To make up the OpenGL 4.3 standard, they took a bunch of interesting looking OpenGL extensions, and said 'in order to have a complete OpenGL 4.3 implementation you must implement these extensions without the prefixes'. OpenGL specs are in fact bundles of extensions. Now the fun bit, and why it doesn't matter that they don't support GL 4.2 (or now 4.3). If you're coding for lion, you can guarentee that OpenGL 3.2 is there, and don't need to write multiple render paths like you do otherwise. The reason they did this is because they support this version of OpenGL on all hardware that Lion runs on. No, they released it for GL 3.2 core, which is 1.1 generations behind the now current. When is apple going to get with the program related to 3D graphics? With Lion, they finally released drivers for OpenGL 3.3. Just curious, but you consider someone complaining about problems with the current OpenGL implementation on Mac to be a fanboy? That's a pretty interesting perspective you have there.

My friends who deal with OpenGL on Mac on a nearly daily basis complain of bugs not a lack of features. I am a bit familiar with the process of deciding minimum system requirements.

I worked at a game developer for years, including the Mac development side. Translation I'm an Apple fanboy and frequently string bunches of words together in shallow and lame attempts to defend Apple's retarded and idiotic positions. In other words I think many developers would say Apple is behind in bug fixes not new features. I think most developers would prefer that Apple fix bugs and inconsistencies in the older versions of OpenGL (and video drivers) rather than implement the latest OpenGL. Developers usually want to support anything sold in the last few years. Games don't generally require the latest hardware and software.
