To get started you will need:
1. Common access card (CAC)
2. Card reader
NGA recommends you use the latest Mac operating system (OS) version (currently Ventura). To start using your CAC, follow these basic steps:
1. Get a card reader. Note: Macs do not typically come with card readers; therefore an external card reader is needed. NGA recommends the SCR3310v2 card reader.
2. Acquire USBC to USB Adapter.
3. Plug in your card reader to the adapter. Note: You may receive a pop-up (shown below). If so, select Allow.
