Hi,we have a KEXT-enabled Developer ID which we are using for code signing and I have verified that the certificate contains the 1.2.840.113635.100.6.1.18 extension required. However, kextutil -tn still shows:Untrusted kexts are not allowed Kext with invalid signature (-67050) denied: /Library/StagedExtensions/Library/Extensions/A0587A5A-52FC-46DC-832E-81919195902C.kextAfter signing, I also extracted the signature using the instructions here to verify that the correct kext-enabled Developer ID certificate was used during the signing process.I have "Apple Worldwide Developer Relations Certification Authority" and "Developer ID Certification Authority" certs in both the login and System keychains.Where do I go from here?Thanks!
