title: Is OpenGL on macOS deprecated?
body: <p>I've started to get a little involved with OpenGL, but I get warnings all the time!</p>
  
  <p>Why is, for example, <code>glutInit(&amp;argc, arg);</code> deprecated in macOS 10.9?
  ('glutInit' is deprecated: first deprecated in macOS 10.9 - OpenGL API deprecated.)</p>
  
  <p>Is there any way to <strong>Update</strong> OpenGl?</p>
