Installing Homebrew on Mac OS X prior to El Capitan (that is Yosemite, Mavericks and others) used to be a breeze. But with a new change in OS X El Capitan called SIP - installing Homebrew has become a bit complicated. You need not worry, I have got you covered. Homebrew Logo - Mac. Aug 12, 2017 Step 1: In order to install Homebrew on your Mac you need to have Xcode installed. If you have full Xcode already, then proceed to the next step. If you don’t and you also don’t want to install full Xcode on your Mac, then you can also download command-line tools for Xcode instead by running the following command in Terminal.

Being a software engineer, you often come across many instances where you would require to have Python installed on your Mac.

However, the issue is most modern macOS versions come with rather with Python 2.7.x installed and not the newer, modern version like Python 3.6.5 or Python 3.7.2 (which is the most up-to-date version right now).

This short guide is written to show you how to properly install Python 3 on a Mac OS Xcomputer.

Before you jump into the guide, do take note that there are multiple ways to install Python 3 on a Mac but with this guide, I’ll show you the two easiest ways to do this, step-by-step.

Personally, the way I did it was using a package manager like HomeBrew (it’s okay if you don’t understand what it is). Again, I’ll show you how to do this method down below.

Wait, how do I check if Python 3 is already installed on my Mac?

Simple. Open up your Terminal and type the following line python --version and then hit your Enter key:

You should see the python version that is currently installed on your Mac.

How to Install Python 3 on macOS: 2 Ways

1. The Simplest Way.

Perhaps the simplest way to install Python 3 on macOS.

This is for you especially if you’re a newbie (though I still strongly recommend you try the HomeBrew method below) or if you don’t want to deal with copy-pasting code into your Terminal and downloading other software.

Type the title of your favorite TV show or movie and click the Enter button.

Sign in using your Netflix login details, email address, and password.Step 2: Browse genre columns: Tap or click on the genre title to browse the movie or TV shows.Step 3: Search for Movies and TV shows: Click on the magnifying glass icon located on the upper right corner to access search.

Here’s how to install Python 3 on your macOS:

Jump into Python.org downloads page and simply just download the latest Python version.

Next, run the Python Installer to install Python 3 onto your Mac.

Note

The Python installation may require about 100MB of disk space to install. Once you’ve installed Python 3 you can have it alongside Python 2 without having to delete the latter from your Mac.

Great! Now once Python 3 is installed, you’ll be able to find it within the Applications directory of your Mac. You’ll also find here a simple IDE called “IDLE.app” which gives you a basic Python IDE.

Help! Where do I find the Applications directory?

If you can’t find the Applications directory, simply go to Finder by clicking the Finder icon in the Dock (it’s usually the first icon from the left side of the Dock). From there simply, go to the Go menu and select Applications.

Done. If you got yourself lost through the process, you can comment down below.

Next up, I’ll show you how you can install Python 3 using HomeBrew onto your macOS. This is my preferred way and it is just as simple as the method before but it will make your life a whole lot simpler, in the long run, using Python.

2. Install Python 3 on Mac using HomeBrew.

This method is dead-ass simple and a little fun. 🙂

First of all, you’ll need to have this thing called HomeBrew installed on your Mac. Homebrew is basically a “package manager”. A package manager is an application that helps you install the stuff you need that Apple (or even your Linux System) hadn’t installed in the first place for you.

It’s simple, fast and safe.

Second, you will need to have installed XCode onto your Mac. If you’re thinking of learning how to program or creating iOS apps on your Mac, then it’s good to have XCode installed. We will be using XCode to install HomeBrew application.

Note

If you have already installed XCode onto your Mac you can skip step 1 and jump straight to step 3.

Here are the steps to install XCode, HomeBrew as well as install Python 3 using HomeBrew onto your Mac:

Jump into your Terminal app on your Mac and run the copy/paste the following command into the Terminal to install XCode onto your Mac:
Simply click through all the confirmation crap that XCode shows. It may take a little while to install XCode since it is a large program.
Great! Now that you have XCode installed, you can install HomeBrew! To install HomeBrew, simply copy/paste the following command into your Terminal:

Note

You can confirm the HomeBrew installed correctly by running the command: below:

You’ve installed HomeBrew! Now let’s install the Python 3, the reason why you’re here. To install the latest version of Python, just copy/paste the following command into your Terminal:

Note

You can confirm which version of Python was installed all by running the command below (the exact same command you tried earlier in this guide). It should show up as follows:

Finally, let’s run our new Python 3. Simply enter python3.

Voila! You have now installed Python 3 successfully if you see something similar in your Terminal:

Bonus

•If you want to exit, type exit() and then hit your Return button on your keyboard. You can also hit both Control and D keys at the same time instead of the Return key.

•Remember I mentioned you can run both your new Python 3 alongside your old Python 2? Yup. Simply type python into the Terminal to run with Python 2.

The easiest way to install a number of Unix style applications and open source software onto macOS Catalina, Mojave and earlier Sierra OS versions is via a package manager, unfortunately, macOS Catalina doesn’t come with one, but fortunately, some good folks care, they come in the form of Homebrew.

The install of Homebrew also works on macOS Catalina, macOS Mojave, (High)Sierra, El Capitan, and Yosemite, so macOS 10.10 – 10.14

Homebrew isn’t the only option, also available is MacPorts and Fink but Homebrew is the newest and most popular of the trio.

Install Homebrew

To download install Homebrew run the install script on the command line as below and let the script do its thing:

If you don’t have Apples Xcode Command Line Tools installed it will prompt you to install to carry on with the Homebrew installation and download the Command Line Tools.

Then Homebrew is installed.

After this Homebrew is installed and ready to install other apps.

To get started run brew help can give some command example usage.

To check for any issues with the Homebrew install run:

One issue that typically comes up is an outdated or missing version of Xcode.

For the latest Catalina, brew doctor will warn that the Homebrew install won’t be 100% if Xcode is not up to date, so update Xcode from the App Store.
