2016 certificate invalid, look here

Just came back to work, encountered such a problem:

1. Describe your problem
   On the first day of work, found that the certificate on the computer prompt: "The issuer of this certificate is invalid" and Enterprise version packaging is an error, but do not dare to delete, especially the Enterprise certificate does not delete, afraid before the application can not be used, ask the big God to see how this is going!

2. Paste the relevant code

3. Post error message

====================================================================

1, follow your link to download, Https://developer.apple.com/certificationauthority/AppleWWDRCA.cer, and install.

2, select Login in Keychains, then click Certificates, in this interface, select the toolbar view---Show Expired certificates, you will find an outdated "WWDR Certificate "(Apple Worldwide Developer Relations Certification authority), delete it.

3, in the system of the column also has this expired "WWDR Certificate", and delete it.

4, no accident your certificate there from "This certificate have an invalid issuer" (the issuer of this certificate is invalid) becomes "This certificate is valid".

That's how I solve it.
