Intel NUC Model NUC8i7BEH

This repository contains personal work and files, developed and maintained for a successful use with OpenCore EFI bootloader on this specific Intel NUC model. There are no ready, pre-packaged EFI solutions provided; instead, the needed configuration and ACPI files are published for those interested in studying the code, while creating their own bootloader configurations.

${\textsf{\color{red}The project resumes after repairing a hardware fault affecting all USB ports of the NUC motherboard.}}$

Required BIOS Settings

For the essential but required BIOS settings, as well as previous firmware releases, see BIOS folder.

OpenCore Picker Keyboard Shortcuts

When the Timeout key is set and OpenCore Picker displays the available boot drives:

• Press Space Bar to access the hidden Auxiliary tools e.g. UEFI Shell, NVRAM Cleanup, Verify MSR Lock.
• Press Tab to move selection to the newly available Reboot and Shutdown icons (since OpenCore 0.6.8).

Alternatively, if ShowPicker is disabled or Timeout set to 0, keep pressing Escape or Zero or Option keys to access Picker just before OpenCore kicks-in and starts booting.

Active Configuration

• No CPU ID faking required, power management is native; MSR 0xE2 remains locked; ⚠️
• External USB 3.0 ports work as expected; using generated USBPorts.kext;
• Internal USB 2.0 headers not used; they are disabled in BIOS;
• External USB-C port works for display purposes; special USB-C to miniDP cable used;
• Intel graphics acceleration works as 0x3EA50004 with WhateverGreen;
• Analogue audio output works as layout ID 0x03 with AppleALC;
• Digital audio output works with FakePCIID.kext and the HDMI Audio extension;
• Embedded Intel LAN interface works with IntelMausi;
• Embedded Intel WLAN module works with OpenIntelWireless;
• Embedded Intel BTLE module detected with IntelBluetoothFirmware;
• CPU fan readings work with ec-device as Intel_EC_V8 with VirtualSMC;
• Integrated Realtek SD card reader now gets support with RealtekCardReader;
• Power Management is present and active as X86PlatformPlugin is attached to PR00 in IORegistry;
• Sleep/Wake both work without issues; see "Power" section in Hackintool;
• Both NVMe and SSD SATA interfaces work with no effort nor kext needed.

For the complete list of all detected PCI hardware components and their respective addresses via lspci -nn command (in Ubuntu, loaded via USB) see here. This list was created with all devices enabled in BIOS and is used as a device "map" so that PCI IDs can be detected before tweaking the hardware (and BIOS) to run macOS.

USB Port Mapping on NUC Chassis

USB 2.0 Port Name	USB 3.0 Port Name	Hardware Location	Controller
HS01	SS01	Front RIGHT socket	Primary XHCI
HS02	SS02	Front LEFT socket	Primary XHCI
HS03	SS03	Rear BOTTOM socket	Primary XHCI
HS04	SS04	Rear TOP socket	Primary XHCI
HS10	N/A	Internal BTLE port	Primary XHCI
HS01	SS01	Rear USB-C socket	Secondary XHCI

The above active and working USB ports are listed in Hackintool while the two internal (USB 2.0) headers and Consumer IR are all disabled in BIOS and all unused or non-referenced USB ports are removed. In any other situation, ports such as HS05, HS06, HS07, HS08, HS09, USR1, USR2, SS05 and SS06 may be listed. All ports above are defined in USBPorts.kext according to their electrical connector.

CPU Fan Reading Support

Support for the NUC's embedded chipset ITE IT8987E-VG has been added in VirtualSMC (and more specifically SMCSuperIO.kext) since version 1.2.2 thanks to its developers. This is achieved by injecting the needed property <key>ec-device</key> and the correct identifier that corresponds to the NUC's model/generation own LPC Controller device (see here). For this NUC, the value is <string>Intel_EC_V8</string> thus enabling CPU fan readings in any monitoring tool.

Wireless Connectivity

The embedded 802.11ac wireless 9560 chipset [8086:9df0] has been working without issues with itlwm since Mojave. The controller can be enabled in BIOS, and for aesthetic reasons, can be renamed from Device (CNVW) to (WLAN) via OpenCore patching. As for the embedded BTLE module, Intel reports it being a Bluetooth 5.1 device, which works in most cases with IntelBluetoothFirmware since Mojave, too. Both drivers can be loaded through OpenCore.

CPU Power Management

With the injection of SSDT-PLUG.aml via OpenCore, we can verify that Power Management is present and active as X86PlatformPlugin is attached to the first CPU core PR00 per the Dortania Guide.

Changes Brought About by macOS 12 and later

MacOS 12.x Monterey has brought an important change in OpenCore configuration for BTLE, namely the required removal of IntelBluetoothInjector.kext and its replacement by BlueToolFixup.kext found inside BrcmPatchRAM package. The main IntelBluetoothFirmware.kext remains active and must still be loaded, as done previously.

⚠️ From version 2.2.0 of IntelBluetoothFirmware onwards, there is a new kext IntelBTPatcher.kext included that the developers recommend loading as it fixes a bug in Apple's Monterey re-written Bluetooth stack. For more details read here.

There is also a distinct version of AirportItlwm.kext compiled for Monterey only that has to be installed, replacing the Big Sur version of the kext without any OpenCore configuration changes, however.
