After installing GPG Suite on Mojave, i unable to open Mail. Or more correctly Mail starts, but main window does not open.

If i set EnableBundles to NO, i can again open Mail
`` sudo defaults write /Library/Preferences/ EnableBundles -bool NO

`` But if i set EnableBundles to YES, the problem persists.

I have tried to uniinstall and reinstall GPG Suite, to no avail.

I see that someone had same problem yesterday in this forum. The thread says resolved, but the solution is not posted.

Maybe someone could post the solution to this problem.

    Hi Mac2,

    unfortunately this happens due to a bug in macOS Mail on Mojave. We have filed the bug with Apple but it is unclear how long it will take them to resolve the issue.

    Following are the steps that should fix this problem:

    • Close
    • Open Terminal and run the following command:

    sudo rm -rf ~/Library/Containers/

    (If you receive a permission denied error, you might have to disable SIP. Please let us know if you had to do that.

    • Open

    If opens just as before, you can now re-enable plugins:

    sudo defaults write /Library/Preferences/ EnableBundles -bool NO

    Please let us know if that worked.

    Just wanted to let others know, who suffer from this problem, that this did the trick for me:

    Follow Luke Le's commands to delete DataVaults and afterwards setting plug-ins (bundles) to -bool YES (not NO).

    Then, I had to restart, went to preferences and selected "Manage Plug-Ins" in the General Tab. Then, check GPGMail, restart Mail App and the additional GPG tab is there!

    I am on Version 12.0 (3445.100.39), which is some nightly build referenced in a different " does not start" ticket.
