title: TortoiseHg: No visual diff tools were detected (Mac)
body: <p>I installed <code>meld</code> in my Mac and i want to use this as a visual diff tool in TortoiseHg. (Note that I am using a Mac. )</p>
  <p>I have the following configuration in my <code>.hgrc</code> file. But when I double clicked on a file, I got this &quot;No visual diff tools were detected&quot;. Am I missing something in the file ?</p>
  <p>This is getting a little bit frustrating because I have spent hours on this and still wasn't able to get a solution. Need some help here please .</p>
  <pre><code>[ui]
  merge = /opt/local/bin/meld
  
  [tortoisehg]
  vdiff = /opt/local/bin/meld
  </code></pre>
