Scroll Reverser

Scroll Reverser is a free app for Mac OS X that reverses the direction of scrolling. You can use it with OS X Tiger, Leopard and Snow Leopard to make your scrolling match the 'natural scrolling' in Lion.

On OS X Lion, use it to customise scrolling behaviour beyond what is possible in system preferences, for example to reverse the mouse but not the trackpad. It is also useful for getting Wacom tablets to scroll properly on Lion.

FAQ / Troubleshooting

Does it reverse 3-finger swipes too? No, it only reverses scrolling. The other gestures are a lot more complicated, and I won't be able to add support for them.

Sometimes it reverses my mouse scrolling, even though "Reverse Mouse" is off. Is there a bug? Check if you have any fingers touching the trackpad. When two or more fingers are on the trackpad, Scroll Reverser thinks you are scrolling with the trackpad.

I reverses my trackpad scrolling, but "Reverse Trackpad" is off. Is there a bug? If you have an older Mac without a multi-touch trackpad then Scroll Reverser will see your trackpad as a mouse.

The three finger tap gesture in Lion that does a dictionary lookup no longer functions when Scroll Reverser is active. Yep, sorry. I know about this. I haven't worked out a fix yet.

I want to reverse scrolling on my Windows machines too. AutoHotKey (free, open source) has the ability to reverse scrolling on Windows, and here's a guide to configuring it.
