Checking your OpenCore config.plist

It is important to keep your OpenCore config.plist properly up-to-spec, as OpenCore configurations tend to change accordingly with OpenCore versions. A good resource to check your config.plist is the ocvalidate binary that is bundled with every OpenCore releases.

config.plist Comments:

  • There are two plist files. Default config.plist is meant who those with a modded BIOS and have made the approiate settings as detailed in docs/ while config_unmoddedBIOS.plist is meant for those without a modded BIOS. If you have a modded BIOS and have made the adjustments detailed in my docs, config.plist should suffice. If your BIOS is unmodded, simply add the contents of config_unmoddedBIOS.plist to the main config.plist.
  • Notes on kexts and ACPI patches are on the respective OpenCore entries. Additionally, notes on ACPI patches can be found in docs/ as well as comments inside the patch.
  • Audio patches:
    Device Properties > PciRoot(0x0)/Pci(0x1f,0x3) > layout-id: Injects AppleALC layout-id 21
  • Intel iGPU and HDMI patches: Device Properties > PciRoot(0x0)/Pci(0x2,0x0) >
    • device-id = 16590000 per WhateverGreen/
    • AAPL,ig-platform-id = This is negotiable. In the future, I will test different variables for optimization. For now, 04002759 works well enough.
    • AAPL00,override-no-connect = EDID override to fix HDMI hotplug. Search for yours at patches/Internal Displays/ or see Issue #60 to create one for your display model.
    • framebuffer-con1-enable to enable framebuffer patching by WEG on connector 1.
    • framebuffer-con1-type to set connector 1 type to HDMI (per IOReg)
    • framebuffer-patch-enable tells WEG to patch framebuffer.
    • AAPL00,override-no-connect to override EDID (dependent on display models). See patches/Internal Displays/. This is necessary to fix HDMI hotplug. To create your own, see Issue #60
  • FileVault compatibility:
    • Misc -> Boot
      • PollAppleHotKeys set to YES(While not needed can be helpful)
    • Misc -> Security
      • AuthRestart set to YES(Enables Authenticated restart for FileVault 2 so password is not required on reboot. Can be considered a security risk so optional)
    • NVRAM -> Add -> 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14
      • UIScale set to 02 for high resolution small displays
    • UEFI -> Input
      • KeySupport set to YES(Only when using OpenCore's builtin input, users of OpenUsbKbDxe should avoid)
    • UEFI -> Output
      • ProvideConsoleGop to YES
    • UEFI -> ProtocolOverrides
      • FirmwareVolume set to YES
      • AppleSmcIo set to YES(this replaces VirtualSMC.efi)
    • UEFI -> Quirks
      • RequestBootVarRouting set to YES
  • Hibernation Mode 25 support:
    • Booter -> Quirks
    • DiscardHibernateMap set to YES
    • NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82
    • boot-args includes -hbfx-dump-nvram rtcfx_exclude=80-AB
    • Misc -> Boot
    • HibernateMode set to NVRAM
    • UEFI -> ReservedMemory
    • Address: 569344
    • Size: 4096
    • Type: RuntimeCode
  • Personalization:

    • ShowPicker is No. Use Esc during boot to show picker when needed.
    • PickerMode is External to use OpenCanopy boot menu. If you prefer a lighter EFI, delete Resources and switch variable to Builtin.
    • PlayChime is No. Set this to Yes if you want the native chime to play upon boot.
  • OpenCanopy Support:
    I prefer OpenCanopy for its looks. However, it is completely optional and can take up space in your EFI. If you would rather use OpenCore's built in picker. Change PickerMode to Builtin and remove OpenCanopy.efi from UEFI > Drivers.

  • OpenCore tools and utilities are removed for a clean setup and can be added when needed.


To update your OpenCore folder to my current version, simply backup your PlatformInfo information and move it to the new OpenCore config. Keep in mind that, depending on your setup, you may wish to keep other settings you've made so make sure to note your OpenCore config.plist changes as you make them.
