alt Hacker NewsHow beneficial is this versus just being theater? The example used in this is the government accessing the reporters laptop via biometrics.
But in this case, and especially under this admin legal or not this app won't stop them, unless I'm misunderstanding the macOS security model. Even with FDE enabled, sending it to the lock screen with biometrics disabled will not do anything to stop them from being able to access the contents of the hard drive via forensic methods with relative ease.
I think that at best this will only stop the casual person (i.e. a family member or roommate/random snooper)? In which case there would be no point to switch away from biometrics.
You're far better off just keeping more private information on the iPhone and isolating that data from a Mac, since that has far more resistance to intrusion in AFU mode than a Mac.
My interpretation was that it's easier to physically force someone to mash their finger on the sensor than to get them to divulge a password, not that it offers you any kind of legal protection. But yeah, it's a plausible but somewhat contrived situation to find yourself in.
