EA's Origin Game Download Service Now Available For Macs
Electronic Arts' PC download service is no longer exclusively for PC games. Now you can use it download Mac compatible games, as well.
Along with all the requisite features from the PC version of Origin, like cloud saves and social networking options, you will also be able to buy a game once and play it on either operating system. As long as the game is compatible with both Mac and PC platforms, you only have to buy the game once to get both versions.
This isn't the full list, but at the moment EA has confirmed that Dragon Age 2, Batman: Arkham City GOTY Edition, LEGO Harry Potter, and The Sims 3 are all downloadable for Mac.
