So what does it means?
Short answer: i have no idea
Long answer: i have nooooooooooooooooooooooooooooo idea :D
But the good news is apple engineers are giving hands for this OpenGL update. Kinda surprised since lots of complaint in previous update caused by the absence of apples mind on the update. Remember 10.6.0? That was the darkest day of apple CG. But Im seeing bright future on this one.
Oh yes... and OpenGL 3.0 is also a massive updates. Those pain you got to enable the extensions, is predicted to be gone *crossfinger*
Good luck and Godspeed, Apple and Khronos
