When updating the OS to MacOS Sonoma, the system does not recognize the login and password

I've removed other users on my mac. That worked for a few weeks. However, the issue came back and I'd have to reboot the mac in this same way to present me with the username and password field just to be able to login again. It's really annoying.

Hello!!! I don`t know what happened, but I lost the admin account and now, even with all the account names and passwords, I´m not able to change anything or even to download a software...all after Sonoma...

Any help???

Thanks, and sorry about my English.

Best regards!

No passwords worked for me so I typed in the answer to one of my security questions saved with Apple and it worked. There is something seriously messed up with apples software. My suggestion to you is to instead of passwords you think they may want, there are 2-3 security questions you filed out a while ago. Try those answers. As messed up as this is, mine worked. Now I am stuck at another level. This is crazy. I have a new air mac 2 that I may have used for 40hrs so far in its life. I probably have to go to see a “genius” at a store to ultimately fix this problem. What a pain in my ***

Here is a list of possible cures to help you out.

If you forgot your Mac login password:

If you encrypted your Mac’s boot disk with FileVault 2:

This prevents you from using your Apple ID to reset your password (since the password is used in FileVault’s encryption).

I'm having the same problem every time I turn on the computer after a shut down or a restart. In my case I use two keyboard profiles: US and Latin American. My default keyboard is US but for reasons unknown, every time I restart, the keyboard in the login screen appears as Latin America. I changed the keyboard to US and the login worked. But every time I restart I need to change the keyboard profile in the login screen.

Having same issue, but all the logins on my work mac use my first and last name. Also my company requires a password reset every few months so I have no idea what password might be being used. I've tried everything I could think of.

This didn’t make sense to me until I experienced it myself. When I booted into recovery to try to circumvent the login issue, the startup screen had my username displayed as my whole name all one word lowercase. (This was never my username in the past at any point.) I rebooted normally and this time put in the username I saw on the recovery screen with my usual password and I got in and Sonoma finished loading. What a joke! Apple screwed up huge on this one. So hard to imagine this slipped through quality control but here we are…

Update – this is no longer an issue for me. An update to MacOS Sonoma has fixed this with both the user and password fields always being presented.

I am currently on MacOS Sonoma 14.2.1 (23C71) on a Apple M2 Pro

We are seeing this issue as well. 5 Macs so far that do not recognize the login that worked previously. If we reboot a few times eventually it does work. This was after upgrading to Sonoma MAC OS

Downloaded Sonoma and my Mac won’t take my password. I’m going crazy-can’t get email or anything.

My account is locked and I cannot get an app. It shows up SS07. I’m trying to log into my account because my sister’s on there and I haven’t seen her in seven years.

I cannot access my emails since the Sonoma upgrade

how? when it comes to it's password what should I use?
