Sorry to hear you’re having troubles with 1Password. It sounds like you might have been working with a previous 1Password version (1Password 6 or earlier) with a standalone license, and then updated to 1Password 7 when you updated your Mac.
1Password 7 requires a 1Password.com account, which you can sign up for here: https://1password.com/sign-up
Once you create an account and add it to the 1Password 7 app, it will be activated and autofilling should work.
If that is not the case or if you are still having troubles, please do contact us at support@1password.com and we’ll be more than happy to help!
