Guild Wars 2 to guide Mac November 14, 2012

Gw2 gold will probably be available for Mac inside a beta version to anyone who purchases Guild Wars 2. The Mac beta version of Guild Wars 2 are still being optimised and, unlike other betas, is attached to the live servers allowing everyone to learn together on Mac and Windows based computers. Users will be able to access the Mac beta client throughout the Gw2 gold account management website after activating their game code.
