Could Apple be upfront with their policy if Apple decided against publishing macOS KDKs?I can't make another conclusion from missing KDKs for the latest builds and delays it took to publish KDKs for the old builds.10.15.4 KDK for release build has not been published.10.15.5 beta KDK is missing as well.

Hi,Can somebody confirm that it is not possible to add a 3rd party KEXT to a prelinked kernel on systems with the T2 chip and active safeboot mode?I need an IOKit object being probed against a device nub as early as possible. This requires a KEXT to be added to a prelinked kernel hosted at /System/Library/PrelinkedKernel . I noticed that the system uses /System/Library/PrelinkedKernel/immutablekernel instead of /System/Library/PrelinkedKernel/prelinkedkernel if safeboot is active and the system has the T2 chip . The immutablekernel file is protected by the UEFI boot module which checks a prelinked kernel signature saved at the Preboot volume so there is no way to modify it with the kextcache command.The existing procedure when a 3rd party KEXT is being loaded by the kextd process after the system has been initialized might not be the best solution in my case.Is there a procedure for a 3rd party KEXT to be linked with immutablekernel or change the system behavior to load /System/Library/PrelinkedKernel/prelinkedkernel in safeboot mode?
