Yubico Forum

I'm can't seem to get gpg2/scdaemon to recognize my yubikey 4. I've seen similar issues online but have not been successful myself.

I'm on Darwin:



On the surface, gpg2 does not work (installed via `brew`, but the dmg from gpgtools behaves the same).



This yields the common "can't select application `openpgp': Not supported" error message from scdaemon:



My configuration is pretty typical, though I've certainly tried various things:



The most common suggestion online is to set the reader-port, which I have done:



opensc sees the card fine:



pcsc test also reports positive looking things:



gpg1, which I'd prefer not to use, has different behavior:



I'll update this thread when I get around to trying on my Ubuntu system, but regardless of success there I'm going to need this working on the Mac.

ChrisHalos already had the answer here on the forum, the purpose of keeping a forum of old answers right? So thanks to yubikey and Chris.

The Ubuntu system did not work immediately but after running:



Things work all right. I say all right because

1. I still need to test the key on the Mac.

2. I can't figure out how to require the yubikey button to be pressed prior to performing a gpg signature/encryption. Any pointers?

After confirming 1 I'll mark this question answered and open a new topic on question 2.

EDIT:

As for issue 2, touch can be enabled as detailed on the getting started OpenPGP page (https://developers.yubico.com/PGP/Card_edit.html). Humorously, the shell script they refer to is A. not hosted on a yubikey account (though the user is part of the yubico organization as identified by github) and B. lacking any documentation such as what 'aut' means in the arguments.
