title: Cannot connect to X server using docker on OS X - Part II
body: <p>I'm having the same difficulty as the one expressed here: <a href="https://stackoverflow.com/questions/36021958/cannot-connect-to-x-server-using-docker-on-osx">Cannot connect to X server using docker on OSX</a></p>
  
  <p>I'm very confused about the recommended instructions in the above link (I'm a novice on docker), and I'm hoping to get clarification about the following:</p>
  
  <p>1) Do we "touch foo.foam" in a regular OS X terminal or do we touch it in the docker terminal; in my case, following "docker run -ti openfoamplus/of_v30plus_rhel66 /bin/bash"</p>
  
  <p>2) You suggest running paraview (mine is the most recent) just like any other Mac app. So, basically, to double-click on paraview in the Applications folder? But when opening foo.foam via the Open Menu do we just open foo.foam and press the Apply button (it gives errors), or do we actually enter "paraview foo.foam" as per your instruction above? If the latter, then nothing really happens; I can't open anything!</p>
  
  <p>3) If we're supposed to just open foo.foam, what do we do after that? How is docker even aware about any of this? Anyway, when I type paraview from within docker (after foo.foam is opened) I get the same X server error. I wouldn't expect otherwise!</p>
  
  <p>Hopefully, you can provide a more step-by-step set of instructions?</p>
  
  <p>Thanks in advance</p>
