title: Can't modify *.plist LaunchDaemon on OS X
body: <p>I'm trying to (sudo) edit <code>/System/Library/LaunchDaemons/com.apple.nfsd.plist</code>,  because I want to enable NFS shares as described <a href="http://kodi.wiki/view/NFS#NFS_sharing_from_OS_X" rel="nofollow">here</a>. </p>
  
  <p>I am however unable to modify the specific <code>com.apple.nfsd.plist</code> file. SublimeText says it modified the file, but the changes disappear. Nano always mentions the 'Option is not permitted' and I am also unable to force vim to save the specific plist. </p>
  
  <p>I tried modifying the <code>com.apple.nfsd.plist</code> the following ways:</p>
  
  <ul>
  <li><code>sudo su</code>, and then <code>nano/vi com.apple.nfsd.plist</code></li>
  <li><code>sudo vim/nano/vi/subl</code> the specific file, and forcing :wq</li>
  <li>Turning off/restarting the nfsd service via <code>sudo stop nfsd</code></li>
  </ul>
  
  <p>Can't seem to add the extra <code>&lt;string&gt;-N&lt;/string&gt;</code> in the .plist file. 
  What am I overseeing? </p>
  
  <p>Cheers</p>
