Mos makes a regular mouse wheel scroll smoothly on macOS, closer to how a trackpad feels. It also lets you put extra mouse buttons to work.

**Key features:**

- Smooth out stepped wheel scrolling with an inertia-based algorithm.
- Tune the step, speed and duration of the scroll curve.
- Give each app its own scroll profile.
- Bind mouse buttons to actions like Mission Control, switching Spaces or the App Switcher.
- Map keys on Logitech mice.

Mos supports macOS 10.13 or later and can be downloaded directly, installed via Homebrew or built from GitHub.
