A better approach, in my opinion, is to instead use the popular package manager Homebrew which automates updates and juggling multiple versions of Python on a computer. The official Python website even recommends downloading it directly, however this approach can cause confusion around PATH variables, updates, and uninstalls. There are multiple ways to install Python 3 on a MacOS computer. And since Python 2 will no longer be officially supported as of January 1, 2020, you should really use Python 3 instead. Historically MacOS came preinstalled with Python 2, however starting with macOS Catalina 10.15 (released in October 2019) this is no longer the case. Time to take a deeper look at this upgrade of Pyton to Python 3 and how to solve the problems that come with it. More details about Python 2 support in pip, can be found at A future version of pip will drop supportįor Python 2.7. Python as Python 2.7 won't be maintained after that date. the message I saw in my terminal was: DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. The first time I read it I thought I will fix it when I need to. When I reinstalled my iMac with macOS Catalina in January 2020 I stubbled upon a error that I had seen before but I convenience ignored every time it popped-up.
