How To Install Cac Reader For Mac

Step 1: Purchase a Mac Friendly CAC Reader

Purchase a CAC reader that works for your Mac. There are only a couple that you can choose from and I’ve listed them below.

If you already have a CAC reader and it isn’t Mac friendly, you could update the firmware, however, for the non-tech savvy people out there, it’s probably better to just purchase a new one and save the headache – they’re only ~$11-13 dollars.

Step 2: Plug in and Ensure It’s Accepted

Once you have your CAC reader, plug it into your Mac and ensure your computer recognizes it. If you have one of the CAC readers we suggested above, then you should be good to go.

If you are testing a different version, then verify that your Mac accepts your CAC reader by following these steps.

If for some reason your CAC reader isn’t working, then try the following steps.

Step 3: Update Your DOD Certificates

Now that you have your CAC reader connected and accepted on your Mac computer, it’s time to ensure you have the right certificates in order to access DOD CAC required web pages.

Common Reasons Why Your CAC Card Won’t Work On Your Mac

Ensure Your CAC Card Meets the Standards: In order for your CAC card to work, it must meet the minimal requirements. Currently, there are only four types of CAC cards that can be used. The ensure you have the right CAC card for online access, flip your CAC card to the back and if you have one of the below numbers written on the top left, then you are good to go:

• G&D FIPS 201 SCE 3.2
