I have been using 1Password 3, 4 and then 5 on Windows, Mac and iOS (family sharing).
I think this is a legacy plan/versions and for few reasons I am not planning to move to latest versions.
Saying that can you help me figure out the latest legacy versions for:
1) Windows 10 (I think it is 4.6.2)
2) Mac latest OS (is it 5 or 6.8.9?)
For some reason on Mac I have version 5 and during update it installs version 6, and somehow my sync between iOS/Mac is screwed up.
I have using dropbox to sync between devices.
