Configurating OpenCore for your x1c6

Critter

OpenCore is better than Clover in many ways. But since it is still in its infancy, OpenCore still requires a lot of time and personal confgurations to work. So even though I have posted my EFI-OpenCore folder, there are still some work which you have to do before you are able to get it working on your machine.

Fortunately, acidanthera has done a great job documenting OpenCore. And while it can be greatly time consuming, I really recommend taking a look at it and starting a config.plist from scratch. Doing so will allow you to personalize and understand OpenCore configurations. More importantly, by starting an config.plist from scratch, you may catch a mistake in my own config.plist or find a better setting variable.

I do, however, understand if you are strapped for time. So here are the necessary changes to my uploaded configs that would get your machine working. In most cases, your machine should boot with OpenCore after these changes. However, if it does not. please refer to acidanthera's OpenCore documentation.

* SystemUUID: Can be generated with MacSerial or use pervious from Clover's config.plist.
* MLB: Can be generated with MacSerial or use pervious from Clover's config.plist.
* ROM: ROM must either be Apple ROM (dumped from a real Mac), or your NIC MAC address, or any random MAC address (could be just 6 random bytes) - Vit9696
* SystemSerialNumber: Can be generated with MacSerial or use pervious from Clover's config.plist.

See docs/5_README-other for more details regarding PlatformInfo settings.

CPUFriendDataProvider can be generated with CPUFriendFriend or one-key-cpufriend. This is especially important if you have a different CPU than mine. Even if you have the same CPU as me, you may prefer a different Energy Performance Preference (EPP) so do generate your own CPUFriendDataProvider.

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 https://opencore.slowgeek.com/.

config.plist Comments:

  • Notes on kexts and ACPI patches are on the respective Add OpenCore entry.

  • Injects AppleALC layout-id 21:
    Device Properties > PciRoot(0x0)/Pci(0x1f,0x3) > layout-id:

  • Intel iGPU and HDMI patches: Device Properties > PciRoot(0x0)/Pci(0x2,0x0) >

  • 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

  • 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.

Updating:

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.
