Blizzard will have a new World of Warcraft: Mists of Pandaria beta patch out tonight which opens Townlong Steppes for testing. Mac users should definitely read about current issues in this upcoming build.

As usual, Blizzplanet will have exploration videos of Townlong Steppes. Check us out tomorrow evening.

We have a new build of the World of Warcraft: Mists of Pandaria beta client almost ready to push live, and it will come up later today. This new build includes a new zone (Townlong Steppes), new quests, and new scenarios.

Please be aware that players testing on 64-bit versions of a Mac OS will be unable to play during this build. There is an issue in this build with Mac-64, and we didn’t want that issue to delay testing for the majority of players.

We expect that we will release the next build, which will include a fix for the Mac-64 issue, later this week.

Thank you for your feedback and continued testing of Mists of Pandaria. — source
