I’m glad unclicking “tap to click” works for some, but it has no effect for me. I think it’s simply a matter of keeping my palms off of the trackpad; if I touch it while typing, the cursor jumps all over the screen, with various forms of unsettling results. It’s most annoying having to keep my hands lifted up off the computer. Not sure if it’s helping with my carpal tunnel either. Update (09/04/2020): Go to the App Store and find the “False Tap Stop” app. This fixed the problem for me and others. Try it. Hope you have the same success.
