I wonder if you have found a solution, I also encountered this problem。

Hi @jeff_f, @Drewbadour, I also encountered the same problem.Is there any conclusion? After this AD_HOC_CODE_SIGNING_ALLOWED user-defined variable is added, only "Sign to Run Locally" can be used, no entitlements can be added, so pcie dext still cannot be used. Is it possible to debug pcie dext only after requesting entitlements? I've made a Requesting, just let me follow up.

Hello, I also have the same question as you, asked if it has been solved, can you share the solution?

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
