I encountered an issue when migrating to another Mac: the assistant didn't transfer the certificates. Here's how I resolved it: Access Apple Certificate Authority. Download the following certificates: Developer ID - G1 (Expiring 02/01/2027 22:12:15 UTC) Developer ID - G2 (Expiring 09/17/2031 00:00:00 UTC) Apple Inc. Root (if it's not already on your computer) For other certificates, I followed these steps on my old Mac: Open the certificate in Keychain Access. Find the intermediate certificates. Export and import them to the new Mac. For Apple certificates, I prefer to download them from the official site as mentioned above.

Until today, we got the same issue...
