Update your system. (10.6.5 is the latest for Snow Leopard) Step 2: Plug in your CAC Reader to an available USB Port. Step 3: Click the Apple Icon in the upper left corner of your desktop and select 'About This Mac'. Step 2: Plug in and Ensure It’s Accepted. Once you have your CAC reader, plug it into your Mac and ensure your computer recognizes it. If you have one of the CAC readers we suggested above, then you should be good to go. Up until the release of Mac OS X Lion (10.7) in July 2011, Apple included native support for login using smart cards. Users have found it more challenging to make smart cards work with Mac OS X. The release of macOS Sierra 10.12 marks a new beginning for smart card users, as Apple has taken a step towards support for PIV compatible smart.
Hate to sound like a broken record, but since upgrading to High Sierra I have not been able to use my smart card reader. I am trying to access www. my.af .mil (Air Force Portal) to no avail; I get an 'Access denied' page. I have contacted the support department for AF Portal and they were confused as to why I was unable to log in. I had been able to log in with previous Mac OS, but not with High Sierra.
