Scroll Reverser is a free app for OS X that reverses the direction of scrolling. You can use it with OS X 10.5 and OS X 10.6 to make your scrolling match the 'natural scrolling' in OS X 10.7.
You can also use it with OS X 10.7 to customise scrolling behaviour beyond what is possible in system preferences, for example to reverse the trackpad but not the mouse.
Scroll Reverser is small, simple and efficient and works with all mice and trackpads with a scroll wheel or scroll gesture support, including MacBook trackpads, Magic Trackpad, Magic Mouse, and Mighty Mouse.
- Fixes for bug where Scroll Reverser would sometimes stop working, requiring app restart. (Now it should hopefully not stop working, and if it does you can just toggle Scroll Reverser off/on to reset it.)
- 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
- OS X 10.7 or later
