Instructions for approving a self-signed certificate in Chrome on Mac


First of all, I got this from here, so all credits go there.

On Mac, Chrome uses the system keychain for certificate lookup, so we need to add it there.  Here’s how:

  1. In the address bar, click the little lock with the X. This will bring up a small information screen. Click the button that says “Certificate Information.”
  2. Click and drag the image to your desktop. It looks like a little certificate.
  3. Double-click it. This will bring up the Keychain Access utility. Enter your password to unlock it.
  4. Be sure you add the certificate to the System keychain, not the login keychain. Click “Always Trust,” even though this doesn’t seem to do anything.
  5. After it has been added, double-click it. You may have to authenticate again.
  6. Expand the “Trust” section.
  7. “When using this certificate,” set to “Always Trust”

That’s it! Close Keychain Access and restart Chrome, and your self-signed certificate should be recognized now by the browser.

    Doesn’t work for me. I still get the yellow warning page in Chrome.

      did you do (4) correctly? what does the warning say exactly, which error do you see?

    The icon is not draggable for me. Is there another way to save that certificate file?

      Not that I’m aware of, but perhaps it’s a permissions issue? Are you sure you are dragging the correct image?
