Disable Inertia Scrolling in Mac OS X Lion
Flick down with two fingers on a trackpad or Magic Mouse in Mac OS X Lion and you’ll experience inertial scrolling, where after your finger has stopped moving the page continues to scroll in the intended direction until it slowly stops. This fluid and natural scrolling experience comes from the iOS world, and while it works quite well on the desktop, it’s not for everyone.
- Open System Preferences from the Apple menu
- Click on “Universal Access” and then click on “Mouse & Trackpad”
- Near the bottom, click on “Trackpad Options” button
- Next to the “Scrolling” checkbox, click so that “without inertia” is set then click “OK” and close out of System Preferences
Intertial scrolling is now off. Try to scroll now, and even if you flick your fingers the scrolling will end immediately when you lifted them from the trackpad, just like it’s 2005 again.
Note that in Mac OS X 10.6 Snow Leopard, intertial scrolling was called “scrolling with momentum” instead, and the option was contained within the standard Trackpad & Mouse preference panel.
