In the right hand side you will see the certificates that are on your CAC. If in the upper left of the Keychain Access window, under 'Keychains' your CAC should show up (CAC XXXX-XXXX-XXXX-XXXX-XXXX), select it. Step 9: Insert Your CAC Card into the Card Reader. I could see the certificates on the CAC but sites like the AF and JFCOM portals wouldn't let me get on! BTW, it worked under 10.5.6 and everything worked Golden under 10.6 (Snow Leopard). I got some additional info from that helped put the final touches in place. I've got everything (with the exception of the pig known as DTS) using an SCR3310 reader and a recently issued Oberthur card.
