Hi Developer Community, I'm encountering persistent code signing failures on macOS Sonoma 15.3 with a valid Developer ID Application certificate. The error occurs consistently across multiple certificate regenerations and various troubleshooting approaches. Environment macOS Version: Sonoma 15.3 Developer Account Type: Developer ID Certificate Type: Developer ID Application Certificate Details: Developer ID Application certificate valid until 2027 Using SHA-256 with RSA Encryption Certificate shows as valid in Keychain Access with associated private key Error Message Warning: unable to build chain to self-signed root for signer "Developer ID Application: [my certificate]" [filename]: errSecInternalComponent Steps to Reproduce Install certificate chain in order: Apple Root CA (System keychain) Apple WWDR CA (System keychain) Developer ID CA (System keychain) Developer ID Application certificate (Login keychain) Verify certificate installation: security find-identity -v -p codesigning Result shows valid identity.

Any suggestions for resolving this system-level certificate trust chain issue would be greatly appreciated. Thanks in advance!

I just got an approval for my app. I loaded it on my iPhone - and it won't open. It goes to flash screen and then back to my phone Home Screen?? Anyone have ideas?
