So I found out about this recently as well, but touch events are not sent to QQuickItems on macOS by default, because QNativeGestures are sent instead, due to receiving high-precision gestures from the OS itself.
To receive touch events you need to use private API at the moment. Have a look at the implementation of void QQuickMultiPointTouchArea::setTouchEventsEnabled(bool enable) You would need to get the relevant function pointer and call registerTouchWindow on your custom QQuickItem.
