The CAC reader light blinks when I insert the card, then stops, learned about the various types of smart cards and how they interact with various operating systems. 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). I am hoping someone knows of a plist file or command I can run that will make my certs show in the select certificate window for 3rd party apps :) I have not reloaded the laptop from scratch and will eventually but have to move a lot of files off first.ĭoes this behavior have anything to do with not having a T2 security chip? I have gone through the remove steps several times. I do not have any CAC enablers installed, but did prior to Big Sur. CAC info does show in command line tools such as scauth, etc. I also assume that the window is populated from Keychain accessĬAC does not show in Keychain Access and I guess PIV certs don't (maybe that should be fixed). I have no other apps that use certificates so I assume that it is not working for all apps that request the user to select an app. According to Pulse Secure's website it should work with Big Sur. when I use either Pulse Secure or MS Teams and I get to the point where the window pops up and asks the user to select the cert, it is blank. From this perspective it seems the CAC is working just fine.īut.

It works to unlock the screen, for sudo in terminal, I can get to all needed websites in both safari and chrome.

I have paired my CAC with my mac's user account. My scenario after doing the many things I found to try to get PIV certs working is that they work for most things but not for 3rd party apps that pop up a window to choose a cert. My PIV cert is a military CAC and I have done all the steps at I have googled many times and read posts similar to this question but I haven't found the solution or perhaps a reason why PIV certificates work the way they do.
