Here is how you can prove that haptic feedback is working on your new macbook pro.
Place one finger on the trackpad and apply slight pressure to initiate the first click, then increase pressure until you feel a second click. Then place 2 fingers on the trackpad and initiate first click, then increase pressure. You won't feel a second click. This indicates that obviously the click you feel is not a physical reaction of the trackpad but an electronic haptic feedback.
