Error when installing system extension

<Security`Security::CodeSigning::Requirement::Interpreter::eval(int)> sysextd: (Security) [com.apple.securityd:SecError] Error checking with notarization daemon: 3

<sysextd> sysextd: bundle code signature is not valid - does not satisfy requirement: -67050

Hello, when our customer is trying to install our product on his computer with bigsur 11.6 build 20G165, system denies our system extension with the errors mentioned above. Extension verification then ends with error 8 (signature invalid).

This extension however installs without any issues on other machines, and it is correctly signed and notarized.

Could you please provide some info about these errors? specifically [com.apple.securityd:SecError] Error checking with notarization daemon: 3 and error NSOSStatusErrorDomain Code=-67050

Thank you, Jakub

Those errors suggest that the system is unable to check that your product is notarised. Given that your product is notarised, the issue is clearly on the client side. It’s best to start teasing apart the potential factors here. First, have you tried installing your product on a ‘clean’ macOS 11 machine? Here’s how I do this: Testing a Notarised Product.
