You can do a lot on your iMac using simple trackpad gestures—scroll through webpages, zoom in on documents, rotate photos, and more. With the Force Touch trackpad, pressure-sensing capabilities add another level of interactivity. The trackpad provides feedback—when you drag or rotate objects, you feel a subtle vibration when they’re aligned, allowing you to work with greater precision. For examples of force click options, see the Apple Support article System Settings, click Trackpad. In Trackpad settings you can:
Learn more about each gesture
Set the click pressure you prefer to use
Decide whether to use pressure-sensing features
Customize other trackpad features
Tip: If you’re force clicking when you don’t intend to, try adjusting the click pressure to a firmer setting in Trackpad settings. Or change the “Look up and data detectors” option from the “Force Click with one finger” default setting to “Tap with three fingers.”
