No Compatible Shaders for Mac

[Assorted-Nuggets]

The shaders that you have written should also have an osx compatible version as well.

This could be quite easily ported using code from BennyQBDs 3DEngineCpp (see shader.cpp line 66 following)

Also you should remember that OS X set OpenGL version to 2.2 by default. However you can switch to core profile mode and get the best OpenGL version available for your graphics card(you can also update the driver).
