1Password 3 and 4 beta and 4 on OSX 10.8.4.
I tried one of the 1Password 4 betas, but never used it as my "primary" program. That is, I imported data from 3 initially, and played with 4, but used 3 as my primary program.
When I upgraded to 4, it did not ask about importing data from 3. That makes me believe that it is using the data from 4 (which is old), not the data from 3. But, I have no way to prove that, since I can no longer get into 3.
So, I have 4 (called 1Password) and 4beta (called 1Password 4), and they appear to have the same data, but neither of them is the most current data that was in 3 prior to the upgrade.
So, where to from here?
