Mos vs LinearMouse vs Mac Mouse Fix vs LinguaX
There are several good macOS mouse utilities, and they overlap in confusing ways. Mos is the classic free smooth-scroller. LinearMouse focuses on pointer acceleration and per-device settings. Mac Mouse Fix adds gestures and remapping. The catch is that many people end up running two or three of these at once — one for scrolling, one for acceleration, one for gestures — which is exactly the kind of stack that causes conflicts. This page compares all four honestly and shows where LinguaX fits as a single app.
The Tools at a Glance
- Mos — free, open source, focused on smooth scrolling and reverse scroll. Excellent at its one job; does not do button mapping or gestures.
- LinearMouse — free, open source, focused on pointer speed/acceleration and per-device tuning, with some button remapping. Less about scroll smoothing and gestures.
- Mac Mouse Fix — affordable, strong on gestures and button remapping with good smooth scrolling. A capable all-rounder.
- LinguaX — native, under 5MB, mouse-first: smooth scrolling, button/gesture mapping, pointer speed, per-app overrides — plus input-source automation as a bonus.

The Real Decision: One Tool or Three
If you only need smooth scrolling, Mos is a fine free choice. If you only need acceleration tuning, LinearMouse is excellent and free. The trouble starts when you need all of it — smoothing and acceleration and gestures and per-app behavior — because stacking Mos + LinearMouse + a remapper means three event taps fighting over the same input, which is a common source of jitter and dropped clicks.
LinguaX is built to be the single app in that slot:
- One event pipeline for scrolling, speed, buttons, and gestures — no inter-tool conflicts.
- Broad model recognition for accurate per-device setup.
- Per-app and per-axis control where the free tools are global-only.
- And the bonus layer the others do not have: automatic input-source switching by app and by website.
Honest summary: keep Mos or LinearMouse if a single free feature is all you need. Choose LinguaX when you want one native app to replace the whole stack — and you get input automation thrown in.
