OpenCore Legacy Patcher 3.1.6 - Tahoe Patch Set (YBronst)

This project continues the Tahoe patch set based on commit lzhoang2801 from December 24, 2025, and adapts it to the new macOS Tahoe environment.

Important Compatibility Notice

This repository supports:

• macOS Tahoe 26.0 – 26.3
• Support for macOS Tahoe 26.4 and later will be implemented as soon as possible

Important

Starting with macOS 26.4 beta 1, Apple made significant changes to the system update process. The previous Tahoe update process cannot function without modifications in these versions.

In particular:

• Previous handling of HFS-based patch images is no longer accepted by the OS.
• Mounting images via hdiutil now requires elevated privileges and cannot be executed in a normal user context. Because of this, the original OCLP 3.0.0 Nightly workflow cannot complete the root patch installation process on macOS 26.4 without modification.

Key Changes in 3.1.6

Added a toggle to the 'Root Patches' sector to enable/disable the 'Modern Audio' patch for AppleHDA restoration. This prevents unrecoverable kernel panics in macOS Tahoe without an installed KDK.

Key Changes in 3.1.5

• Backward compatibility with macOS Tahoe 26.0–26.3 has been preserved.
• Patch image processing has been migrated to APFS for compatibility with macOS 26.4.
• Privileged mount logic has been added, which is necessary for accessing internal patch images and system resources.
• AMFIPass cannot be used with OCLP 3.1.5 due to a persistent kernel panic. Instead, use amfi=0x80 boot argument and handling application permissions based on tccplus.

Modern Audio (AppleHDA)

On macOS 26.4 beta 1, installing the Modern Audio patch is temporarily not recommended until the corresponding kernel debug kit (KDK) becomes available.

For systems requiring a fully functional reference environment (including sound) on macOS 26.3 and earlier, I recommend a saved and working patch snapshot from December 24th, available here: OCLP-lzhoang2801

Note: This patch set still requires the amfi=0x80 boot argument.
