title: SMJobBless failed with CFErrorDomainLaunchd Code 9
body: <p>Does anybody know what does that error code mean?
  I get SMJobBless error with this return code value. </p>
  
  <pre><code>Failed to bless helper: Error Domain=CFErrorDomainLaunchd Code=9 "The operation couldn’t be completed. (CFErrorDomainLaunchd error 9.)"
  </code></pre>
  
  <p>I googled, looked answers in blogs posts, in Apple Docs, here there and couldn't find the answer what is this and how to fix it. People say(on some support forum that reinstalling OS X helped to them).</p>
  
  <p>It has happened on my ongoing project already couple of weeks ago, and the only thing which helped me to fix it, was changing name of my helper tool. Now it happened again. </p>
  
  <p>Same time my code is working on other computers, only my workstation is affected by this issue.</p>
  
  <p><strong>Update:</strong> 
  After renaming, it works again. Now I have two helper tool bundle identifiers "banned" on my system :-(</p>
  
  <p><strong>Update 2:</strong> 
  It happens on other computers as well :-(</p>
