APPLE MAC CAC ENABLER (aka MIDDLEWARE) PAGE
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.
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.
Signing of PDFs should work in Mac OS Catalina (10.15.x) by adjusting these settings.
Mac users can now verify if their CAC is blocked by using the Apple
Smart Card Utility app
ONLY works for Mac OS 10.14 and later using 64-bit processor
ONLY works for Mac OS 10.14 and later using 64-bit processor
Follow Tables 1 through 4 below:
PLEASE READ the preliminary Information before you start:
Preliminary Information 1: Restart your computer after installing the CAC enabler before trying to access the CAC enabled site
Preliminary Information 2: Installing multiple enabling programs will cause your system to NOT work. Here's how to uninstall CAC enablers.
Preliminary Information 3: The CACkey CAC enabler will ask for a "keychain password" (like the image below). You need to enter your CAC PIN. Make sure if it asks for your Keychain password after you select your CAC certificate, that you use your CAC [6-8 digit / all number] PIN.
If you block your CAC, you'll have to visit an ID card
office to get it unblocked. PKard has the capability to show you when your CAC is blocked.
Mac OS 10.15.x and 10.14.x can download this app
to verify if their card is blocked:

Table 1: See which CAC enabling program will work with your version of Mac OS
Once you've decided, go to Table 2
Note2: Need version 1.7 (or above)
Note3: Apple computers with Mac OS Big Sur (Intel), Catalina, Mojave, High Sierra, and Sierra have a "built in Smart Card ability," meaning 3rd party CAC enablers are no longer needed. Please uninstall all CAC enablers you have installed
Note4: One person has informed me this works for him, but NOT when using Safari. Only using Chrome.
Note5: With Mac OS Sierra and High Sierra, you must use Google Chrome. Safari is not "CAC compatible." You may also update your computer to Mojave (or newer), then use Safari again.
Note6: Mac OS Catalina will not work with 3rd party CAC enablers installed. Please uninstall all CAC enablers you have installed. INFORMATION: There was an issue with 10.15.4. If this is the version you have, please update to 10.15.5 or above
Note7: I have a few reports that this enabler works with Mac OS Catalina
Table 2: Verify the CAC enabling program you selected above will work with your specific CAC.
Once you've decided, go to Table 3
Note1: I haven't heard of anyone with this CAC and specific enabler. If you have one and have successfully used your CAC with the question marked enabler above, please contact me
Note2: Will not work with Mac OS 10.15.7, works with previous versions
Table 3: Verify the CAC enabling program you selected in tables 1 & 2 is:
a. Compatible with Firefox (if you plan to use this web browser),
b. Will read your PIV Authentication certificate,
c. Will allow you to digitally sign PDFs,
d. Can show you when your CAC is blocked,
e. You want support from the vendor, or
f. You want it for free, or pay for it
Once you've decided, go to Table 4
and click the link to the CAC enabler you decided to use.
Note1: PIV cert has to already be exposed
Note2: Signing of PDFs on Mac OS Catalina (10.15.x), Mojave (10.14.x), High Sierra (10.13.x), & Sierra (10.12.x) can be corrected by following these settings. Some others have installed OpenSC and claim it works.

downloading this app (https://apps.apple.com/us/app/smart-card-utility/id1444710309?mt=12)
Mac OS native does not have this capability built in. Please know, it ONLY works for Mac OS 10.14.x
