Scroll Reverser is a free Mac app that reverses the direction of scrolling, with independent settings for trackpads and mice.
Scroll Reverser was made by Nick Moore with language translations by other contributors. To get in touch, contact firstname.lastname@example.org, tweet @pilotmoon or heasd over to Scroll Reverser Discussions on GitHub. Please also check out my other apps.

FAQ / Troubleshooting
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.
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.
