I'm following this website's instruction so I can run Linux gui app on my mac:
https://kartoza.com/en/blog/how-to-run-a-linux-gui-application-on-osx-using-docker/
I've downloaded Kitematic (v0.17.7) and docker toolbox (v19.03.1) from github.
https://github.com/docker/kitematic/releases
https://github.com/docker/toolbox/releases
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?
