title: How do I upgrade my OpenGL from 2.1 to 3.3 on Mac OSX?
body: <p>I am trying to program OpenGL 3 in C on my Macbook Pro.</p>
  
  <p>My graphics card is <code>NVIDIA GeForce 320M 256 MB</code>, but I have OpenGL 2.1 According to <a href="http://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units" rel="noreferrer">wikipedia</a>, I should be able to use OpenGL 3.3:</p>

  <p>However, when I run <code>glxinfo | grep -i opengl</code>, I get <code>OpenGL version string: 2.1 NVIDIA-8.24.16 310.90.9.05f01</code>.<br>
  How do I go about upgrading it? I am running Mavericks.</p>
