Я установил Docker (19.03.12) и Docker-Machine через Homebrew на Catalina (10.15.6) Когда я пытаюсь выполнить простую команду, такую как docker images я получаю сообщение

Не удается подключиться к демону Docker в unix:///var/run/docker.sock. Запущен ли демон docker?

Это команды, которые я использовал для подтверждения того, что служба Docker-machine установлена и запущена

     username@hostname ~ % brew install docker docker-compose docker-machine

To have launchd start docker-machine now and restart at login:

Or, if you don't want/need a background service you can just run:
  docker-machine start
