I have a binary which I have signed with a valid developer certificate.
Here is how I verify the signature was correctly applied:
% codesign -dvv ./test_program.exe
Executable=/Users/REDACTED/code_signing/test_program.exe
Identifier=com.REDACTED.hello_world
Format=Mach-O thin (arm64)
CodeDirectory v=20500 size=489 flags=0x10000(runtime) hashes=9+2 location=embedded
Signature size=9071
Authority=Mac Developer: REDACTED NAME (REDACTED_ID)
Authority=Apple Worldwide Developer Relations Certification Authority
Authority=Apple Root CA
Timestamp=Apr 16, 2025 at 11:26:43 AM
Info.plist=not bound
TeamIdentifier=REDACTED
Runtime Version=14.2.0
Sealed Resources=none
Internal requirements count=1 size=192
==============================
Additionally, I have confirmed in keychain access that my certificate is valid. Here is the output from the GUI:
Issued by: Apple Worldwide Developer Relations Certification Authority
Expires: Wednesday, April 15, 2026 at 3:50:14 PM Eastern Daylight Time
This certificate is valid
==============================
When I zip then send the executable for notarization, I get an "Invalid" response. Here is the log from that response:
% xcrun notarytool submit ./test_program.zip --keychain-profile REDACTED --wait

And here is the log indicating the reason for the notarization failure:

}
==============================
The notarization server saying that it's not signed by a valid developer certificate, but to the best of my ability I have confirmed that a valid developer certificate is being used.
