Notarization Rejects Valid Developer ID Certificates - Apple Infrastructure Issue?
Environment
macOS: 15.6.1
Xcode: 26.0.1
Architecture: arm64 (Apple Silicon)
Team ID: W----------
Certificate Status: Valid until 2030 (verified on developer.apple.com)
Problem
Apple's notarization service consistently rejected properly signed packages with error:
"The binary is not signed with a valid Developer ID certificate."
Despite:
✅ Valid certificates on developer.apple.com
✅ Local signing succeeds (codesign --verify passes)
✅ Proper certificate/key pairing verified
✅ Package structure correct
Failed Submission IDs

What I've Tried
Re-downloaded fresh certificates from Apple Developer Portal
Verified certificate chain locally
Tested with multiple different builds
Confirmed Team ID matches across all configurations
Verified no unsigned nested components
Waited 3 months for potential propagation delays
Verified all agreements are current and accepted
Re-tested with minimal test package - same error persists
Local Verification
# Certificates present and valid
security find-identity -v -p codesigning | grep "Developer ID"
1) XXXXXXXXXX "Developer ID Application: <<REDACTED>> (W----------)"
2) XXXXXXXXXX "Developer ID Installer: <<REDACTED>> (W----------)"
# Signing succeeds
codesign --verify --deep --strict --verbose=2 [app] → Success
Question
This appears similar to thread #784184. After 3 months and ensuring all agreements are signed, the issue persists with identical error.
The certificates work for local signing but Apple's notarization service rejects them. Could this be:
Backend infrastructure issue with Team ID W----------?
Certificate not properly registered in Apple's notarization database?
Known issue requiring Apple Support intervention?
Has anyone else experienced valid Developer ID certificates being rejected specifically by the notarization service while working locally?
