Step 1: Update 1Password from the Mac App Store
Open the App Store app, then click Updates. If updates are available, install them. If no updates are available, go to the next step.
Step 2: 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”.
In 1Password 6 and earlier, select "Quit 1Password and 1Password mini" instead.
Step 3: Download 1Password from the 1Password website
Download 1Password from the 1Password website and install it. Open 1Password, and you’ll see the Welcome screen. After answering the configuration questions, you’ll see all your Logins, Secure Notes, and other data.
The version of 1Password from our website requires its own license or 1Password membership.
All of your preferences will be reset, so if you were previously using an advanced sync option, reconfigure your sync settings.
Step 4: Check for older versions of 1Password
In Finder, open the Applications folder. If you see “1Password” or “1Password 6”, move it to the Trash. Keep only “1Password 7”.
Be wary of using an uninstaller app like AppCleaner, AppZapper, CleanApp, and other similar apps. Uninstaller apps prompt you to delete supporting files when moving an app to the Trash, and this can result in accidentally deleting all of your 1Password data.
