There’s a line in the patch notes that most people probably didn’t pay much attention to:
Rewrote OpenGL implementation for Intel Macs with Mac OS X 10.5.7 or later.
It’s great that Blizzard was thinking about us Mac users, but unfortunately there are a lot of bugs with their new implementation.
One of the worst bugs is that if you hit the Command key in combination with any movement keys, it will turn on auto-run. Since I use Command-Click to right click on my laptop, this results in a lot of crazy spinning and running when I don’t expect it to happen. I’m surprised I didn’t fall off any cliffs during my run through Frozen Halls yesterday.
Other issues have been reported with the trackpad, desktop gamma, and camera lag.
Blizzard’s Mac technical support is working on a patch to be released “within a week’s time” to handle some of the issues, but for now there is a workaround – use the old OpenGL implementation. Here’s how you do it:
1) Close the WoW application
2) Navigate to your main World of Warcraft folder
3) Open the config.wtf file in your WTF folder using TextEdit
4) Add the following line to the bottom of the file: SET gxapi “OpenGL”
5) Save and Close
6) Restart WoW
