Problems with Apple Mail - GPG doesn´t work

I have a MacBook with GPG Tools and installed Sec/pub Keys (latest Mojave and latest GPGSuite 2018.5) - it works!

I have also an iMac Mid 2011 with HighSierra and also GPG Suite 2018.5 (with all my sec/pub certificates, too!).
Until now I use Apple Mail with a S/MIME certificate.
But Apple Mail doesn't work with GPG Tools.
In Apple Mail I haven't a green button and no availability to click the encrypt button.
I'm also wondering about the entries in the attached file: Why is the line with GPG Mail blank?

Thanks for your help, best regards,

What did you expect instead

Describe steps leading to the problem.

Are you using any other plugins?

    Hi Thilo,

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

    Can you re-download GPG Suite from our website and re-install.

    Does that bring back GPG Mail?

    Hi Steve,

    Thank you! I have re-installed the GPG Suite and now it works.

    Do you have an idea for using openPGP/GPG for iPhone iOS?

    Best Regards

    Thanks for your interest in GPGTools on the iOS platform. We are still evaluating options concerning a solution. In near term that is out of scope for us, since Apples does not allow plugins in Mail on iOS. So in short we would have to develop our own mail client. On the iOS App Store the following OpenPGP solutions are available:
    Canary Mail iPGMail

    For Android there is
    OpenKeychain with K-9 Mail

    In any case, please make sure to not transfer any secret keys via email. Use iTunes file transfer for that.
