tl;dr
Mac Studio Contact ID works for every part apart from waking the machine after the keyboard has been switched off. MacBook Professional Contact ID works for waking from sleep. How can this be, and the way can I repair it?
Longer model
I’ve two Macs working Sonoma: a MacBook Professional (M1 2020), and a Mac Studio (M1 Max 2022) with a wi-fi Apple Keyboard with Contact ID.
I’ve biometrics (fingerprints) arrange on each machines, and I can use my fingerprint to auto-fill passwords in Safari, use Apple Pay, and many others., on each machines. I also can use my fingerprint to unlock the display screen if it has been locked, whether or not resulting from inactivity or manually, and if the machine has been in sleep mode for a brief time period.
The annoyance I’m going through seems when the machine has been in sleep mode for a while – I don’t know precisely how lengthy, however about 15–20 minutes appears to be sufficient, maybe much less. Edit: It appears maybe it’s not (solely?) the size of time, however (additionally?) whether or not the keyboard has been switched off. If I put the Mac Studio to sleep, swap the keyboard off after which on once more after 20 seconds and wake the pc up, the problem seems.
I put the MacBook Professional to sleep by closing the lid; I put the Mac Studio to sleep by urgent the Contact ID after which Escape.
After I open the MacBook Professional after a interval of sleep mode, I can nonetheless unlock it utilizing my fingerprint: I see a lock display screen with the textual content “Contact ID or Enter Password” and no password enter discipline (similar as if I simply lock the display screen). As soon as per week or so, it’ll ask me for my password with a password enter discipline and a textual content saying “Password required to allow Contact ID” (or phrases to that impact), however the remainder of the time, I simply put my finger to the Contact ID and it instantly unlocks.
Nonetheless, after I open my Mac Studio after a interval of sleep and/or after having switched off the keyboard, it requires a password each time. I get a lock display screen with a password enter discipline and phrases to the impact of “Enter password to unlock your Mac” – and Contact ID does nothing.
If I hit Escape (to place the pc again in sleep mode) after which wake it up once more, Contact ID as soon as once more works.
The System Preferences settings for Lock Display screen and Contact ID & Password are equivalent on the 2 machines (other than the variety of minutes earlier than the show turns off and the additional battery-based one on the MBP) – right here from the Mac Studio:
Notably, Use Contact ID to unlock your Mac is enabled, and as talked about, unlocking from the display screen saver/locked display screen works as anticipated; it’s solely unlocking from sleep mode that doesn’t work.
What could also be inflicting the Mac Studio to disregard this setting solely after a time period in sleep mode or after the keyboard has been switched off? Is there a technique to repair it so it really works the identical as on the MacBook Professional?
Edit: I simply had a thought that I attempted out. The distinction
