AirScroll is a macOS utility that replaces the default scroll behavior with fluid, momentum-driven motion — making every wheel, touchpad, or peripheral feel like it was designed for your Mac.
What is AirScroll?
AirScroll is a system-level scroll enhancer for macOS that intercepts raw scroll input and reprocesses it with configurable easing curves, giving any mouse or trackball the same buttery feel Apple delivers on the built-in trackpad. If you have ever plugged a third-party Logitech or Microsoft mouse into a Mac and immediately noticed that the scrolling feels mechanical and abrupt compared to trackpad inertia, AirScroll is the fix.
It runs quietly in the menu bar, consuming almost no CPU or memory, and applies its magic globally — every app, every window, every scroll event. The difference is immediately apparent the moment you open a long document, a tall Figma canvas, or a deeply threaded Slack channel.
What does AirScroll do best?
AirScroll's strongest suit is its per-device sensitivity and easing customization — you can tune scroll speed, acceleration curve, and inertia duration independently for every connected input device. That means your ergonomic desk mouse can feel completely different from your travel scroll-wheel without toggling any system preferences.
- Momentum scrolling — kinetic coast after a fast flick, just like Apple's trackpad
- Per-device profiles — separate curves for each USB or Bluetooth mouse
- Direction reversal — natural or traditional scroll direction, independently of the trackpad setting
- Per-app overrides — disable inertia in precision tools like Logic Pro or Final Cut where exact scroll position matters
- Smooth line scrolling — eliminates the jarring line-by-line jumps common with mechanical scroll wheels
I have been running AirScroll daily with a Logitech MX Master 3 and the improvement over macOS's raw scroll handling is not subtle — it is night and day. Long-form reading in Safari and code navigation in VS Code both feel considerably less fatiguing.
How much does AirScroll cost?
AirScroll is free to download, with a trial period that lets you evaluate the full feature set before committing. A one-time purchase unlocks the app permanently — no subscription, no annual renewal. For a utility that touches every scroll event on your Mac indefinitely, the single-price model feels entirely fair.
Who should use AirScroll?
AirScroll is essential for anyone who uses a non-Apple mouse with a Mac — which covers a surprisingly large slice of power users who prefer a physical scroll wheel over the trackpad for extended desk sessions. Developers scrolling through long diffs, designers panning infinite canvases, writers working in full-screen documents, and anyone who spends hours a day in a browser will feel the benefit immediately.
It is less compelling if you work exclusively on the built-in trackpad, since macOS already delivers fluid momentum scrolling there. But the moment a USB or Bluetooth mouse enters the picture, AirScroll earns its place in your launch agents.
How does AirScroll compare to alternatives?
The most established competitor in this space is Mos, a popular open-source scroll smoother. Mos is free and does a solid job for most users, but AirScroll edges it out on configurability — particularly the per-device profile system and the per-application overrides, which Mos lacks. SteerMouse is another capable option, though it bundles broader pointer customization (button remapping, cursor speed) at a higher price point, which is overkill if smooth scrolling is all you need. LinearMouse is free and open-source, covering scroll smoothing and pointer acceleration tweaks, making it the closest free alternative to AirScroll's feature set — though I find AirScroll's easing curves feel slightly more polished in practice. If you are already paying for Logi Options+ for a Logitech mouse, its built-in smooth scrolling is decent but not tunable beyond basic speed — AirScroll gives you far more control over the feel.
The key differentiator AirScroll has over the whole field is that it feels like a finished, maintained Mac app rather than a community tool with an occasionally stale GitHub repo. Updates arrive promptly after macOS releases, which matters for a utility that hooks deep into system input events.
What are the best AirScroll alternatives?
If AirScroll does not fit your needs, the strongest alternatives are: Mos (free, open-source, lighter feature set), LinearMouse (free, broader pointer controls), and SteerMouse (paid, full pointer remapping suite). For Logitech users already invested in the MX ecosystem, Logi Options+ is worth trying first at no extra cost — but return to AirScroll when you want more granular easing control.
