ArenaNet has just announced that Guild Wars 2 is now available on Mac as well.
Before release the developers had promised support for Apple’s Mac OS X and now have delivered on that promise. Anyone with a copy of Guild Wars 2 will have access to both clients.
ArenaNet confirmed that there are no differences in features between the two clients and both will have the same access to the server.
It would be personally interest me very much if ArenaNet released the amount of downloads of Mac vs PC.
For more information on the Mac client, you can head on over to the Mac FAQ.
