title: How to manually create icns files using iconutil?
body: <p>When I'm validating my app I get this error: </p>
  
  <blockquote>
    <p>the application bundle does not contain an icon in ICNS format, containing both a <code>512x512</code> and a <code>512x512@2x</code> image.</p>
  </blockquote>
  
  <p>I use to make the icns icons with <a href="http://www.img2icnsapp.com/" rel="noreferrer">Img2icns</a> app and until today it always worked properly. But now I'm getting that error and there's no way to make it work. I tried to put two PNG files together (<code>512x512</code> and <code>1024x1024</code>) in <a href="http://www.img2icnsapp.com/" rel="noreferrer">Img2icns</a> but I always get that error. I also tried to follow the instructions in Apple's OS X Human Interface Guideline but when I try to make the icon sets I get this terminal error:</p>
  
  <blockquote>
    <p>-bash: syntax error near unexpected token 'newline'</p>
  </blockquote>
  
  <p>I am not very good with terminal commands so maybe I'm doing something wrong. I wrote:</p>
  
  <pre><code>iconutil -c icns &lt;/Users/myname/SDK Mac Apps/MyApp/grafica/icon.iconset&gt;
  </code></pre>
  
  <p>If anyone could help it would be very much appreciated. Thanks, Massy.</p>
