1Password has detected an error (macOS Tahoe)

Hi there,

I recently migrated information from an external SSD to a new macOS Tahoe installation, and this prompt occurs upon each login.

Could I have some support with this? Should I simply just download and reinstall 1Password again such that this error goes away? Thank you!

I'm sorry that those steps didn't work with your situation, please try these alternative steps: 

🚨 Before proceeding, make sure that you have a copy of your Emergency Kit, that you know your account password, and that you're signed into 1Password on another device and see all of your items there.

  1. Close all browsers.
  2. Right-click the 1Password icon in the menu bar (if it's there) and click Quit.
  3. Open Finder, and click the Go menu > Go to Folder...
  4. In the box that appears, copy and paste the following exactly: ~/Library/Group Containers/
    • and press ⮐ Return.
  5. You'll see a folder called 2BUA8C4S2C.com.1password. Rename it to 2BUA8C4S2C.com.1password.old
  6. Wait a few moments and then open 1Password. You'll be taken through the first setup process. Add your 1Password account back to the 1Password app.
  7. Follow the prompts to setup 1Password and configure any settings that you had configured before. 


Let me know if you run into any issues.

Hello @ThePaleKing! 👋

I'm sorry that you're seeing an error message when attempting to launch 1Password on your Mac. This issue can indeed occur when moving 1Password's local cached database from one Mac to another, you can resolve it by resetting the app: 

🚨 Before proceeding, make sure that you have a copy of your Emergency Kit, that you know your account password, and that you're signed into 1Password on another device and see all of your items there.

    Hi Dave,

    I cannot complete step 1, as I do not have a `settings` option underneath 1Password on the menubar.
