title: 3rd Party Mac Developer doesn't match any valid, non-expired private key pairs?
body: <p>I just cloned <a href="https://github.com/kgn/Spectttator" rel="nofollow">this repo</a> from github and would like to have a play with it. However, in XCode, I keep getting the following error:</p>
  
  <p><code>The identity '3rd Party Mac Developer Application' doesn't match any valid, non-expired certificate/private key pair in your keychains</code></p>
  
  <p>It's worth noting that in my Build Settings, I've set the <em>Code Signing Identity</em> property to <strong>Don't Code Sign</strong>, but I'm still getting this error.</p>
  
  <p>Has anyone ever encountered this, and if so, what did you do to fix it?</p>
  
  <p>Thanks!</p>
