Can you tell me how to use IODMACommand to avoid this problem? I also encountered the same problem？

Hello, I am also experiencing the same issue. Do I need to use the "Apple Develop Program" and use the correct certifications to use correctly on MacOS M1/M2? Does it have to be notarized?

Thank you for your reply. Our PCIE products do require Mac OS drivers. The os_log function can see the log in the console app when writing the application layer app. But when the os_log is written in the io_kit driver, it cannot be viewed. I want to debug the driver according to the log information, so that the development can be faster
