- Among the many changes in Lion (Mac OS X 10.7), one of the most controversial is a new way of scrolling. In Lion, when you drag two fingers downward on a MacBook’s trackpad or Apple’s Magic.
- Download Flip Mouse Wheel - Use this tiny and clever app to reverse the scrolling direction so that your mouse wheel works just as your finger does on a touchscreen.
macOS 10.15 users: Scroll Reverser is currently NOT fully compatible with Catalina due to various issues with the new security and privacy settings. I am working on trying to get the bottom it but it has been a frustrating experience so far.
For Scroll Reverser to work you will need to have it enabled in both the Accessibility and Input Monitoring lists under System preferences → Security & Privacy → Privacy. Even then it might not work, for no apparent reason....

FAQ / Troubleshooting
It doesn't detect my trackpad. 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 Logitech external trackpads. I know of no fix.
Can you make it reverse 3- and 4-finger swipes 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.
Can you make it reverse scrolling on volume sliders? No, this is not possible.
Why is Start at Login not working? Start at Login may fail if Scroll Reverser is not in your /Applications folder.
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.

Best Scroll Reverser App Mac Pro
v1.7.5 (24 Apr 2017)
- Fixes the following problems:
- Presence of Scroll Reverser triggering additional security dialogs (for example, in Keychain permissions dialogs);
- 'Shake to locate cursor' not working with Trackpad while Scroll Reverser is running;
- Notification center getting stuck half-open while Scroll Reverser is running.
- Added Simplified Chinese (zh-CN) translation. (Thanks, Ruocheng Wang.)

v1.7.3 (7 Nov 2016)
- Scroll Reverser now silently relaunches itself when your Mac wakes from sleep. (This is because of the ongoing problem where macOS sometimes stops sending gesture events to Scroll Reverser after awaking from sleep, preventing it from telling the difference between trackpad and mouse. Hopefully, this will help.)

- Fixed a bug where, on unchecking 'Show in menu bar', the 'Icon Hidden' message would appear multiple times.
v1.7.2 (26 May 2015)

- You can now right-click (or control-click) the menu bar icon to toggle Scroll Reverser on/off.
- New algorithm to (hopefully) distinguish more accurately between trackpad and mouse.
- Added a debug console to help with fault-finding. To show the debug window, option-click (⌥-click) the Scroll Reverser menu bar icon.
