So making a config.plist may seem hard, its not. It just takes some time but this guide will tell you how to configure eveything, 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, we'll need some things to get started:
ProperTree: For editing our config, this editor has some super useful tools for OpenCore
GenSMBIOS: For generating our SMBIOS
Sample.plist: This is found under the Docs folder of the release download
Now with those downloaded, we can get to really get started:
Grab the Sample.plist and rename to config.plist
Open your new config.plist in ProperTree
Run the Clean Snapshot function(Cmd/Ctrl + Shift + R and point it at your EFI/OC folder),
This will remove all the entries from the config.plist and then adds all your SSDTs, Kexts and Firmware drivers to the config
Cmd+R is another option that will add all your files as well but will leave entries disabled if they were set like that before, useful for when you're troubleshooting
And now you're ready to configure it!
And 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.
This is where you'll add SSDTs for your system, these are very important to booting macOS and have many uses like USB maps, disabling unsupported GPUs and such. And with our system, its even required to boot. Guide on making them found here: Getting started with ACPI
For us we'll need a couple of SSDTs to bring back functionality that Clover provided:
Allows for native CPU power management on Haswell and newer, Clover alternative would be under
Acpi -> GenerateOptions -> PluginType
Hides the Embedded controller and creates a fake one for macOS, needed for all Catalina users and recommended for other versions of macOS
Prefered alternative over renaming EHCI for setting up USB correctly on pre-skylake systems. This can be avoided if your BIOS supports EHCI-Handoff
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/ACPI.
For those wanting a deeper dive into dumping your DSDT, how to make these SSDTs, and compiling them, please see the Getting started with ACPI 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.
This blocks 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. For us, our patches are handled by our SSDTs. This is a much cleaner solution as this will allow us to boot Windows and other OSes with OpenCore
Settings relating to ACPI, leave everything here as default.
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, for us we can ignore this section.
Settings relating to boot.efi patching and firmware fixes, default will work for us
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
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 artifacts 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
Tricks the hardware into thinking its always booting macOS, mainly benifitial for MacBook Pro's with dGPUs as booting Windows won't allow for the iGPU to be used
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:
0x0D220003 - this is used when the iGPU is used to drive a display
0300220D when hex-swapped
0x04120004 - this is used when the iGPU is only used for computing tasks and doesn't drive a display
04001204 when hex-swapped
I added another portion as well that shows a
device-id fake in case you have an HD 4400 which is unsupported in macOS.
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:
0x04120000 - this is the device id for HD 4600 which does have support in macOS
12040000 when hex swapped
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.
For us, we'll be using the boot-arg
alcid=xxx instead to accomplish this.
alcid will override all other layout-IDs present
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 + Shift + 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 is hidden within the kext, you can see what path your 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(AMD CPUs don't require this)
CpuidMask: Leave this blank
CpuidData: Leave this blank
Block: Blocks kexts from loading. Not relevant for us
Patch: Patches both the kernel and kexts
Settings relating to the kernel, for us we'll be enabling
XhciPortLimit. Everything else should be left as default
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 many Xeons. Skylake-X can ignore
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
New alternative to NullCPUPowerManagement, required for all AMD CPU based systems as there's no native power management. Intel can ignore
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 everything as default)
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
Used to add a delay for hotkeys when OpenCore is a bit to fast to register, 5000-10000 microseconds is the prefered range for users with broken hotkeys support
Uses OpenCore's default GUI, set to NO if you wish to use a different GUI
Debug: Helpful for debuggin OpenCore boot issues(We'll be chnging everything but
DisableWatchDog: YES (May need to be set for YES if OpenCore is stalling on something while booting, can also help for early macOS boot issues)
Shows more debug information, requires debug version of OpenCore
Shows even more debug information, requires debug version of OpenCore
These values are based of those calculated in OpenCore debugging
Security: Security is pretty self-explanatory, do not skip
We'll be changing
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 security risk so optional
Shows more debug information, requires debug version of OpenCore
We won't be dealing vaulting so we can ignore, won't boot with this enabled
We won't be dealing vaulting so we can ignore as well, won't boot with this enabled
0 allows you to see all drives available, please refer to Security section for further details. Will not boot USBs with this set to default
Tools Used for running OC debugging tools like the shell, ProperTree's snapshot function will add these for you. For us, we won't be using any tools
Name shown in OpenCore
Self-explanatory, enables or disables
Path to file after the
Entries: Used for specifying irregular boot paths that can't be found naturally with OpenCore
Name shown in boot picker
Self-explanatory, enables or disables
PCI route of boot drive, can be found with the OpenCoreShell and the
4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14 (Booter Path, mainly used for UI Scaling)
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.
alcid=1 - used for setting layout-id for AppleALC, see supported codecs to figure out which layout to use for your specific system.
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
00000000 which enables System Integrity Protection. 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
Recommended to leave enabled for best security practices
Needed for non-latin keyboards in the format of
lang-COUNTRY:keyboard, recommeneded to keep 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 alone.
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 Haswell example, we chose the iMac15,1 SMBIOS. The typical breakdown is as follows:
Haswell with only iGPU
Haswell with dGPU
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:
######################################################## iMac15,1 SMBIOS Info ########################################################Type: iMac15,1Serial: C02M9SYJFY10Board Serial: C02408101J9G2Y7A8SmUUID: 7B227BEC-660D-405F-8E60-411B3E4EF055
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
11223300 0000. After install follow the Fixing iServices page on how to find your real MAC Address)
Reminder that you want either an invalid serial or valid serial numbers but those not in use, you want to get a message back like: "Invalid Serial" or "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, everything should be left as default
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, the one we care about is
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)
Settings relating to UEFI, main ones we need to change:
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 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:
VT-d(can be enabled if you set
DisableIoMapper to YES)
Intel Platform Trust
CFG Lock(MSR 0xE2 write protection)(This must be off, if you can't find the option then enable both
AppleXcpmCfgLock under Kernel -> Quirks. Your hack will not boot with CFG-Lock enabled)
Above 4G decoding
Execute Disable Bit
OS type: Windows 8.1/10 UEFI Mode
So what in the world needs to be done once everything is installed? Well here's some things you can do:
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
