Scroll Reverser is a Mac app that reverses the direction of scrolling, with independent settings for trackpads and mice (including Magic Mouse).

For wheel mouse users, Scroll Reverser also incorporates a step size control, which disables scroll acceleration and instead scrolls a fixed number of lines with each step of the wheel.

Scroll Reverser is free of charge and is made available under the Apache Licence 2.0, with source code on GitHub.

It is maintained by Nick Moore. To get in touch, contact support@pilotmoon.com, or head over to Scroll Reverser Discussions on GitHub. If you wish to make a voluntary donation you can do so via my new Buy Me a Coffee page. Please also check out my other apps.

Usage, FAQ & Troubleshooting

Uninstall. Scroll Reverser is a self-contained app and does not install itself deeply into your system. To completely uninstall, simply quit the app and move it to Trash. You may also want to delete the following:

Recommended settings. A common use case is to have natural scrolling for your trackpad and "classic" scrolling for your mouse. For this, enable natural scrolling in System Settings and configure Scroll Reverser with "Reverse trackpad" off and "Reverse mouse" on. Doing it the opposite way round will give you the scrolling you want but gestures may feel wrong.

Step size control. If Scroll Reverser detects non-continuous scrolling (typically from a wheel mouse), it will show a step size slider. The slider controls the number of lines scrolled with each step of the wheel. Set the slider all the way to the left to disable this feature and use the system default behaviour.

Can't enable Scroll Reverser. If Scroll Reverser does not respond when you try to check "Enable Scroll Reverser", please try the following:
1. Quit Scroll Reverser.
2. Ensure Scroll Reverser is located in your Applications folder.
3. Go to System Preferences → Security & Privacy → Privacy → Accessibility.
4. Use the "–" button to remove Scroll Reverser from the list; then add back with "+".
5. Now start Scroll Reverser. It ought to work this time.

Scroll Reverser sees my trackpad as a mouse. There's a system setting in Accessibility that lets you double-tap with three fingers to zoom. Unfortunately, when it is turned on, it stops Scroll Reverser working properly. Look for the checkbox: Accessibility → Zoom → Advanced → Controls → Use trackpad gesture to zoom, and make sure is is not checked (more information here).

Also, if you have an older Mac without a multi-touch trackpad (late 2007 and earlier) then Scroll Reverser will see your trackpad as a mouse. This also affects some third party external trackpads.

Can you make it reverse swipe gestures too? No, this is not possible. However, swipe direction respects the "Scroll Direction: Natural" setting in System Preferences. Set that to your liking, then use Scroll Reverser to adjust scrolling with respect to that base setting.

Scroll Reverser doesn't work in Apple's Calendar app. Calendar has a custom scrolling interface based on gestures, not scroll events. Scrolling with Magic Trackpad and Magic Mouse cannot be reversed in Calendar.

I am controlling a machine via remote desktop, and Scroll Reverser is running on both the local and remote machine. Anything I can do to make it work nicely? Run this command at terminal on the remote machine: defaults write com.pilotmoon.scroll-reverser ReverseOnlyRawInput -bool YES then quit and restart Scroll Reverser.

Thanks to all those who contributed - too many names now to keep track of in the release notes. (I am now using the CrowdIn translation platform for app localization. If you would like to update the translation in your language, here is the invite link: https://crwd.in/pilotmoon-apps. I can also add new languages, you will just need to send me a message first so I can add it.)
