Mac client, new download, official server, games becomes unresponsive on load

I have been trying to get this to work since I purchased the game. I click on the Official server (I have tried several), the game starts to load I can even get as far as “Waiting on Server” then it just sits there with the spinning beach ball. No matter how long I wait it will not progress beyond that point. I have verified the cache, reinstalled the game, etc. without avail. Suggestions ?
