OS X Engineers don't care about these benchmarks. They never have. Having OpenGL 4.1 and OpenCL 1.2 optimized throughout their entire OS is what they care about.
Linux can get its pants soiled about these meaningless benchmarks, while having crippled accelerated desktops raving about OpenGL 2.1 future compliance with OpenGL 3.1 in the near future all it wants.
One would think having a fully acceleratd DE whether GNOME or KDE, etc., at OpenGL 3.3, never mind 4.x would be a far greater goal than these pointless benchmarks.
