Administrator name/password is not working while trying to allow
Hello ! I'm trying to allow the usage of a personal keychain for verification of a document and when I introduce the User Name and Password I use to log into my macbook (its the only account on this machine and I confirmed I am the administrator in Users and Groups) it does not allow me to do it, as in my password or username is incorrect. I need help with this.
MacBook Pro 16″, macOS 14.4
