It is told that you can reset Audacity 3.1.3 Preferences and Settings during an install (a “clean” install) by selecting an option during install. The Mac install consists of moving an icon between two locations. There are no options or selection opportunities. How do you do a Mac clean install?
“Reset Configuration” resets “most” of Audacity’s preferences (the audacity.cfg file).
I don’t recall which prefs are not reset, but it resets all of the important ones.
It does not touch plug-ins.
