For now there's only one way to assign Force Click actions on your Mac, and only one kind of action to assign.
Sure, that makes un-assigning Force Click the same as disabling it, but Force Touch and Force Click are brand new and Apple has only just begun experimenting with them. No doubt other functionality, and third party app implementations, will follow.
Note: Force Click is currently available on the 2015 MacBook and 2015 MacBooks Pro, and the new Magic Trackpad 2.
How to assign Force Click on the Mac
- Launch System Preferences.
- Click on Trackpad.
- Click on Look up & data selectors
- Set it to Force Click with one finger to use Force Click, or Tap with three fingers to disable Force Click.
If you later change your mind, simply perform the same steps again and switch to the other option.
