title: Can't get my Mac App signed for testing receipt validation
body: <p>I have my "Mac Developer: ..." certificate installed and it is valid.
  I have the Apple Worldwide Developer Relations intermediate ceritficate as well.
  I also have a "3rd Party Mac Developer Application" distribution certificate.</p>
  
  <p>In my build settings I have chosen my "Mac Developer: ..." identity for code-signing. 
  When I built the first time, codesign asked for permission to sign my app and I clicked Always Allow.</p>
  
  <p>Then I did a "Show in Finder.." to see the Product of the build. I found my .app and double clicked it. However, this is what is shown in the system Console:</p>
  
  <pre><code>10/13/11 8:40:44.531 PM storeagent: Unsigned app (/Users/kenny/Library/Developer/Xcode/DerivedData/MyAppName-gabpxiaypxtnikelsyzjwkperixq/Build/Products/Debug/MyAppName.app).
  </code></pre>
  
  <p>I'm not running the app from Xcode, I just opened the Console app and then double-clicked the app in my build directory.</p>
  
  <p>Why is my app still unsigned? What am I missing?</p>
