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,

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.

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.
Added Hungarian and Polish translations. (Thanks, Léki and Artur.)
Added a debug console to help with fault-finding. To show the debug window, option-click (⌥-click) the Scroll Reverser menu bar icon.
