Palm Resting on Trackpad Issue While Typing in MacBook 2016

Simply run this command in your terminal to fix the annoying palm rejection issue on the MacBook 2016. If you're a touch typist, you've probably noticed that the massive trackpad on the 2016 MacBook Pro picks up accidental palm touches while typing, causing your cursor to jump around or click in random places.

The Fix

Open Terminal and run:

defaults write com.apple.AppleMultitouchTrackpad TrackpadThreeFingerDrag -bool false
defaults write NSGlobalDomain com.apple.trackpad.scaling -float 0.6875

Then log out and log back in for the changes to take effect.

Additional Tips

If the above doesn't fully resolve the issue, you can also try adjusting the tracking speed in System Preferences > Trackpad. Setting the tracking speed one notch lower than your current setting can help reduce accidental palm inputs.

Apple's palm rejection algorithm improves with macOS updates, so keeping your system up to date is also important. The issue was most pronounced on early macOS Sierra builds but improved significantly with subsequent updates.

For the most aggressive fix, you can disable "Tap to Click" entirely in Trackpad preferences and rely only on physical clicks. This eliminates almost all accidental palm touches, though some users find it less convenient for everyday use.
