Change the way your trackpad works
If you use a trackpad, there are several things you can do to change the way it works and responds. 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.
The options available depend on the Mac you’re using. For example, you can use three fingers to swipe only on some computers.
Choose Apple menu > System Preferences, then click Trackpad.
Select point and click options (depending on the Mac you’re using, you’ll see only some of these options):
Look up & data detectors: Select this option to quickly look up a word or do quick tasks with certain types of data, such as dates and addresses, then choose “Force click with one finger,” or “Tap with three fingers.”
Secondary click: Select the option, then choose “Click with two fingers,” “Click in bottom right corner,” or “Click in bottom left corner” to secondary (or Control) click items on your screen.
Tap to click: If you select this option, tapping the trackpad with one finger is the same as clicking.
Look up: Select this option so you can use three fingers to double-tap a word to look it up in the dictionary.
Tracking Speed: Drag the slider to set the tracking speed of the pointer when you move it across the screen.
Silent clicking: Select this option to turn off the clicking sound on a Force Touch trackpad.
Force click and haptic feedback: On a Force Touch trackpad, force click an item to take action. (To force click, press firmly until you feel a deeper click.) For example, force click a file in the Finder to show it in a Quick Look window. With the checkbox selected, you also feel tactile feedback when aligning objects in some apps, like Preview.
Select scroll and zoom options (depending on the Mac you’re using, you see only some of these options):
Scroll direction: Natural: Select this option to move the contents of a window the same direction as your fingers.
Zoom in or out: Select this option to pinch two fingers closed to zoom in, or pinch two fingers open to zoom out.
Smart zoom: Select this option to double-tap with two fingers to zoom in or out.
Rotate: Select this option to use two fingers to rotate items on your screen.
Select more gestures (depending on the Mac you’re using, you see only some of these options):
Swipe between pages: Select this option, then choose “Scroll left or right with two fingers,” “Swipe with three fingers,” or “Swipe with two or three fingers” to move between pages in a document.
Swipe between full-screen apps: Select this option, then choose “Swipe left or right with three fingers” or “Swipe left or right with four fingers” to move between apps in full screen.
Notification Center: Select this option to swipe left from the right edge of the trackpad to show Notification Center.
Mission Control: Select this option, then choose “Swipe up with three fingers” or “Swipe up with four fingers” to enter Mission Control.
App Exposé: Select this option, then choose “Swipe down with three fingers” or “Swipe down with four fingers” to use Exposé.
