A friend of mine was working on a cross platform OpenGL project and wanted to use some OpenGL extension that was originally proposed by a couple of people from Apple and somebody at Nvidia.

You would assume that having proposed it, Apple would have implemented it. Nope. Windows only.

Apple advertises their support for OpenGL 4 in Mac OS 10.9, but they're only up to 4.1. That's the version of the spec from 2010. No tessellation or compute shaders, among other things that were added in 4.2, 4.3, or 4.4. In particular, 4.3 would be a big step because of parity with OpenGL ES 3.

Tessellation shaders were a part of GL 4.0. See https://developer.apple.com/graphicsimaging/opengl/capabilit...

Ah, you're right. Still, compute shaders are a pretty big deal to be missing, especially for offloading calculations like particle systems and realtime global illumination to the GPU.

10.10 announcements should be starting up in not too long, so maybe we'll see improvements.
