The SimCity Website has word that Maxis plans to launch the OS X edition of SimCity on June 11, saying the this will be offered as a single purchase with the Windows edition, and confirming this will support cross platform play (thanks Polygon). They have a full FAQ, and this overview: "Good news, Mac Mayors – today we can officially confirm the release date for the Mac version of SimCity is June 11, 2013. If you already own SimCity on PC, you will also receive the Mac version at no additional cost (and vice versa). If you don’t already own SimCity on PC and just wish to purchase the Mac version, you will be able to pre-purchase your copy on Origin starting April 10th."
