title: Maximum PID on osx
body: <p>I found <a href="https://stackoverflow.com/questions/6294133/maximum-pid-in-linux/6294210#6294210">this question</a> about what's the maximum PID for Linux and my question is exactly the same for OSX :</p>
  
  <p>OSX doesn't seem to have the <code>/proc/sys/kernel/pid_max</code> file containing this value on Linux.</p>
  
  <p><strong>Is there an equivalent file or an other way to find out what is the range of PIDs on an OSX system?</strong></p>
