1Passoword 8 on macOS Mojave

@anjanesh there is indeed a minimum requirement of MacOS 10.15 or later to install 1Password 8. Some features of 1Password 8 were coded specifically for newer versions of MacOS and will not work with older versions of the operating system, which is why that minimum requirement is there. If you can update your operating system, we strongly recommend that you go for it, since working on such an outdated operating system is quite a security risk, regardless of 1Password.

However, in case you are unable to upgrade your operating system to use 1Password 8, you can continue using the 1Password extension in your browser. While we can't guarantee that the extension will work on an older system, it does not depend as much on the version of macOS you are running.

As a note, you had mentioned a warning about the extension in your first message https://1password.community/discussion/140879/1passoword-8-on-macos-mojave. The screenshot that you shared is in regards to the app and does not mention the extension. Are you getting a separate warning or error message about the extension? If so, please share a screenshot of that and we'll take a closer look at it.

Hey @anjanesh, sorry about the delay in responding. I understand that you are unable to upgrade to 1Password 8. I can check on the warning that you're seeing for the extension. What browser does that occur in? Could you share a screenshot of the warning that you're seeing?

Don't forget to attach the screenshot to your reply. We hope to hear from you again soon
