title: How can I detect if docker for mac is installed?
body: <p>I have some <code>makefiles</code> where most of the stuff should run without configuration. These makefiles have used <code>docker-machine</code> in the past. </p>
  
  <p>Is there a way to detect in <code>bash</code> if the user is using <strong>docker desktop for mac</strong> instead of <strong>docker-machine</strong> ?</p>
