Is it safe to use 1Password nowadays on macOS Mojave?

Hello @herodes! 👋

Thank you for the question! The honest answer is that I can only recommend running the latest versions of both MacOS and 1Password. Older versions of any software don't receive the latest security updates and as a security company 1Password always recommends being up to date with the latest patches and updates available.

macOS Mojave is no longer supported by Apple. It looks like MacOS Mojave's most recent version is 10.14.6 and it last received an update in 2021. That means that two years of bug fixes and security mitigations are missing from your Mac which can put you at risk.

The same is true for 1Password for Mac. I recommend running the latest version at all times since this is the version that has the latest security updates and bug fixes. I hope that helps.
