This morning my colleague said that our certificate was unusable, and that "the issuer of this certificate is invalid" is displayed. At the beginning of the thought of who mistakenly operated the certificate, the review found that all certificates are invalid.

It was the Apple worldwide Developer Relations Certification Authority Intermediate Certificate certificate just expired today.

1. To download the latest certificate on the Apple PKI webpage: https://developer.apple.com/certificationauthority/AppleWWDRCA.cer, double-click Import.

2. First open your own keychain, delete the original expired WWDR certificate. (I have deleted and updated it here.)
   

Note: Remove after installation.

Now that the certificate is invalid, everything is OK.
