Body
If you encounter an issue where a user changed their password recently and they cannot login to their Mac then do the following actions:
- Log in with administrator account
- Open the Terminal application (click the magnifying glass in the top right and type in terminal).
- Remove the account first from Filevault using this command:
- sudo fdesetup remove -user <USERNAME>
- Type in the administrator password
- Log out and log back in as admin. You might be able to skip down to the deprecated commands below, without logging out.
- Open System Preferences > Privacy & Security > scroll down to "Filevault"
- Click Enable Users... > put in the Administrator password > Have the user put in their password > Click ok.
Restart and have the user try to log in again - TWICE, to make sure they can log in on their own.
DEPRECATED DIRECTIONS:
- Re-add the account using this command:
- sudo fdesetup add -usertoadd <USERNAME>
- Hit enter, and type the following for the prompts:
- Enter the user name: administrator
- Enter the password for user 'administrator': <ADMINISTRATOR PASSWORD>
- Enter the password for the added user <User PASSWORD>
- Restart the computer and have the user try to login again.
