Jupyter Notebook is an open-source web application that allows you to create and share documents containing live code, equations, visualizations, and narrative text. It's widely used for data cleaning and transformation, numerical simulation, statistical modeling, data visualization, and machine learning. While Jupyter Notebook is not exclusive to any operating system, it can be seamlessly integrated into the macOS environment.

In this article, we will guide you through the process of installing and running Jupyter Notebook on a Mac. This includes setting up the necessary dependencies, installing Jupyter via pip, and running your first notebook.

Examples:

1. Install Homebrew (if not already installed): Homebrew is a package manager for macOS that simplifies the installation of software. Open Terminal and run the following command:

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install Python: Jupyter Notebook requires Python. You can install Python using Homebrew:

   brew install python

3. Install Jupyter Notebook: Once Python is installed, you can use pip (Python's package installer) to install Jupyter Notebook:

   pip3 install jupyter

4. Run Jupyter Notebook: After the installation is complete, you can start Jupyter Notebook by running the following command in Terminal:

   jupyter notebook

   This will open a new tab in your default web browser with the Jupyter Notebook interface.

5. Create a New Notebook: In the Jupyter Notebook interface, click on the "New" button and select "Python 3" to create a new notebook.

6. Write and Execute Code: You can now write and execute Python code in the notebook cells. For example:

   print("Hello, Jupyter!")

   To run the code, press Shift + Enter.

7. Save and Share Notebooks: You can save your notebooks by clicking on "File" > "Save and Checkpoint". Notebooks are saved with a .ipynb extension and can be shared with others.
