CAC ON YOUR Mac INSTALL CHECKLIST PAGE
6 "high level" steps needed, follow down the page to make this a painless systematic process
Step 1: Is your CAC reader Mac friendly?
Visit the USB Readers page to verify the CAC reader you have is Mac friendly.
"Some, not all" CAC readers may need to have a driver installed to make it work.
NOTE: Readers such as: SCR-331, GSR-202, GSR-202V, & GSR-203 could need firmware updates (NO OTHER Readers need firmware updates).
Information about these readers are in Step 2
Step 2: Can your Mac "see" the reader?
Plug the CAC reader into an open USB port before proceeding, give it a few moments to install
Step 2a: Click the Apple Icon in the upper left corner of the desktop, select "About This Mac"
Step 2b: Click the "More Info" (button) (Mac OS 10.6.x and older), Mac OS 10.7.x and newer go to step 2c
Step 2c: Click "System Report..." (button) (Only shown in 10.7.x and newer)
Step 2d: Verify the CAC reader shows in Hardware, USB, under USB Device Tree. Different readers will show differently, most readers have no problem in this step. See Step 2d1 for specific reader issues.
Step 2d1: Verify firmware version on your SCR-331 or GSR-202, 202V, 203 CAC, or SCR-3500a reader. If you have a reader other than these 5, GO TO STEP 3
Step 2d1a-SCR-331 reader
If your reader does not look this this, go to the next step.
Below "Hardware" click "USB." On the right side of the screen under "USB Device Tree" the window will display all hardware plugged into the USB ports on your Mac. Look for “SCRx31 USB Smart Card Reader.” If the Smart Card reader is present, look at "Version" in the lower right corner of this box: If you have a number below 5.18, you need to update your firmware to 5.25. If you are already at 5.18 or 5.25, your reader is installed on your system, and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.
Step 2d1b-IOGear GSR-202, 202V, and 203 readers
If your reader does not look like these, go to Step 3.
Below "Hardware" click "USB." On the right side of the screen under "USB Device Tree" the window will display all hardware plugged into the USB ports on your Mac. You should see “EMV Smartcard Reader.” If the Smart Card Reader is present look for "Product ID" in the lower right corner of this box: If you see: 0x9540, you need to downgrade the firmware to 0x9520. If you see 0x9520, your reader is installed on your system, and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.
Step 2d1c-SCR-3500A reader
If you have the SCR3500A P/N:905430-1 CAC reader, you may need to install this driver, as the one that installs automatically will not work. Hold the control key [on your keyboard] when clicking the .pkg file [with your mouse], select [the word] Open
Step 3: Verify which version of MacOS do you have?
(You need to know this information for step 6)
Step 3a: Click the Apple Icon in the upper left corner of your desktop and select "About This Mac"
Step 3b: Look below Mac OS X for: Version 10.X.X.
Step 4: Figure out which CAC (ID Card) you have
(You need to know this information for step 6)
Look at the back of your ID card (above the black strip) for these card types. If you have any version other than the five shown below, you need to visit an ID card office and have it replaced. All CACs [other than these five] were supposed to be replaced prior to 1 October 2012.

Step 5: Update your DoD certificates (for Safari and Chrome Users)
Go to Keychain Access
Click: Go (top of screen), Utilities, double click Keychain Access.app
(You can also type: keychain access using Spotlight (this is my preferred method))
Select login (under Keychains), and All Items (under Category).
Download these 4 files (you might need to <ctrl> click, select Download Linked File As...) Save to your downloads folder
Double click each of the files to install certificates into the login section of keychain
The certificates that will be installed are:
DOD CA-27 through DOD CA-32,
DOD EMAIL CA-27 through DOD EMAIL CA-34,
DOD EMAIL CA-39 through DOD EMAIL CA-44,
DOD ID CA-33 through DOD ID CA-34,
DOD ID CA-39 through DOD ID CA-44,
DOD ID SW CA-35 through DOD ID SW CA-38,
DOD ID SW CA-45 through DOD ID SW CA-48, and
DoD Root CA 2 through DoD Root CA 4
Error 100001 Solution
Error 100013 Solution
You may notice 2 or 3 of the certificates will have a red circle with a white X . This means your Mac does not trust those certificates
You need to manually trust the DoD Root CA 3 & DoD Root CA 4 Root certificates
Double click DoD Root CA 3, select Trust, in the When using this certificate: select Always Trust, repeat for DoD Root CA 4
You may be prompted to enter computer password
Once you select Always Trust, your icon will have a light blue circle with a white + in it.
Some of the "bad certs" that have caused problems for Windows users now show up in the keychain access section on some Macs. These need to be deleted / moved to trash.
The DoD Root CA 2 you are removing has a light blue frame, leave the yellow frame version. The icons may or may not have a red circle with the white x
If you have tried accessing CAC enabled sites prior to following these instructions, please go through this page before proceeding
Clearing the keychain (opens a new page)
Don't forget to come back to this page to continue.
Step 5a: Additional DoD certificate installation instructions for Firefox users
Download AllCerts.zip, remember where you save it.
Click Firefox (word) (upper left of your screen)
Advanced (tab on left side of screen)
View Certificates (button)
Browse to the DoD certificates (AllCerts) you downloaded from link above.
Note: You have to do this step for each certificate (if anyone knows a way to automate this, please contact me)
Note2: If the certificate is already in Firefox, a window will pop up telling you it is already installed.
Note3: If the certificate is not already in Firefox, a window will pop up showing the image below to set the trust settings.
Check all three boxes to allow the certificate to: identify websites, identify email users, and identify software developers
Once you've added all of the certificates...
Step 6: Decide which CAC enabler you can / want to use
After installing the CAC enabler, restart the computer and go to a CAC enabled website
