Question: how do I install my Primo Smartcard reader on Mac?

The card reader does not use external drivers for installation but the standard Mac drivers (appears as EMV Smartcard Reader in the device tree). I recommend disconnecting the card reader from the computer. Restart your computer and reconnect the card reader when Mac is fully loaded. 

To use the card reader, you must install the software of the government agency in question for which the digital signature will be used. This software is not provided by Trust, but varies by government agency.
