If you have an Intel-based Mac and there’s a PC application you need to use, you can run it using Boot Camp. You'll need to provide a copy of Microsoft Windows, but Boot Camp is included in Mac OS X Leopard. Setup is simple and straightforward — just as you’d expect with a Mac.

This update addresses issues with the Apple trackpad and turns off the red digital audio port LED on laptop computers when it is not being used. It also includes support for the Apple Magic mouse and wireless keyboard. It is intended only for use with Microsoft Windows XP and Microsoft Windows Vista running on a Mac computer using Boot Camp.

Requirements

Boot Camp 2.1 must be installed prior to running this update
For Windows Vista, Windows Vista Service Pack 2 must be installed before running this update.
