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).
Packages for macOS with Python 3.7¶. Platform: MacOS 64-bit. Python version: 3.7. Number of supported packages: 667. I was working on Tensorflow object detection project, for this I am using Anaconda 3 with python 3.7 but I am facing some issues while running object detection demo, I read couple of posts here on stackoverflow and found that it can be solved by using Anaconda with python 3.6 but this version is not available at Anaconda's download page, there are only two versions i.e for Python 3.7. If you had chosen a Python 3 version of Anaconda (like the one in the image above), you will get an output similar to above. If you had chosen a Python 2 version of Anaconda, you should get a similar output to the one below. Python -version 2 - Another good way to test your installation is to try and open a Jupyter Notebook.
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.
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.

Note
Do not install as Administrator unless admin privileges are required.
Choose whether to add Anaconda to your PATH environment variable.We recommend not adding Anaconda to the PATH environment variable, since thiscan interfere with other software. Instead, use Anaconda software by openingAnaconda Navigator or the Anaconda Prompt from the Start Menu.
Choose whether to register Anaconda as your default Python. Unless you planon installing and running multiple versions of Anaconda or multiple versions ofPython, accept the default and leave this box checked.
