os x 10.9.4 ssl problems...

digicert_chat

/*
  I ran into a problem trying to go to https://github.com using Google Chrome
  where I'd get an ssl/security warning saying the certificate is not trusted.
  
  I tracked this down to an expired Digicert Certificate.
  
  After chasing around the web, one solution I saw was to reinstall the os x
  10.9.2 update. But that won't work, cuz I'm on 10.9.4.
  
  TL;DR: I chat w/ Logan over at Digicert... Boom. Fixed. Thanks Logan!

ryan:   [4:30:44 PM] is there a way to restore digicert certificates on os x 10.9.4? I accidentally deleted *all* of them.
Logan:  [4:30:48 PM] Hi Ryan!

Logan:  [4:31:17 PM] http://cacerts.digicert.com/DigiCertHighAssuranceEVRootCA.crt
        [4:31:44 PM] That is the only one you should need.
