title: Mac Terminal: Error writing
body: <p>I'm executing this line in Terminal:</p>
  
  <pre><code>sudo nano /Applications/Utilities/Boot\ Camp\ Assistant.app/Contents/Info.plist
  </code></pre>
  
  <p>The file is opened correctly, I'm changing the file, press Ctrl+X, then Y, then Enter. That pops out:</p>
  
  <pre><code>[ Error writing /Applications/Utilities/Boot Camp Assistant.app/Contents/Info. ]
  </code></pre>
  
  <p>What should I do to save my changes?</p>
