Python 3 on older macOS

Python 3 is required to run wikiproxy, TrollRestore, and SundanceInH2A.

• If you are on macOS 11 Big Sur or older, Python 3 is likely not installed on your system.
• If you are on macOS 12 Monterey or newer, installing Xcode Command Line Tools includes Python 3, so the installation steps below are usually unnecessary.

1. Open Terminal and run:

   python3 --version

   • If it prints a version such as Python 3.11.9, Python 3 is already installed. You should still complete the certificate installation step below if you installed Python from the official website.

2. If you instead see:

   python3: command not found
   

   Download and install Python 3:

   https://www.python.org/ftp/python/3.12.5/python-3.12.5-macos11.pkg

• Note: Python 3.12.5 is the newest official Python release that supports macOS 10.11 El Capitan.

3. After installing Python, open Applications, open the Python 3.12 folder, then double-click Install Certificates.command.
   • This step is mandatory, do not skip it!
