Updating 1Password macOS client broke Safari extension I recently started using 1Password on my MacBook Pro running macOS High Sierra 10.13.6 with Safari Version 11.1.2 (13605.3.8).

I have both the macOS app from the Mac App Store and the Safari extension for the app installed from 1Password - Safari Extension Gallery.

I have been looking forward to give 1Password a try for a very long while (which I finally did). I am quite satisfied with the feature set and simplicity of the product.

However, I updated to the latest macOS client released on the Mac App Store today, which broke the Safari Extension for me. The screenshot below shows the release notes.



Now, when clicking on the Safari extension button on the toolbar, with a website open (which is already added in the 1Password database), does the following instead of offering to fill the password:


Nothing happens for a few seconds.
Following alert is shown by Safari.





Irrespective of whether I click Allow or ignore the alert and wait, this error is shown.




The 1Password macOS app doesn't launch. Even clicking on Try Again does nothing.

The thing is, that, this setup was working flawlessly until I updated the macOS client.

What could have possibly gone wrong? I have not attempted any major salvage operations, as this is the first time I have setup 1Password app on my Mac.

I am thinking about doing a fresh install of the app and checking if the issue persists (thereby concluding that this is a bug in the app release).

I have already clicked on the support site link mentioned with the error message, and have reinstalled the extension, following by restarting the browser followed by restarting the Mac, but to no avail.



I have not taken any other steps on my own and though of seeking advice from experienced 1Password users. (I have been using the app for a couple days. I am currently under 1-month free trial with a high level of satisfaction and intend to convert to paid plan at the end of trial period expiry.)

Salvage Update: It is observed that that the mini app which is resident in the Menu Bar is no longer recognizing the browser extension and asking to install it. Clicking on the install browser extension button directs to the Agilebits Safari Extension Galley web-page which acknowledges the extension installation. Removing and re-installing the extension has no effect.
I've seen this one. It just means that the 1Password background app is either hung or quit somehow.

Usually a reboot does the trick, if not after a reboot launch the 1Password app, and see if that does it.

Still not working? Uninstall the extension and reinstall it. that should do it
