Between mid October 2019 and mid February 2020 everyone in the Army was migrated to use their PIV Authentication certificate for Email access. You no longer use the Email certificate for Enterprise Email or any CAC enabled websites

Mac users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x), Big Sur (11.xx.x), or Monterey (12.x.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the native smart card ability (very bottom of macuninstall link above)

If you purchased your Mac with OS Catalina (10.15.x) or Big Sur (11.xx.x) already installed, you can skip the uninstall part above and follow the instructions below.

6 "high level" steps needed, follow down the page to make this a painless systematic process

MilitaryCAC's Mac OS OS Installation Steps Page (1)

Step 1: Is your CAC reader Mac friendly?

Visit the USB Readers page to verify the CAC reader you have isMac friendly.

Visit the USB-C 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 & SCR-3500A may need a firmware update (NO OTHER Readers need firmware updates).

Information about these specific readers are in Step 2

MilitaryCAC's Mac OS OS Installation Steps Page (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"

MilitaryCAC's Mac OS OS Installation Steps Page (3)

Step 2b: Click "System Report..." (button)

MilitaryCAC's Mac OS OS Installation Steps Page (4)

Step 2c: 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 2c1 for specific reader issues.

MilitaryCAC's Mac OS OS Installation Steps Page (5)

Step 2c1: Verify firmware version on your SCR-331, SCR-3310 v2.0, GSR-202, 202V, 203, or SCR-3500a reader. If you have a reader other than these 6, Proceed directly to step 3

Step 2c1a-SCR-331 reader

MilitaryCAC's Mac OS OS Installation Steps Page (6)

If your reader does not look like this, go to the next step.

In the "Hardware" drop down, 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 5.25, you need to update yourfirmware to 5.25. If you are already at 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.

MilitaryCAC's Mac OS OS Installation Steps Page (9)

If your reader does not look like this, go to the next step.

In the "Hardware" drop down, 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 “SCR3310 v2.0 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 6.02, it will not read the "G+D FIPS 201 SCE 7.0" or the "GEMALTO DLGX4 128Kv2" CACs on Mac OS 10.15.7 or newer. I contacted HID (the company that makes these readers) on 14 DEC 2020 to find a way to update the firmware to 6.02. They said there is not firmware update for the reader. If your reader is older, you may need a new one. Please look at:https://militarycac.com/usbreaders.htm to find a compatible one. If you are already at version 6.02, your reader should work fine on your Mac and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.

Step 4: Figure out which CAC (ID Card) you have

(You need to know this information for step 6)

Look at the top back of your ID card for these card types. If you have any version other than the seven shown below, you need to visit an ID card office and have it replaced. All CACs [other than these six] were supposed to be replaced prior to 1 October 2012.

Step 5a: DoD certificate installation instructions forFirefox users

NOTE: Firefox will not work on Mac OS 10.12.x or newer when using the native Apple smartcard ability

Firefox also requires the installation of CACKey and configured to use it.

Download AllCerts.zip, [remember where you save it].

double click the allcerts.zip file (it'll automatically extract into a new folder)

Option 1 to install the certificates (semi automated):

From inside the AllCerts extracted folder, select all of the certificates

<control> click (or Right click) the selected certificates, select Open With, Other...

In the Enable (selection box), change to All Applications

Select Firefox, then Open

You will see several dozen browser tabs open up, let it open as many as it wants..

You will eventually start seeing either of the 2 messages shown next

If the certificate is not already in Firefox, a window will pop up stating "You have been asked to trust a new Certificate Authority (CA)."

Check all three boxes to allow the certificate to: identify websites, identify email users, and identify software developers

MilitaryCAC's Mac OS OS Installation Steps Page (44)

or

"Alert This certificate is already installed as a certificate authority." Click OK

MilitaryCAC's Mac OS OS Installation Steps Page (45)

Once you've added all of the certificates...
• Click Firefox (word) (upper left of your screen)
• Preferences
• Advanced (tab)
• Press Network under the Advanced Tab
• In the Cached Web Content section, click Clear Now (button).
• Quit Firefox and restart it

MilitaryCAC's Mac OS OS Installation Steps Page (46)

Note3: If the certificate is not already in Firefox, a window will pop up stating "You have been asked to trust a new Certificate Authority (CA)."

Check all three boxes to allow the certificate to: identify websites, identify email users, and identify software developers

MilitaryCAC's Mac OS OS Installation Steps Page (47)

Once you've added all of the certificates...
• Click Firefox (word) (upper left of your screen)
• Preferences
• Advanced (tab)
• Press Network under the Advanced Tab
• In the Cached Web Content section, click Clear Now (button).
• Quit Firefox and restart it

MilitaryCAC's Mac OS OS Installation Steps Page (48)

Step 6: Decide which CAC enabler you can / want to use

Only for Mac El Capitan (10.11.x or older)

https://militarycac.com/cacenablers.htm

After installing the CAC enabler, restart the computer and go to a CAC enabled website

NOTE: Mac OS Sierra (10.12.x), High Sierra (10.13.x), Mojave (10.14.x), Catalina (10.15.x), Big Sur (11.x), and Monterrey (12.x) computers no longer need a CAC Enabler.

REMINDER: Users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x), Big Sur (11.xx.x), or Monterey (12.x.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the native smart card ability (very bottom of macuninstall link above)

Try to access the CAC enabled site you need to access now.

MilitaryCAC's Mac OS OS Installation Steps Page (49)

If you have problems, please follow images below to verify if your CAC is being read by your computer

Click the Apple Icon in the upper left corner of the desktop, select "About This Mac"

MilitaryCAC's Mac OS OS Installation Steps Page (50)

Click the "System Report..." button

MilitaryCAC's Mac OS OS Installation Steps Page (51)

Scroll down the left column to the "Software" section then click on "SmartCards"

MilitaryCAC's Mac OS OS Installation Steps Page (52)

If you see hundreds of lines of "gibberish" these are your certificates being read from your CAC.

MilitaryCAC's Mac OS OS Installation Steps Page (53)

Example of CAC not being read. You'll only see roughly15 lines of text.

MilitaryCAC's Mac OS OS Installation Steps Page (54)

If this is what is happening to you, it could mean your CAC reader needs a driver or firmware update. Look for your reader on theCAC readers page to verify if your reader and CAC combination is compatible with each other.

REMINDER: Users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x), Big Sur (11.xx.x), or Monterey (12.x.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the native smart card ability (very bottom of macuninstall link above)
