I'm currently running OS X Yosemite 10.10.5 on a mid-2015 MacBook Pro. I have tap to click enabled and have enabled dragging without drag lock. Currently I am able to double-tap to start dragging, and then the drag stops when I raise my finger. I want to be able to also end the drag by clicking, so the full sequence would look like tap-tap-drag-click instead of tap-tap-drag-release. I can do this on my 2011 Macbook Air, also running Yosemite. It feels really unnatural to me to have the drag continue after clicking down, and I keep intending to end the drag this way habitually. Do I need to break my habit or is this possible?
