Operation not supported by device

[Stefan Claas]

Hi all,

when clear signing a text file, with the latest version of GnuPG under
macOS, i get the following message:

gpg --clearsign loremipsum.txt
gpg: selecting openpgp failed: Operation not supported by device

The file is signed and can be verified. Just wondering (after googling)
what this means, because i have no card reader etc. for GnuPG.

Regards
Stefan
