Mos

Mos is a lightweight utility that improves scrolling with external mice on macOS, making movement feel smoother and more consistent across apps. Customize scroll direction and speed, fine-tune behavior to match your preferences, and fix the common mismatch between trackpad and mouse scrolling. It’s especially useful if you switch between input devices or use a mouse that feels too fast, too slow, or jittery by default. With simple settings and a set-it-and-forget-it approach, Mos makes everyday navigation more comfortable and precise.
