Hello, sl149q Have you solve this problem? Cause i have similar problem. The RegisterEthernetInterface() call is returning a result of 0x3dcbd500 in Monterey. This code works correctly on both Catalina and BigSur, too. Any idea or suggestions would be welcome!!

Hi, Did you find the way to adding provisioning profile to a command line tool? Thanks

I already have entitlement about "com.apple.developer.driverkit.userclient-access". So in application can IOServiceOpen - https://developer.apple.com/documentation/iokit/1514515-ioserviceopen?language=objc and IOConnectCallMethod - https://developer.apple.com/documentation/iokit/1514240-ioconnectcallmethod?language=objc. I checked that works fine. But I can't use IOConnectSetNotificationPort - https://developer.apple.com/documentation/iokit/1514541-ioconnectsetnotificationport?language=objc method. DriverKit doesn't include registerNotificationPort - https://developer.apple.com/documentation/kernel/iouserclient/1400665-registernotificationport. So if I call IOConnectSetNotificationPort, return value is kIOReturnUnsupported.
