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.

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 for some reason your CAC reader isn’t working, you may need to download the appropriate drivers for your CAC reader. You can find these drivers on the Reader’s Manufacturer Website.

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.

4. Download the following five files and double click each once downloaded so as to install in your Keychain Access.
5. When you double-click the Mac Root Cert 3 and 4, you’ll need to tell your browser to always trust them. Click the button like you see below:

Additional Steps for Firefox

If you’re using Mozilla Firefox as your primary browser, you’re going to need to perform some additional steps. First, perform the same steps that you did for Chrome and Safari. Afterwards, follow these additional steps to get started.

1. Download All Certs zip and double click to unzip all 39 files
2. While in Firefox, click “Firefox” on the top left, then “Preferences”
3. Then Click “Advanced” > “Certificates” > “View Certificates”
4. Then Click “Authorities” and then “Import”
5. Import each file individually from the “AllCerts” folder. When you do this, the below box will popup. Check all three boxes and click “OK”

Step 4: Download and install CAC Enabler

Choosing the right CAC enabler can be pretty tricky. It all depends on what OS you have installed, how you installed it, and even what kind of CAC Card you have!

In order to get the right enabler, be sure to visit our trusty guide to Mac CAC Enablers! It’ll walk you through exactly which enabler is right for you.

CAC Access at Home Success

Now that you have a CAC reader, certificates, and a CAC Enabler, you should now be able to access any CAC-enabled website and log on using your CAC password and data.

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
• Oberthur ID one 128 v5.5 Dual
• GEMALTO DLGX4-A 144
• GEMALTO TOP DL GX4 144

If you do not have any of the above written on the back, then proceed to your nearest PSD to get a new CAC card issued.

The Refresh Firefox feature can fix many issues by restoring your Firefox profile to its default state while saving your essential information.

1. Click this Refresh Firefox button directly, if you are viewing this page in Firefox. This won't work if you are using a different browser or a mobile device.
   • You can also find a Refresh Firefox button at the top of the Firefox about:supportTroubleshooting Information page.
2. To continue, click in the confirmation window that opens.
3. Firefox will close to refresh itself. When finished, a window will list your imported information. Click and Firefox will open.

Sometimes files in your Firefox profile folder that correspond to the essential information that a Firefox Refresh doesn't remove (such as bookmarks and browsing history) may be causing the issue. You can create a new, additional profile which will not contain any of your old Firefox data. See the Profile Manager - Create, remove, or switch Firefox profiles article for instructions.

If you've tried all of these troubleshooting methods and you're still having problems, here are some other solutions you can try:

Check browser internals

Telemetry Data shared with Mozilla (about:telemetry page) contains detailed data about performance, hardware, usage and customization. The Troubleshooting Information page (about:support page) includes other about: page links and troubleshooting resources. (For a list of all about: pages, enter about:about in the address bar.)

Some Internet security software (including antivirus, antispyware, and firewall programs) can cause problems with Firefox including blocking it from opening websites, crashes, and more. Often you can open the program's settings, remove Firefox from its list of allowed or trusted programs and it will be re-detected and things should start working again. If your program is listed at the Configure firewalls so that Firefox can access the Internet article, you can get specific instructions for how to properly reconfigure it.
