DO NOT DISABLE on 10.15.x, there is NO alternative

NOTE: Mojave, High Sierra, and Sierra have a 'built in Smart Card ability' that works for 'some' people 'some' of the time. To use your CAC 'more consistently' I recommend you install a 3rd party CAC enabler, such as CACKey or PKard. This section shows you how to disable the built in smart card ability found on Mojave, High Sierra, and Sierra.

NOTE2: Doing this will remove the ability to login to your computer with your CAC, and will require you to install a 3rd party CAC enabler such as CACKey or PKard.

1. Remove your CAC from the reader

2. Open Terminal, by typing Terminal in the spotlight search

3. Copy the command below [starting with sudo, and ending with pivtoken] and paste it into the terminal window (or manually retype it)

sudo defaults write /Library/Preferences/com.apple.security.smartcard DisabledTokens -array com.apple.CryptoTokenKit.pivtoken

3a. I recommend you run this command twice.

4. When prompted for your computer password, know that the cursor will not move, type it in, and hit enter to process.

5. After that it should be disabled. Logout of Terminal, restart computer, and try again

NOTE3: If you have recently updated to Mac OS Catalina (10.15.x) or Mac OS Big Sur (11.00.x), you need to re-enable the built in Smart Card ability after removing all installed enablers listed above:

1. Remove your CAC from the reader

2. Open Terminal, by typing Terminal in the spotlight search

3. Copy the entire command below [starting with sudo, and ending with pivtoken] and paste it into the terminal window (or manually retype it)

sudo defaults write /Library/Preferences/com.apple.security.smartcard DisabledTokens -array && sudo defaults write /Library/Preferences/com.apple.security.smartcard EnabledTokens -array com.apple.CryptoTokenKit.pivtoken

3a. I recommend you run this command twice.

4. When prompted for your computer password, know that the cursor will not move, type it in, and hit enter to process.

5. After performing these steps, the built in smart card ability should be enabled.

6. Logout of Terminal,

7. Restart computer

8. When prompted to Pair your Smart Card with your computer, you can select Pair, or Cancel. If you elect to pair, you will have an additional option to utilize your CAC and PIN to access your computer [when the CAC is in the reader]. If the CAC is not in the reader, you can still use your fingerprint, or username/password option.
