Installing Python on macOS

This guide will walk you through installing Python on your Mac.

1. Check if Python is Already Installed

Most Macs already have Python pre-installed, but it may be an older version.

Open Terminal (Applications → Utilities → Terminal) and type:

python3 --version
  • If you see Python 3.x.x, Python is already installed.
  • If it’s very old (below 3.10) or missing, follow the steps below.

2. Download Python

  • Visit python.org/downloads.
  • The website will suggest the best version for macOS.
  • Click Download Python 3.x.x (latest stable release).

3. Install Python

  • Open the downloaded .pkg file.
  • Follow the installer steps (click Continue until done).
  • This will install both Python 3 and IDLE (a simple code editor).

4. Verify Installation

After installation, open Terminal again and type:

python3 --version

You should see the version number of the newly installed Python ✅

5. Install pip (Package Manager)

pip is used to install extra Python packages.

In Terminal, type:

python3 -m ensurepip --upgrade

Check pip version:

pip3 --version

6. (Optional) Install Homebrew for Easy Updates

Homebrew is a macOS package manager. It makes updating Python easier.

Install Homebrew:

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

Then install Python via Homebrew:

brew install python
