I have 1Password 6, running on my two Macs. "About 1Password says my registration (good for 5 users, on an unlimited number of Macs) dates from 2013.
Apple has just released Safari 13, which won't permit installation of the 1Password Extension from version 6. I'm relatively certain that if/when I update to Catalina, I won't be able to prevent the simultaneous installation of Safari 13. I don't know what kind of license I have, what my options for updating are, and what I'll need to do to preserve my vaults (as well as what I'll need to do as regards my iOS devices.
My synchronization occurs in Dropbox. Apparently I'll need to upgrade to 1Password 7, but I don't know what "flavor" of 1Password 7 we'll need, both in macOS and in iOS/iPadOS
I have a Gen 5 Apple watch (which of course will require WatchOS 6 on order. I plan to upgrade to an iPhone 11 (probably an 11 Pro) which will mean updating iOS to iO3 13. My 2016 4-TB3 port MacBook Pro 15," my wife's 2017 non-touch bar 13" MacBook Pro, and my late 2017 21" iMac (quad core i7) are all running Mojave 10.14.6. For now, I think we'll hold off on updating them to Catalina.
Can you help us with this matrix?
