"There is no application set to open the URL x-onepassword4://quit. " error message every time

@cooksfarmer22

Can you tell me more about the URL you are using? Off-hand it sounds like you may have a URL saved from a previous version of 1Password. One-click bookmark? If so, those will not work with 1Password 8. I would suggest looking at Quick Access

If you have something setup you might try removing the "4" from the URL. Without context I cannot say if this would benefit you.
