It’s not immediately clear on Mac OS how to start a Jupyter Notebook if you’re using Anaconda.
The actual executable is located at /Users/*YOURUSER*/opt/anaconda3/bin/jupyter-notebook but it can be a pain to either type the full link or even worse start the Anaconda application first just to open a notebook.
The easiest way I found is to make a symlink in your /usr/local/bin directory (make one if it doesn’t already exist) using the following command.
$ cd /usr/local/bin
$ ln -s /Users/*YOURUSER*/opt/anaconda3/bin/jupyter-notebook
Then you can start jupyter-notebook from anywhere in the terminal by just typing jupyter-notebook.
Alternative Method
I had to use the above solution since conda was not in my path but it seems there’s another solution that’s even simpler. Just open a terminal, navigate to your anaconda installation and run the conda with the following arguements.
$ cd opt/anaconda3/bin $ ./conda init zsh
