How to Completely uninstall Python 3 on Mac

Uninstalling Python 3 Completely on macOS

While it’s generally not recommended to uninstall Python entirely, there might be situations where you need to. Here’s a guide on how to completely remove Python 3 from your Mac:

Understanding the Removal Process:

Uninstalling Python 3 on macOS involves two main steps:

1. Removing Application Files: This includes deleting the Python application directory and any associated launcher scripts.
2. Removing Framework Files: These are system-level files that store Python libraries and binaries. Caution is advised in this step, as deleting essential system files can cause problems.

Steps for Uninstallation:

1. Remove Application Files:

   • Open Finder.
   • Navigate to the Applications folder (usually accessible on the sidebar).
   • Locate the folder named “Python 3.x” (replace “x” with your specific version number, e.g., “Python 3.8”).
   • Right-click on the folder and select “Move to Trash.”
   • Empty the Trash to permanently delete the application files.

2. Remove Framework Files (Caution):

   Important: This step requires using Terminal commands and carries a risk of deleting essential system files. Proceed with caution and only if you’re comfortable with the command line. It’s recommended to back up your Mac before proceeding.

   • Open Terminal (located in Applications > Utilities).

   • Identify Python 3 Installation Path:

     • Type the following command and press Enter:

       Bash

       which python3
       

     • This will display the path to the Python 3 binary. Note down the entire path, including the version number (e.g., /Library/Frameworks/Python.framework/Versions/3.8).

   • Remove Framework Directory:

     Warning: Double-check the path before proceeding.

     • Type the following command, replacing [path_to_python_framework] with the actual path you obtained in the previous step:

       Bash

       sudo rm -rf [path_to_python_framework]
       

     • Press Enter and type your administrator password when prompted.

     • This command will permanently delete the Python framework directory and its contents.

   • Optional: Remove Symbolic Link (if present):

     • In some cases, a symbolic link might point to the deleted Python binary. To remove it, use the following command, replacing [path_to_python3_binary] with the actual path:

       Bash

       sudo rm -rf [path_to_python3_binary]
       

• Verification:

  • Open a new Terminal window.

  • Type python3 and press Enter.

  • If Python 3 is uninstalled correctly, you should see an error message indicating “python3: command not found.”

Additional Considerations:

• If you have multiple versions of Python installed, repeat these steps for each version you want to remove.
• Be aware that some applications might rely on Python. Uninstalling Python could break their functionality.
• Consider using a virtual environment manager like venv or conda to manage different Python versions and their packages without affecting your system-wide Python installation.

By following these steps carefully, you can completely uninstall Python 3 from your Mac. Remember, proceed with caution, especially when dealing with Terminal commands. If you’re unsure about any step, it’s always best to consult documentation or seek help from someone familiar with macOS and Python.
