title: How do I trigger sound alert in OSX using Cocoa?
body: <p>When Finder finishes copying of files then it triggers a sound alert. How can I do that from my app?</p>
  
  <p>Please note that it is not the same as simply playing a sound. I am from Windows background so I am assuming that OSX allows users to configure notification sound from some central location. So, if the user chooses a different sound for an event then that API should play that new sound. This way I can make my app gel into the system and it will be able to alert the user using sound which the user is familiar with.</p>
