title: safaridriver not working over ssh
body: <p>I have Jenkins working with OS X slave nodes using selenium over ssh.</p>
  
  <p>I've successfully run the command below to ensure that it is configured correctly.</p>
  
  <pre><code>/usr/bin/safaridriver --enable 
  </code></pre>
  
  <p>When I run a build, I can see the tests starting to run and safaridriver runs, but immediately exits with an error code. At this stage the tests hang.</p>
  
  <p>If I manually run safaridriver with the exact same commandline, then the tests start.</p>
  
  <p>In essense, <code>/usr/bin/safaridriver</code> <strong>errors out when run over ssh</strong>, but doesn't if it is run locally. The same is true no matter what user you run it as.</p>
  
  <p>I'm using <code>High Sierra</code>, <code>Safari 11.1.2</code> and <code>Selenium 3.14</code>.</p>
  
  <p>Anyone run into this problem?</p>
