from http://developer.apple.com/graphicsimaging/opengl/capabilities/GLInfo_1072_Core.html appears that current OSX 10.7.2 core OpenGL support is still limited at 3.20 with GLSL 1.50
among other data are the available ARB_ extensions.
I was wondering if these were the minimum guaranteed to be present extensions, or if you really have only these four, namely:
ARB_instanced_arrays
ARB_occlusion_query2
ARB_shader_bit_encoding
ARB_timer_query
Im currently developing a portable application that should run on OSX and uses ARB_separate_shader_objects, does it mean it will definitely not run on OSX 10.7.2?
Those, plus the extensions that are part of the legacy profile, are the only extensions currently available with Apple’s drivers for the drivers/graphics cards listed on those pages.
