title: PyInstaller icon option doesn't work on Mac
body: <p>I ran the following command on my mac and created an .app file.</p>
  
  <pre><code>pyinstaller --icon icon.icns --noconsole -n testApp main.py
  </code></pre>
  
  <p>However, the generated .app file does not show the icon.</p>

  <p>icon.icns is specified as an icon file in info.plist.</p>

  <p>The Content/Resouces folder contains icon.icns.</p>

  <p>When I run the .app file, I see an icon on the Dock.</p>
  
  <p>However, the icon is not reflected in the .app file itself. Why is this?</p>
