Instantly Download Free Certificate Templates, Samples & Examples in Apple (MAC) Pages Format. Available in (US) 8.5x11. Quickly Customize. Easily Editable & Printable. Apr 10, 2013 Apple's Mac OS X includes a built-in key and password manager, Keychain, which stores user passwords, user and server certificates, and keys. Certain applications, including the Safari web browser, use this centralized Keychain for storing and retrieving certificate information in lieu of maintaining their own, separate certificate repositories.
Mac users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the built in smart card ability (very bottom of macuninstall link above)
If you purchased your Mac with OS Catalina (10.15.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
1. | Is your CAC reader 'Mac friendly'? |
2. | Can your Mac 'see' the reader? |
3. | Verify which version of Mac OS you have |
4. | Figure out which CAC (ID card) you have |
5. | Install the DoD certificates |
5a. | Additional DoD certificate installation instructions for Firefox users |
6. | Decide which CAC enabler you want to use (except for 10.12-.15) |
Step 1: Is your CAC reader Mac friendly?
Visit the USB Readers page to verify the CAC reader you have is Mac 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
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 'System Report...' (button)
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.
Step 2c1: 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, Proceed directly to step 3
Step 2c1a-SCR-331 reader
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 your firmware 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.
Step 2c1b-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 on most Macs. 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: Example: 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 top back of your ID card for these card types. If you have any version other than the six 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 5: Install the 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 the 5 files via links below (you may need to <ctrl> click, select Download Linked File As... on each link) Save to your downloads folder
Please know... IF You have any DoD certificates already located in your keychain access, you will need to delete them prior to running the AllCerts.p7b file below.
https://militarycac.com/maccerts/AllCerts.p7b,
https://militarycac.com/maccerts/RootCert2.cer,
https://militarycac.com/maccerts/RootCert3.cer,
https://militarycac.com/maccerts/RootCert4.cer, and
Double click each of the files to install certificates into the login section of keychain
Select the Kind column, verify the arrow is pointing up, scroll down to certificate, look for all of the following certificates:
DOD EMAIL CA-33 through DOD EMAIL CA-34,
DOD EMAIL CA-39 through DOD EMAIL CA-44,

DOD ID SW CA-45 through DOD ID SW CA-48,
DoD Root CA 2 through DoD Root CA 5,
DOD SW CA-53 through DOD SW CA-58, and
DOD SW CA-60 through DOD SW CA-61
NOTE: If you are missing any of the above certificates, you have 2 choices,
1. Delete all of them, and re-run the 5 files above, or
2. Download the allcerts.zip file and install each of the certificates you are missing individually.
Errors:
Error 100001 Solution
Error 100013 Solution
You may notice some of the certificates will have a red circle with a white X . This means your computer does not trust those certificates
You need to manually trust the DoD Root CA 2, 3, 4, & 5 certificates
Double click each of the DoD Root CA certificates, select the triangle next to Trust, in the When using this certificate: select Always Trust, repeat until all 4 do not have the red circle with a white X.
You may be prompted to enter computer password when you close the window
Once you select Always Trust, your icon will have a light blue circle with a white + on it.
The 'bad certs' that have caused problems for Windows users may show up in the keychain access section on some Macs. These need to be deleted / moved to trash.
The DoD Root CA 2 & 3 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
or | DoD Interoperability Root CA 1 or CA 2 | certificate | |
DoD Root CA 2 or 3 (light blue frame ONLY) | certificate | ||
or | Federal Bridge CA 2016 or 2013 | certificate | |
or | Federal Common Policy CA | certificate | |
or | or | SHA-1 Federal Root CA G2 | certificate |
