Is your MacBook Pro pulling double duty as a gaming machine? EA wants your attention -- it's launching the Mac Alpha of Origin, its digital distribution service. EA is hoping to have the service ready by March, when it will release SimCity for PC and Mac, successively. For now, though, the client is limited -- barring testers from visiting the Origin store, and instead inviting them to launch Bookworm from the client, a puzzle game that's free for users who install the Alpha. The company promises a more complete catalog of EA and partner games when the client officially launches, but didn't drop any specific titles. The service still has some catching up to do, compared to its closest competitor -- but better late than never, right?
