APPLE COMPUTER - HOW TO CLEAR THE LOGIN SECTION OF KEYCHAIN
If you have problems accessing websites with your CAC please try the following ideas.
Ideas 1, 2, & 3 are for Safari users
NOTE: If you are using the Mac OS Sierra built in Smart Card ability, this page will be of no use to you
Idea #1: Manually delete the websites you are having problems accessing.
This also helps if you lost access [for no apparent reason] to any sites you access with your CAC.
Step 1-1: Click: Go (top of screen), Utilities, double click Keychain Access.app
(You can also type: keychain access using Spotlight (this is my preferred method))
Step 1-2: Select login (under Keychains), and All Items (under Category) see image below. You will see all items that are being saved in your Keychain Access. These can include your Airport password for your home Wi-Fi network and / or CAC websites / Identity preferences that you have visited and used your CAC on previously.
Step 1-3: Click the column heading titled Kind, scroll down to Identity preference, Delete all CAC enabled websites you are having problems accessing. You can hold your control key and click your single button Mac mouse and select Delete, or if you have a two button mouse right click and select Delete.
Example of mail.mil entries to remove. You will see something different than "mont."
NOTE: Yours will probably have a red circle with a white X
Some of the same "bad certs" that have caused problems for Windows users are showing up in the keychain access section on 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
Once the certificates above are deleted, close keychain
Step 1-4: Remove CAC from reader
Step 1-5: Clear your web browser history, then revisit the CAC website you were having problems accessing.
Step 1-5a: Click on the word Safari, followed by Clear History...
Step 1-5b: Select all history in the Clear (dropdown box), and select the Clear History (button) select the Clear History (button)
Step 1-5c: Click the word Safari again, now Preferences...
Step 1-5d: Click the Privacy (tab), then Manage Website Data... (button)
Step 1-5e: Type mail.mil [or other sites you are having problems accessing] into the search box (upper right side of active window)
Step 1-5f: Once / if items populate in the window, select it / them, click Remove / Remove All, then Done to close the window
Step 1-5g: Reinsert your CAC in your reader and try accessing the CAC enabled website again.
NOTE: If you accidently delete the login folder rather than the items inside it, you can restore it by navigating to /users/<username>/library/keychains/login.keychain and double clicking it.

Idea #2: You may have a corrupt preference.
Open Safari, click the word Safari, Reset Safari... this will clear out cached pages
Further ideas can be seen on Apple Support
Idea #3: Clearing the old certificates (after receiving a new CAC)
The Mac OS will cache some information about your CAC in
order to read the data faster the next time it's being used on your
computer. Sometimes this cache can cause issues after receiving a new
ID card. Thursby's suggestion is that you remove your card from the
reader, download the utility from the link below, then
run the app for "if you have received a new card or new certs." This
will clear all of the token cache information by running a Terminal
command. There will not be a completion dialog, and
you may be prompted to type in your computer password.
If you feel comfortable using command line, you can Run in Terminal.app:
sudo rm -rf /var/db/TokenCache/tokens/
Instructions "borrowed" from this page
Firefox does not use the keychain access, it stores the files within the web browser. Here is how to clear them:
1. Select the 3 equal lines (upper right corner of your Firefox web browser).
2. Select: Preferences
3. Select: Advanced
4. Select: Certificates
5. Select: View Certificates
6. Select: Servers
7. Scroll down to: U.S. Government
8. Select the certificates you want removed, then click Delete...

The five current CAC "models" are: "GEMALTO TOP DL GX4 144", "GEMALTO DLGX4-A 144", "Oberthur ID One 128 v5.5 Dual", "Oberthur ID One 128 v5.5a D", and
"G&D FIPS 201 SCE 3.2."
You can verify by looking on the back of your ID card above the black magnetic strip for either of these:
