MOPUp is the macOS Python.org Updater.
If you prefer to use the binary installers from python.org, it's easy to forget to update them. This is a program that does that; it updates them. Just pip install mopup
into a virtualenv using the Python you are using, run mopup
and provide your password when required.
Normally, it does this using a CLI in the background, but if you'd prefer, you can run it with --interactive
for it to launch the usual macOS GUI Installer app.
