Hope this helps others who upgraded to Monterey because this really shut me down for a bit and even wasting money another CAC. (RESOLVED) I had to go to the Terminal and do the commands it states in this link: - I recall seeing this but it recommends I do it twice….after that and a restart, the certificates popped up. The CAC reader light blinks when I insert the card, then stops, and.sigh. I verified all required DoD certificates are installed and trusted, but I get nothing. My CAC is no longer paired and I cannot log into any DoD PKI-enabled website.

Which worked under 10.15.5 and 10.15.6, but now appears not to work. 'sudo defaults write /Library/Preferences/ DisabledTokens -array & sudo defaults write /Library/Preferences/ EnabledTokens -array ' I've reloaded all certificates, checked to see if the CAC reader itself is still recognized (it is - model SCR-3310), but nothing. Today, we were told to stay home because someone near our office space tested positive for COVID-19, so I stuck my CAC card in the CAC reader and.nothing.

In those two weeks, MacOS updated from 10.15.6 to 10.15.7. I started back in the office, and hadn't needed to telework for a couple of weeks. MacOS 10.15.7 no longer pairs CAC PIV? I was able to use my CAC/PIV on MacOS 10.15.6 through the entire 'telework due to COVID-19' period (for me, that was from mid-March through a couple of weeks ago).
