Notarization Rejection - The binary is not signed with a valid Developer ID certificate

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

What I've Tried

  1. Re-downloaded fresh certificates from Apple Developer Portal
  2. Verified certificate chain locally
  3. Tested with multiple different builds
  4. Confirmed Team ID matches across all configurations
  5. Verified no unsigned nested components
  6. Waited 3 months for potential propagation delays
  7. Verified all agreements are current and accepted
  8. 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?
