Unity in Mac OS X trackpad clicking count problem.
I'm using apple trackpad on OS X Catalina. The Unity version is the 2019.4.3f1 Personal.
When I click some editor button (for example the "Auto generate lighting" at the lower right corner), the corresponding window will open when I pressed down the trackpad, then close immediately if I release the press. This phenomenon sometime can also occur on editor drop menu, image-color or other editor elements. In those scenarios, I have to double click (quick press-release, press-release actions) the trackpad to correctly open the corresponding window.
The trackpad is working well in any other applications, the OS X system is freshly installed, and I tried to toggle "Tap to click", "Force Click and haptic feedback" options in the preferences pane but none of these efforts helped.
