I have installed the latest GPG Suite 2019.2 and I still get this error at Mail launch on latest macOS 13.15.5, Mail app version 13.4.

What can I do?

Thank you

    Hi Andrei,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    What you describe is unrelated to any issues with your support plan, but rather a bug in macOS Mojave/Catalina which sometimes prevents plugins from loading due to faulty permissions.

    In order to fix that, please follow these steps:

    The solution is to enable Full Disk Access and after that running a Terminal command.


    1. Close
    2. Open System Preferences › Security › Privacy
    3. Enable Terminal under Full Disk Access
    4. Restart Terminal when prompted
    5. Run the following command:

      rm -rf ~/Library/Containers/

    6. Open Mail

    If that doesn’t help, you will have to disable SIP and run step 5 again.

    Please let us know if that brings you back to working state.

    All the best,
