yes. It doesn't works with your hardware :)
Strange that it worked on mine:
 - 4 years old Mac Pro
 - lion

what you can do is go to #createContext: method and play with various
options for
GL pixel format.

attribs := CGLPixelFormatAttributes for:  {
		KCGLPFADisplayMask -> self mainDisplayMask.
		KCGLPFAColorSize -> 24.
		KCGLPFAAlphaSize -> 8.
		"	KCGLRPAccelerated."
		KCGLPFASamples -> 8.

you should be able to create a context.. but of course it is a big
question if with your format my demo will still run , because it wants
some extensions :)

Best regards,
