title: The 'Always Allow' button not showed when accessing keychain
body: <p>While I was archiving iOS package through XCode, it told me that it needed to access system keychain. So, I put in my account and password then pushed the 'Allow' button, But soon it asked me again. </p>
  
  <p>I know the 'Always Allow' button is right choice, but that choice did not appear at the place it should be! </p>

  The image shows the information in Chinese. Only buttons of 'Deny' and 'Allow' appear.</p>
  
  <p>Maybe I have changed the system configuration in the past, but I can not remember. How to solve this problem?</p>
