Mac Pinentry problem

[Rainer Hoerbe]

I copied my key to a OpenPGP card and was able to create signatures and authentication via SSH using the card. Now moving the the Mac I am stuck with pinentry-mac, because it keeps asking me for another card.

gpg --delete-secret-keys 0x64C2F99E904F1906
gpg2 --card-status
gpg2 --clearsign /etc/hosts

pinentry-mac brings up a dialogue box, asking to insert the card with the serial number D2760001240102000006030374100000. The Application ID (is this the serial number?) do not match.

What could be the problem?
