Username change

hello,

I changed my username from the preferences->users and groups->rightclick on the account -> advanced options and then changed the full name (and did not check the warning). As a result, i cant unlock the locker even though i write the right username and password. And to mention i have not a second account on my MacBook or a Guest User. Does anyone knows how to solve this problem?

Thank you!

Restore from a backup is the simplest way...



Change the name of your macOS user account and home folder
