We do not offer official support for Macintosh, because the games, that are available on Macintosh are not compatible with the Windows version of the game. This is also the reason, why there is no Voobly client for Macintosh is available at this time. This may however change in future, if we add card / board games. In order to play using your Macintosh you can use Oracle's Virtual Box to run a Microsoft operating system on a virtual PC. We however recommend using Parallels Desktop which provides better virtualization support for Macintosh.
