Invert scroll direction for physical scroll wheels while maintaining "Natural" scrolling for trackpads on MacOS.
For some reason in macOS, toggling the "Scroll direction: Natural" option in Mouse settings also changes it in Trackpad settings despite being in separate places.
This application makes it so that scroll direction for physical scroll wheels is the opposite of what is shown in settings without messing with the scroll direction of the trackpad.
The issue is described here:

Unfortunately most/all solutions no longer work reliably if at all in Catalina.
brew install --cask unnaturalscrollwheels

Download the latest
.dmg
from the releases page, mount it, and copy the.app
to your applications folder like any other application. -
The application is not notarized since I haven't paid the yearly $100 fee to join the Apple Developer Program, you will need to right click on the
.app
and choose Open.
- The app requires accessibility permissions to "Control your computer". This is required to intercept scroll events, invert them and modify their deltas to disable acceleration and apply your settings.
That's it!
For the most part, things are self explanatory. One possible point of confusion may be how to modify your preferences once you've hidden the app from menu bar. To show preferences and to temporarily show the menu bar icon again, with the application running the background, simply open the application again which will display the preferences window.
