How to use the Force Touch trackpad on your Mac?

The Force Touch trackpad lets you Force click by pressing on the trackpad and then applying more pressure. This allows you to take advantage of added functionality in many apps and system features on your Mac. Whereas in a Multi-touch trackpad which is a glass surface physically pushed down to be detected by magnets, resulting in a click. It can also sense movement. It can sense several movements at once, hence the name.

A touch surface that does not physically move when pushed. Instead, the entire surface is basically a touch screen without the screen, and electromagnets are used to simulate a click feel when pressing. It can also track multiple movements and can sense how much pressure is applied to a click.

Here are a few of the advantages of force touch:

• Pressure sensitivity
• The entire surface can be pressed (a size limitation of a physical trackpad means that the very top won’t be able to detect clicks).
• The option of much bigger trackpads (again, there are physical limits to how big a traditional trackpad can be).
• The trackpad’s clucking mechanism does not wear over time, so they feel will remain as good for the entire lifecycle of the device.
• It allows you to get quick access to certain things and set up much more customization in the workflow you desire.

To see a video of a Force click, choose Apple menu > System Preferences. Then choose Trackpad, click the Point & Click tab, and hover the pointer over the Look up & data detectors checkbox.
