So new lesson for me today.
Mac computers unlike everyone else… default their openGL implementation to 2.1 unless you specifically set your OpenGL profile exactly right… (current mavericks support is actually for opengl 4.1)
So now im struggling to get my settings perfectly right so that the video card actually switches to OpenGL 4.1 mode.
anyone got any experience with this?
sample code would be a blessing 
thanks
