Some of my macbook trackpad gestures are not working, such as open the launchpad using 4 fingers; show the desktop; and enlarge images using 2 finger pinch. I’m sure all of those functions are enabled in the system preference.
Other gestures are working normally, such as to swipe between applications using 3 fingers; go back and forth in browsers using 2 fingers, etc.
I guess it’s those gestures requiring using the “pinch” action are not working and everything else seem to be fine. Could you please tell me how to fix this problem? Many thanks!
