Anticipate the deprecation of Kernel extension #49

Deprecated Kernel Extensions and System Extension Alternatives

System extensions on macOS Catalina (10.15) allow software like network extensions and endpoint security solutions to extend the functionality of macOS without requiring kernel-level access. At WWDC19, we announced the deprecation of kernel extensions as part of our ongoing effort to modernize the platform, improve security and reliability, and enable more user-friendly distribution methods. Kernel programming interfaces (KPIs) will be deprecated as alternatives become available, and future OS releases will no longer load kernel extensions that use deprecated KPIs by default.

Transitioning Your Kernel Extensions

If your software uses deprecated and supported KPIs, you’ll need to factor out deprecated components into a stand-alone system extension. If your software uses new system extensions and legacy kernel extensions, you can distribute to supported operating systems. Software that supports a broad range of macOS versions should continue to use kernel extensions for older versions and run system extensions where supported.

Below is a list of deprecated KPIs as of macOS 10.15. In macOS 10.15.4, use of deprecated KPIs triggers a notification to the user that the software includes a deprecated API and asks the user to contact the developer for alternatives.

I'm not sure however how this can translate for NoSleep ?

I have not received a message about NoSleep.

The code has to be adapted to use DriverKit and then for its own distribution has to use an entitlement from Apple.

As far as I can tell, equivalents exist for this code to work. It just has to be ported.

And the kernel stops loading now on:

It's working for me.

You may need to System Preferences -> System and click on Allow in the General tab.

Indeed, it works, after starting it again for me, probably was some issue during system startup on my side. Sorry for the false-positive.

Thanks @Tatsh for the Allow hint!

I have the same problem as Viktor, but this occurs after 'Allowing' access in the Privacy & Security tab on MacOS Big Sur 11.6 (latest at today's date).

@sla797 has the right answer
