title: Launch Octave with GUI
body: <p>I downloaded octave version 4.2.1 as instructed here <a href="http://wiki.octave.org/Octave_for_macOS" rel="nofollow noreferrer">http://wiki.octave.org/Octave_for_macOS</a>, and I am able to run Octave from the terminal. However, I cannot launch Octave using GUI. When I add the command <code>--force-gui</code>, nothing happens. </p>
  
  <p>I have tried <code>brew reinstall octave --with-qt --with-fltk --with-gui
  </code>, which does not help. </p>
  
  <p>Any ideas?</p>
  
  <p>Thank you</p>
