Probably not from a gentle slap, but we're not lawyers. Apple's warranty covers manufacturing defects, not user-inflicted slap trauma. Slap responsibly.
No. SlapBack requires an Apple Silicon (M1+) MacBook with a built-in accelerometer. Intel Macs don't have this sensor.
Yes! Select "Custom" mode and point it to a folder with your MP3 files. Your MacBook will play random clips from that folder when slapped.
Minimal impact. SlapBack uses the hardware accelerometer which is extremely power-efficient. You won't notice any difference in battery life.
Not if your sensitivity is set correctly. The default threshold filters out typing and trackpad use. Only deliberate slaps should trigger it.
The accelerometer sensor requires root privileges to read via IOKit HID. SlapBack will ask for your password once when you click Start. This is standard for hardware sensor access on macOS.
No. Windows laptops don't have the same accelerometer hardware. SlapBack is Mac-only, forever.
