tap and drag force touch
Problem when you force click to drag an item it wears all the oil off your finger tip and increases friction making it difficult to drag items or highlight text or whatever used to require two taps and a drag. Solution:
Go to prefreences
go to accessibility
on the left pane go down to mouse & trackpad
click on trackpad options
Now click on the enable dragging box. You can also select wheather to enable without drag lock or with drag lock.
Without Drag Lock, dragging stops immediately after you lift your finger after dragging. With Drag Lock, dragging continues even if you lift finger and one tap on the trackpad is required to stop.
