This has happened repeatedly, am trying again to solve it. Uninstalled the app this morning, emptied the trash, reinstalled by downloading the installer from the 1Password site after logging in. The app appears, but when double-clicked it does not come up fully--this time the menu bar showed the icon but the spinning beachball was present if I hovered. Force Quit Applications showed the app as nonresponsive so I force-quit.
Restarted the Mac, then again tried to double-click the application with the same results (the mini also did not show up after the restart).
1Password 7 works fine on my personal iMac, 2 phones, and an iPad. The work laptop differences, possibly relevant, are that my user account does not have admin rights to install applications, so I have to authorize an admin account to complete the installation (and uninstallation).
On some previous attempts, I would occasionally be able to bring up the application but the mini would hang, or the Chrome extension would show but fail to operate, etc. Today no method seems to get 1Password working on this computer.
Side note: the automatic attempts to send a user to the application to get support, or information for a support question, aren't very good if the application isn't working at all.
