If you have a Common Access Card (CAC), you can use it to sign into your Mac. This will allow you to access military websites and email, as well as other government resources. In order to sign in with your CAC, you'll need to have the following:
- A CAC reader that's compatible with your Mac
- The latest version of the DoD Root Certificate
- Your CAC card and PIN
Once you have everything set up, follow these steps:
1. Plug your CAC reader into your Mac's USB port.
2. Launch the Safari web browser.
3. Go to the website that you want to access using your CAC card. For example, if you want to check your military email, go to https://webmail.usmc.mil/. If prompted, select Use Military Certificates. You may also be prompted to enter your PIN at this point. 4. When prompted, select the DoD Class 3 PIV Certification Authority certificate from the list of certificates on your computer. 5. Enter your PIN when prompted and click OK. You should now be signed in and able to access the website or resource that you were trying to reach using your CAC card
