bradl, I don't mean to sound argumentative. I appreciate your many thoughtful posts in this thread! I don't get it though -- why do you speak as if 1Password is nothing more than the /Applications/1Password.app bundle? In my eyes it's the browser extension that determines whether or not '1Password' is a viable option for any given operating environment. Even though 1Password v6 works on High Sierra, for instance, it doesn't work on the latest version of Safari that works in High Sierra. This 'browser extension' aspect works in AgileBits's favor -- the company has every incentive to *not* update browser extensions for old versions of 1Password.app.Exactly.. they are still supported, with exception to the architecture issue that is going to come up when Rosetta 2 is dropped from MacOS. At that point, 1PW 6 will still continue to be supported for those operating systems it can run on, but will not be able to run on anything non-Intel. 1PW 7 will.
BL.
So, in summary, even though 1PW 6 'will still continue to be supported for those operating systems it can run on', the app loses much of its usefulness once the user updates Safari (true perhaps for other Web browsers, too?).
