So making a config.plist may seem hard, it's not. It just takes some time but this guide will tell you how to configure everything, you won't be left in the cold. This also means if you have issues, review your config settings to make sure they're correct. Main things to note with OpenCore:
All properties must be defined, there are no default OpenCore will fall back on so do not delete sections unless told explicitly so. If the guide doesn't mention the option, leave it at default.
The Sample.plist cannot be used As-Is, you must configure it to your system
DO NOT USE CONFIGURATORS, these rarely respect OpenCore's configuration and even some like Mackie's will add Clover properties and corrupt plists!
Now with all that, a quick reminder of the tools we need
Universal plist editor
For generating our SMBIOS data
See previous section on how to obtain:
WARNING
Read this guide more than once before setting up OpenCore and make sure you have it set up correctly. 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.
Info
For us we'll need a couple of SSDTs to bring back functionality that Clover provided:
Note that you should not add your generated DSDT.aml here, it is already in your firmware. So if present, remove the entry for it in your config.plist and under EFI/OC/ACPI.
This blocks certain ACPI tables from loading, for us we can ignore this.
Info
This section allows us to dynamically modify parts of the ACPI (DSDT, SSDT, etc.) via OpenCore. For us, we'll need the following:
OSI rename
This is required when using SSDT-XOSI as we redirect all OSI calls to this SSDT, this is not needed if you're using SSDT-GPIO

Settings relating to ACPI, leave everything here as default as we have no use for these quirks.
This section is dedicated to quirks relating to boot.efi patching with OpenRuntime, the replacement for AptioMemoryFix.efi
This section is allowing devices to be pass-through to macOS that are generally ignored, for us we can ignore this section.
Info
Settings relating to boot.efi patching and firmware fixes, for us, we need to change the following:
DevirtualiseMmio
YES
EnableWriteUnprotector
NO
ProtectMemoryRegions
YES
Only for Chromebooks, leave disabled otherwise.
ProtectUefiServices
YES
RebuildAppleMemoryMap
YES
SyncRuntimePermissions
YES
Sets device properties from a map.
PciRoot(0x0)/Pci(0x2,0x0)
The config.plist doesn't already have a section for this so you will have to create it manually.
When setting up your iGPU, the table below should help with finding the right values to set. Here is an explanation of some values:
AAPL,ig-platform-id
This is used internally for setting up the iGPU
Type
Whether the entry is recommended for laptops(ie. with built-in displays) or for Intel NUCs(ie. stand alone boxes)
Generally follow these steps when setting up your iGPU properties. Follow the configuration notes below the table if they say anything different:
When initially setting up your config.plist, only set AAPL,ig-platform-id - this is normally enough
If you boot and you get no graphics acceleration (7MB VRAM and solid background for dock), then you likely need to try different AAPL,ig-platform-id values, add stolenmem patches, or even add a device-id property.
0900A53E
Laptop
Recommended value for UHD 630
00009B3E
Laptop
Recommended value for UHD 620
07009B3E
NUC
Recommended value for UHD 620/630
0000A53E
NUC
Recommended value for UHD 655
For UHD 630 you likely do not need to fake the device-id as it is already 0x3E9B. If it's anything else, you may use device-id=9B3E0000:
You can check under Device Manager in Windows by bring up the iGPU, opening properties, selecting details, and clicking Hardware IDs.
device-id

9B3E0000
A UHD 620 in a Comet Lake CPU requires device-id=9B3E0000:

Data
9B3E0000
In some cases where you cannot set the DVMT-prealloc of these cards to 64MB higher in your UEFI Setup, you may get a kernel panic. Usually they're configured for 32MB of DVMT-prealloc, in that case these values are added to your iGPU Properties

You can delete this property outright as it's unused for us at this time
Removes device properties from the map, for us we can ignore this
Here's where we specify which kexts to load, in what specific order to load, and what architectures each kext is meant for. By default we recommend leaving what ProperTree has done, however for 32-bit CPUs please see below:
Needed for spoofing unsupported CPUs like Pentiums and Celerons. For those with Coffee Lake Plus you can skip this section, but for those with Comet Lake CPUs see below
Used for loading kexts off system volume, only relevant for older operating systems where certain kexts are not present in the cache(ie. IONetworkingFamily in 10.6).
For us, we can ignore.
Blocks certain kexts from loading. Not relevant for us.
Patches both the kernel and kexts.
Info
Settings relating to the kernel, for us we'll be enabling the following:
AppleXcpmCfgLock
YES
Not needed if CFG-Lock is disabled in the BIOS
DisableIoMapper
YES
Not needed if VT-D is disabled in the BIOS
LapicKernelPanic
NO
HP Machines will require this quirk
PanicNoKextDump
YES
PowerTimeoutKernelPanic
YES
XhciPortLimit
YES
Disable if running macOS 11.3+
Settings related to legacy booting(ie. 10.4-10.6), for majority you can skip however for those planning to boot legacy OSes you can see below:
Info
HideAuxiliary
YES
Press space to show macOS recovery and other auxiliary entries
Info
Helpful for debugging OpenCore boot issues(We'll be changing everything but DisplayDelay):
AppleDebug
YES
ApplePanic
YES
DisableWatchDog
YES
Target

Info
Security is pretty self-explanatory, do not skip. We'll be changing the following:
AllowSetDefault
YES
BlacklistAppleUpdate
YES
ScanPolicy
0
SecureBootModel
Default
Leave this as Default for OpenCore to automatically set the correct value corresponding to your SMBIOS. The next page goes into more detail about this setting.
Vault
Optional
This is a word, it is not optional to omit this setting. You will regret it if you don't set it to Optional, note that it is case-sensitive
Used for serial debugging (Leave everything as default).
Used for running OC debugging tools like the shell, ProperTree's snapshot function will add these for you.
Used for specifying irregular boot paths that can't be found naturally with OpenCore.
4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14
Used for OpenCore's UI scaling, default will work for us. See in-depth section for more info
4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102
OpenCore's NVRAM GUID, mainly relevant for RTCMemoryFixup users
7C436110-AB2A-4BBB-A880-FE41995C9F82
System Integrity Protection bitmask
General Purpose boot-args:
-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.
alcid=1
GPU-Specific boot-args:
-wegnoegpu
Used for disabling all other GPUs than the integrated Intel iGPU, useful for those wanting to run newer versions of macOS where their dGPU isn't supported
-igfxnotelemetryload
csr-active-config: 00000000
Settings for 'System Integrity Protection' (SIP). It is generally recommended to change this with csrutil via the recovery partition.
run-efi-updater: No
This is used to prevent Apple's firmware update packages from installing and breaking boot order; this is important as these firmware updates (meant for Macs) will not work.
prev-lang:kbd: <>
Needed for non-latin keyboards in the format of lang-COUNTRY:keyboard, recommended to keep blank though you can specify it(Default in Sample config is Russian):
American: en-US:0(656e2d55533a30 in HEX)
Hint: prev-lang:kbd can be changed into a String so you can input en-US:0 directly instead of converting to HEX
Hint 2: prev-lang:kbd can be set to a blank variable (eg. <>) which will force the Language Picker to appear instead at first boot up.
prev-lang:kbd
String
en-US:0
Forcibly rewrites NVRAM variables, do note that Add will not overwrite values already present in NVRAM so values like boot-args should be left alone.
LegacySchema
Used for assigning NVRAM variables, used with OpenVariableRuntimeDxe.efi. Only needed for systems without native NVRAM
WriteFlash: YES
Enables writing to flash memory for all added variables.
Info
For this Coffee Lake Plus example, we'll chose the MacBookPro16,1 SMBIOS - this is done intentionally for compatibility's sake. The breakdown is as follows(note that the below SMBIOS require macOS 10.15, Catalina):
MacBookPro16,1
Hexa/Octa Core 45W
iGPU: UHD 630 + dGPU: 5300/5500M
15"
Yes
MacBookPro16,3
Quad Core 15W
iGPU: Iris 645
13"
Yes
MacBookPro16,4
Hexa/Octa Core 45W
iGPU: UHD 630 + dGPU: 5600M
15"
Yes
Macmini8,1
NUC Systems
HD 6000/Iris Pro 6200
N/A
No
Run GenSMBIOS, pick option 1 for downloading MacSerial and Option 3 for selecting out SMBIOS. This will give us an output similar to the following:
Note: MacSerial currently does not support Linux, so you must grab a Windows or macOS machine to generate the MacBookPro16,2+ values
The Type part gets copied to Generic -> SystemProductName.
The Serial part gets copied to Generic -> SystemSerialNumber.
The Board Serial part gets copied to Generic -> MLB.
The SmUUID part gets copied to Generic -> SystemUUID.
Automatic: YES
Generates PlatformInfo based on Generic section instead of DataHub, NVRAM, and SMBIOS sections
ConnectDrivers: YES
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.
Add your .efi drivers here.
Only drivers present here should be:
HfsPlus.efi
OpenRuntime.efi
By default, OpenCore only loads APFS drivers from macOS Big Sur and newer. If you are booting macOS Catalina or earlier, you may need to set a new minimum version/date. Not setting this can result in OpenCore not finding your macOS partition!
macOS Sierra and earlier use HFS instead of APFS. You can skip this section if booting older versions of macOS.
APFS Versions
Both MinVersion and MinDate need to be set if changing the minimum version.
High Sierra (10.13.6)

Related to AudioDxe settings, for us we'll be ignoring(leave as default). This is unrelated to audio support in macOS.
Relating to OpenCore's visual output, leave everything here as default as we have no use for these quirks.
Info
Relating to quirks with the UEFI environment, for us we'll be changing the following:
ReleaseUsbOwnership
YES
UnblockFsConnect
NO
Needed mainly by HP motherboards
Used for exempting certain memory regions from OSes to use, mainly relevant for Sandy Bridge iGPUs or systems with faulty memory. Use of this quirk is not covered in this guide
Initial macOS Support()
Initial macOS Support()
This is where you'll add SSDTs for your system, these are very important to booting macOS and have many uses like , and such. And with our system, it's even required to boot. Guide on making them found here:
Allows for native CPU power management on Haswell and newer, see for more details.
Fixes both the embedded controller and USB power, see for more details.
Creates a stub so VoodooI2C can connect, for those having troubles getting VoodooI2C working can try instead. Note that Intel NUCs do not need this
Fixes brightness control, see for more details. Note that Intel NUCs do not need this
This is the , required for most B360, B365, H310, H370, Z390 and some Z370 boards which prevent systems from booting macOS. The alternative is for when AWAC SSDT is incompatible due to missing the Legacy RTC clock, to check whether you need it and which to use please see page.
So true 300 series motherboards(non-Z370) don't declare the FW chip as MMIO in ACPI and so XNU ignores the MMIO region declared by the UEFI memory map. This SSDT brings back NVRAM support. Note that 10th gen CPUs do not need this. See for more details.
For those wanting a deeper dive into dumping your DSDT, how to make these SSDTs, and compiling them, please see the page. Compiled SSDTs have a .aml extension(Assembled) and will go into the EFI/OC/ACPI folder and must be specified in your config under ACPI -> Add as well.
However, due to issues with OEMs not using the latest EDKII builds you may find that the above combo will result in early boot failures. This is due to missing the MEMORY_ATTRIBUTE_TABLE and such we recommend disabling RebuildAppleMemoryMap and enabling EnableWriteUnprotector. More info on this is covered in the
This section is set up via WhateverGreen's and is used for setting important iGPU properties.
Configuration Notes
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. .
For us, we'll be using the boot argument alcid=xxx instead to accomplish this. alcid will override all other layout-IDs present. More info on this is covered in the
A reminder that users can run Cmd/Ctrl + Shift + R to add all their kexts in the correct order without manually typing each kext out.
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 when possible.
With macOS 11.3+, We recommend users either disable this quirk and map before upgrading or . You may also install macOS 11.2.3 or older.
These values are based of those calculated in
0 allows you to see all drives available, please refer to section for further details. Will not boot USB devices with this set to default
Controls Apple's secure boot functionality in macOS, please refer to section for further details.
Note: Users may find upgrading OpenCore on an already installed system can result in early boot failures. To resolve this, see here:
Won't be covered here, see 8.6 of for more info
To be used in conjunction with RTCMemoryFixup, see here for more info:
Used for setting layout-id for AppleALC, see to figure out which layout to use for your specific system. More info on this is covered in the
Prevents iGPU telemetry from loading. iGPU telemetry may cause a freeze during startup on certain laptops such as Chromebooks on macOS 10.15 and higher, see for more information.
csr-active-config by default is set to 00000000 which enables System Integrity Protection. You can choose a number of different values but overall we recommend keeping this enabled for best security practices. More info can be found in our troubleshooting page:
Full list can be found in
For setting up the SMBIOS info, we'll use CorpNewt's application.
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 11223300 0000. After install follow the page on how to find your real MAC Address)
Reminder that you need an invalid serial! When inputting your serial number in , you should get a message such as "Unable to check coverage for this serial number."
Set to 0 for automatic type detection, however this value can be overridden if desired. See for possible values
For further use of AudioDxe and the Audio section, please see the Post Install page:
Related to boot.efi keyboard passthrough used for FileVault and Hotkey support, leave everything here as default as we have no use for these quirks. See here for more details:
