Magic Mouse UX fixes for macOS.
The main one: your mouse stops scrolling the page every time you click.
Free. MIT-licensed. Requires macOS 13 or later.
The Magic Mouse's entire top shell is a touch surface — and it stays live while you click. You press down, your finger rolls half a millimetre, and the page jumps. Drag a window and the document scrolls out from under it. Click a link and the link moves first.
macOS has no setting for this. CalmMouse is that setting — a small menu-bar app that swallows Magic Mouse scrolling while any of its buttons is held, and keeps swallowing for a moment after, to catch the trailing swipe your finger makes as it lifts.
Everything applies only to the Magic Mouse. CalmMouse identifies the physical device behind every event, so your trackpad and any other mouse pass through untouched.
A light single-finger tap left-clicks — no need to press the mouse down. Adjustable Firm↔Light sensitivity, and taps are auto-rejected while you're scrolling, clicking, resting a finger, or just grazing the shell. Double- and triple-taps become real double- and triple-clicks.
Tap, touch again, and go: the button presses down when you actually start moving and releases when your finger lifts. A finger that just comes back to rest never presses anything — and a quick second tap is still a double-click, so selecting a word and extending it works.
Rest two fingers on the surface together and hold — after a moment the button presses down. Move to drag, lift either finger to drop. Fingers that land one after the other are grip, not gesture, and never trigger it.
Any setting, overridden per application. Disable Magic Mouse scrolling entirely in Figma, block horizontal scroll in Excel, drop momentum in your code editor. Rules follow whichever app is in front.
Once a scroll commits to vertical or horizontal, the other axis is zeroed for the rest of the gesture. No more diagonal drift.
A gesture has to travel a minimum distance before it counts — so a finger merely resting on the shell can't jitter the page.
Turn off the coasting tail after a flick, for the Magic Mouse alone. macOS's own momentum setting is all-or-nothing, system-wide.
Map ⌘, ⌥, ⌃, or ⇧ + scroll to horizontal scrolling, inverted scrolling, zoom — or nothing at all.
A notification when the mouse drops below a threshold you choose, so it doesn't die mid-afternoon.
Restrict taps to the front of the surface, away from the side edges — so the fingers gripping the mouse can't click. Adjustable depth.
No jargon, no manual. Every switch says what it does — and hovering any setting plays a little animated preview of the behavior it changes. The switches you flip often live right in the menu bar.
Permission
Troubleshooting
CalmMouse reads mouse events through a system event tap, which macOS gates behind an Accessibility permission — you stay in control.
No trial, no license key, no email. Download it, drag it in, done.
Requires macOS 13 or later and a Magic Mouse.
You get CalmMouse.app — drop it in /Applications.
Releases aren't notarized yet, so macOS asks once. Right-click the app, choose Open, then Open again.
System Settings → Privacy & Security → Accessibility → enable CalmMouse. It starts working within two seconds — no relaunch needed.
