The compatibility profile for OpenGL 3.2 is not available on OSX. OSX 10.8 supports OpenGL 2.1 and OpenGL 3.2 core profile. The graphics hardware of the MacBook Pro Retina includes the integraded Intel Graphics HD 4000 GPU (part of the Ivy Bridge Core i7 processor) and a discrete NVIDIA GeForce GT 650M with 1GB of dedicated memory. The MacBook Pro Retina 15-inch offers three kinds of OpenGL renderers: two hardware renderers and one software renderer (first time I play with an OpenGL software renderer). I did it for Linux (see Linux: Mesa, Gallium3D, Nouveau…) and now I do it for OSX. One of the first things I do when I arrive on a new OS is to look at the OpenGL support and extensions. I code with this laptop for some weeks now and I thought it was time to write a bit about the first contact with OpenGL under OSX from the point of view of a Windows developer… I could enter in Mac’s world thanks to a MacBook Pro (with a 15-inch Retina display). This lib is cross-platform and supports Windows, Linux and now OS X. These last months I worked (and I still work) on my new 3d lib that will be used in all my new tools.
