Installing Apple’s Updated Intermediate WWDR Certificate

On February 14th, 2016, the original Apple’s Intermediate WWDR certificate expired. To make sure you can keep building locally, and using buddybuild’s certificate uploader tools, you should make sure you have the latest version of the intermediate certificate.

If you see something like this in Keychain, then the problem affects you.

Download and install the new certificate

Go to https://www.apple.com/certificateauthority/ and download the certificate marked WWDR Certificate (Expiring 02/07/23).

Once you have downloaded that, double click on it to install it.

Remove any copies of the old certificate

Simply installing the new certificate is not enough. You must remove copies of the old one too.

By default, Keychain does not show expired certificates, which makes them had to find.

Go to View and make sure you have clicked Show Expired Certificates.

The Keychain View menu, with 'Show Expired Certificates' selected

Then look for Apple Worldwide Developer Relations Certification Authority in both the login and System keychains. You will see the red expired cross next to it. Delete it from both.
