Skyfall

Experimental macOS Tahoe support

Compatible models:

MacBookPro13,1 (Sppofed iGPU, 13,2 - No T1 support! 13,3 - No T1 and dGPU support!)
MacBookPro14,1 (14,2 - No T1 support! 14,3 - No T1 and dGPU support!)
MacBook9,1 (Spoofed iGPU)
MacBook10,1
iMac17,1 (Spoofed iGPU, no dGPU support! No Fusion drive support! Upgrade to an SSD!)
iMac18,x - 19,x (No Fusion drive support! Upgrade to an SSD!)

Graphics patches for Non-Metal, Legacy Metal and patches for T1 and T2 Macs are not supported

Note

Other Macs may be supported (the program doesn't block them and still probably creates a working OpenCore config), newer Macs have the T2 chip and they can't boot macOS via OpenCore. Older Macs do not support Metal 3 (so no graphics acceleration), 2016 Skylake Macs without dGPUs are partially supported with GPU spoofing. Your mileage may vary!

You may also enable untested Root Patches, they probably won't work or they may break your macOS install. Proceed with caution!

Building EFI form Windows

Example build command for building OpenCore for MacBookPro14,1:

.\.venv\Scripts\python -c "from skyfall.application_entry import main; main()" --build --model MacBookPro14,1

Non-functional features

• On majority of patched Macs, iPhone Mirroring and Apple Intelligence won't be functional.

  • iPhone Mirroring requires T2 for attestation and Apple Intelligence requires an NPU only found in Apple Silicon.
  • The patcher is unable to provide a fix for these as they're hardware requirements.

Tested Root Patches:

Wireless & Continuity Restoration

Restores full functionality for Broadcom-based wireless chipsets found in most 2009 - 2017 Macs (BRCM4360/4350 and BCM943224/94331)

PCIe webcam

Restores full functionality for PCIe webcams found in non-T2 Macs.

Modern Audio (AppleHDA Restoration)

Restores the AppleHDA.kext. Works for all non-T2 Macs that had native audio in Sequoia. Requires the KDK.

• Manual Toggle: A new "Modern Audio" toggle in the Root Patches menu allows you to enable or disable this restoration manually.
• KDK Integration: Automatically handles the necessary Kernel Debug Kit (KDK) requirements for audio driver linking.

Build and run from source

Installation Requirements

Before Running Post-Install Patches: KDK is mandatory: For macOS 13 through Tahoe (26.x), the Kernel Debug Kit must be installed for drivers like AppleHDA to link correctly. Use the Help > Download KDK button.

Root Volume Dirty Error: If the patcher detects that the system volume has been modified (e.g., patches already applied or seal broken), it will block further patching to prevent system instability.

• To re-patch: You must first use the "Revert Root Patches" button to restore the original system state.
• If no manifest is found: If the volume is modified but the patcher cannot find a record of what was installed, it will display a "Root volume is modified" error. In this case, you should still attempt a "Revert Root Patches" or reinstall macOS to clean the volume.

Advanced: Manual Force Restore (Emergency only)

If the "Revert Root Patches" button fails to clear the dirty state, you can manually force macOS to boot from the last sealed snapshot via Terminal:

sudo bless --mount /Volumes/YourVolumeName --bootefi --last-sealed-snapshot

Replace YourVolumeName with your actual system drive name (e.g., Macintosh\ HD).
