Yep. Pretty much all nerd solutions to physical or legal threats are genius but also worse than useless. Here's a $5 hammer, hit him with it until he gives us what we're looking for, so goes the comic I saw once.

That’s why it needs to be destructive. You can’t beat access to something out of someone if it has been deleted.

While true, they may beat you anyway just to be sure.

Or, maybe just add back the Kensington Security Slot and attach the laptop to yourself/desk with a strong wire and not have your laptop yanked in the first place. I understand the first part of my idea is dead in the water, we hardly get additional ports, let alone a slot hardly anyone will use. But I would like to see a way to retrofit a KSS on a laptop.

Yeah I still don't get this. I hate that I can't secure a Macbook. But pretty much every cheap laptop comes with a kensington lock hole.

Sure it is not _super_ secure but being able to leave my laptop for 1 minute in a public place is nice. Instead I have to put the macbook in my backpack and take it with me.

Feel like this something similar can be accomplished for Macs using AirTags/Apple Watch proximity to do specific actions via Shortcuts App, instead of just locking/erasing remotely using 'Find My'.

macOS Monterey added a "Erase All Content and Settings" feature that works like the iOS versions by deleting the encryption key, although as a result the feature only works on T2 and M1 Macs which encrypt the data at rest even without FileVault.

It wouldn't surprise me if Apple imports more emergency wipe features into macOS from iOS.

The problem is, if they are serious and suspect you might be prepared and technical savvy, they will never allow you to operate the device.

You are probably thinking of the $5 wrench in https://xkcd.com/538/

Instead of a personal key combo, a dongle with an OTP code. Both the dongle and the computer have accelerometer-bump-tilt-oh-fuck-support. A OTP has to be entered every 5 minutes, or a secure screen/dead sequence starts. Sudden accelerated movements or a lack of presence-detection would also start the sequence.

I once wrote a script to automatically lock my computer if I got too far away from it, back when I was wearing a bluetooth wristband. I guess you could do the same, but shut down the computer instead.

Unfortunately, iOS-provided location resolution for use in shortcuts makes it worthless for in-home use. Unless you live in a mansion though I guess.

Actually we know it wouldn't. The agents arresting him did in such a way that they prevented him from touching his laptop (by creating a diversion), because they were feared that such a protection might exist.

If done properly the agents grabbing his laptop/snatching it away from him would have severed the power connection to the battery-remove laptop locking it permanently.

That's referred to as rubber hose cryptography.
