Hello,
On macOS Sierra 10.12 GM, pcsctest well recognized a Smart Card reader.
But when I run a PCSC sample provided by Ludovic Rousseau,
I have the error "Transaction Failed” (SCARD_E_NOT_TRANSACTED) on first “SCardTransmit”.
"SCardEstablishContext", "SCardListReaders" and "SCardConnect" succeed.
This sample runs successfully on macOS Yosemite 10.10 and macOS El Capitan 10.11.
Do you have an idea about this issue ?
Has PCSC framework changed in macOS Sierra ?
Thanks.
Frédéric
