Smart Card support for Safari on a Mac running OS X (10.7.5)

Adding Smart Card support to Safari on a Mac running OS X 10.7.5 works well using an application called Open Smart Card or OpenSC. It's homepage says it works with OS X versions between 10.6.x to 10.8.x, but does not cover Mavericks.  This tutorial will focus on using Safari to authenticate to the AF Portal at https://www.my.af.mil. This method also works for reading unencrypted email with Outlook Web Access. So this should cover Snow Leopard through Mountain Lion, at least.
          • Connect a Smart Card reader to the mac.
            • If a reader still needs to be purchased, more information is available in the PKI Tutorials section of Security Endeavors.com under Use a Cert > Home Use > Get A Reader
            • Allow a few moments for drivers to be loaded when newly connecting any reader
          • Install the DoD Root Chains to trust and use the CAC/PIV certificates 
            • Close Safari 
            • Open Applications, then open the Utilities folder and double-click Keychain Access
            • Select File > Add Keychain
            • Click the Keychains drop down and select the hard drive icon to go to the top level of the disk
            • Navigate to System > Library > Keychains
            • Select SystemCACertificate.keychain, then click Add
            • Enter your Keychain password if asked to do so (same as login in most cases)
            • Close the Keychain window

          • Download and install OpenSC (Open Smart Card), the software that lets applications like Safari talk to the certificates on a CAC/PIV token
