How to Install and Properly Set Up Python 3 - macOS Catalina or Big Sur

In this video, I walk you through the process of installing Python 3 and properly setting it up so that it becomes the default instead of the System Python 2.

This video is for users with macOS Catalina or Big Sur.

I spent 5 HOURS scouring the internet trying to figure out how to make Python 3 the default in the terminal on my Mac and eventually just gave up. However, after following along with your video, I was finally able to get Python 3.9 as the default!! I look forward to watching the rest of the vids on your channel :)

I was lost and confused when I started searching for the solution on git and StackOverflow. Then I found your video. Thanks, man.

Thank you so so so much, every single time im coding in python I would get extremely discouraged because packages would not download correctly but with your help it finally works!!! I have Python downloaded correctly for the first time. Thank you so much!!!

Excellent video, thank you. Best of the many I searched through trying to accomplish this. I really appreciate you mentioning that the "rc" at the end of .zshrc means run config and showing the cat command to verify the file contents. As a second-year student who knows a ton of Linux commands and filesystem types but very little experience actually working within these files, examples and connections like those really help.

Thank you so much for this video. So much easier to follow than any article or tutorial I've tried

Thank you for this tutorial. I'm new with Mac and I didn't know how to do this. Really straightforward video and easy to understand

[shibhuk]

Thank you so much. I am just stating to learn programming don’t know anything. I was trying to find a solution to run Python through Atom but it kept showing Path error. Searched everywhere nothing worked. Followed all your steps along with the new path in the comments finally it worked.

THANK YOU

[mariamavagyan]

This worked for me! I'm on OS X Catalina. Perhaps the most challenging part was switching the default shell from Bash to Zsh. It finally worked after checking these three (3) things:

1. run cmd in Terminal (chsh -s /bin/zsh)
2. System Preferences (users, right-click Adv settings, shell dropdown)
3. Terminal Preferences (general, default shell)
 see this forum for more help:

For the M1 Macs there are few more steps to be done in terminal:
Run the commands in that order in terminal, you'll be editing the path and creating the missing .zshrc file, exporting the path to this new file.

cd /opt/homebrew/bin/

PATH=$PATH:/opt/homebrew/bin

cd

touch .zshrc

echo export PATH=$PATH:/opt/homebrew/bin >> .zshrc
