Kext Description
Lilu.kext Patch many processes, required for AppleALC, WhateverGreen, VirtualSMC and many other kexts.
SMCProcessor.kext Used for monitoring CPU temperature, doesn't work on AMD CPU based systems.
SMCSuperIO.kext Used for monitoring fan speed, doesn't work on AMD CPU based systems.
VirtualSMC.kext Emulates the SMC chip found on real macs, without this macOS will not boot.
Alternative is FakeSMC which can have better or worse support, most commonly used on legacy hardware.
WhateverGreen.kext Used for graphics patching, DRM fixes, board ID checks, framebuffer fixes, etc; all GPUs benefit from this kext.

Other Kexts (not included)

Kexts for support Audio, Wifi, Ethernets and other devices.

Audio

Kext Description
AppleALC.kext Used for AppleHDA patching, allowing support for the majority of on-board sound controllers.
AMD 15h/16h may have issues with this and Ryzen/Threadripper systems rarely have mic support.
VoodooHDA.kext Audio for FX systems and front panel Mic+Audio support for Ryzen system, do not mix with AppleALC.
Audio quality is noticeably worse than AppleALC on Zen CPUs.

Ethernet

Kext Description
IntelMausi.kext Intel's 82578, 82579, I217, I218 and I219 NICs are officially supported.
IntelMausiEthernet.kext Alternative for some I219 NICs. Use it if the kext above doesn't work.
IntelMausiEthernet.kext Some alternative for some I219 NICs. Use it if the kext above doesn't work.
AtherosE2200Ethernet.kext Required for Atheros and Killer NICs.
Note: Atheros Killer E2500 models are actually Realtek based, for these systems please use RealtekRTL8111 instead.
RealtekRTL8100.kext Required for Realtek FE Familly Controller - 10/100 Mbps. Common on older hardware.
RealtekRTL8111.kext Required for Realtek Gigabit Ethernet. Realtek GbE Familly Controller
Sometimes the latest version of the kext might not work properly with your Ethernet. If you see this issue, try older versions.
LucyRTL8125Ethernet.kext Required for Realtek 2.5Gb Ethernet.
SmallTreeIntel82576.kext Required for I211 NICs, based off of the SmallTree kext but patched to support I211.
Required for most AMD boards running Intel NICs.
AppleIGB.kext Required for I211 NICs running on macOS Monterey and above. Might have instability issues on some NICs, recommended to stay on Big Sur and use SmallTree. Requires macOS 12 and above.
AppleIGC.kext Required for I226 NICs running on macOS Monterey and above. Might have instability issues on some NICs.
AppleIntelI210Ethernet.kext Required for Intel i225-V in macOS 12 (Monterey) and above.

WiFi and Bluetooth

Kext Description
AirportItlwm Adds support for a large variety of INTEL WIRELESS cards and works natively in recovery thanks to IO80211Family integration.
IntelBluetoothFirmware Adds Bluetooth support to macOS when paired with an Intel wireless card.
AirportBrcmFixup Used for patching non-Apple/non-Fenvi Broadcom cards, will not work on Intel, Killer, Realtek, etc.
For Big Sur see Big Sur Known Issues for extra steps regarding AirPortBrcm4360 drivers.
BrcmPatchRAM Used for uploading firmware on Broadcom Bluetooth chipset, required for all non-Apple/non-Fenvi Airport cards.

USB

Kext Description
USBInjectAll Used for injecting Intel USB controllers on systems without defined USB ports in ACPI.
All Intel chipset series.
Requires OS X 10.11 or newer.
XHCI-unsupported Needed for non-native USB controllers.
Common chipsets needing this: H370, B360, H310, Z390(Not needed on Mojave and newer), X79, X99, AsRock boards(On Intel motherboards specifically, B460/Z490+ boards do not need it however).

Others

Kext Description
NVMeFix Used for fixing power management and initialization on non-Apple NVMe.
SATA-Unsupported Adds support for a large variety of SATA controllers, mainly relevant for laptops which have issues seeing the SATA drive in macOS.
We recommend testing without this first.
RestrictEvents Better experience with unsupported processors like AMD, Disable MacPro7,1 memory warnings and provide upgrade to macOS Monterey via Software Updates when available.
CpuTscSync It is a Lilu plugin, combining functionality of VoodooTSCSync and disabling xcpm_urgency if TSC is not in sync. It should solve some kernel panics after wake.
SMDRadeonGPU Used for monitoring GPU temperature on AMD GPU systems. Requires RadeonSensor from the same repository. Requires macOS 11 or newer.
FeatureUnlock Add Sidecar, NightShift, AirPlay, Universal Control and Continuity Camera support.

ACPI Tables

These files are MUST be included in your EFI's ACPI directory. We recommend that you use the MANUAL method, but for a first test you can use the prebuild versions.

Table Description
SSDT-PLUG-ALT Manual | Prebuilt | Details
SSDT-EC-USBX Manual | Prebuilt | Details
SSDT-AWAC Manual | Prebuilt | Details
SSDT-RHUB Manual | Prebuilt | Details

Dumping your DSDT in Windows Environment

Download iASL Compiler ACPI Tools

Open the CMD in the directory where the ACPI Tools was extracted. (Command Prompt) in Administrator Mode:

path/to/acpidump.exe -b -n DSDT -z
move dsdt.dat DSDT.aml

Decompile DSDT.aml:

path/to/iasl.exe path/to/DSDT.aml

File DSDT.dsl will generated. Use this for generate YOUR ACPI Patches.

Compile DSDT.dsl:

path/to/iasl.exe path/to/DSDT.dsl

File APCPI_FILE_PATCHED.aml will generated.

Attention

Update config.plist in PlatformInfo > Generic with YOUR informations.

1. MLB (Board Serial)
2. ROM (Mac Address)
3. SystemSerialNumber (Serial)
4. SystemUUID (SmUUID)

Please use genSMBIOS for generate values for above itens.
Please use ProperTree for configure/edit your config.plist.

Special notes [DeviceProperties > Add]

  • PLEASE EDIT/ADD DEVICE FOR ETHERNET i225 (You can identify with Hackintool on PCIe tab).
    • If your board didn't ship with the Intel I225 NIC, there's no reason to add this entry.
    • If you get a kernel panic on the AppleIntelI210Ethernet kext, your Ethernet's path is likely PciRoot(0x0)/Pci(0x1C,0x4)/Pci(0x0,0x0).
    • Please ENABLE Patch for i225 on Kernel > Patch.
    • for macOS Monterey 12.2.1 and below, please add dk.e1000=0 in boot-args.
    • for macOS Monterey 12.3 or newer, please add e1000=0 in boot-args.
    • for macOS Ventura, please add e1000=0 in boot-args and add Kext AppleIntelI210Ethernet.kext

GPU-Specific boot-args

Parameter Description
agdpmod=pikera Used for disabling board ID checks on Navi GPUs(RX 5000 series & RX 6000 series), without this you'll get a black screen.
Don't use if you don't have Navi (ie. Polaris and Vega cards shouldn't use this).

Ethernet (Intel i225) boot-args

Parameter Description
dk.e1000=0 Disables com.apple.DriverKit-AppleEthernetE1000 (Apple's DEXT driver) from matching to the Intel I225-V Ethernet controller found on higher end Comet Lake boards, causing Apple's I225 kext driver to load instead.
This boot argument is optional on most boards as they are compatible with the DEXT driver. However, it is required on Gigabyte and several other boards, which can only use the kext driver, as the DEXT driver causes hangs.
You don't need this if your board didn't ship with the I225-V NIC.
e1000=0 for macOS 12.3.1 or newer
Disables com.apple.DriverKit-AppleEthernetE1000 (Apple's DEXT driver) from matching to the Intel I225-V Ethernet controller found on higher end Comet Lake boards, causing Apple's I225 kext driver to load instead.
