# KdkSupportPkg

Repository dedicated to Kernel Debug Kit archival, with primary focus on macOS Ventura KDKs in relation to Root Volume Patching with OpenCore Legacy Patcher.
Repository dedicated to Kernel Debug Kit archival, with a primary focus on macOS Ventura KDKs in relation to Root Volume Patching with OpenCore Legacy Patcher.

----------

With macOS 13, Ventura, Apple dropped on-disk kernel binaries in `/System/Library/Extensions`. Due to this, end users cannot build Boot and System Kernel Collections without manually install a Kernel Debug Kit from Apple's Developer Site. However due to Apple's account requirement for downloads, automated retrival is not possible. Thus this repo will create a release for each KDK seeded, with the tag representing the build associated.
