Scroll Reverser

Scroll Reverser is a utility created by Nick Moore of Pilotmoon Software to reverse the direction of two-finger scrolling on trackpads of Apple notebooks running versions of Mac OS X prior to 10.7 (Lion). It also supports all current versions of macOS, including Apple Silicon.

Description
This reversal mimics the natural scrolling feature that had been introduced in the Trackpad preference pane to make trackpad gestures more similar to that of iPad usage. It also has the ability to reverse scroll axes independently of one another and apply the reversal to mice as well.
