Touch ID unlocks and locks instantly

Because you’re not going to want the touchID sensor constantly drawing power why the system is asleep. Just like an iPhone you have to wake the phone before touchID works.

And thats why pressing that button in a locked state to unlock it would be the only logic choice.

It works just like the iPhone, press the button to wake the device then “touch” to unlock.

On an iPhone i could just single press the Touch ID button to wake and unlock the phone. What you are writing makes as little sense as the actual implementation of Touch ID on the MacBook.
