You'll want to start with the sample.plist that OpenCorePkg provides you in the DOCS folder and rename it to config.plist. Next, open up your favourite XML editor like ProperTree and we can get to work.
Users of ProperTree will also get the benefit of running the Snapshot function which will add all the Firmware drivers, kexts and SSDTs into your config.plist(Cmd/Crtl + R and point to your OC folder).
Do note that images will not always be the most up-to-date so please read the text below them, if nothing's mentioned then leave as default.
And read this guide more than once before setting up OpenCore and make sure you have it set up correctly
For us we'll need a couple of SSDTs to bring back functionality that Clover provided:
Allows for native CPU power management, Clover alternative would be under
Acpi -> GenerateOptions -> PluginType. Do note that this SSDT is made for systems where
CPU0, though some ACPI tables have theirs starting at
PR00 so adjust accordingly. Seeing what device has AppleACPICPU connected first in IORegistryExplorer can also give you a hint
This is the 300 series RTC patch, required for most B360, B365, H310, H370, Z390 and some Z370 boards which prevent systems from booting macOS. The alternative is SSDT-RTC0 for when AWAC SSDT is incompatible due to missing the Legacy RTC clock, to check yourself which is needed search for
AWAC and if this shows up then search for
STAS in your DSDT. If nothing returns from the
STAS search then you'll need the RTC0 patch
For those having troubles understanding the SSDTs regarding plugin type and EC can use CorpNewt's SSDTTime to properly set up your SSDT. All other SSDTs can be compiled with MaciASL, don't forget that compiled SSDTs have a .aml extension(Assembled) and will go into the EFI/OC/ACPI folder. You can compile with MaciASL by running File -> Save As -> ACPI Machine Language. And no need to add your DSDT to Opencore as its already inside your firmware.
For a much deeper rundown on ACPI including compiling in Windows and Linux, see the Getting started with ACPI page.
This drops certain ACPI tabes from loading, for us we can ignore this
This section allows us to dynamically modify parts of the ACPI (DSDT, SSDT, etc.) via OpenCore. Most PCs do not ACPI patches, so in the majority of the cases, you need to do nothing here. For those who need DSDT patches for things like XHC controllers, use SSDTs or similar Device Property patching like what's seen with Framebuffer patching.
Name of patch
How many time the patch is applied,
0 will apply to all instances
Self-explanatory, enables or disables the patch
The original name in ACPI
The new name in ACPI, the length must match original
Quirk: Settings for ACPI.
Enable reboot and shutdown on legacy hardware, not recommended unless needed
Cleanup ACPI header fields, only relevant for macOS High Sierra 10.13
Attempt to heuristically relocate ACPI memory regions, not needed unless custom DSDT is used.
Needed for hardware that fails to maintain hardware signature across the reboots and cause issues with waking from hibernation
Workaround for OEM Windows logo not drawing on systems with BGRT tables.
This section is dedicated to quirks relating to boot.efi patching with FwRuntimeServices, the replacement for AptioMemoryFix.efi
This section is allowing devices to be passthrough to macOS that are generally ignored, most users can ignore this section.
Fixes UEFI runtime services like date, time, NVRAM, power control, etc
Reduces Stolen Memory Footprint, expands options for
Disables the use of
-s, this is closer to the behaviour of T2 based machines
Needed for systems with non-functioning NVRAM, thanks to SSDT-PMC we no longer need this option
Reuse original hibernate memory map, only needed for certain legacy hardware
Allows for slide values to be used in Safemode
Removes write protection from CR0 register during their execution
Ensures ExitBootServices calls succeeds even when MemoryMap has changed, don't use unless necessary
Needed for fixing artefacts and sleep-wake issues, AvoidRuntimeDefrag resolves this already so avoid this quirk unless necessary
If there's a conflicting slide value, this option forces macOS to use a pseudo-random value. Needed for those receiving
Only N/256 slide values are usable! debug message
Fixes SetVirtualAddresses calls to virtual addresses
Needed for systems with large memory maps that don't fit, don't use unless necessary
Add: Sets device properties from a map.
This section is set up via Headkaze's Intel Framebuffer Patching Guide and applies only one actual property to begin, which is the ig-platform-id. The way we get the proper value for this is to look at the ig-platform-id we intend to use, then swap the pairs of hex bytes.
If we think of our ig-plat as
0xAABBCCDD, our swapped version would look like
The two ig-platform-id's we use are as follows:
0x3E9B0007 - this is used when the iGPU is used to drive a display
07009B3E when hex-swapped
0x3E920003 - this is used when the iGPU is only used for computing tasks and doesn't drive a display
0300923E when hex-swapped
Worth noting that for 10.12 -> 10.13.5, you would need to fake the iGPU to the same values in the Kaby Lake guide, as this was before native Coffee Lake iGPU showed up.
We also add 2 more properties, framebuffer-patch-enable and framebuffer-stolenmem. The first enables patching via WhateverGreen.kext, and the second sets the min stolen memory to 19MB. This is usually unnecessary, as this can be configured in BIOS.
I added another section as well that shows a fake
device-id for the i3-8100's UHD 630. This has a different device id than the UHD 630 found on the 8700k, for instance, (
For this - we follow a similar procedure as our above ig-platform-id hex swapping - but this time, we only work with the first two pairs of hex bytes. If we think of our device id as 0xAABB0000, our swapped version would look like 0xBBAA0000. We don't do anything with the last 2 pairs of hex bytes.
The device-id fake is set up like so:
0x3e920000 - this is the device id for the UHD 630 found on an 8700k
923e0000 when hex swapped
Note: FakeID is only required for High Sierra, Mojave doesn't require this
For users with black screen issues after verbose on B360, B365, H310, H370, Z390, please see the BusID iGPU patching page
Applies AppleALC audio injection, you'll need to do your own research on which codec your motherboard has and match it with AppleALC's layout. AppleALC Supported Codecs.
Keep in mind that some motherboards have different device locations, you can find yours by either examining the device tree in IOReg or using gfxutil. Please note that ADR for HDAS/HDEF is 0x001F0003 and Path = PciRoot(0x0)/Pci(0x1f,0x3), PciRoot(0x0)/Pci(0x1b,0x0) is generally for Haswell and earlier. You can find your audio path with the following(Do note, not all audio controllers are called HDEF, sometimes being known as HDAS, AZAL, HDAU and such):
path/to/gfxutil -f HDEF
Do note that
layout-id is a
Data value meaning you will need to convert from
Layout=5 would be interpreted as
Layout=11 would be
<0B000000>. Audio can be left for post-install.
Fun Fact: The reason the byte order is swapped is due to Endianness, specifically Little Endians that modern CPUs use for ordering bytes. The more you know!
Block: Removes device properties from the map, for us we can ignore this
Add: Here's where you specify which kexts to load, order matters here so make sure Lilu.kext is always first! Other higher priority kexts come after Lilu such as VirtualSMC, AppleALC, WhateverGreen, etc. A reminder that ProperTree users can run Cmd/Ctrl+R to add all their kexts in the correct order without manually typing each kext out.
Name of the kext
Self-explanatory, either enables or disables the kext
Path to the actual executable hidden within the kext, you can see what path you kext has by right-clicking and selecting
Show Package Contents. Generally, they'll be
Contents/MacOS/Kext but some have kexts hidden within under
Plugin folder. Do note that Plist only kexts do not need this filled in.
Path to the
info.plist hidden within the kext
Emulate: Needed for spoofing unsupported CPUs like Pentiums and Celerons
CpuidMask: When set to Zero, original CPU bit will be used
<Clover_FCPUID_Extended_to_4_bytes_Swapped_Bytes> | 00 00 00 00 | 00 00 00 00 | 00 00 00 00
0x0306A9 would be
A9 06 03 00 | 00 00 00 00 | 00 00 00 00 | 00 00 00 00
CpuidData: The value for the CPU spoofing
FF FF FF FF | 00 00 00 00 | 00 00 00 00 | 00 00 00 00
FF if needing to swap with a longer value
Block: Blocks kexts from loading. Sometimes needed for disabling Apple's trackpad driver for some laptops.
Patch: Patches both the kernel and kexts (this is where you would add AMD CPU patches).
Only needed when CFG-Lock can't be disabled in BIOS, Clover counterpart would be AppleIntelCPUPM. Please verify you can disable CFG-Lock, most systems won't boot with it on so requiring use of this quirk
Only needed when CFG-Lock can't be disabled in BIOS, Clover counterpart would be KernelPM. Please verify you can disable CFG-Lock, most systems won't boot with it on so requiring use of this quirk
Disables multiple MSR access needed for unsupported CPUs like Pentiums and certain Xeons
Forces maximum multiplier, only recommended to enable on scientific or media calculation machines that are constantly under load. Main Xeons benifit from this
Performs GUID patching for UpdateSMBIOSMode Custom mode. Usually relevant for Dell laptops
Needed to get around VT-D if either unable to disable in BIOS or needed for other operating systems, much better alternative to
dart=0 as SIP can stay on in Catalina
External Icons Patch, for when internal drives are treated as external drives but can also make USB drives internal. For NVMe on Z87 and below you just add built-in property via DeviceProperties.
Increases 32-bit PCI bar size in IOPCIFamily from 1 to 4 GB, enabling Above4GDecoding in the BIOS is a much cleaner and safer approach. Some X99 boards may require this, you'll generally expereince a kernel panic on IOPCIFamily if you need this
Disables kernel panic on AP core lapic interrupt, generally needed for HP systems. Clover equivalent is
Allows for reading kernel panics logs when kernel panics occur
Helps fix kernel panics relating to power changes with Apple drivers in macOS Catalina, most notably with digital audio.
Enables TRIM, not needed for NVMe but AHCI based drives may require this. Please check under system report to see if your drive supports TRIM
This is actually the 15 port limit patch, don't rely on it as it's not a guaranteed solution for fixing USB. Please create a USB map when possible.
The reason being is that UsbInjectAll reimplements builtin macOS functionality without proper current tuning. It is much cleaner to just describe your ports in a single plist-only kext, which will not waste runtime memory and such
Boot: Settings for boot screen (leave as-is unless you know what you're doing)
Best to avoid hibernation with Hackintoshes all together
Hides the EFI partition as a boot option in OC's boot picker
Allows you to use Apple's hotkeys during boot, depending on the firmware you may need to use AppleUsbKbDxe.efi instead of OpenCore's builtin support. Do note that if you can select anything in OC's picker, disabling this option can help. Popular commands:
Cmd+V: Enables verbose
Cmd+Opt+P+R: Cleans NVRAM
Cmd+R: Boots Recovery partition
Cmd+S: Boot in Single-user mode
Option/Alt: Shows boot picker when
ShowPicker set to
NO, an alternative is
This sets how long OpenCore will wait until it automatically boots from the default selection
Shows OpenCore's UI, needed for seeing your available drives or set to NO to follow default option
Uses OpenCore's default GUI, set to NO if you wish to use a different GUI
Debug: Debug has special use cases, leave as-is unless you know what you're doing.
DisableWatchDog: YES (Useful for when OpenCore is stalling on something while booting, can also help for early macOS boot issues)
Shows more debug information, requires debug version of OpenCore
Security: Security is pretty self-explanatory.
Allows for NVRAM reset both in the boot picker and when pressing
CTRL+Index to set default boot device in the picker
Enables Authenticated restart for FileVault2 so password is not required on reboot. Can be concidered a secuirty risk so optional
Shows more debug information, requires debug version of OpenCore
We won't be dealing vaulting so we can ignore
We won't be dealing vaulting so we can ignore as well
0 allows you to see all drives available, please refer to Security section for furthur details
Shows even more debug information, requires debug version of OpenCore
These values are based of those calculated in OpenCore debugging
Tools Used for running OC debugging tools like clearing NVRAM

Add: 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14 (Booter Path, majority can ignore but )
01: Standard resolution(Clover equivalent is
02: HiDPI (generally required for FileVault to function correctly on smaller displays, Clover equivalent is
7C436110-AB2A-4BBB-A880-FE41995C9F82 (System Integrity Protection bitmask)
-v - this enables verbose mode, which shows all the behind-the-scenes text that scrolls by as you're booting instead of the Apple logo and progress bar. It's invaluable to any Hackintosher, as it gives you an inside look at the boot process, and can help you identify issues, problem kexts, etc.
debug=0x100 - this disables macOS's watchdog which helps prevents a reboot on a kernel panic. That way you can (hopefully) glean some useful info and follow the breadcrumbs to get past the issues.
keepsyms=1 - this is a companion setting to debug=0x100 that tells the OS to also print the symbols on a kernel panic. That can give some more helpful insight as to what's causing the panic itself.
shikigva=40 - this flag is specific for Nvidia users. It enables a few Shiki settings that do the following (found here):
8 - AddExecutableWhitelist - ensures that processes in the whitelist are patched.
32 - ReplaceBoardID - replaces board-id used by AppleGVA by a different board-id. Do note that this generally needed for systems running Nvidia GPUs
Note: Some Z390 users may need to calculate a slide value to get around "Couldn't Allocate Runtime" errors. See Fixing KALSR slide values for more info.
csr-active-config: Settings for SIP, generally recommended to manually change this within Recovery partition with
csrutil via the recovery partition
csr-active-config is set to
E7030000 which effectively disables SIP. You can choose a number of other options to enable/disable sections of SIP. Some common ones are as follows:
00000000 - SIP completely enabled
30000000 - Allow unsigned kexts and writing to protected fs locations
E7030000 - SIP completely disabled
Needed for non-Latin keyboards in the format of
lang-COUNTRY:keyboard, recommended keeping blank though you can specify it(Default in Sample config is Russian):
656e2d55533a30 in HEX)
Full list can be found in AppleKeyboardLayouts.txt
Block: Forcibly rewrites NVRAM variables, do note that
Add will not overwrite values already present in NVRAM so values like
boot-args should be left.
Allows for NVRAM to be stored on nvram.plist, needed for systems without native NVRAM
Permits overwriting firmware variables from nvram.plist, only needed for systems without native NVRAM
Used for assigning NVRAM variables, used with LegacyEnable set to YES
Enables writing to flash memory for all added variables.
For setting up the SMBIOS info, we'll use CorpNewt's GenSMBIOS application.
For this Coffee Lake example, I chose the iMac18,1 SMBIOS - this is done intentionally for compatibility's sake. There are two main SMBIOS used for Coffee Lake:
iMac18,1 - this is used for computers utilizing the iGPU for displaying.
iMac18,3 - this is used for computers using a dGPU for displaying, and an iGPU for computing tasks only.
Note: While iMac19,1 and iMac19,2 are a closer match, these SMBIOS are not compatible with versions of macOS older than Mojave and not all fixes are compatible with them(ie: USBInjectAll)
GenSMBIOS would give us output similar to the following:
######################################################## iMac18,1 SMBIOS Info ########################################################Type: iMac18,1Serial: C02XG0FDH7JYBoard Serial: C02839303QXH69FJASmUUID: DBB364D6-44B2-4A02-B922-AB4396F16DA8
Type part gets copied to Generic -> SystemProductName.
Serial part gets copied to Generic -> SystemSerialNumber.
Board Serial part gets copied to Generic -> MLB.
SmUUID part gets copied toto Generic -> SystemUUID.
We set Generic -> ROM to either an Apple ROM (dumped from a real Mac), your NIC MAC address, or any random MAC address (could be just 6 random bytes, for this guide we'll use
Reminder that you want valid serial numbers but those not in use, you want to get a message back like: "Purchase Date not Validated"
Generates PlatformInfo based on Generic section instead of DataHub, NVRAM, and SMBIOS sections
Swaps vendor field for Acidanthera, generally not safe to use Apple as a vendor in most case
Used for when the EFI partition isn't first on the windows drive
Update Data Hub fields
Update NVRAM fields
Updates SMBIOS fields
Replace the tables with newly allocated EfiReservedMemoryType, use Custom on Dell laptops requiring CustomSMBIOSGuid quirk
Forces .efi drivers, change to NO will automatically connect added UEFI drivers. This can make booting slightly faster, but not all drivers connect themselves. E.g. certain file system drivers may not load.
Drivers: Add your .efi drivers here
Input: Related to boot.efi keyboard passthrough used for FileVault and Hotkey support
The delay between each key input when holding a key down, for best results use
The length of time that a key will be registered before resetting, for best results use
Enables OpenCore's built in key support and required for boot picker selection, do not use with AppleUsbKbDxe.efi
Keyboard translation for OpenCore
Used for fixing broken pointer support, commonly used for Z87 Asus boards
Specifies OEM protocol, currently only supports Z87 and Z97 ASUS boards so leave blank
Set architecture timer resolution, Asus Z87 boards use
60000 for the interface. Settings to
0 can also work for some
Protocols: (Most values can be ignored here as they're meant for real Macs/VMs)
Reinstalls Apple SMC I/O, this is the equivlant of VirtualSMC.efi which is only needed for users using FileVault
Replaces Console Control protocol with a builtin version, set to YES otherwise you may see text output during booting instead of nice Apple logo. Required for most APTIO firmware
Fixes UI regarding Filevault, set to YES for better FileVault compatibility
Fixes incorrect cursor size when running FileVault, set to YES for better FileVault compatibility
Some older firmware have broken Unicode collation, fixes UEFI shell compatibility on these systems(generally IvyBridge and older)
Workaround for when te motherboard can't properly access higher memory in UEFI Boot Services. Avoid unless necessary(affected models: GA-Z77P-D3 (rev. 1.1))
Only required for very specific use cases like setting to
5 for ASUS Z87-Pro running FileVault2
Fix for when MSR_FLEX_RATIO (0x194) can't be disabled in the BIOS, required for all pre-skylake based systems
Fix for UI corruption when both text and graphics outputs happen, set to YES with SanitiseClearScreen also set to YES for pure Apple Logo(no verbose screen)
Enables GOP(Graphics output Protcol) which the macOS bootloader requires for console handle, required for seeing once the kernel takes over
Releases USB controller from firmware driver, needed for when your firmware doesn't support EHCI/XHCI Handoff. Clover equivalent is
Request fallback of some Boot prefixed variables from
EFI_GLOBAL_VARIABLE_GUID. Used for fixing boot options.
Redirects AptioMemeoryFix from
OC\_VENDOR\_VARIABLE\_GUID. Needed for when firmware tries to delete boot entries and is recommended to be enabled on all systems for correct update installation, Startup Disk control panel functioning, etc.
Depending on the firmware, some system may need this to properly edit files in the UEFI shell when unable to handle Tabs. This swaps it for spaces instead but the majority can ignore it but do note that ConsoleControl set to True may be needed
Fixes High resolutions displays that display OpenCore in 1024x768, recommended for users with 1080P+ displays
Needed for when half of the previously drawn image remains, will force black screen before switching to TextMode. Do note that ConsoleControl set to True may be needed
Some firmware block partition handles by opening them in By Driver mode, which results in File System protocols being unable to install. Mainly relevant for HP systems when no drives are listed
And now you're ready to save and place it into your EFI under EFI/OC.
For those having booting issues, please make sure to read the Troubleshooting section first and if your questions are still unanswered we have plenty of resources at your disposal:
So what in the world needs to be done once everything is installed? Well here are some things:
Correcting audio, reread the DeviceProperties on how
Moving OpenCore from the USB to your main drive
Mount USB's EFI
Copy EFI folder to the desktop
Unmount USB and mount boot drive's EFI
Paste EFI onto the root of the drive
