About the "Ignoring trackpad when mouse is present" option on computers with a Multi-Touch trackpad

Summary

Are you trying to locate the "Ignore trackpad when mouse is present" trackpad option on the Trackpad tab in Keyboard & Mouse System Preferences, or—if using Mac OS X v10.5.6 or later—the Trackpad System Preferences on your MacBook, MacBook Pro, or MacBook Air computer with a Multi-Touch trackpad?

Products Affected

Mac OS X 10.5, Mac OS X 10.6, Portable Computers

To allow full use of gestures on the Multi-Touch trackpad even when a mouse is connected, the "Ignore trackpad when mouse is present" trackpad option no longer appears in System Preferences with Mac OS X v10.5.6 and later.

On MacBook, MacBook Pro, and MacBook Air computers with Multi-Touch trackpads running Mac OS X v10.6 Snow Leopard, the option to enable or disable "Ignore trackpad when mouse is present" is in the Mouse & Trackpad tab in the Universal Access System Preferences pane.
