Troubleshooting Military CAC Card Issues with macOS Monterey

Are you experiencing issues with your military Common Access Card (CAC) not pairing with your Mac running macOS Monterey? You're not alone. After upgrading to the latest operating system, many users have reported similar problems. In this article, we'll guide you through the steps to resolve the issue and get your CAC card working again.

Step 1: Re-enable Built-in Smart Card Ability

If you've recently updated to macOS Monterey (12.00.x), you may need to re-enable the built-in Smart Card ability after removing all installed enablers. This simple step can help resolve the issue.

Step 2: Check and Reloading Certificates

Verify that all required DoD certificates are installed and trusted on your Mac. If not, reload them by following the link provided in this article. Additionally, check to see if the CAC reader itself is still recognized (in my case, I have a SCR-3310 model).

Step 3: Use Terminal Commands

If the above steps don't work, you may need to use some terminal commands to resolve the issue. Copy and paste the following command into your terminal window:

`sudo defaults write /Library/Preferences/DisabledTokens -array`

and then

`sudo defaults write /Library/Preferences/EnabledTokens -array`

If you've followed these steps and still encounter issues with your CAC card not pairing with your Mac, there may be a more complex problem at play. However, by re-enabling the built-in Smart Card ability, checking and reloading certificates, and using terminal commands, you should be able to resolve most common issues.

Remember to stay safe during these uncertain times, and we hope this article has helped others who have upgraded to macOS Monterey and are experiencing similar CAC card pairing issues.
