Guild Wars 2 is going to support Mac OS X
NCsoft and ArenaNet have announced today that Guild Wars 2 will also be supporting Mac OS X. The game will be available for Mac in a beta version for anyone who bought the game.
The Guild Wars 2 Mac version is still optimizing and is connected to the current game servers, which allows PC and Mac users play together. To achieve this, ArenaNet has partnered with TransGaming, whose revolutionary Cider technology allows a dynamic transition between operating environments. This means that future updates to the game will also be available for Windows and Mac at the same time.
