After upgrading to macOS 27 I’m finding the Safari extension really slow and un responsive. In the extension settings in Safari I see the following errors reported against the extension?

Hello @David73! 👋

I’m sorry that 1Password for Safari isn’t working correctly in your browser. Can you try the following steps to see if they get 1Password for Safari back into a healthy state:

Go to Safari > Settings > Extensions.
Disable 1Password.
Force close Safari: How to force an app to quit on Mac
Open Safari again and enable 1Password for Safari.

If you still see the same issue then can you tell me if you have Lockdown Mode enabled on your Mac? And does the issue still occur if you disable your other extension?

Hi, thanks for the reply Dave. I’m not running in lockdown mode. I followed the steps, and while it has reduced the number of errors listed against the extension, they are still there, but the extension does feel a bit more responsive.

Thanks for the reply. Do you see the same messages on any other extensions in the extensions settings page?

Is everything back to normal or are you still seeing some performance issues?
