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 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.

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.

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.

If you own a Mac, you already have a high-resolution media file server at your disposal, with very little tweaking required to pass high-quality audio to your audio gear. I recently decided to set up my Mac in this way, to deliver hi-res throughout the signal chain--from my music library, to the player, to the DAC, to my preamp, amp, and loudspeakers (or preamp to headphones). Here is how I did it.

Building Your Hi-Res Music Library
The process starts with ripping or downloading music files directly to either your Mac's internal hard drive or an external drive, or designating a cloud site for your file storage (more on this in a minute). I store my music library on a 3TB Seagate external drive. Many people prefer to use an external drive because loading up your main hard drive with music files can potentially slow your computer's overall performance, especially when you get to the end of your drive's storage limits.

Opinions will vary on what constitutes hi-res audio, but I set my sights on resolutions equal to or better than 24-bit/96-kHz. We all know that your system is only as good as its weakest link, so I started with either 24/192 or 24/96 FLAC files. Hi-res files may be offered in the FLAC (Free Lossless Audio Codec) or AIFF (Audio Interchange File Format) format, as well as DSD (Direct Stream Digital) and MQA (Master Quality Authenticated). DSD is the Philips/Sony system used to create the SACD (Super Audio Compact Disk) format, while MQA is a very clever codec that compresses the relatively little energy in the higher frequency bands to make the files smaller while retaining a hi-res result (it's also a good format for streaming services). To get the highest quality, you will want to avoid lossy formats like MP3 (Moving Picture Experts Group Layer-3), AAC (Advanced Audio Coding), and OGG (Ogg Vorbis, the name Ogg derives from the jargon word ogging) that sacrifice audio quality for file size. This was important when storage was expensive, but now storage is plentiful and cheap.

Hi-res music files are available for download from a number of websites, including: HDTracks.com,
primephonic, HiRes Download, iTrax.com, B&W's Society of Sound, Acoustic Sounds, Chandos, and�Blue Coast Records. If you're looking for suggestions on high-quality audio recordings, check out the reviews on our sister site, AudiophileReview.com. Here are a few great-sounding albums (all available as hi-res downloads) that I'd put on my list of desert island discs:

Santana: Abraxas
Mozart: Great Mass in C minor
