Hello, I went on this mail about the way secdebug is working : https://lists.macosforge.org/pipermail/smartcardservices-dev/2010-January/00... I tried to send a mail to the developer technical support, but the way support is working has changed. I posted my question on the developer forum but since smartcard services and tokend are deprecated, I don't know if I will get an answer. So I post it there too : I would like to know where the debug messages are sent and how to activate them ? (not so far from the question asked by Ludovic Rousseau in the previous link) Regards, Dominique # " This e-mail and any attached documents may contain confidential or proprietary information.
