Sometimes, when I'm using my macbook,
Zoom in and out suddenly stops working.
Smart zoom also stops working. Restarting
killall -KILL hidd) does not solve the problem. The only thing that works is to go into
System Preferences, uncheck
Zoom in and out, wait a few seconds, and then check it again.
What processes are responsible for the trackpad? Is there a terminal command I can use to reset the trackpad system?
