## What it is
Mos is a free, open-source macOS menu bar utility that smooths mouse wheel scrolling to feel like a trackpad and allows independent scroll direction settings. It also supports per-app scroll profiles and mouse button remapping, including Logitech HID++ devices.

## Use cases
- make mouse wheel scrolling smooth on mac like a trackpad
- reverse mouse scroll direction independently on macos
- remap mouse side buttons to actions on mac
- configure per-app scrolling behavior
- smooth horizontal scrolling for a mouse
- bind logitech mouse buttons on macos

## When to choose
- you use a regular mouse on macOS and find wheel scrolling jerky
- you want scroll direction reversed for the mouse only, not the trackpad
- you want mouse buttons bound to Mission Control, spaces, or scripts
- you use a Logitech mouse and want button events without Logi Options+

## When to avoid
- you are on Windows or Linux - Mos is macOS only
- you need a cross-platform or CLI-only solution
- you cannot grant accessibility permissions in a managed environment
- you need a fully permissive open-source license - it is CC BY-NC 4.0
