You can ignore the warning, the problem is you can't use Python 3.8 on macOS with the version of Ansible that Algo depends on. Fall back to the latest version of Python 3.7.

A change to the documentation that warns against Python 3.8 on macOS has been submitted, but the PR #1607 has been held up for some reason.

Thank you.

Can you point me in the right direction as to how I can use 3.7 instead of 3.8?

Unfortunately the Python packages from python.org don't come with an uninstaller, so removing the package takes several steps:

1. In Finder, delete the package found in /Applications.
2. In Finder, delete the rest of the package found in /Library/Frameworks/Python.framework.
3. In Terminal, undo the changes to your PATH by running: mv ~/.bash_profile.pysave ~/.bash_profile
4. In Terminal, remove the dozen or so symbolic links the package created in /usr/local/bin. Or just leave them because installing another version of the package will overwrite most of them.

Then download and install the latest version of Python 3.7 you can find on this page (currently 3.7.5).

Once you've done all that, open a new Terminal window or tab, download a new copy of Algo, and run the set of python3 commands to set it up again.
