So how about a little web searching? I'll get started for you...
For example:
http://developer.apple.com/macosx/architecture/index.html
Which led to this:
http://developer.apple.com/graphicsimaging/opengl/
The initial search also indicated some third party graphics libraries for OS X, for example, http://www.macobserver.com/article/2007/08/20.13.shtml
Good luck!
