title: Where is the iconset command-line tool 'iconutil' located?
body: <p>I have XCode 4.2 and need to submit a Mac app to App Store. I've tried all kinds of suggested methods to get the multi-resolution icons in there, so you don't need to inform me on that.</p>
  
  <p>The remaining method is to use <code>iconutil</code>. I've searched in Spotlight, searched my Mac's harddisk in Finder, two later XCode <code>.dmg</code> images, <code>sudo find</code> in Terminal, and looked for paths on the web. The XCode 4.4.1 <code>.dmg</code> had <code>Iconutil.strings</code> and <code>Iconutil.xcspecs</code>, but that's as far as I've come.</p>
  
  <p>Is there a package I can download to get this command or tool, so I can convert the <code>.iconset</code>? If there is a setting I can change in XCode to make it allow the old <code>.icns</code> files (before <code>1024x1024</code> and <code>512x512@2x</code>), that would be a solution that I could accept temporarily. I have OS 10.6.8.</p>
  
  <p><strong>EDIT</strong><br>
  I would accept an answer that confirms whether the command is there in 10.6.8 and where it is. I would accept an answer that links to a valid <code>.icns</code> file with <code>512x512</code> and <code>512x512@2x</code> (preferably uncompressed <code>.png</code> inside) that has been approved by App Store validation recently.</p>
