Laptop Ivy Bridge

Support	Version
Initial macOS Support	OS X 10.7, Lion
Last Supported OS	macOS 11, Big Sur

Starting Point

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

• ProperTree (opens new window)
  • Universal plist editor
• GenSMBIOS (opens new window)
  • For generating our SMBIOS data
• Sample/config.plist (opens new window)
  • See previous section on how to obtain: config.plist Setup

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.

ACPI

Add

Info

This is where you'll add SSDTs for your system, these are very important to booting macOS and have many uses like USB maps (opens new window), disabling unsupported GPUs and such. And with our system, it's even required to boot. Guide on making them found here: Getting started with ACPI (opens new window)

For us we'll need a couple of SSDTs to bring back functionality that Clover provided:

Required SSDTs	Description
SSDT-PM (opens new window)	Needed for proper CPU power management, you will need to run Pike's ssdtPRGen.sh script to generate this file. This will be run in post install (opens new window).
SSDT-EC (opens new window)	Fixes the embedded controller, see Getting Started With ACPI Guide (opens new window) for more details.
SSDT-XOSI (opens new window)	Makes all _OSI calls specific to Windows work for macOS (Darwin) Identifier. This may help enabling some features like XHCI and others.
SSDT-PNLF (opens new window)	Fixes brightness control, see Getting Started With ACPI Guide (opens new window) for more details. Note that Intel NUCs do not need this
SSDT-IMEI (opens new window)	Needed to add a missing IMEI device on Ivy Bridge CPU with 6 series motherboards, not needed for 7 series motherboards

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.

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 (opens new window) 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.

Delete

Info

This blocks certain ACPI tables from loading, for us we really care about this. Main reason is that Apple's XCPM does not support IvyBridge all too well and can cause AppleIntelCPUPowerManagement panics on boot. To avoid this we make our own PM SSDT in Post-Install (opens new window) and drop the old tables(Note that this is only temporary until we've made our SSDT-PM, we'll re-enable these tables later):

Removing CpuPm:

Key	Type	Value
All	Boolean	YES
Comment	String	Delete CpuPm
Enabled	Boolean	YES
OemTableId	Data	437075506d000000
TableLength	Number	0

Enabled	Boolean	YES
OemTableId	Data	4370753049737400
TableLength	Number	0
TableSignature	Data	53534454

Patch

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

Comment	String	Change _OSI to XOSI
Enabled	Boolean	YES
Count	Number	0
Limit	Number	0
Find	Data	5f4f5349
Replace	Data	584f5349

Quirks

Settings relating to ACPI, leave everything here as default as we have no use for these quirks.

Booter

This section is dedicated to quirks relating to boot.efi patching with OpenRuntime, the replacement for AptioMemoryFix.efi

MmioWhitelist

This section is allowing spaces to be pass-through to macOS that are generally ignored, useful when paired with DevirtualiseMmio

Quirks

Info

Settings relating to boot.efi patching and firmware fixes, for us, we leave it as default

More in-depth Info

• AvoidRuntimeDefrag: YES
  • Fixes UEFI runtime services like date, time, NVRAM, power control, etc
• EnableSafeModeSlide: YES
  • Enables slide variables to be used in safe mode.
• EnableWriteUnprotector: YES
  • Needed to remove write protection from CR0 register.
• ProvideCustomSlide: YES
  • Used for Slide variable calculation. However the necessity of this quirk is determined by OCABC: Only N/256 slide values are usable! message in the debug log. If the message OCABC: All slides are usable! You can disable ProvideCustomSlide! is present in your log, you can disable ProvideCustomSlide.
• SetupVirtualMap: YES
  • Fixes SetVirtualAddresses calls to virtual addresses, required for Gigabyte boards to resolve early kernel panics

DeviceProperties

Add

Sets device properties from a map.

PciRoot(0x0)/Pci(0x2,0x0)

This section is set up via WhateverGreen's Framebuffer Patching Guide (opens new window) and is used for setting important iGPU properties.

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:

1. When initially setting up your config.plist, only set AAPL,ig-platform-id - this is normally enough
2. 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.

AAPL,ig-platform-id	Type	Comment
03006601	Laptop	To be used with 1366 by 768 displays or lower
04006601	Laptop	To be used with 1600 by 900 displays or higher, see below for addition patches
09006601	Laptop	To be used with some devices that have eDP connected monitor (contrary to classical LVDS), must be tested with 03006601 and 04006601 first before trying this.
0B006601	NUC	To be used with Intel NUCs

Configuration Notes

• VGA is not supported (unless it's running through a DP to VGA internal adapter, which apparently only rare devices will see it as DP and not VGA, it's all about luck.)

• If you're using 04006601 as your ig-platform-id, you may need to add the following parameters to fix external outputs as otherwise you will only have one output. (Credit to Rehabman)

Key	Type	Value	Explanation
framebuffer-patch-enable	Number	1	enabling the semantic patches in principle (from the WhateverGreen manual)
framebuffer-memorycount	Number	2	Matching FBMemoryCount to the one on 03006601 (1 on 04 vs 2 on 03)
framebuffer-pipecount	Number	2	Matching PipeCount to the one on 03006601 (3 on 04 vs 2 on 03)
framebuffer-portcount	Number	4	Matching PortCount to the one on 03006601 (1 on 04 vs 4 on 03)
framebuffer-stolenmem	Data	00000004	Matching STOLEN memory to 64MB (0x04000000 from hex to base 10 in Bytes) to the one on 03006601 Check here (opens new window) for more information.
framebuffer-con1-enable	Number	1	This will enable patching on connector 1 of the driver. (Which is the second connector after con0, which is the eDP/LVDS one)
framebuffer-con1-alldata	Data	02050000 00040000 07040000 03040000 00040000 81000000 04060000 00040000 81000000	When using all data with a connector, either you give all information of that connector (port-bused-type-flag) or that port and the ones following it, like in this case. In this case, the ports in 04 are limited to 1: 05030000 02000000 30020000 (which corresponds to port 5, which is LVDS) However on 03 there are 3 extra ports: 05030000 02000000 30000000 (LVDS, con0, like 04) 02050000 00040000 07040000 (DP, con1) 03040000 00040000 81000000 (DP, con2) 04060000 00040000 81000000 (DP, con3) Since we changed the number of PortCount to 4 in a platform that has only 1, that means we need to define the 3 others (and we that starting with con1 to the end).

PciRoot(0x0)/Pci(0x16,0x0)

Sandy/IvyBridge Hybrids:

Some laptops from this era came with a mixed chipset setup, using Ivy Bridge CPUs with Sandy Bridge chipsets which creates issues with macOS since it expects a certain IMEI (opens new window) ID that it doesn't find and would get stuck at boot(As Apple's iGPU drivers require an IMEI device (opens new window)), to fix this we need to fake the IMEI's IDs in these models

• To know if you're affected check if your CPU is an Intel Core ix-3xxx and your chipset is Hx6x (for example a laptop with HM65 or HM67 with a Core i3-3110M) through tools like AIDA64.
• In your config add a new PciRoot device named PciRoot(0x0)/Pci(0x16,0x0)

Key	Type	Value
device-id	Data	3A1E0000

PciRoot(0x0)/Pci(0x1b,0x0)

layout-id

• 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 (opens new window).
• You can delete this property outright as it's unused for us at this time

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 Post-Install Page (opens new window)

Delete

Removes device properties from the map, for us we can ignore this

Kernel

Add

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:

More in-depth Info

The main thing you need to keep in mind is:

• Load order
  • Remember that any plugins should load after its dependencies
  • This means kexts like Lilu must come before VirtualSMC, AppleALC, WhateverGreen, etc

A reminder that ProperTree (opens new window) users can run Cmd/Ctrl + Shift + R to add all their kexts in the correct order without manually typing each kext out.

• Arch
  • Architectures supported by this kext
  • Currently supported values are Any, i386 (32-bit), and x86_64 (64-bit)
• BundlePath
  • Name of the kext
  • ex: Lilu.kext
• Enabled
  • Self-explanatory, either enables or disables the kext
• ExecutablePath
  • 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.
  • ex: Contents/MacOS/Lilu
• MinKernel
  • Lowest kernel version your kext will be injected into, see below table for possible values
  • ex. 12.00.00 for OS X 10.8
• MaxKernel
  • Highest kernel version your kext will be injected into, see below table for possible values
  • ex. 11.99.99 for OS X 10.7
• PlistPath
  • Path to the info.plist hidden within the kext
  • ex: Contents/Info.plist

Kernel Support Table

OS X Version	MinKernel	MaxKernel
10.4	8.0.0	8.99.99
10.5	9.0.0	9.99.99

14	23.0.0	23.99.99
15	24.0.0	24.99.99

Emulate

Needed for spoofing unsupported CPUs like Pentiums and Celerons

• Cpuid1Mask: Leave this blank
• Cpuid1Data: Leave this blank

Force

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.

Block

Blocks certain kexts from loading. Not relevant for us.

Patch

Patches both the kernel and kexts.

Quirks

Info

Settings relating to the kernel, for us we'll be changing the following:

Quirk	Enabled	Comment
AppleCpuPmCfgLock	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+

More in-depth Info

• AppleCpuPmCfgLock: YES
  • Only needed when CFG-Lock can't be disabled in BIOS
  • Only applicable for Ivy Bridge and older
    • Note: Broadwell and older require this when running 10.10 or older
• AppleXcpmCfgLock: NO
  • Only needed when CFG-Lock can't be disabled in BIOS
  • Only applicable for Haswell and newer
    • Note: Ivy Bridge-E is also included as it's XCPM capable
• CustomSMBIOSGuid: NO
  • Performs GUID patching for UpdateSMBIOSMode set to Custom. Usually relevant for Dell laptops
  • Enabling this quirk with UpdateSMBIOSMode Custom mode can also disable SMBIOS injection into "non-Apple" OSes however we do not endorse this method as it breaks Bootcamp compatibility. Use at your own risk
• DisableIoMapper: YES
  • 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
• DisableIoMapperMapping: NO
  • Needed if you are experiencing issues with Wi-Fi/Ethernet/Thunderbolt with VT-D enabled and more than 16GB of memory installed. This quirk requires a patched DMAR table (opens new window) with Reserved Memory Regions removed
  • We recommend disabling VT-D, so we don't need this enabled
  • Not needed for 13.2.1 and lower
• DisableLinkeditJettison: YES
  • Allows Lilu and others to have more reliable performance without keepsyms=1
• DisableRtcChecksum: NO
  • Prevents AppleRTC from writing to primary checksum (0x58-0x59), required for users who either receive BIOS reset or are sent into Safe mode after reboot/shutdown
• ExtendBTFeatureFlags NO
  • Helpful for those having continuity issues with non-Apple/non-Fenvi cards
• LapicKernelPanic: NO
  • Disables kernel panic on AP core lapic interrupt, generally needed for HP systems. Clover equivalent is Kernel LAPIC
• LegacyCommpage: NO
  • Resolves SSSE3 requirement for 64 Bit CPUs in macOS, mainly relevant for 64-Bit Pentium 4 CPUs(ie. Prescott)
• PanicNoKextDump: YES
  • Allows for reading kernel panics logs when kernel panics occur
• PowerTimeoutKernelPanic: YES
  • Helps fix kernel panics relating to power changes with Apple drivers in macOS Catalina, most notably with digital audio.
• SetApfsTrimTimeout: -1
  • Sets trim timeout in microseconds for APFS filesystems on SSDs, only applicable for macOS 10.14 and newer with problematic SSDs.
• XhciPortLimit: YES
  • 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 (opens new window) when possible.
  • With macOS 11.3+, XhciPortLimit may not function as intended. (opens new window) We recommend users either disable this quirk and map before upgrading or map from Windows (opens new window). You may also install macOS 11.2.3 or older.

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

Scheme

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:

More in-depth Info

• FuzzyMatch: True

  • Used for ignoring checksums with kernelcache, instead opting for the latest cache available. Can help improve boot performance on many machines in 10.6

• KernelArch: x86_64

  • Set the kernel's arch type, you can choose between Auto, i386 (32-bit), and x86_64 (64-bit).
  • If you're booting older OSes which require a 32-bit kernel(ie. 10.4 and 10.5) we recommend to set this to Auto and let macOS decide based on your SMBIOS. See below table for supported values:
    • 10.4-10.5 — x86_64, i386 or i386-user32
      • i386-user32 refers 32-bit userspace, so 32-bit CPUs must use this(or CPUs missing SSSE3)
      • x86_64 will still have a 32-bit kernelspace however will ensure 64-bit userspace in 10.4/5
    • 10.6 — i386, i386-user32, or x86_64
    • 10.7 — i386 or x86_64
    • 10.8 or newer — x86_64

• KernelCache: Auto

  • Set kernel cache type, mainly useful for debugging and so we recommend Auto for best support

Misc

Boot

Info

Quirk	Enabled	Comment
HideAuxiliary	YES	Press space to show macOS recovery and other auxiliary entries

More in-depth Info

• HideAuxiliary: YES
  • This option will hide supplementary entries, such as macOS recovery and tools, in the picker. Hiding auxiliary entries may increase boot performance on multi-disk systems. You can press space at the picker to show these entries

Debug

Info

Helpful for debugging OpenCore boot issues(We'll be changing everything but DisplayDelay):

Quirk	Enabled
AppleDebug	YES
ApplePanic	YES
DisableWatchDog	YES
Target	67

More in-depth Info

• AppleDebug: YES
  • Enables boot.efi logging, useful for debugging. Note this is only supported on 10.15.4 and newer
• ApplePanic: YES
  • Attempts to log kernel panics to disk
• DisableWatchDog: YES
  • Disables the UEFI watchdog, can help with early boot issues
• DisplayLevel: 2147483650
  • Shows even more debug information, requires debug version of OpenCore
• SysReport: NO
  • Helpful for debugging such as dumping ACPI tables
  • Note that this is limited to DEBUG versions of OpenCore
• Target: 67
  • Shows more debug information, requires debug version of OpenCore

These values are based of those calculated in OpenCore debugging

Security

Info

Security is pretty self-explanatory, do not skip. We'll be changing the following:

Quirk	Enabled	Comment
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

More in-depth Info

• AllowSetDefault: YES

  • Allow CTRL+Enter and CTRL+Index to set default boot device in the picker

• ApECID: 0

  • Used for netting personalized secure-boot identifiers, currently this quirk is unreliable due to a bug in the macOS installer so we highly encourage you to leave this as default.

• AuthRestart: NO

  • Enables Authenticated restart for FileVault 2 so password is not required on reboot. Can be considered a security risk so optional

• BlacklistAppleUpdate: YES

  • Used for blocking firmware updates, used as extra level of protection as macOS Big Sur no longer uses run-efi-updater variable

• DmgLoading: Signed

  • Ensures only signed DMGs load

• ExposeSensitiveData: 6

  • Shows more debug information, requires debug version of OpenCore

• Vault: Optional

  • We won't be dealing vaulting so we can ignore, you won't boot with this set to Secure
  • 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

• ScanPolicy: 0

  • 0 allows you to see all drives available, please refer to Security (opens new window) section for further details. Will not boot USB devices with this set to default

• SecureBootModel: Default

  • Controls Apple's secure boot functionality in macOS, please refer to Security (opens new window) 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: Stuck on OCB: LoadImage failed - Security Violation

Serial

Used for serial debugging (Leave everything as default).

Tools

Used for running OC debugging tools like the shell, ProperTree's snapshot function will add these for you.

Entries

Used for specifying irregular boot paths that can't be found naturally with OpenCore.

Won't be covered here, see 8.6 of Configuration.pdf (opens new window) for more info

NVRAM

Add

4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14

Used for OpenCore's UI scaling, default will work for us. See in-depth section for more info

More in-depth Info

Booter Path, mainly used for UI modification

• DefaultBackgroundColor: Background color used by boot.efi
  • 00000000: Syrah Black
  • BFBFBF00: Light Gray

4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102

OpenCore's NVRAM GUID, mainly relevant for RTCMemoryFixup users

More in-depth Info

• rtc-blacklist: <>
  • To be used in conjunction with RTCMemoryFixup, see here for more info: Fixing RTC write issues (opens new window)
  • Most users can ignore this section

7C436110-AB2A-4BBB-A880-FE41995C9F82

System Integrity Protection bitmask

• General Purpose boot-args:

boot-args	Description
-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 (opens new window) to figure out which layout to use for your specific system. More info on this is covered in the Post-Install Page (opens new window)

• GPU-Specific boot-args:

boot-args	Description
-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

• csr-active-config: 00000000

  • Settings for 'System Integrity Protection' (SIP). It is generally recommended to change this with csrutil via the recovery partition.
  • 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: Disabling SIP

• 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)
  • Full list can be found in AppleKeyboardLayouts.txt (opens new window)
  • 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.

Key	Type	Value
prev-lang:kbd	String	en-US:0

Delete

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.

PlatformInfo

Info

For setting up the SMBIOS info, we'll use CorpNewt's GenSMBIOS (opens new window) application.

For this Ivy Bridge example, we'll chose the iMac13,2 SMBIOS - this is done intentionally for compatibility's sake. The typical breakdown is as follows:

SMBIOS	CPU Type	GPU Type	Display Size
MacBookAir5,1	Dual Core 17W	iGPU: HD 4000	11"
MacBookAir5,2	Dual Core 17W	iGPU: HD 4000	13"
MacBookPro10,1	Quad Core 45W	iGPU: HD 4000 + dGPU: GT 650M	15"
MacBookPro10,2	Dual Core 35W(High End)	iGPU: HD 4000	13"
Macmini6,1	Dual Core NUC	iGPU: HD 4000	N/A
Macmini6,2	Quad Core NUC	iGPU: HD 4000	N/A

Note: The following SMBIOS are only supported up-to and including macOS 10.15, Catalina. For cases where you must boot Big Sur, see below:

Big Sur SMBIOS table

Note choosing a SMBIOS from the list below for Catalina or older is not recommended, as Power Management and such can break when using unoptimized SMBIOS.

SMBIOS	CPU Type	Display Size
MacBookAir6,1	Dual Core 15W	11"
MacBookAir6,2	Dual Core 15W	13"
MacBookPro11,1	Dual Core 28W	13"
MacBookPro11,2	Quad Core 45W	15"
MacBookPro11,3	Quad Core 45W	15"
MacBookPro11,4	Quad Core 45W	15"
MacBookPro11,5	Quad Core 45W	15"
Macmini7,1	NUC Systems	N/A

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:

SmUUID:       A154B586-874B-4E57-A1FF-9D6E503E4580

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.

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 (opens new window) page on how to find your real MAC Address)

Reminder that you need an invalid serial! When inputting your serial number in Apple's Check Coverage Page (opens new window), you should get a message such as "Unable to check coverage for this serial number."

Automatic: YES

• Generates PlatformInfo based on Generic section instead of DataHub, NVRAM, and SMBIOS sections

:::

Generic

More in-depth Info

• AdviseFeatures: NO

  • Used for when the EFI partition isn't first on the Windows drive

• MaxBIOSVersion: NO

  • Sets BIOS version to Max to avoid firmware updates in Big Sur+, mainly applicable for genuine Macs.

• ProcessorType: 0

  • Set to 0 for automatic type detection, however this value can be overridden if desired. See AppleSmBios.h (opens new window) for possible values

• SpoofVendor: YES

  • Swaps vendor field for Acidanthera, generally not safe to use Apple as a vendor in most case

• SystemMemoryStatus: Auto

  • Sets whether memory is soldered or not in SMBIOS info, purely cosmetic and so we recommend Auto

• UpdateDataHub: YES

  • Update Data Hub fields

• UpdateNVRAM: YES

  • Update NVRAM fields

• UpdateSMBIOS: YES

  • Updates SMBIOS fields

• UpdateSMBIOSMode: Create

  • Replace the tables with newly allocated EfiReservedMemoryType, use Custom on Dell laptops requiring CustomSMBIOSGuid quirk
  • Setting to Custom with CustomSMBIOSGuid quirk enabled can also disable SMBIOS injection into "non-Apple" OSes however we do not endorse this method as it breaks Bootcamp compatibility. Use at your own risk

UEFI

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.

Drivers

Add your .efi drivers here.

Only drivers present here should be:

• HfsPlus.efi
• OpenRuntime.efi

More in-depth Info

Key	Type	Description
Path	String	Path of the file from OC/Drivers directory
LoadEarly	Boolean	Load the driver early before NVRAM setup, should only be enabled for OpenRuntime.efi and OpenVariableRuntimeDxe.efi if using legacy NVRAM
Arguments	String	Some drivers accept additional arguments which are specified here.

APFS

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.

macOS Version	Min Version	Min Date
High Sierra (10.13.6)	748077008000000	20180621
Mojave (10.14.6)	945275007000000	20190820
Catalina (10.15.4)	1412101001000000	20200306
No restriction	-1	-1

Audio

Related to AudioDxe settings, for us we'll be ignoring(leave as default). This is unrelated to audio support in macOS.

• For further use of AudioDxe and the Audio section, please see the Post Install page: Add GUI and Boot-chime (opens new window)

Input

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: Security and FileVault (opens new window)

Output

Relating to OpenCore's visual output, leave everything here as default as we have no use for these quirks.

More in-depth Info

Output	Value	Comment
UIScale	0	0 will automatically set based on resolution -1 will leave it unchanged 1 for 1x scaling, for normal displays 2 for 2x scaling, for HiDPI displays

ProtocolOverrides

Mainly relevant for Virtual machines, legacy macs and FileVault users. See here for more details: Security and FileVault (opens new window)

Quirks

Info

Relating to quirks with the UEFI environment, for us we'll be changing the following:

Quirk	Enabled	Comment
IgnoreInvalidFlexRatio	YES
ReleaseUsbOwnership	YES
UnblockFsConnect	NO	Needed mainly by HP motherboards

More in-depth Info

• IgnoreInvalidFlexRatio: YES

  • Fix for when MSR_FLEX_RATIO (0x194) can't be disabled in the BIOS, required for all pre-Skylake based systems

• ReleaseUsbOwnership: YES

  • Releases USB controller from firmware driver, needed for when your firmware doesn't support EHCI/XHCI Handoff. Most laptops have garbage firmwares so we'll need this as well

• DisableSecurityPolicy: NO

  • Disables platform security policy in firmware, recommended for buggy firmwares where disabling Secure Boot does not allow 3rd party firmware drivers to load.
  • If running a Microsoft Surface device, recommended to enable this option

• RequestBootVarRouting: YES

  • Redirects AptioMemoryFix from EFI_GLOBAL_VARIABLE_GUID to 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.

• UnblockFsConnect: NO

  • 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

ReservedMemory

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

Cleaning up

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:

• r/Hackintosh Subreddit (opens new window)
• r/Hackintosh Discord (opens new window)

Config reminders

HP Users:

• Kernel -> Quirks -> LapicKernelPanic -> True
  • You will get a kernel panic on LAPIC otherwise
• UEFI -> Quirks -> UnblockFsConnect -> True

Intel BIOS settings

• Note: Most of these options may not be present in your firmware, we recommend matching up as closely as possible but don't be too concerned if many of these options are not available in your BIOS

These are the main options to check for, if you can't find it or an equivalent for it, just skip it.

Disable

• Fast Boot
• Secure Boot
• Serial/COM Port
• Parallel Port
• VT-d (can be enabled if you set DisableIoMapper to YES)
• Compatibility Support Module (CSM) (Must be off in most cases, GPU errors/stalls like gIO are common when this option is enabled) (or Legacy Support, or Hybrid Boot)
• Thunderbolt (For initial install, as Thunderbolt can cause issues if not setup correctly, if available)
• Intel SGX
• Intel Platform Trust
• CFG Lock (MSR 0xE2 write protection)(This must be off, if you can't find the option then enable AppleCpuPmCfgLock under Kernel -> Quirks. Your hack will not boot with CFG-Lock enabled)

Enable

• VT-x (Virtualization Support)
• Above 4G Decoding
• Hyper-Threading
• Execute Disable Bit
• EHCI/XHCI Hand-off
• OS type: Windows 8.1/10 UEFI Mode (some motherboards may require "Other OS" instead)
• DVMT Pre-Allocated(iGPU Memory): 32MB or higher
• SATA Mode: AHCI

Once done here, we need to edit a couple extra values. Head to the Apple Secure Boot Page
