🔧 OpenCore config.plist Key Section Overview

This section provides an explanation of the most commonly used settings in a Hackintosh config.plist file, useful for understanding how OpenCore enables macOS to run on non-Apple hardware.

🖥️ PlatformInfo > Generic

Key Description
SystemProductName Defines the Mac model to spoof (e.g., iMac20,2, MacPro7,1, etc.). This determines compatibility with macOS updates and hardware acceleration.
SystemSerialNumber A unique serial number for the system. Should not match any real Mac to avoid iCloud/iMessage issues.
MLB (Main Logic Board) Logic board serial number. Required for Apple ID services like iMessage and FaceTime. Must match the spoofed SMBIOS model.
ROM Typically the MAC address of the system’s primary network adapter (Ethernet). Used as part of Apple’s service validation.
SystemUUID A Universally Unique Identifier for the system. Used by services such as iCloud, Handoff, and Continuity.

🧠 NVRAM > boot-args

The boot-args field passes arguments to the macOS kernel at startup. These are used for enabling specific functionality, debugging, and patching:

Common Boot Args Description
agdpmod=pikera Enables AMD GPU support by patching AppleGraphicsDevicePolicy. Required for most Navi (RX 5000/6000) cards.
alcid=xx Enables onboard audio through AppleALC, where xx is your layout ID (e.g., alcid=11).
-lilubetaall Allows Lilu to load in macOS beta versions or on newer OS builds.
-wegbeta Enables beta support in WhateverGreen. Useful with newer GPUs or experimental macOS versions.
-v Verbose boot (shows text during boot instead of the Apple logo).
keepsyms=1 debug=0x100 Debug options useful during troubleshooting and kernel panics.
-vsmcbeta, -revbeta Enable beta support for VirtualSMC and RestrictEvents kexts, respectively. Only needed when using beta versions of these kexts.

🧩 Kernel > Add (Kexts)

These kernel extensions (kexts) are required to emulate Apple hardware functionality or enable third-party components:

Kext File Description Required? Notes
Lilu.kext Core patching engine for other kexts like WEG and AppleALC ✅ Yes Always required for modern macOS builds
WhateverGreen.kext Graphics patching for AMD, Intel, and legacy NVIDIA GPUs ✅ Yes Required for RX 6800 XT (use agdpmod=pikera in boot-args)
AppleALC.kext Enables audio via layout injection (e.g., Realtek ALC1220-VB) ✅ Yes Use boot-arg alcid=11 for Gigabyte Z390 onboard audio
VirtualSMC.kext Emulates Apple’s SMC for temperature, fans, power management ✅ Yes Core component – replaces FakeSMC
SMCProcessor.kext Adds CPU temperature sensors (used with VirtualSMC) ⚠️ Optional Only required for monitoring tools like iStat Menus or HWMonitor
SMCSuperIO.kext Adds motherboard fan/voltage sensors ⚠️ Optional Same as above – enables full hardware monitoring
IntelMausi.kext Intel Ethernet driver (i219-V on Z390) ✅ Yes Enables native Ethernet without additional config
NVMeFix.kext Optimizes NVMe SSD behavior and power management ✅ Yes Recommended for all NVMe drives (e.g., WD SN850X)
RestrictEvents.kext Prevents crashes and issues on unsupported CPUs in macOS 14+ ✅ Yes Required for macOS Sonoma and Sequoia
AirportItlwm.kext Intel Wi-Fi support (for CNVi cards) ✅ Yes Use if you rely on built-in Intel Wi-Fi instead of Fenvi T919
BrcmPatchRAM3.kext Enables Broadcom Bluetooth stack ✅ Yes Required for Fenvi T919 or any Broadcom BT module
BrcmFirmwareData.kext Loads Bluetooth firmware for Broadcom adapters ✅ Yes Works in tandem with PatchRAM
BrcmBluetoothInjector.kext Injects BT configuration for Broadcom modules ✅ Yes Required for Broadcom BT on macOS ≤14
USBInjectAll.kext Legacy USB injector for all ports ❌ No Only useful during port-mapping; not needed with SSDT-UIAC.aml or USBPorts.kext
USBPorts.kext / USBToolBox.kext Custom USB mapping solution ✅ Yes Use one or the other (not both); alternative to using SSDT-UIAC.aml

⚙️ ACPI > Add (SSDTs)

Custom SSDTs (ACPI tables) improve hardware compatibility and allow macOS to recognize or emulate missing components:

SSDT Filename Description Required? Notes
SSDT-PLUG.aml Enables native CPU power management via Apple XCPM. ✅ Yes Required for proper CPU frequency scaling.
SSDT-EC.aml Emulates a missing Embedded Controller (EC). ✅ Yes Required for booting on most modern motherboards.
SSDT-UIAC.aml Custom USB port mapping to stay under the 15-port macOS limit. ✅ Yes Should be used instead of USBInjectAll long-term.
SSDT-DTPG.aml Enables patching ACPI methods (_STA/_INI) used by other SSDTs. ✅ Yes Often a dependency for UIAC or Thunderbolt SSDTs.
SSDT-TB3.aml Enables Thunderbolt 3 hotplug and stability. ⚠️ Optional Required if using Thunderbolt ports.
SSDT-DMAR.aml Patches or emulates VT-d ACPI table. ⚠️ Optional Only needed if VT-d is enabled.
SSDT-DMAC.aml Adds DMA controller definition. ⚠️ Optional Avoids ACPI warnings; safe to include.
SSDT-NVRAM.aml Emulates NVRAM if missing in BIOS. ❓ Depends Only for systems without native NVRAM support.
SSDT-USBW.aml Enables USB wake from sleep. ⚠️ Optional Only needed for wake-on-keyboard/mouse.

💡 Notes

  • ✅ = Required for most setups
  • ⚠️ = Only needed in specific situations
  • ❓ = Depends on system firmware/hardware

💡 Notes

  • If your system has trouble booting, try toggling CSM Support.
  • Above 4G Decoding is critical for users with AMD GPUs (like RX 6800 XT).
  • VT-d must be enabled for AppleVTD in macOS 12.3 and later.
  • Always save BIOS settings to a profile for quick recovery in case of resets.

Sonoma and Ventura on OpenCore

🍇 Sonoma and Ventura with OpenCore are working very well. OpenCore EFI files support both Ventura and Sonoma; only difference is OC version and the use of AirPort Itlwm for Intel WiFi.

Sequoia and Sonoma on OpenCore

🌲 Sequoia on Opencore is working fine also with a few things to keep in mind: I'm using Heliport+Itlwm, and when installing it needs the HDMI port instead of the DisplayPort. So far, Sonoma works with the same EFI, so you can dualboot without any trouble.

Tahoe on OpenCore

🏔️ Working on it...

20-6-2025 Progress has been made:

alt test

🧪 Installing macOS Tahoe Developer Beta 1 on a Z390 Designare Hackintosh (i7-9700K)

🚠 Work in Progress Please note: macOS 26 “Tahoe” is still in early developer beta stage. There are multiple unresolved bugs both in Apple’s system components and third-party kexts. Expect instability, incomplete hardware support, and changes with every beta. Use this only on non-critical systems and with a separate SSD.

✅ Requirements

  • A working Hackintosh system (e.g. running macOS Sequoia or earlier)

  • A separate SSD (do not install over your main macOS installation)

  • OCAuxiliaryTools installed on your working system

  • Two provided EFI folders:

    • 20-6-2025 EFI for Installation of Tahoe.zip
    • 20-6-2025 EFI for Tahoe SSD After Install.zip

🛠️ Installation Steps

0. Create a bootable macOS Tahoe USB stick

Follow the instructions here: 🔗 https://github.com/joostiphone/MacOS-USB-Installer

1. Extract 20-6-2025 EFI for Installation of Tahoe.zip

This EFI is specifically prepared to boot the macOS Tahoe installer.

2. Copy this EFI folder to your USB stick

  • Mount the EFI partition of the USB using OCAuxiliaryTools (⌘ + M in OCAT)
  • Replace any existing EFI folder (if there is any) with the extracted one

3. Boot the USB and install macOS Tahoe

  • Boot your Hackintosh using the USB stick (use BIOS boot menu: F12)
  • Select “Install macOS” from OpenCore
  • Be sure to install onto a separate SSD — this ensures your working system remains untouched

4. If installation gets stuck (common in Dev Beta 1):

  • Reboot back into your current macOS installation (e.g. Sequoia) by pressing F12 and choosing Sequoia
  • Mount the EFI partition of the SSD where you just installed Tahoe
  • Use OCAuxiliaryTools to replace that EFI (if any) with the one from: 20-6-2025 EFI for Tahoe SSD After Install.zip

5. Reboot and boot from the macOS Tahoe SSD

  • Use the BIOS (F12) to select the SSD that now holds macOS Tahoe
  • Proceed with the remaining installation steps

6. Complete the installation

macOS should now continue and finalize the setup process. Be patient — it may reboot several times.

7. You’re in!

If all goes well, you’ll land on the macOS Tahoe desktop.

🗭 Notes and Known Issues

  • FileVault seems to turn on all of a sudden in macOS Tahoe Dev1, so make sure that you enable automatic login in macOS Settings
  • Expect bugs and missing features — this is developer-only software

⚠️ Precaution

Serial number:

You need to make your own serial number, so that your iCloud etc. will work without using someone else his serial number. In OC GEN-X or in OpenCore Configurator you can generate a new one if you don't have one yet, or if you need a new one.

  42. 10-7-2023: Updated to OpenCore v0.9.4 dev. This EFI includes the AirPortItlwm (D02) WiFi driver for Intel based WiFi chips. This is eventually required for WiFi on macOS Sonoma. This EFI is setup as such as a combination with Intel WiFi (AirPortItlwm) and Fenvi Bluetooth. For more information, I'm refering to this topic: https://forum.amd-osx.com/threads/testing-intel-wifi-itlwm-driver-for-sonoma.4557/page-2
  43. 6-8-2023: Updated to OpenCore v0.9.4 dev, without AirPortItlm. I will upload a separate Sonoma version later on to keep this as vanilla as possible.
  44. 11-8-2023: Updated to OpenCore v0.9.4 final. Ventura will use Broadcom (Fenvi) and Sonoma will use AirPort Itlwm Preview 05 for Intel WiFi on Sonoma, specifically for Public Beta 5.

Using the following MinKernel and MaxKernel when using OpenCore to do conditional kext configuration when booting a macOS: MinKernel MaxKernel Mojave 18.0.0 18.99.99 Catalina 19.0.0 19.99.99 Big Sur 20.0.0 20.99.99 Monterey 21.0.0 21.99.99 Ventura 22.0.0 22.99.99 Sonoma 23.0.0 23.99.99 Sequoia 24.0.0 24.99.99

macOS Sonoma (macOS 14)

  1. Installing macOS 14.0 beta 1 via the regular Apple channels.
  2. Created a USB. Find the instructions here: https://github.com/joostiphone/MacOS-USB-Installer
  3. Created a first EFI based on the Ventura EFI. For Sonoma, I'm now using the latest OpenCore V0.9.4 dev version, and the latest Kext dev versions.
  4. Updated to Sonoma beta 3
  5. The current EFI is using AirPortItlwm (d02). OpenIntelWireless/itlwm#883 . This means that the Intel WiFi on the Z390 MoBo is being used, instead of the Fenvi (broadcom) WiFi, since macOS Sonoma doesn't support Broadcom chips anymore; which forces us to use the Intel WiFi and AirPortItlwm. The Bluetooth on the Fenvi is still being used.
  6. Updated to Sonoma second version of beta 3
  7. Updated to Sonoma Public Beta 3 with final OpenCore v0.9.4 and final kexts. This is using AirPort Itlwm Preview 05 for Intel WiFi on Sonoma, specifically for Public Beta 5.
  8. Updated to Sonoma RC2 (which will most probably become the Customer version) with final OpenCore v0.9.5 and final kexts. This is using AirPort Itlwm Preview 05 for Intel WiFi on Sonoma, specifically for Public Beta 5 and later.
  9. Updated to Sonoma 14.1 with OpenCore v0.9.5.
  10. Updated to Sonoma 14.2 with OpenCore v0.9.7.
  11. Updated to Sonoma 14.5 with OpenCore v1.0.0.

macOS Sequoia (macOS 15)

Notes: Sequoia works, the only thing that isn't working is WiFi (AirportItlwm) and/or Fenvi (Broadcom).

Ethernet works just fine. During the Sequoia installation, to avoid a black screen, I needed to use my HDMI port instead of the DisplayPort. After the installation the DisplayPort worked again. Extra settings compared to Sonoma:

Updated all kexts to their beta versions and added RestrictEvents.kext (don't forget to add -revbeta to boot arguments) Updated OpenCore to 101 dev version Using the following boot arguments: keepsyms=1 debug=0x100 agdpmod=pikera alcid=11 -v -revbeta -lilubetaall -wegbeta -vsmcbeta

Optionally Overclocking to 5Ghz:

Some basic settings, but you can still look at the attached BIOS screenshots for further details:

  • CPU Base Clock: 100Mhz
  • Extreme Memory Profile (XMP): Profile 1
  • CPU Vcore: 1.370V (instead of standard 1.200V). This is pretty high and cause degration of your CPU, just be aware...
  • Active Turbo Ratios: Enabled, and set every core on 50 (50 times 100Mhz CPU Base Clock = 5000Mhz).
  • C-States Control: Enable (disable all options there)
