Python is a popular programming language that is widely used by both beginners and professional developers. Modern versions of Mac OS support Python 2.7.x (or Python 2.6.1 in older versions), but many users need to upgrade to Python 3.6 or 3.7.

MacOS comes with Python pre-installed. But it's Python Version 2.7, which is now deprecated (abandoned by the Python developer community). The entire Python community has now moved on to using Python 3.x (the current version as of writing this is 3.9).

Today I will explain how to install the Python 3 update on a Mac in two different ways.

Note that I mean “install update” rather than “upgrade”, since Python 2 will remain on the Mac with this method. Some Mac programs require Python 2, and when upgrading they may start to malfunction or stop working altogether. Therefore, we will not update the installed version, but install Python 3 in parallel. Python 3 and Python 2 can coexist on the same Mac without conflicts, just the commands will differ slightly.

How to install Python 3 in macOS with Installer

The easiest way is to download the Python installer from the python.org website.

Mac install python 3.7.3
  • Visit Python.org and download the latest available Python installer file;
  • Run the downloaded file and install Python 3.x on Mac.
  • Python 3.6.x requires about 100MB of available disk space. The installation process is very fast;
  • When Python 3 is installed, you will see the Python3 folder in /Applications on your Mac. You will also see IDLE in the /Applications.

Next method will show you how to install Python 3.x on a Mac through Homebrew.

If you haven’t Homebrew in your system, you can take script for Homebrew installing here. This script installs Homebrew to /usr/local so that you don’t need “sudo” when you brew install. It is a careful script; it can be run even if you have stuff installed to /usr/local already. It tells you exactly what it will do before it does it too. You have to confirm everything it will do before it starts.

Now to install Python 3 via Homebrew, run the following command in Terminal:

When Python 3 is installed on a Mac, you can start the program with:

In any case, after installing Python 3 on a computer, the version of Python 2.7 will still remain on it, and you will be able to use it.

Once again, both versions of Python can coexist without conflicts.

Note: Once again, I want to remind you that you do not need to upgrade Python 2.x to Python 3.x, because this can lead to program malfunctions. Just install the updated version in parallel.
