How to Fix "usr/standalone/OS.dmg.root_hash" Error When Booting macOS Tahoe Recovery

This error occurs when the OpenCore boot process cannot locate the root hash file required to verify the Recovery DMG. It typically affects macOS Tahoe recovery images on Hackintosh systems.

Step-by-Step Fix:

  1. Update OpenCore: Ensure you are running the latest version of OpenCore (0.9.9+). Tahoe requires recent changes to the boot process. Download from the official repository.
  2. Set SecureBootModel: In your config.plist, navigate to Misc → Security → SecureBootModel and set it to Disabled for initial installation. The log shows x86legacyap — this may conflict with Tahoe's requirements.
  3. Enable Vault: Set Misc → Security → Vault to Optional.
  4. Use a full installer: Instead of Recovery, create a full macOS Tahoe installer USB using createinstallmedia. Recovery mode for Tahoe may have issues with root hash verification on non-Apple hardware.
  5. Check your boot args: Your current args include -wegnoigpu revpatch=sbvmm. Ensure WhateverGreen and RestrictEvents kexts are up to date.
  6. Reset NVRAM: From the OpenCore picker, select Reset NVRAM and try booting again.

Important: macOS Tahoe on unsupported hardware is experimental. Expect issues. Always keep a working backup of your current macOS installation.
