Knock – Control your MacBook using taps detected by its accelerometer

Summary: Knock uses the built-in accelerometer in Apple Silicon MacBooks to detect taps on the laptop or desk, triggering customizable shortcuts like switching tabs, changing desktops, controlling media, opening apps, running scripts, or taking screenshots.

What it does

It detects taps on the MacBook chassis or nearby desk and converts them into instant actions via customizable shortcuts. A live “Knock Test” tool allows users to adjust sensitivity and monitor sensor input.

Who it's for

Users with Apple Silicon MacBooks who want to control their device through physical taps instead of traditional input methods.

Why it matters

It leverages the MacBook’s accelerometer to provide an alternative, hands-on way to execute commands without relying on keyboard or mouse input.
