Password prompt misses to register some characters in MacOS Sequoia 15.2

Could you tell us what these characters are exactly? That's necessary for anyone to try to duplicate the problem and explore possible causes.

Also confirm that you are both using European ISO type keyboards (with a key between Z and left shift and a vertical enter key)?

I to am still laughing especially as we posted at the same time

Missing information from the get go will often lead to less that good trouble shooting

After all we are not Mind Readers , yet

Can you elaborate? This is something that I've suspected for a while, given how Apple is moving towards app extensions instead of launchd tasks. But I haven't had the time/opportunity to see a definitive case of a 3rd party system modification running in Safe Mode. Well, I think I have seen it - I just didn't have time to investigate and try to reproduce.

Just want to confirm flammit's description perfectly matches my experience.

Is this also the first report of this problem outside your location? I wonder if anything in common...

This is still happening. I have now had all of "asdf" not respond to the first keypress (second ones are fine) on one instance of the password lock screen only.

FWIW, I do use the remote link keyboard/mouse between my Macbooks, but the keypress issue occurs both on the remote keyboard and the local one when the password screen is "broken".

Can someone PLEASE fix this???

Thanks for that. I see you've been solving this dilemma for 3 years ... 15 pages of questions! The issue is ridiculous and unnecessary. You'd think Apple would figure out a better solution so as not to freak people out so much.

Silly mouse key setting! And why does it disable those keys ...

Upgraded to 15.3.2 and this is still happening. Can someone at Apple please fix this??? How can this be properly escalated?

Same symptoms as before (emptying the input makes the first presses for certain keys not work). I can provide a video of the symptoms if needed. The missing keypresses do extend to even after the unlock screen (in the first input box, but only once).

Same here.Sometimes it doesn't happen on the login screen, but it happens on the first keystroke just after login.

Hah. Not for long -- the missing first character is back after a few weeks. And now, something new and different! It's skipping the last character, not the first character. I was sure this had to be my own fault, but nope, it's happening repeatedly. Just on the password.

Can't say I like Sequoia much anyway - the moving 3d backgrounds make me nauseous. LOL

Couple of days ago, my background switched completely on its own to my custom background (!!!) while I was not at home during the weekend. And slugishness has started, missing keystrokes not yet but I do expect it.. :(

It's just a very obscure problem. I have several Macs here, three of them running Sequoia 15.2 and none with the problem you describe. And yours is the first post I've seen describing it.
