This repository contains personal work and files, developed and maintained for a successful use with Clover 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.

For the essential but required BIOS settings, as well as previous firmware releases, see BIOS folder.
- No CPU ID faking required, power management is native; MSR
0xE2remains 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;
- Intel graphics acceleration works as
0x0D220003with WhateverGreen; - Analogue audio output works as layout ID
0x01with AppleALC; - Digital audio output works right out-of-the-box (using a MiniDP to MiniDP cable);
- Embedded Intel LAN interface works with IntelMausi;
- Replaced WLAN module works with AirportBrcmFixup;
- Replaced BTLE module works with BrcmPatchRAM;
- CPU fan readings work natively with VirtualSMC;
- Sleep/Wake both work without issues; see "Power" section in Hackintool;
- Both mSATA 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.
The AAPL,ig-platform-id property set to 0x0D220003 is used for WhateverGreen to successfully enable acceleration on this graphics device [8086:0a26]. This ID represents the following properties and connectors:
| Properties | Current Value(s) |
|---|---|
| Platform ID | 0x0D220003 i.e. 0300220D → AwAiDQ== |
| Device ID | 0x0A260000 i.e. No Change |
| Mobile | No |
| Stolen Memory | 32 MB |
| Framebuffer Memory | 19 MB |
| Video Memory (VRAM) | 1536 MB |
| Total Stolen Memory | 52 MB |
| Total Cursor Memory | 1 MB |
| Maximum Stolen Memory | 116 MB |
| Maximum Overall Memory | 117 MB |

| Patching Required | No |
WhateverGreen.kext there was a need to change the Platform ID from 0x0A26000D to 0x0D220003 as graphics acceleration exhibited problems:
| Properties | Original Value(s) |
|---|---|
| Platform ID | 0x0A26000D i.e. 0D00260A → DQAmCg== |
| Device ID | 0x0A260000 i.e. No Change |

| USB 2.0 Port Name | USB 3.0 Port Name | Hardware Location | Controller |
|---|---|---|---|
| HP11 to HP18 | N/A | Internal PR11 Hub | EHCI |
| HS01 | SS01 | Front RIGHT socket | XHCI |
| HS02 | SS02 | Front LEFT socket | XHCI |
| HS03 | SS03 | Rear TOP socket | XHCI |
| HS04 | SS04 | Rear BOTTOM socket | XHCI |
| HS07 | N/A | Internal BTLE port | XHCI |
The above active and working USB ports are listed in Hackintool when the two internal (USB 2.0) headers and Consumer IR are all disabled in BIOS and when all unused or non-referenced USB ports are removed. In any other situation, ports such as HS05, HS06, HS08, HS09, HS10, USR1, USR2, SS05 and SS06 may be listed. All ports above are defined in USBPorts.kext according to their electrical connector.
However, one could also disable the EHCI controller for improved stability and compatibility (including sleep) by redirecting all USB connections to the XHCI controller. For this, we must use SSDT-EHCI-OFF.aml as well as the newer version of the compiled USBPorts.kext in Hackintool. This also implies that there is no longer the need to rename the device EHC1 to EH01 in Clover.
Support for the NUC's embedded Nuvoton NCT5577D chipset was already available in VirtualSMC (and more specifically SMCSuperIO.kext).
With Clover option PluginType set to true we can verify that Power Management is present and active as X86PlatformPlugin is attached to the first CPU core CPU0 per the Dortania Guide.
