What is SmackMac (SlapMac)?

SmackMac is a macOS app that detects when you physically slap, tap, or hit your MacBook and responds with sound effects, screen cracks, haptic feedback, and more. It uses the built-in accelerometer — no hardware modifications needed. Often searched as SlapMac, Slap Mac, or Slap MacBook app.

Will slapping my MacBook damage it?

No. SmackMac only reads your MacBook's built-in accelerometer — the same sensor that protects your hard drive during drops. It doesn't modify any hardware or system files. A gentle tap is all you need.

Does SmackMac work on Intel Macs?

SmackMac requires Apple Silicon (M1 or later). Intel MacBooks use a different sensor architecture that doesn't support the accelerometer data needed for slap detection.
