Verify whether the Mac is actually reading the CAC

macos

Symptoms

Unsure whether the failure is at the reader, the card, or the browser.

Likely cause

Diagnostic check, not a defect.

Fix

1. Click Apple > About This Mac > System Report. 2. In the left column, scroll to Software > SmartCards. 3. If hundreds of lines of token info appear, the card IS being read - the problem is downstream (certs, browser, keychain). 4. If you only see ~15 lines, the card is NOT being read - check the reader on militarycac.com/usbreaders.htm, verify the card type, swap USB ports, and restart.
