title: Docker CE on Mac OSX hanging on startup
body: <p>I had docker working and then I went and upgraded the version by downloading the latest Docker CE dmg from docker.com and installing over the old version. Since then I have been unable to get the Docker app to start. </p>
  
  <p>Double-clicking it would make a spinning beach ball of death appear when hovering over the tray area where the docker icon should open. After a few seconds the activity monitor would list Docker as "not responding". </p>
  
  <p>Attempting to start the app via the command line as sudo gives the following error:</p>
  
  <p><code>/Applications/Docker.app/Contents/MacOS: sudo ./Docker
  json error: Error Domain=NSCocoaErrorDomain Code=3840 "No value." UserInfo={NSDebugDescription=No value.}
  kern.hv_support: 1</code></p>
  
  <p>And the process still hangs.</p>
  
  <p>Mac OS Info</p>
  
  <pre><code>El Capitan
  10.11.6 (15G1217)
  </code></pre>
  
  <p>Latest Docker version at the time:</p>
  
  <pre><code>Version 17.03.0-ce-mac2 (15654)
  Channel: stable
  </code></pre>
  
  <p>I've tried uninstalling and reinstalling the docker app. I could not use a Factory Reset on Docker since it never fully started. I have tried uninstalling, rebooting, and reinstalling. I have tried to removing the <code>~/Library/Containers/com.docker*</code> directories.  I've removed all of the docker links in <code>/usr/local/bin</code>. I've tried going back to older versions of Docker such as 1.12.6.14937. I've tried the edge version of the latest Docker.</p>
