How to Open Jupyter Lab in your favourite browser other than system default browser in Mac OS: A Step-by-Step Guide

Are you tired of Jupyter Lab opening in your default browser? Would you prefer to use Google Chrome or another browser of your choice? This guide will walk you through the process of configuring Jupyter Lab to open in your preferred browser, with a focus on using Google Chrome.

The Challenge

 

Many tutorials suggest using the command prompt to modify Jupyter's configuration. However, this method often results in zsh errors and permission issues, even when the necessary permissions seem to be in place. This guide offers a more reliable solution that has proven successful for many users.

 

Step-by-Step Solution

 

1. Locate the Configuration File

- Open Finder and navigate to your user folder (typically named after your username).

- Use the keyboard shortcut Command + Shift + . (full stop) to reveal hidden folders.

- Look for a hidden folder named .jupyter.

- Within this folder, you'll find the jupyter_notebook_config.py file.

 

2. Edit the Configuration File

- Open jupyter_notebook_config.py in your preferred text editor.

- Add or modify the following lines:

 

#import webbrowser

c.NotebookApp.browser = u'open -a /Applications/Google\ Chrome.app %s'

 

Note: If you prefer a different browser, simply replace Google\ Chrome.app with Firefox.app or Brave.app as appropriate.

 

3. Save and Close

- Save your changes and close the text editor.

 

The Result

 

After implementing these changes, Jupyter Lab will open in Google Chrome (or your chosen browser) when launched from the terminal, regardless of your system's default browser settings.

 

Why Choose a Chromium-Based Browser?

 

Many users opt for Chromium-based browsers like Google Chrome or Brave for Jupyter Lab due to the wider availability of extensions designed for these browsers. This compatibility can enhance your Jupyter Lab experience with additional features and functionalities.

 

Troubleshooting

 

If you encounter any issues:

- Double-check that you've correctly located the jupyter_notebook_config.py file.

- Ensure there are no typos in the added configuration lines.

- Verify that the path to your chosen browser application is correct.

 

By following these steps, you should be able to customise your Jupyter Lab experience to open in your preferred browser, optimising your workflow and productivity.

 

Remember, the beauty of Jupyter Lab lies in its flexibility and customisation options. Don't hesitate to experiment with different settings to find what works best for you!


Happy coding!!!
