I am in the military and use my CAC to log into military sites and digitally sign documents. I read somewhere that all the architecture for a CAC reader is already embedded on a Mac but I can't seem to make it work. I love my Mac and would really like to be able to do EVERYTHING on it instead of having to revert to Windows for certain things. I have seen Macs being used in the workplace in the Army while using a CAC reader and card, but no one has been able to tell me how it was done. If anyone has any advice or can point me in the right direction, I would really appreciate it.
