EFI Folders

Version	Description
Big Sur	Is mostly deprecated and will not be provided any support.
Monterey	Stable and up-to-date version of this EFI, provides a decent out-of-the-box experience.
Monterey - Experimental	Mostly for testing, should not be used as the daily driver. But can provide fixes for issues that may be in the stable build.

CFG-Lock

You need to disable CFG-Lock in order to boot this EFI!

Use this specific version of grub_setup_var

BIOS	CFG Lock	Overclock Lock
1.9.0, 1.12.1, 1.13.0	setup_var CpuSetup 0x3E 0x0	setup_var CpuSetup 0xDA 0x0

CPU

The i7-10710U needs Cpuid1Data and Cpuid1Mask patches in OpenCore to prevent very early kernel panics. Power managment works as expected after using CPUFriend and CPUFriendFriend, with a base clock of 1.1 GHz and can boost all the way up to 4.7 GHz (idles at 800 MHz).

It is recommended to cap the TDP to 10W with VoltageShift as it tends to boost more than it should during idle loads, can help with temperatures and battery life.

GPU/Display

Getting the Intel UHD Graphics 630 took quite a bit of effort to work properly, It uses the natively supported device-id ig-platform-id, but required framebuffer patches in order for the internal display and HDMI over USB-C to function correctly. The 4K version of this laptop should work fine without further patches.

The internal display brightness controls worked out of box when using SSDT-PNLF-CFL.

SSD

The WDC PC SN520 NVME SSD worked out of the box without having to reformat with 4K sectors. Power management is working with NVMeFix.kext

Wifi and Bluetooth

Sadly the Intel AX200 is soldered to the motherboard, but does work thanks to the work of OpenIntelWireless, Wi-Fi and and Bluetooth work out of the box provided you use AirportItlwm.kext, IntelBluetoothFirmware.kext, and BlueToolFixup.kext

Sleep

Sleep works out of the box after mapping USB ports with USBMap.kext, disabling any unused ports/controllers.

Trackpad

Using VoodooI2C.kext and VoodooI2CHID.kext, the Trackpad works out of the box, including all gestures.

Sound

Sound works for the most part, but needs CodecCommander Install CodecCommander.kext into /OC/Kexts/ (if it does not already exist), then copy hda-verb to /usr/local/bin (Create the folder if it does not exist)

Combo Jack currently does not work (will be fixed sooner or later)

AppleALC might cause high kernel_task CPU usage for some people, it is under investigation. If you are encountering this issue, please disable AppleALC in your OpenCore config.

USB

USB works out of the box

Display Outs

USB-C to HDMI/DP works out of the box once GPU is properly patched

Thunderbolt

Currently does not work, the controller is most likely causing severe idle power drain but should be disabled as of 27a4fcb

Battery

Battery Capacity works when using proper SSDT hot-patching and SMCBatteryManager.kext

The battery drain should be fixed as of commit a6340b0

There is some drain compared to Windows/Linux, A non-working ACPI function GPE_L6F is eating CPU cycles for no reason, it can be easily fixed on linux with a one-line command echo "disable" > /sys/firmware/acpi/interrupts/gpe6F. It seems to be much more complicated on macOS, I tried using a ACPI hotpatch to rename _L6F to XXXX but it did not seem to have any effect on power usage.

A decent workaround for now is to try undervolting with VoltageShift

I use Power Manager to apply these offsets on boot and wake from sleep (these offsets may not work for every configuration, take caution and ymmv.)

voltageshift offset -100 -100 -100 -100 -100 -100 -100
