About Scroll Reverser
Scroll Reverser is a Mac app that sets scroll direction separately for trackpads and mice, including Magic Mouse. A common setup is natural scrolling for the trackpad with classic scrolling for the mouse. For wheel mice it adds a step size slider that sets how many lines scroll per wheel click.
Version 1.9 requires macOS 13.5 or later on Intel or Apple silicon, with older downloads available for earlier systems. It cannot reverse swipe gestures and does not work in iPhone Mirroring or the Calendar app, which use gesture-based scrolling.
