body: <p>How to find the Mac OSX serial number.</p>
  
  <p>Sometimes it is required to get serial number of a mac, and you validate on that.</p>
  
  <p>I needed the same, few years back, when I developed a plugin for <a href="http://www.osirix-viewer.com/" rel="nofollow">OsiriX</a>. I was asked to release it in such a way, only few systems can use that plugin. </p>
  
  <p><em>If we get any better solution than this, that will be quite helpful for all of us.</em></p>
