  <p>What macro to use to identify when compiling on OSX 10.9 specifically. As opposed to other versions of OSX like 10.8, Snow Lion, Lion, Leopard, Leotard, Puma (made that one up), or Harrison Ford.</p>
  
  <ul>
  <li><code>__APPLE__</code> only gives a boolean, and isn't enough information about this.</li>
  <li><code>__APPLE_CC__</code> gives a version number of sorts, but that seems to be about the compiler and no the general OS. </li>
  </ul>
