Mos

brew install --cask mos v4.2.1,20260531.1

Smooth mouse scrolling with per-app settings and independent scroll direction control.

Why you might care

Mos is free and lets you fine-tune scrolling behavior per application, which is especially useful if you regularly switch between external mice and trackpads or need different scroll directions for different apps. It's lightweight and stays in the menu bar.
