Magic Trackpad and Multi-Touch Trackpad Update 1.0 includes the required software to use and configure Magic Trackpad in Mac OS X v10.6.4. The update also installs the three-finger drag gesture and inertial scrolling for certain Mac portable computers, as listed below.

It's important to run Software Update after you've successfully paired Magic Trackpad by clicking on the Apple () menu and choosing Software Update. Magic Trackpad and Multi-Touch Trackpad Update 1.0 will appear in Software Update only after you install the Mac OS X v10.6.4 update and after you pair your Magic Trackpad. You can pair Magic Trackpad by clicking the Bluetooth menu bar icon, choosing "Setup Bluetooth Device…" and completing the onscreen instructions using Bluetooth Setup Assistant.
If you have a supported Mac portable (as listed below) that has Mac OS X v10.6.4 installed, install this update by using Software Update or by downloading the manual update to add inertial scrolling and three-finger drag gesture support.
