Jupyter not Launching after Updating to MacOS 10.12.5

If you have been itching to update the operating system on your shiny Mac, beware that there is a broken link when launching Jupyter.

Do not panic, simply follow these simple steps:

  • Open a terminal and type the following command:
jupyter notebook --generate-config
  • In the terminal navigate to the place where the configuration file is. In other words, type the following:
cd ~/.jupyter/jupyter_notebook_config.py
  • Open the jupyter_noteebook_config.py file and look for a line that says:
# c.NotebookApp.browser = ''

Change the line as follows: Delete the hash and write the name of your browser in between the quotes.

For SAFARI it would look as follows

c.NotebookApp.browser = 'safari'

If you are a CHROME supporter, the command looks a tad bit more complicated:

c.NotebookApp.browser = 'open -a /Applications/Google\ Chrome.app %s'
  • Save the script and close it.
  • Restart your terminal and launch Jupyter…

Et voilĂ !
