What to do if an optical mouse pointer moves slowly or doesn‘t move

Apple Pro Mouse, Apple Wireless Mouse, and Apple Pro Mouse (2003) are all optical mice. These mice detect movement using an optical sensor on the bottom instead of a ball. An optical sensor needs a surface that has some texture to work effectively. This is because changes in surface texture provide reference points that the optical sensor uses to detect movement, which is translated to pointer movement on the screen.

• Check the Mouse Tracking setting in the Mouse control panel. For more information see article 58651 "Apple Pro Mouse: Optimal Setting in Mouse Control Panel".
• Make sure the mouse is on a textured surface such as a table top, or a mouse pad that is a solid color.

The Apple Pro mouse does not work on these surfaces:

• glass, mirrored surfaces, or other glossy materials
• half-tone images, such as mouse pads with pictures
