The Mac Special Edition was made possible using TransGaming's Cider Portability Engine, which acts as a "wrapper" around the Game Client, enabling it to run seamlessly on Intel-based Macs running Mac OS X. TransGaming, Inc., is a leader in the development of unique software portability products that facilitate the deployment of games across multiple platforms. TransGaming's portability technologies significantly reduce the time-to-market for and costs associated with multi-platform game releases. The Mac version was officially released on January 7, 2009.
