I have a new MacBook Pro with the new USB Type-C ports and using a simple adapter prevented me from accessing CAC enabled websites. I went to my trusty old website: MilitaryCac.com and it listed this CAC reader as the one that will work with the new USB ports. I connected it to my MacBook and it worked straight away! I know I can access my OWA email and other military websites, so I can work from home if needed without using my much larger iMac desktop.
