Password prompt misses to register some characters in MacOS Sequoia 15.2

I and a colleague have been getting issues when unlocking our screens in MacOS Sequoia after the 15.2 update, with the password prompt sometimes, around 50% of the time, reporting our passwords being wrong. I first thought the passwords to be corrupted in some way and I made a password reset on my computer by booting into Recovery like some have suggested on this forum. However, in this case that did not help.


Then my colleague discovered something interesting! When typing his password into the password prompt some characters are not always being registered the first time you press the key and thus have to be pressed twice! This turned out to be the case also for me. On my Mac when this happens it is always the same character that has to be pressed twice to register, but in the case of my colleague there have been two different characters with this problem. The problem is not only present in the screen-unlock prompt by the way, it even goes for the password prompt MacOS pops up when logging in to this forum.


Worth noting is that we have zero issues with our keyboards outside of the password prompts! Also, my colleague typically enters his password using the built-in keyboard of his M2 MacBook Air and I do it using a Magic Keyboard (the one before Touch ID) wirelessly connected to my M4 Pro MacBook Pro while in clamshell mode.

MacBook Pro 14″, macOS 15.2

Ah, excellent comment! On my own computer I experience this issue both when using the built-in keyboard and when using my external Magic Keyboard with the computer in clamshell mode. The Magic Keyboard can be wirelessly connected or connected using a lightning cable, the issue still persists.

Restart in Safe Mode.


This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts.


The boot up will be slow and can take some time - Normal.


Safe Mode will also eliminate Third Party Software, extensions and drivers from loading.


It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 


Does the issue present in this mode ?


Sometimes a Safe Boot followed by a Normal Boot will just put things right.

Do you know if your colleague also has a problem with q, or whether you have a problem with his problem characters?


There is at least one of his problem characters which I have not encountered any problems with (yet). Btw, I can now report I have also triggered this problem with the "v" character on my computer.


My colleague claims he has seen changes in the behavior, i.e. changes in which character is problematic. We have not had a lot of research time though.

I'm experiencing the same issue on a 2021 MacBook Pro at least since I moved to 15.2. It seems to happen with the first or second password character. Subsequent occurrences of the same character seems not affected. I have to type the affected character twice in order to get it right. In my case the affected characters are 3 and b.

15.3 didn't solve it. In fact it may have even gotten worse given that now it might happen on both the first and second character during the same attempt.

This is really scary because it raises the suspicion that there is some kind of keylogger active.

I've been having this problem for a little while now. When logging in, the first character will not type. I use the built-in keyboard on my Macbook Air. Oddly, I just tried it again, then went to log into this site, which sent me a code to enter which happened to have the same character in it as the first one of my password and IT did not type the first time I tried to enter it either. I had thought that the problem was just because it was the first character in my password, but that was not where it was in the code. (If that makes any sense) This is for sure annoying.

@ Tom G.- Interesting you should ask about those specific letters & numbers - "789uiojklm ". Can you explain briefly why you asked? I wonder because on my brand new Macbook Air 13" M3 those exact keys didn't type out at all and I had to return it. It came installed with Sonoma and I had only updated (not upgraded to Sequoia). This was using my 2021 Apple magic keyboard, which works fine. I then bought another (Macbook Air 13" M3) replacement and it came with Sequoia and I've had no keyboard/typing problem. Anyway, it was curious to me that the numbers & letters are all vertically in the same area on the keyboard.

There is definitely something weird about this - do any1 of you who has this problem, have by any chance changed the default wallpaper photo - the one on desktop that also appears on login screen? Somehow I noticed that once I changed from default live wallpaper to my usual still photo that I used for years now, the wakeup from display sleep and login prompt started being very very sluggish. I kind of began to correlate this to missing keystrokes. Now, this wouldn't be so suspicious if my wallpaper didn't somehow reset to default one (not really sure what caused it, could be update to 15.3.1 but it wouldn't actually make sense) and ever since, I did not have either missed keystrokes, or sluggish login window.

(confused).

To me, this could be indicative of a possible hardware issue with the builtin keyboard


How I arrive at this is simple


Until the entire operating system is fully loaded


That would have only occur, after, you have successfully logged into the computer


So, conclusion would be, Not the Operating System in and of itself, but points elsewhere

Is it mathematically possible for a singular key on a built-in keyboard, wired or Bluetooth-connected Apple Keyboard, and various third-party USB keyboards to malfunction simultaneously?

That actually made me laugh out loud. :-)


Have now changed language settings to a potentially more common Swedish/Swedish, but this did not remove the issue.


If I can collect enough inspiration I will start to cycle through passwords until I can find som kind of pattern. I cannot promise it though. Sounds like a pain.
