Change the way your trackpad works
If you use a trackpad, you can change the way it works and responds in several ways. For example, you can change how fast the onscreen pointer moves when you move your finger across the trackpad and customize the gestures you use with your trackpad so it works the way you want.
The options available to you depend on the computer you’re using. For example, you can use three fingers to swipe only on some computers.
Choose Apple menu > System Preferences, and then click Trackpad.
