platform.

Gabe Newell, the owner of Valve, was a former Microsoft employee before starting Valve Software.
