"Rubber band" scrolling was recently instituted into the Mac OS in a recent upgrade, and comes by default on all Macs running the Lion OS. Apple has referred to it as "rubber band" scrolling, while others would describe it as "springy", "shaky", or just annoying. I personally found it annoying and so I decided to find a way to disable it, and I found quick fix. Follow these steps to disable/enable "rubber band" scrolling: 1. Click on the Apple apple button on the top left corner of your screen and then click on "System Preferences". 2. Under the top row of icons titled "Personal", click "Universal Access" on the far right. 3. At the top of the newly opened screen you have four options to click ("Seeing", "Hearing", "Keyboard", and "Mouse and Trackpad"). Select "Mouse and Trackpad". 4. Select "Trackpad Options..." towards the bottom of the newly opened screen. 5. In this screen, "Scrolling" should be checked unless you have tampered with this option before. To the right of scrolling is a drop down arrow with two options: "with inertia" or "without inertia". Select "with inertia" if you would like the "rubber band" effect or select "without inertia" if you would like to remove the "rubber band effect". 6. Select "Done" and enjoy your new method of scrolling! I hope this helped. I just figured this out today as the rubber band scrolling was getting annoying so I decided to make a small guide about it. Let me know if you need any additional help! Thanks.
