switch off touchpad click sound
I am working on MacBook Air 13 inch 2017 running Mac OS Catalina 10.15.4.
How can I disable the click sound of the Touch Bar?
Standard Apple support instructions tell me that in the system preferences window left hand side underneath the 3 basic dialog boxes there is a ruler to switch it off. However on my system preferences this function is not present:
