Question: trackpad don't work correctly "dragging stops immediately when you lift your finger"
When I left my finger... dragging are continue. To stop dragging I must to wait few seconds after I left my finger. This is a bug of OS (all MacBooks works exactly). This is not a problem of my laptop.
I have MacBook Air 13 2015 (MacOs 10.13.1). I see this problem from my 1st Mac with OS 10.9 and I this is my third MacBook.
MacBook Air, macOS High Sierra (10.13.1)
