Knock: Knock on your MacBook to control your Mac

Knock turns taps on your MacBook into instant actions. Switch tabs, change desktops, play/pause music, open apps, run custom scripts, or take screenshots - all with a simple knock. Tap the desk beside your laptop or knock on the MacBook’s chassis (not the trackpad). Knock uses the built-in accelerometer in Apple Silicon MacBooks to trigger customizable shortcuts.

This is pretty fun! How do you prevent accidental knocks/bumps?

@gabe Thanks Gabe, really appreciate that.

Distinguishing intentional knocks from general vibration is actually the main challenge. Knock looks for short, sharp vibration spikes rather than longer or continuous movement, which helps separate a deliberate knock from things like background desk vibration.

It also temporarily ignores knock detection while you're typing. There’s a 500ms suppression window after the last keystroke so heavy typing doesn’t accidentally trigger gestures.

There’s also a live sensitivity slider and a Knock Test tool so users can tune it for their desk setup and see exactly what the accelerometer is picking up.

Right now Knock supports single, double and triple gestures, but I’m definitely exploring more custom patterns and timing options for future updates.

after using the cheat code came across this love the product

@sammy_xf Appreciate it! Glad you found it!
