Choose which python to use from some popular options, in this order:

  1. python.org https://www.python.org/downloads/
  2. MacAdmins https://github.com/macadmins/python
  3. Munki https://github.com/munki/munki
 If none of these are on disk, then fall back to Apple's system python,
 which can be installed via the Command Line Tools.

 "What about python 2, which Apple still ships," you ask?
  Outset does not support python 2, which was sunsetted on Jan 1, 2020.
  See https://www.python.org/doc/sunset-python-2/.
  If you choose to continue to use python 2, you'll want to create the symlink via other means,
  with something like: /bin/ln -s /usr/bin/python /usr/local/outset/python3
