This would be perfect if it could monitor the force with which the lid is closed (macs have accelerometers after all, either this info or an acceptable proxy could be derived?). Gently close? no action. Stronger, faster action? Disable touch ID Slam shut in full panic? yeah disable all biometrics, lose all state, even wipe the ram and the filevault key if it's an option

You must not have cats or children if you think that last one is reasonable

Perfect rage quitting machine. There should be an enterprise version: when lid is closed with full force it also sends a professional resignation letter to the current employer.

Ok just unload the filevault key from ram, better? And if possible tell the secure enclave to revert to the before-first-unlock state

I'm surprised Apple doesn't offer an option. On the iPhone you could do this by pressing the power button several times. Not sure if this still works because the iPhone 6 was my last one though.

Pressing and holding Power + Vol Up/Down is the current combo

If the threat model includes state-level actors, then disabling biometrics won't prevent data from being retrieved from physical memory. It would probably be wiser to enable disk encryption and have a panic button that powers down/hibernates the computer so that no unencrypted data remains on RAM.

The website says shutdown "takes time" and "kills your session" but a hibernation button would take effect just as fast and would preserve the session.

a cop works for "the state," but he's definitely not a "state-level actor."

Apple Silicon is at least much more difficult to attack in this way, though it might be possible.
