As per earlier this week, we've been notified that Apple has removed the ability for OpenCore Legacy Patcher to automatically download Kernel Debug Kits from Apple's Developer Site.

This change was caused by Apple limiting available items available through the same system Xcode uses to download support packages. Now the system is primarily applicable for watchOS and tvOS Simulator downloads, and not for general items.

The reason OCLP need this system is that Apple currently locks Kernel Debug Kit downloads to users with signed in Apple IDs on the Developer Portal, limiting automated support from our perspective.

Due to this, AMD GCN 1-3 Macs on macOS Ventura can no longer root patch without manually installing a Kernel Debug Kit. If you wish to root patch on macOS Ventura with an applicable Graphics Card, you'll need to manually download and install a Kernel Debug Kit.

• https://developer.apple.com/download/all/?q=kernel%20debug%20kit
  • Choose the closet match to your OS

Once downloaded, mount the disk image and run the KernelDebugKit.pkg:

Once installed, OCLP should automatically see the Kernel Debug Kit and continue patching.

Currently no time estimate can be provided for a work-around to be implemented in OpenCore Legacy Patcher.
