How to Create OpenCore Config.plist file for booting macOS on Intel Desktops

An EliteMacx86 Exclusive Guide - This guide covers creation of config.plist for booting macOS on Intel Desktops for OpenCore as a bootloader.

Overview

The config.plist is a system configuration file for the Hackintosh and allows to boot macOS. Without a config.plist, no machine can boot into macOS.

A basic config.plist file is bundled with OpenCore. The config.plist which comes with OpenCore, is the default config.plist and is not optimised for all the systems. It can boot into some installation but when talking about the majority, it will fail to boot on most of the newer machines and high end builds.

Also, it's a good idea to create a config.plist for each specific system which will exclude the errors and trouble while installation and you can easily boot into macOS installation. The configuration file is written in XML and can be edited using a text editor. But we don't recommend you to use a text editor as it has a chance of config.plist file corruption. The best way to edit a config.plist is to use some specific tools like Clover Configurator, Xcode, Plist Editor Pro etc..

This guide covers a creation of basic config.plist which will allow to boot most of the systems.

You can add your add-on DSDT or SSDTs here when performing Post-Install.

Delete
This section allows to block the ACPI tables from loading. For a Sandy Bridge system, it's necessary to drop the tables as XCPM is not supported on all Sandy Bridge Systems. A workaround is to drop the tables for installing and create a SSDT for CPU PM during Post-Install.

Table Signature*	OemTableId	TableLength	Comment	All	Enabled	Notes
	437075506d000000	0	Drop CpuPm	YES	YES	This patch drops Cpupm table. Mandatory for all Sandy Bridge Systems.
	4370753049737400	0	Drop Cpu0Ist	YES	YES	This patch drops Cpu0Ist table. Mandatory for all Sandy Bridge Systems.

Note:
If you don't drop the tables, you can have a AppleIntelCPUPowerManagement panic when booting the installer.

Patch
This section is used for device renames such as USB, Graphics and Audio. You can implement the necessary ACPI patches for optimising the ACPI system components with DSDT and SSDT. This section is important when doing Hot-patch.

The required renames for a Sandy Bridge system includes:

DSDT	45484331	45483031	Rename EHC1 to EH01 (USB)*	YES	Renames EHC1 to EH01 for proper USB functioning. This rename is required for fixing USB Ports with EHCI Controller.
DSDT	45484332	45483032	Rename EHC2 to EH02 (USB)*	YES	Renames EHC2 to EH02 for proper USB functioning. This rename is required for fixing USB Ports with EHCI Controller.
DSDT	47465830	49475055	Rename GFX0 to IGPU (Graphics)	YES	Renames GFX0 to IGPU for a better power power management. This rename is required for implementing IGPU Power Management. Only use if you're using IGPU as a Graphics Device. On few motherboards, this rename can lead to still waiting for device error. If you encounter such issue, disable this rename.
DSDT	50454750	47465830	Rename PEGP to GFX0 (Graphics)	YES	Renames PEGP to GFX0 for a better power management. This rename is required for implementing discrete GPU Power Management. Only use if you're using Discrete Graphics Card.
DSDT	415A414C	48444546	Rename AZAL to HDEF (Audio)	YES	Renames HDAS to HDEF for Audio. This rename is required for implementing Audio Function. For Branded Systems, you may need to patch your DSDT. For more information on Audio implementation, read here.

Notes:

The EHC renames must be used in the conjunction to enable the proper USB renaming.
*Requires both renames for full function.
If you're using Discrete Graphics Device, it's advised to disable IGPU for less hassle.

This provides basic filesystem integrity verification and may protect from unintentional filesystem corruption. Secure Requires vault.sig signature file for vault.plist in OC directory. This includes Basic integrity checking but also attempts to build a trusted boot chain.
BootProtect	None Boostrap	Attempt to provide bootloader persistence None Enables usage of Bootstrap.efi in the directory EFI/OC/Bootstrap instead of BOOTx64.efi. This setting is helpful for users using rEFInd to boot or avoid BOOTx64.efi overwrites from Windows. Bootstrap *For this option to work RequestBootVarRouting is required to be enabled.* *Use of Bootstrap option will also enable "OpenCore" instead of UEFI: OS followed by your drive name in Boot Menu.*
DmgLoading	Disabled Signed Any	Define Disk Image (DMG) loading policy used for macOS Recovery. Disabled Disables loading of DMG images. Disabled policy will still let macOS Recovery to load in most cases as there usually are boot.efi files compatible with Apple Secure Boot. Manually downloaded DMG images stored in com.apple.recovery.boot directories will not load. Signed Enables only Apple-signed DMG images will load. Due to Apple Secure Boot design Signed policy will let any Apple-signed macOS Recovery to load regardless of Apple Secure Boot state, which may not always be desired. *It's recommended to set this option to "Signed" to avoid issues.* Any Enables any DMG images will mount as normal filesystems. Any policy is strongly not recommended and will cause a boot failure when Apple Secure Boot is activated.
SecureBootModel	Default Disabled	Defines Apple Secure Boot hardware model. Sets Apple Secure Boot hardware model and policy. Specifying this value defines which operating systems will be bootable. Operating systems shipped before the specified model was released will not boot. Default Enables Default Secure Boot.

This provides basic filesystem integrity verification and may protect from unintentional filesystem corruption. Secure Requires vault.sig signature file for vault.plist in OC directory. This includes Basic integrity checking but also attempts to build a trusted boot chain.
BootProtect	None Boostrap	Attempt to provide bootloader persistence None Enables usage of Bootstrap.efi in the directory EFI/OC/Bootstrap instead of BOOTx64.efi. This setting is helpful for users using rEFInd to boot or avoid BOOTx64.efi overwrites from Windows. Bootstrap *For this option to work RequestBootVarRouting is required to be enabled.* *Use of Bootstrap option will also enable "OpenCore" instead of UEFI: OS followed by your drive name in Boot Menu.*
DmgLoading	Disabled Signed Any	Define Disk Image (DMG) loading policy used for macOS Recovery. Disabled Disables loading of DMG images. Disabled policy will still let macOS Recovery to load in most cases as there usually are boot.efi files compatible with Apple Secure Boot. Manually downloaded DMG images stored in com.apple.recovery.boot directories will not load. Signed Enables only Apple-signed DMG images will load. Due to Apple Secure Boot design Signed policy will let any Apple-signed macOS Recovery to load regardless of Apple Secure Boot state, which may not always be desired. *It's recommended to set this option to "Signed" to avoid issues.* Any Enables any DMG images will mount as normal filesystems. Any policy is strongly not recommended and will cause a boot failure when Apple Secure Boot is activated.
SecureBootModel	Default Disabled	Defines Apple Secure Boot hardware model. Sets Apple Secure Boot hardware model and policy. Specifying this value defines which operating systems will be bootable. Operating systems shipped before the specified model was released will not boot. Default Enables Default Secure Boot.
