MacBook Air asking for CAC pin even when I don't have the CAC reader connected/CAC inserted Subject line sums it up well. I sometimes use a CAC reader with CAC on my MacBook Air (M1, 2020) to access my secure work website (military). But sometimes, even when my CAC reader isn't connected, and when I open up my Mac to login, it asks for my PIN (associated with my CAC reader/CAC card), and won't let me log on unless I plug in my CAC reader, insert my CAC card, and put in the pin. This is a pain for obvious reasons. Anyone else encounter this problem? Any fixes? I have no problem with the Mac asking for my pin when my CAC reader and CAC are actively connected, but it makes no sense for it to require my pin when I'm not even using the CAC reader. Thanks!

Hi there, JGW111!

Thanks for reaching out to the Apple Support Communities! That's an excellent question you have about installing and using a CAC reader on your MacBook Air. Please check out this article to Configure macOS for smart card-only authentication. You'll also need to reach out to the manufacturer of the reader for additional steps you'll need to take to install and use the reader.

Thanks again for the question and take care!
