About the error
If you see this message from the App Store, you won’t be able to update 1Password until you completely quit the app.
What you should do
To update 1Password, dismiss the message and completely quit the app:
- Click Cancel to dismiss the message.
- Quit 1Password completely:
- Open 1Password and click the 1Password menu.
- Hold down the Control and Option keys on your keyboard. While holding the Control and Option keys, select “Quit 1Password Completely”.
- Open the App Store and check for updates.
If you want to get future updates directly from 1Password instead of the App Store, switch to the version of 1Password from the 1Password website.
