- Great idea and implementation! If you are hesitant to install this for any reason, you can accomplish the same thing with this one liner:
sudo bioutil -ws -u 0; sleep 1; sudo bioutil -ws -u 1
Edit: here's a shortcut to run the above and then lock your screen. You can give it a global keyboard shortcut in the Shortcuts app.

- Can you get TouchID to register multiple fingers and script the actions; maybe your middle finger unlocks touchID, but your index finger disables touchID until you enter your password.

- The iOS equivalent is to hold the side + volume button until the power slider shows up. Cancel out of it and the next unlock will require your passcode. Pressing the side button 5x triggers Emergency SOS which does the same thing. Been there forever but barely anyone knows about it.
Nice to see something like this on the Mac side.

- An opportune time to mention the real-world example of when the authorities really wanted to gain full access to a computer but did not want to resort to legal compulsion or "rubber-hose cryptanalysis" -- they simply waited until the target was logged in, staged an altercation in the immediate vicinity, and then snatched the open laptop away from them.
You can read about the sting, here:

- Neat idea.
I remember way back in the day, there was some question as to the legality of compelled unlocking of devices; IIRC, it’s been deemed legal to compel a fingerprint, but illegal (under the first amendment?) to compel entry of a password—IIRC, as long as that password hasn’t been written down anywhere.
I gather this is written to that end primarily? Or is there some other goal as well?

- This is great. I see many times "security advice" against biometrics replacing password unlock, but most of the time I am more worried about getting recorded by somebody/something while typing a password in the open than anything else. This makes it better for those other cases.

- Maybe clicking the Touch ID button could invalidate the login attempt and ask for password?
I like logging in with my finger print, but I would like an “out” in the same vein as this.
- 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
- > in sensitive situations, law enforcement and border agents in many countries can compel a biometric unlock in ways they cannot with a password.
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.
- How 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.
- I think the thing that really surprises me is that Washington Post reporters are using Apple products and not just a Linux distribution. They are professionals. At some point, Apple can be compelled to work against you, but Linux is just a product off the shelf.

- If this were a concern for me the better choice is shutting down the laptop to encrypt the drive and disable biometrics. This does nothing since the drive is still unencrypted.
- This makes me wonder how I can do the reverse — I'd like to always use touch ID and never ever be asked for password except when it's technically necessary, e.g. after a reboot. In effect, I'd like to completely remove this time component from biometric authentication.
- 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.
- INAL, but if the authorities had captured your device with touchID enabled and legally ask you to use it to login and you do an action that would disable touchID, then that would be "obstruction".

- >That’s not just one leak investigation—it’s access to a reporter’s complete source network, enabled by biometric convenience features.
Really nice to see that everything is AI generated now!

- This is dope OP, well done. Terrific solution on something that Apple clearly missed.
- I would love to have a mode that I must use my long password to unlock my mac for security purposes. But when unlocked, use touchid as an alternative to my password for convenience.
So just the normal TouchID mode but not for unlocking the mac.
- This is awesome, thank you. Was just thinking about this problem the other day. Glad someone whipped something up.
- The 2026 version of "Boss Key".
- What's the rationale? It should be described in the README.md IMO
- > No command injection — Timeout parameter is a Swift Int, not a string
Please don't use slop machines to write READMEs. If you're launching bioutil as a subprocess, you're passing the timeout as a string. In your code, you read the timeout, convert to int, set timeout to 1, and set it back to the previously retrieved value. There is no difference between keeping it as strings or doing a string->int->string round-trip, assuming no sizing and formatting weirdness.

- Honestly I’m surprised this wasn’t already a feature in macOS. Thank you for coding it and publishing as open-source!

- This should be an OS X feature, it's just that good.
Great work, congrats!

- PSA to iOS users: if you tap the lock button 5x it forces password-only unlocking. Useful at protests or any precarious situations with law enforcement.
- There should just be a way to setup an alternate dummy account based on the finger you use. This gives the illusion of compliance but your real data is safe.
- Why not just disable touchID if the Bluetooth modem hears advertising packets from the 00:25:DF OUI?
- very nice thought
- If someone can force you to use touch id they can probably also force you to enter your password.
(If you’re about to comment about fingerprints on transparency film and balloons filled with warm water then yes good point)
