You'll need to install Python 3 before you can run Algo. Python 3 is available from several different packagers, three of which are listed below.
**IMPORTANT:** At this time you **cannot** use Python 3.8 or later with Ansible on macOS. Choose a recent version of Python 3.7 instead.
## macOS 10.15 Catalina
Catalina comes with `/usr/bin/python3` installed. This file, and certain others like `/usr/bin/git`, start out as stub files that prompt you to install the Developer Command Line Tools the first time you run them.

Download the most recent version of Python and install it like any other macOS package. Then initialize the CA certificate store from Finder by double-clicking on the file `Install Certificates.command` found in the `/Applications/Python 3.8` folder.
When you double-click on `Install Certificates.command` a new Terminal window will open. If the window remains blank then the command has not run correctly. This can happen if you've changed the default shell in Terminal Preferences. Try changing it back to the default and run `Install Certificates.command` again.
After installation open a new tab or window in Terminal and verify that the command `which python3` returns either `/usr/local/bin/python3` or `/Library/Frameworks/Python.framework/Versions/3.7/bin/python3`.
