How to install Essentia on macOS using an Anaconda environment

[This is a brief note so I don't forget how to do this, and will probably be technically obsolete before long!]

Essentia is an "Open-source library and tools for audio and music analysis, description and synthesis" (https://essentia.upf.edu)

If you use Jupyter Lab / notebooks and therefore manage your Python environments using Anaconda, AND your machine is macOS, you will not be able to install Essentia out of the box. This is because:

pip install essentia is currently Linux only

Enable TCP port 2375 for external connection to Docker

See this issue.
Docker best practise to Control and configure Docker with systemd.

Create daemon.json file in /etc/docker:

 {"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}
