I recently upgraded from Yosemite v10.10 to El Capitan v10.11. As soon as the upgrade was complete, I downloaded the new v2.1.2 installer, ran it successfully, but after I attempt to get onto my.af.mil <http://my.af.mil/>, I get the "CAC error" screen. This doesn't happen on my other computers and I have swapped out the card readers, which all work on other computers. Is there any fix to El Capitan?
