CAC ON YOUR Mac INSTALL CHECKLIST PAGE

 

NOTE:

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.

 

New imageMac 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.New image

 

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"

About This Mac imae

 

Step 2b:  Click the "More Info" (button) (Mac OS 10.6.x and older),  Mac OS 10.7.x (and newer) proceed to step 2c

About This Mac image

 

Step 2c:  Click "System Report..." (button)  (Only shown in 10.7.x and newer)

Secondary About This Mac image

 

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. 

SCR-331 firmware version verification image

 

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, Proceed directly to step 3

 

Step 2d1a-SCR-331 reader

Picture of SCR-331 USB CAC 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 5.18, 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-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"

About This Mac imae

 

Step 3b:  Look below Mac OS X for:  Example: Version 10.X.X.

OS X version

 

 

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.
