Kexts included (Required)

Kext	Description
AMDRyzenCPUPowerManagement.kext	For AMD Power Gadget.
SMCAMDProcessor.kext	For AMD Power Gadget.
AppleMCEReporterDisabler.kext	Useful starting with Catalina to disable the AppleMCEReporter kext which will cause kernel panics on AMD CPUs and dual-socket systems.
Lilu.kext	Patch many processes, required for AppleALC, WhateverGreen, VirtualSMC and many other kexts.
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.
AtherosE2200Ethernet.kext	Required for Atheros and Killer NICs. Note: Atheros Killer E2500 models are actually Realtek based, for these systems please use RealtekRTL8111 instead.
RealtekRTL8111.kext	For Realtek's Gigabit Ethernet. Sometimes the latest version of the kext might not work properly with your Ethernet. If you see this issue, try older versions.
LucyRTL8125Ethernet.kext	For Realtek's 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.

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.

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.
AppleMCEReporterDisabler	Useful starting with Catalina to disable the AppleMCEReporter kext which will cause kernel panics on AMD CPUs. Recommended for dual-socket systems (ie. Intel Xeons).

ACPI Tables - AMD

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-EC-USBX	Manual | Prebuilt | Details
SSDT-CPUR	Prebuilt Only for B550 and A520

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.

Compatible SMBIOS

SMBIOS	Description
iMacPro1,1	AMD RX Polaris and newer.
MacPro7,1	AMD RX Polaris and newer. Note that MacPro7,1 is exclusive to macOS 10.15, Catalina and newer.
MacPro6,1	AMD R5/R7/R9 and older.
iMac14,2	Nvidia Kepler and newer. Note: iMac14,2 is only supported to macOS 10.8-10.15, for macOS 11, Big Sur and newer please use MacPro7,1.

Catalina and older versions of macOS

• Please configure MinDate and MinVersion in UEFI > APFS to -1;
• Please configure SecureBootModel in Misc > Security to j137;

* Without above settings, macOS will not be able to boot.

Special notes

• USB port mapping is REQUIRED.
• XhciPortLimit - Needed DISABLE if you use Big Sur 11.3+.
  • Please Mapping USB in macOS Catalina before install Big Sur or Newer for best results.
  • You can use USBMap.command Utility - USBMap.
• SetupVirtualMap in config.plist:
  • B550, A520 and TRx40 boards should DISABLE this;
  • Newer BIOS versions of X570 also require this DISABLE;
  • X470 and B450 with late 2020 BIOS updates also require this DISABLE.
• DevirtualiseMmio - TRx40 users please ENABLE this flag.

Special notes - Opencore 0.7.1+

Find the three algrey - Force cpuid_cores_per_package patches and alter the Replace value only - config.plist.

Changing B8000000 0000/BA000000 0000/BA000000 0090* to B8 <CoreCount> 0000 0000/BA <CoreCount> 0000 0000/BA <CoreCount> 0000 0090* substituting <CoreCount> with the hexadeciamal value matching your physical core count.

Note: The three different values reflect the patch for different versions of macOS. Be sure to change all three if you boot macOS 10.13 to macOS 12

See the table below for the values matching your CPU Core Count.

CoreCount	Hexadecimal
6 Core	06
8 Core	08
12 Core	0C
16 Core	10
32 Core	20

So for example a 6 Core 5600X Replace value would result in these replace values, B8 06 0000 0000/BA 06 0000 0000/BA 06 0000 0090

Note: MacOS Monterey installation requires Misc -> Security -> SecureBootModel to be disabled in the config.
Also TPM needs to be disabled in the BIOS. Both can be enabled after install.

TRX40 Systems

Disabling the mtrr_update_action - fix PAT patch has shown an improvement in GPU performance on some systems that have tested. If you wish to test this it is recommended to do so on a USB with OpenCore to ensure it works first. There may be issues with different motherboard/GPU combos that we aren't aware of. Proceed at your own risk.

General Purpose boot-args

Parameter	Description
npci=0x2000	This disables some PCI debugging related to kIOPCIConfiguratorPFM64, alternative is npci=0x3000 which disables debugging related to gIOPCITunnelledKey in addition. Required for when getting stuck on PCI Start Configuration as there are IRQ conflicts relating to your PCI lanes. Not needed if Above4GDecoding is enabled.
npci=0x3000	Alternative for npci=0x2000.

GPU-Specific boot-args

Parameter	Description
agdpmod=pikera	Used for disabling board ID checks on Navi GPUs(RX 5000 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).
nvda_drv_vrl=1	Used for enabling Nvidia's Web Drivers on Maxwell and Pascal cards in Sierra and High Sierra.

BIOS Settings

Disable

• Fast Boot
• Secure Boot
• Serial/COM Port
• Parallel Port
• Compatibility Support Module (CSM)(Must be off, GPU errors like gIO are common when this option in enabled)

Special note for 3990X users: macOS currently does not support more than 64 threads in the kernel, and so will kernel panic if it sees more. The 3990X CPU has 128 threads total and so requires half of that disabled. We recommend disabling hyper threading in the BIOS for these situations.

Enable

• Above 4G decoding
  • This must be on, if you can't find the option then add npci=0x2000 to boot-args.
  • Do not have both this option and npci in boot-args enabled at the same time.
  • If you are on a Gigabyte/Aorus or an AsRock motherboard, enabling this option may break certain drivers(ie. Ethernet) and/or boot failures on other OSes, if it does happen then disable this option and opt for npci instead.
  • 2020+ BIOS Notes: When enabling Above4G, Resizable BAR Support may become an available on some X570 and newer motherboards. Please ensure this is DISABLED instead of set to Auto.
• EHCI/XHCI Hand-off
• OS type: Windows 8.1/10 UEFI Mode
• SATA Mode: AHCI
