title: Mercurial OS X extension enabling
body: <p>I'm a new mac user and recently installed mercurial on it. Id like to enable a few extensions and am looking for the global hgrc file. </p>
  
  <p>I could'nt find it, so i tried creating "hgrc" files in /etc/mercurial, and ~/.hg .</p>
  
  <p>It still does not work, so I was wondering if someone here had the solved the problem.</p>
  
  <p>Many thanks.</p>
