Intel NUC 8i7BEH (Bean Canyon) macOS Tahoe 26.5.1 Hackintosh

English | 简体中文

This project is based on OpenCore 1.0.8 and perfectly supports running macOS Tahoe (26.5.1) on an Intel NUC 8i7BEH mini-PC.

This configuration references and pays homage to the classic project Nucintosh, and has been deeply adapted and optimized for macOS Tahoe (26.x) systems, removing the native sound card driver (AppleHDA) and requiring the wireless network card to connect via itlwm + HeliPort.

🛠️ macOS Tahoe Special Configuration Notes (Must Read)

Starting with macOS Tahoe (26.x), Apple removed the AppleHDA.kext driver used by older Macs. To ensure the built-in sound card and wireless network card drivers function perfectly on Tahoe, this project implemented the following critical security downgrade configurations in config.plist:

1. Disable Secure Boot: SecureBootModel is set to Disabled.

• Reason:* This is a prerequisite for using OCLP-Mod to write the driver (Root Patch) and for normal booting. Enabling x86legacy will cause a crash upon reboot, entering recovery mode.

2. Relax System Sandbox and Signing: amfi=0x80 has been added to boot-args.

• Reason:* Required for running unsigned network card and sound card patch drivers.

3. Bypass Upgrade and Hardware Detection Restrictions: RestrictEvents.kext is used, and the boot parameter revpatch=sb is configured.

• Reason: To fake a secure boot when SecureBootModel is disabled, allowing the system to receive official minor version incremental updates (OTA) push notifications.

🚀 Installation and Configuration Guide

Step 1: Preparing EFI and Generating the Model Code

1. Copy the entire EFI folder of this project to the EFI partition of your boot disk.

2. Use GenSMBIOS or OCAuxiliaryTools to generate the model code (MLB, SystemSerialNumber, SystemUUID) suitable for iMac20,2 (or Macmini8,1).

3. Open config.plist with a text editor or configuration tool, and fill in the corresponding locations under PlatformInfo -> Generic.

Step 2: Install macOS Tahoe 26.5.1

1. Follow the standard Hackintosh installation steps to install the system via USB boot disk.

2. Upon first entering the system, you will find that there is no sound and you cannot directly connect to WiFi. This is normal; please continue to the next step.

Step 3: Run OCLP-Mod to Restore Sound Card and Bluetooth Drivers (Crucial)

To restore the AppleHDA removed by Apple and make the sound card work properly:

1. Download and open the OCLP-Mod (OpenCore Legacy Patcher Mod) software.

2. Click the Post-Install Root Patch button.

3. Click Start Root Patching and enter your login password. The software will automatically restore the system-level drivers for your sound card and other peripherals.

4. Restart your computer. Upon entering the OpenCore boot menu, a Reset NVRAM must be performed once (to load new kernel security variables), after which the system will boot normally.

5. Now open System Settings -> Sound, and the sound card should be working perfectly!

Step 4: Connecting to WiFi using HeliPort

Since itlwm.kext emulates the wireless network card as an Ethernet interface, a client connection is required:

1. Download the latest version of the HeliPort client (DMG format).

2. Drag HeliPort.app into the system's Applications folder and open it.

3. You will see a WiFi icon in the upper right corner of the screen. Click it, select your WiFi network, and enter the password to connect.

4. It is recommended to check "Launch at Login" in the HeliPort menu to enable automatic connection at boot.

⚙️ Personalized Tuning (Optional)

1. Correct CPU Display in About This Machine

The current configuration includes the parameters revcpu=1 and revcpuname=Intel\Core\i7-8559U.

• This ensures the About This Machine interface correctly identifies your processor as Intel Core i7-8559U (instead of "Unknown"). You can modify the value of revcpuname in boot-args according to your actual CPU model.

2. Remove Verbose Mode (Clean Boot)

Currently, for troubleshooting purposes, the -v parameter (code-based boot animation) is enabled by default. If you want to enjoy the white Apple logo boot screen:

• Edit config.plist and remove -v from boot-args.
