Parallel Use of GnuPG and MacGPG

I recognized that GnuPG currently has a much newer version of gpg ( 2.2.17 vs 2.2.10 ) and libcrypt. So I installed GnuPG in addition to the MacGPG Suite. Now I have the problem, that a gpg2 --card-status brings a lot of warnings (about the older MacGPG tools) and is not running the first time.

The warnings also show a solution (gpgconf --kill all ), but it would be great to get it up and running the first time. So is there a How-To to understand how-to setup both on the same Mac ? ( Just to feed the newer tools into MacGPG ) ?

    Hi Peace Keeper,

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

    I would not advise that setup.

    You can download and install our latest hotfix GPG Suite. It includes MacGPG 2.2.17 and an updated libgcrypt.

    All the best,

    Disclaimer: This is a development version which has not been thoroughly tested yet - bugs or crashes are to be expected. Thanks for helping us test.

    I have now de-instelled the GnuPG Package and only the MacPG is active ( beside an scd-pkcs11 lib )

    So is the Hotfix used without the GnuPG package ?

    could you please elaborate what you mean by "Hotfix used without the GnuPG package ?".
    To add more information to your first question, it is not really possible to run two different versions of GnuPG side-by-side and one reason for that is, that gpg-agent – the process which handles the passphrase caching, unlocking of the secret key for decrypting and signing message – is launched on demand, as are other processes. However, if one is already running, which was the case in your case, GnuPG will complain that the versions don't match.

    Our latest hotfix contains the latest GnuPG version soon after its release by, so what you can do is to install only MacGPG/GnuPG from the latest hotfix by following this guide:

    Hope that helps.

    Hi Luke,

    ok, you explained it, why it is not working to have both (MacGPG and GnuPG) versions installed. So I now have only installed MacGPG and scd-pkcs11lib and it works so far. I will open a different topic for a different question.
