Separate scroll direction for your mouse and trackpad on macOS — because they shouldn't be tied together.
macOS forces the same "Natural" scroll direction on both your trackpad and mouse. If you prefer natural scrolling on your trackpad but traditional scrolling on your mouse (or vice versa), you're out of luck. SaneScroll fixes this.
Forked from UnnaturalScrollWheels by ther0n. Full credit to the original developer for creating this essential utility.
The original UnnaturalScrollWheels has been largely unmaintained since August 2022. The original developer no longer has a paid Apple Developer account, so builds are unsigned and trigger macOS security warnings.
SaneScroll is a maintained, signed and notarized fork — it installs and runs without any security workarounds. No xattr commands, no "damaged app" warnings, no "unidentified developer" popups. Just download, drag to Applications, and go.
This fork aims to:
- ✅ Provide signed and notarized builds that work out of the box
- 🔧 Keep the app working on the latest macOS releases
- 🐛 Fix outstanding bugs and review community PRs
- 📦 Provide regular, up-to-date releases
- 🤝 Maintain an active open-source community around the project
SaneScroll intercepts scroll events and lets you configure scroll behavior per device type. Keep "Natural" scrolling on your trackpad while using traditional scroll direction on your mouse — or any combination you prefer.
- 🔄 Invert scroll direction for physical scroll wheels independently from trackpad
- 🚫 Disable scroll acceleration for mice
- 📏 Adjust scroll distance (line-by-line or custom multiplier)
- 🎯 Per-device configuration
- 🚀 Launch at login
- 📌 Lives in your menu bar, out of the way
- Download the latest
.dmgfrom the Releases page. - Mount it and drag SaneScroll.app to your Applications folder.
- Open SaneScroll. You'll be prompted to grant Accessibility permissions — this is required to intercept and modify scroll events.
🔒 All releases are signed with an Apple Developer ID certificate and notarized by Apple, so macOS will not display any security warnings.
SaneScroll lives in your menu bar. Click the icon to access preferences.
If you've hidden the menu bar icon, simply open the app again (e.g. from Spotlight or Applications) to bring up the preferences window.
Requires Xcode 16+ and macOS 12.3+.
