I updated to macOS BigSur, but after entering my password login is stuck. I tried couple approaches:

  • starting in safe mode;

  • reseting PRAM/NVRAM;

  • reinstalling BigSur;

  • also tried removing Csstore files described here Macbook Pro stuck after I enter my password

  • I even did full disk erase and installed BigSur, then imported my data via migration assistant but still cannot log in to my account;

but it did not help. I have other accounts and I am able to login there. I also tried from those accounts to login with su my_username with terminal. I also changed the password that way, but all that did not help. I found the crash description in the logs of my user under ~/Library/Logs/DiagnosticReports/ and it seems that accountsd is crashing, bug type 309.

Is there a process to fix this error?

I had this exact situation but migrated from something old to Monterey, but what worked for me was this other solution: https://apple.stackexchange.com/a/412232/66547.

Specifically, say the migrated user was "Joe User":

  1. Login with the original admin account (or create a new admin account)

  2. Find the UID (user id) of the migrated user: id joeuser (say 502)

  3. Ensure the ownership of the migrated user's home folder: sudo chown -R 502 /Users/joeuser/

  4. Delete the migrated user with the Users & Groups control panel. Choose the option to keep the user folder as it is. It will get renamed from joeuser to joeuser (deleted)

  5. Go to the Users folder on your hard disk and re-rename joeuser (deleted) again to joeuser.

  6. Ensure the ownership of the migrated user's home folder again (it might not have let you do all of it while an account existed): sudo chown -R 502 /Users/joeuser/

  7. Add "Joe User" again with Users & Groups control panel. Make sure it gets the same user folder name (joeuser) and select the option to use the existing folder when you create it.

    • I did not set a password
  8. Turn on "fast user switching", and switched to the joeuser account

  9. It should show the account setup screens and asked you to connect to iCloud and set a new password

Bummer. Before you try and reset the password, have you tried a safe mode start? (Power down, hold shift as the Mac starts)

Here is the script to reset the password when it’s not working anymore.

    I tried all of that. What I am doing now is manually copying data to new user :S

  • How did you get past the stuck login screen @nedo99 (or do you still have admin access to the Mac and only one account is “borked”)

    I did not pass it. I had a 'admin' account and I could log in to that one, and in the end I made that one my account by copying data manually.

  • That’s a valid way to leave behind a broken user profile / keychain / preferences. Great solution @nedo99

    And those settings are highly sus now as to the cause of the issue @nedo99 (since it’s not the OS, the hardware, the apps or the data)
