I have not changed the PC/SC layer provided by Apple.   I have merely build pcsc-lite in my home folder, in an effort to get ifdnfc to work.

The ifdnfc project page [1] claims that the "aim of this project is to bring PC/SC support for all readers supported by libnfc.".  Also, I got a tip [2] that  "By default, PC/SC Lite don?t know how to talk with cards, you need a driver for that.   For what I?ve see, a project is started called ifdnfc to bring this functionality and support NFC card for PKCS11 via OpenSC."

That sounds just like what I am trying to do.

Yes, that sounds like a good idea.

I think I need some help regarding to make that work.  nfc-list doesn't seem to cooperate, even when I use sudo:

$ sudo nfc-list
nfc-list uses libnfc 1.7.0
error	libnfc.driver.acr122_usb	Unable to claim USB interface (Permission denied)
nfc-list: ERROR: Unable to open NFC device: acr122_usb:020:005
nfc_initiator_init: Input / Output Error
