I'm following this website's instruction so I can run Linux gui app on my mac:
I've downloaded Kitematic (v0.17.7) and docker toolbox (v19.03.1) from github.
However, when I enter
docker pull kartoza/qgis-desktop on the terminal, I get the following error:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Does anyone know what could be wrong?
