Under 10.6.4, when I installed the 4.0.1 patch for WoW, the Radeon HD 5770/5870 on the Mac Pro could only select "Low" and "Fair" quality presets. This has been fixed with with 10.6.5. You can now choose "Good," "High," and "Ultra" presets.
Also, if you use manual quality settings, you could only choose up to "High" for Shadow Quality and "Fair" on Liquid Detail. Those are also fixed.
