If automatic login is unavailable for an account
When manual login is required, the “Automatic login” menu is dimmed or doesn't show the account name:
- If FileVault is turned on, manual login is required for all accounts. You can turn FileVault off.
- If an account uses an iCloud password to log in, manual login is required for that account. You might also see the message “A user with an encrypted home folder can't log in automatically.” When changing the account password, you can choose not to use the iCloud password.
