Fix Docker Won't Start Error On macOS

I recently updated Docker on my Mac and began getting errors that it was not able to start the daemon:

com.docker.osx.hyperkit.linux failed to start
Exit code 1

I tried uninstalling and re-installing, to no avail. After doing a little searching, I came across an issue on the Docker Github repo with some tips.

The short fix is:

rm ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2

Hope this helps someone.
