title: I get an error that I can not connect to the macos :: daemon daemon
body: <p>I am using a docker in a mac mojave.</p>
  
  <p>I normally use the docker, but suddenly I get an error today.</p>
  
  <p>I downloaded the docker from the official homepage of the docker rather than the brew, but when I input the docker command, the following error </p>
  
  <p><strong>error</strong></p>
  
  <blockquote>
    <p>Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is
    the docker daemon running?.</p>
  </blockquote>
  
  <p><strong>Dozer version</strong></p>
  
  <blockquote>
    <p>18.06.1-ce, build e68fc7a</p>
  </blockquote>
  
  <p>I looked at the article asking me to install docker-machine and virtualbox to solve my problem.</p>
  
  <p>However, I have not had any problems using the Docker until now, but I am now wondering about this error.</p>
  
  <p>Of course, I have been using the docker for a few days and have been doing tutorials such as simply loading images.</p>
