-I had issues installing Docker so Looked up how to do it via shell [I used the *Brew package installer], I added a more in depth reference below.
- Update Brew brew update
- Install doker brew install docker
- Install docker machine brew install docker-machine
- Install virtualbox brew install --cask virtualbox
....You might run into issues running the 4th command
- You will have to allow software installation from Oracle blah-blah-blah in your System Preference. Chances are your sytem will pop out that information for you and then do a restart.
**Everything about docker and it's environment is set up already
