When I write a new mail and select OpenPGP on the top right corner everything works but when I select S/MIME the button is grey instead of green and it doesn't encrypt the message, though it alerts me it doesn't. I created pub/private keys and uploaded my public to the keyserver pool, I tried all the option to no avail. The OpenPGP option as well as the inline PGP both work amazingly though so great job !

I'm using the latest stable version of GPGtools on macOs Mojave with everything up to date and installed from the .dmg

    Okay sorry I misunderstood the inner workings of S/MIME. Turns out you need to install a certificate signed from a CA in order to use it. After getting a free S/MIME cert signed by a big CA I could sign my messages in S/MIME and encrypt them.

    So no issue with GPGTools, sorry for disturbing you.

    Hi Samuel,

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

    To add some more information - this security stackexchange thread covers the questions how OpenPGP and S/MIME differ:

    All the best,
