An app that reacts when you smack your MacBook.
Lives in your menu bar. Watches the accelerometer, the microphone, and your AirPods. When anything feels like a smack, it reacts: plays a sound, flashes a face, pulses the keyboard LED, fires a notification. The face has range. The sounds have opinions. The Direct build's notifications have no shame.
Past the badges: features, architecture, privacy receipts, install, the moans. All on the project site so this README stays short.
| What it does | Features, screenshots, two-builds rationale. |
| Architecture | Module graph, detection gates, the path from IOKit to speakers. |
| How seriously tested | Mutation catalog, fuzz layers, host-app lane, pre-push gate. None of it proves the laptop flinches when you smack it. That part you verify yourself. |
| Support / FAQ | "How do I tune it." "Why won't the accelerometer wake up on App Store." Answers. |
| Privacy | Nothing leaves your Mac. Nothing. The page says it again with feeling. |
| Install | Download the DMG, drag the app over, done. App Store sandbox needs the sensor-kickstart helper once per machine. |
| CHANGELOG | Every release, what changed, why. |
# Direct build (notarized, drag-and-drop)
open https://github.com/Studnicky/yamete/releases/latest
# Or build it yourself
git clone https://github.com/Studnicky/yamete.git
cd yamete && make installApple Silicon MacBooks ship with a real BMI286 accelerometer (same chip class as the one in your phone) and Apple flags every line of CMMotionManager as API_UNAVAILABLE(macos). That sounded bratty to me. I touched it anyway. Full context on the project site.
If you use this daily I want to know what's wrong with you. If you install it, laugh once, and delete it, that's the right outcome and I'm glad you stopped by.
Stands on people who already did the reverse-engineering Apple wouldn't:
- KBPulse. Keyboard brightness via CoreBrightness on M1+.
- spank. IOKit patterns and hardware-interaction approaches.
- apple-silicon-accelerometer. Proved the BMI286 was accessible.
- mac-hardware-toys. Keyboard-brightness wrapping, system-level integration patterns.
- macbook-lighter. Brightness-daemon design, light-sensing approaches.
This app only exists because they did the work first. Pay them attention.
