Tap That Mac: Double-Tap Your MacBook to Control It
A macOS app that reads the MacBook's built-in motion sensor, so two quick taps on the desk can lock the screen, play or pause music, or skip a track.

# how_it_was_made
Tap That Mac is for people who work at a MacBook and want a quick physical shortcut without reaching for the keyboard. I set the goal and the rules: two taps trigger one action, and a calibration step tunes detection. Claude Code handled most of the Swift implementation, the calibration pipeline, the packaging scripts, and the one-line installer. I made the calls on how the detector should behave when the desk wobbles, and kept the changes that held up.
