Coming from https://mail.python.org/archives/list/[email protected]/thread/XEMCNFIXKCFZKIWV5GRLFFJZCWWK3FYQ/

The "Using Python on Mac" documentation page (Doc/using/mac.rst) is significantly out of date and has various issues arising out of this:

• It mentions that macOS comes with Python 2.7 by default, but that it was removed in 12.3
• It discusses universal binaries (used during the PowerPC -> Intel transition) but not the universal2 binaries (the ongoing Intel -> ARM transition).
• It consistently refers to "MacPython", which seems to be the historical name used? It's likely clearer to say Python on macOS today, so that's likely a worthwhile update.
• It refers to IDLE as "IDE". :)
• It suggests doing python setup.py install, something that the setuptools developers actively discourage and want users to move away from.
