Upgrading from 1Password 3.? to 1Password 7 subscription

Hi I recently upgraded my MacBook to Mojave and my old version of 1Password (3.something) which worked perfectly for me has stopped working.

I upgraded to the V7 subscription but cannot import my old data. Have tried everything. This has left me rather screwed.

Any help gratefully received.



1Password Version: 3.1 Old to V 7
Extension Version: Not Provided
OS Version: 10.14
Sync Type: Not Provided

    Welcome to the forum, @paba873! I'm sorry for the trouble. 1Password 3 for Mac was a great product in its day, but (believe it or not) it was introduced almost exactly nine years ago, in November of 2009. The last meaningful update was in mid-2012. We're four full versions past it now, and (as you discovered), time and changes in both macOS and other technologies (browsers, etc) have rendered version 3 essentially unusable in macOS 10.14 (“Mojave”).

    However, we've got a great, step-by-step guide for upgrading from version 3. Give that a try, and let us know how you get on. Make sure you remove old 1Password extensions from your browser(s) when you're done.
