Mac OS Sonoma, MacbookPro 2018. Cannot save passwords, cannot set master password. Works fine on 3 other machines, cannot work on this one, I need this to work. I have tried everything including re-installation. I have deleted various old files per suggestions, nothing works. If I enter my email password with checking the checkbox to save it, everything works fine. If I check the "save in password manager" it fails and the email fails. a master password is not set and nothing I have tried will let me set one. It's making me crazy.
