Config.plist

Checking your OpenCore config.plist

When editing config.plist, confirm proper syntax by running ocvalidate config.plist.

config.plist Comments:

  • The default config.plist is meant to serve a mostly vanilla configuration. Additional config.plist compoments are available in x1c6-hackintosh/patches/

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/IntelHD.en.md
  • 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.

EFI Tools

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