Hello. This is Wakui from the Development Group 1.
This time, I would like to talk about the issue of APNs certificates not being trusted when created.
environment
MacOS version: Sonoma 14.4.1
Symptoms
When I tried to create an APNs certificate (.p12) as usual, I got a message saying that the certificate is not trusted in the keychain. It said "Not trusted" in red letters . How harsh!
Cause
When I looked at the keychain, the intermediate certificate was not included.
It's not included? Why? Come to think of it, this is slovakia email address the first time I've done this since I changed my work PC.
According to
The Apple Worldwide Developer Relations Certificate Authority issues the certificates used to sign software for Apple devices, which helps our systems verify that the software is delivered to users as intended and has not been altered.
I see. And according to the table in the link above, the intended use and certificate are linked depending on the intermediate version.
