You can check OpenGL configuration on OSX here. https://developer.apple.com/graphicsimaging/opengl/capabilities/
 If you are on 10.8 it should support 3.2 but maybe the deprecation of Texture2D  makes it unavailable in a GL 3 Core context.

Thanks, that clears things up, seems my hardware is OpenGL 2.1 and GLSL 1.20. Although my 2nd edition "OpenGL Shading Language" has texture2D listed as being supported in 2.0.  I haven't done much with shaders, but they seem to be supported in 2.0 so I'm going to try and back-port the demo to OpenGL 2.0
