title: Error when enabling auto login of macOS app using a helper
body: <p>I'm trying to have my app auto launch on login following Tim's tutorial: <a href="http://blog.timschroeder.net/2012/07/03/the-launch-at-login-sandbox-project/">http://blog.timschroeder.net/2012/07/03/the-launch-at-login-sandbox-project/</a></p>
  
  <p>I followed the instructions to the letter but I'm getting an error when I re-login to my computer as follows: </p>
  
  <pre><code>Jan 10 12:55:01 pc61 com.apple.xpc.launchd[1] (com.myApp.macgap.helper[25725]): Could not resolve CFBundleIdentifier specified by service: -10814: com.myApp.macgap.helper
  Jan 10 12:55:01 pc61 com.apple.xpc.launchd[1] (com.myApp.macgap.helper): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.
  </code></pre>
  
  <p>To outline: </p>
  
  <ul>
  <li>I have my main app called "myApp" (ID: com.myApp.macgap )</li>
  <li>In that app I have a helper app with ID: com.myApp.macgap.helper</li>
  <li>When you launch the main app and go to preferences, you have an option to enable auto login (to fit to the Apple compliance rules) </li>
  <li>I log out of my computer, log back in and look at the console to see what's going on (that's how I get the code above)</li>
  </ul>
  
  <p>Another point worth mentioning, is when I do "Show package content" on the app and double click the helper app, it does launch the main app...</p>
