To setup Python 3 from scratch, run the below commands on a new host with major supported platforms. Later during the runtime, either use python 3 command or python in python 3 virtual env. Use either pip3 or pip3.x (pip3.6 for example) to install packages based on the installed Python 3 version.
- Use Python 3 as the macOS default. Python's website has a macOS Python 3 installer we can download and use. If we use the package installation, a python3 fill will be available in /usr/local/bin/. Aliasing is a must since the Python binary stored in /usr/bin/ can't be changed. What's nice about an alias is that it's specific to our command-line.
- Some time back, I wrote about upgrading Python on macOS from the pre-installed version of 2.7 to the latest 3.x. Now, in this article, I will provide you the steps for upgrading PIP to it’s latest version on macOS. PIP is the abbreviation of Package installer for Python.
- Open the Terminal on your Mac. Now, enter the command python -version and press the Enter key. You can see the result in the next line itself, displaying the version of python installed on your Mac pc. But, if that command doesn’t work for you then you may try python3 -version and then press the Enter key.
Python comes pre-installed on macOS. The Apple-provided Python Framework is installed in /System/Library/Frameworks/Python.framework.
You can find several symlinks in the usr/bin/python directory.
You shouldn’t attempt to remove the pre-installed version of Python provided by Apple, as this may cause your operating system to malfunction.
If you would like to remove any third party Python framework that you may have installed, such as the ones found in python.org, this tutorial will provide you with step by step instructions on how to fully uninstall Python from your Mac.
Before we start, it is important to know that there are several things happening during the Python installation process.
- A folder will be installed in the Applications directory. The folder contains IDLE, PythonLauncher, and the Build Applet tool.
- A framework will be installed in the /Library/Frameworks/Python.framework directory. This path includes the Python executable and a number of libraries.
- Several symlinks to the Python executable will be placed in the /usr/local/bin directory.
You are required to remove all these items to completely remove Python from your system.
Keep in mind that there are two versions of Python available as Python 2 and Python 3. If you have installed both the versions and would like to delete just one, specific instructions on how to do so are mentioned in each of the steps.
Step 1: Manually remove the Python folders from the Applications folder
In Finder, navigate to the Applications folder.
Move any Python folders that are installed into the Trash. If you would like to remove a single version, only remove the file relevant to that version.
If the following dialog box gets prompted, please enter the password.
Next, go to the Trash directory.
Right-click on the folder and select Delete Immediately.
Deleting the Python folders will not completely uninstall Python from your system. To completely uninstall Python, please go through the following steps.
Step 2: Remove the Python Framework from the /Library directory
We will use the command line starting from this step.
Press command + space to bring up the Spotlight Search.
Search for Terminal and open it.
In the terminal type the following command to remove all the Python Frameworks present in the /Library directory and hit enter.
sudo rm -rf /Library/Frameworks/Python.framework
If prompted to enter the password, please do so.
Download Python 2.7
If you would like to delete only a specific version of Python, please update your command as below.

Step 3: Remove Python symbolic links
Now that we deleted all python directories and files, there may be links in your system that may still be referencing the folders that we have already deleted. This step will ensure that all such links will be deleted.
There are two ways in which this step could be performed. Let’s look at both the ways in detail.
1st Method: Using Homebrew
It is highly recommended that you install Homebrew if you do not have it already. Please install it by typing the following command in the Terminal.
/bin/bash -c '$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)'
(Please refer to the Homebrew official site https://brew.sh for more information)
You can easily find broken symbolic links by running the command.
brew doctor
The result will look like this (Please note that your result may look different)
Run the command ‘brew cleanup’ as instructed to remove all broken symlinks.
2nd Method: Manual deletion
The symlinks referencing Python frameworks are in the /usr/local/bin directory. If you would like to see the broken symlinks, please use the following command.
ls -l /usr/local/bin | grep ‘./Library/Frameworks/Python.framework’
(The path ‘/Library/Frameworks/Python.framework’ should be replaced by what you chose in Step 2’)
The result will show you all the links that are referencing the Python frameworks.
To delete these broken symlinks, please use the following commands.
To enter into the directory
To delete the broken symlinks in the directory
ls -l /usr/local/bin | grep './Library/Frameworks/Python.framework' | awk '{print $9}' | tr -d @ | xargs rm*
(Please keep in mind that the path ‘/Library/Frameworks/Python.framework’ should be changed according to the path you chose in Step 2.)
There you have it. Now your system is completely free from Python. Now you can download and install a fresh copy of Python or leave it as it is.
How to Update Python on Mac: Python is a common programming language commonly used by both novices and long-time developers. Current models of Mac OS come with Python 2.7.x enabled (or Python 2.6.1 if an earlier version of Mac OS X is enabled), although other Python users will choose to upgrade Python to a later version such as Python 3.8.x or later.
This article would explore how to get an improved version of Python 3 on Mac by discussing two separate ways to install Python 3 quickly and easily on a Computer.
Notice why we said install Python 3, not upgrade to Python 3, as the way that operates is updating Python 3 when keeping Python 2 on the Mac concurrently.

This is important since certain Mac applications evidently depend on Python 2 support, and if you seek to update Python 2.x to Python 3.x in Mac OS, you will inevitably notice anything is wrong, even desperately and. Having this in mind you shouldn’t attempt to upgrade the latest pre-installed Python release on a Mac, then you’ll only get a complete support Python3 co-install.
How to Install the Updated Python 3 in Mac OS:
The best way to update Python 3 is maybe by utilizing the python.org module installer.
Go to the download page here for Python.org, and access the new Python installer kit.
Run the Python kit, then install Python 3 on the Mac.
Installing Python 3 on Mac OS:
Configuration of Python 3.8.x includes about 100 MB of disk space. Installation is quick, and on the Mac, you will have Python 3.x alongside Python 2.x.
Remote control mac air. If you have enabled Python 3 you can notice a Python3 folder inside your Mac’s /Applications directory. You can also notice the easy IDE called IDLE in the directory /Applications / MacPython3/, which essentially offers you the same Python IDE you’d experience if you run’ python3’ at the Terminal command prompt.
Remote desktop mac sierra. You can even run Python 3.x via Homebrew on a Laptop, which is my favorite form as a homebrew consumer.
How to Install Python 3.8 with Homebrew:
Download Python 2.7 For Windows
Installing a revised edition of Python 3.8 (as of writing time) with Homebrew is super fast. Of course, until you can use the Homebrew system you would need Homebrew enabled on the Desktop, however, if you’re involved in playing about with Python than Homebrew would definitely cater to you anyway.
If you don’t know how to run Homebrew on Mac OS, we’ll assume you already have Homebrew.
If you’re downloading the modified Python 3 with the software installer or Homebrew, the original build of Python 2.7 that comes preinstalled for Mac OS and Mac OS X should always be loaded, totally unchanged, and will operate as normal with the easy “python” command.
How to Check What Version of Python is Currently Installed in Mac OS:
Simply typing in the following command from the Terminal program should show what edition of Python is currently enabled:
python –version
In macOS, you can consider that in any variety usually Python 2.7.x, like 2.7.4 or 2.7.10 or the same.
After downloading Python with Homebrew or with the Software Installer, you can test Python’s latest new version with:
python3 –version
