While beta testing El Capitan, I notice that HTTPS pages, like Facebook, are not opening in Safari or Chrome. Any ideas as to how to go about this?

The HTTPS issue is likely because of antivirus software running (particularly Norton or Avast). They have caused this issue for others. You may need to remove it completely, but first you can try disabling firewall blocking of applications and connection blocking (or just temporarily disabling its "shields" if it's Avast!). After a restart you should be able to connect to Facebook etc. as normal; some have even found that they can re-enable their antivirus afterwards to no ill effect.


If you don't have antivirus installed then it's probably a root certificate issue. You can check (and fix) that by:


  • Open Keychain (by pressing CMD+Space and then typing “Keychain”).
  • Then type veri into the Keychain app's searchbar.
  • For each of the VeriSign certificates, do the following:
    • Check that the certificate is still valid (far right column) and delete it if it isn't.
    • Double-click it, which brings up it's own window and expand the "Trust" menu.
    • Make sure "When using this certificate:" is set to "Use System Defaults", not "Always Trust".
      • The remaining 10 should be left at "no value specified".
