title: Cannot quit iOS Simulator
body: <p>Am new to Mac using Mavericks. I double clicked a js file with some node code and to my surprise the iOS Simulator pops up. I googled and found:
  To quit iOS Simulator, choose iOS Simulator > Quit iOS Simulator</p>
  
  <p>I have clicked on everything I can think of but there is nothing resembling this.
  Is there a way to kill the process using the terminal and some command lines?</p>
