On the computer Certificate 2016 2 15th invalid problem

1. 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 dare not all deleted, especially the enterprise certificate is not dry deleted, afraid before the application can not be used, ask the big God to see how this is going

2. Workaround:

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then click Certificates, in this interface, select the toolbar view---Show Expired certificates, you will find an outdated "WWDR Certificate "(Apple Worldwide Developer Relations Certification authority), delete it.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

   For reference! Thanks for sharing
