The H11 viewport works with ATI cards, but had issues with the Nvidia 
cards until OSX 10.7 was released. I believe anti-aliasing is disabled 
because GL_ARB_texture_multisample is unsupported. However, Apple's 
drivers are a bit lower performance than AMD or Nvidia's own drivers, 
though they are improving.

OSX 10.7 also comes with a new OpenGL 3.2 driver, which bumps them from 
the GL2.1 support they have had for years. They chose to implement the 
core profile of 3.2 however, so I'm not sure how that will play out yet.

While H12's GPU acceleration is OpenCL-based, Nvidia cards still hold 
the compute crown over AMD. AMD just hasn't invested quite as much in 
compute yet, though that is also changing with the next-gen AMD 
architecture (2012?).
