Thinkpad-X1-extreme-EFI: An Objective-C repository from kfc2008520

update log

[19-5-29] add noTouchId.kext. MacOS is expecting Touch ID to be available, causing lag on password prompts, this kext can fix this.

The part that can work

Sound card (AppleALC)
intel cable Gigabit LAN (mini RJ45)
intel integrated graphics
nvidia graphics card (screened off, power saving, although the dual graphics card is no problem, but mojave no nvidia graphics driver)
Battery level display (DSDT patch, you can use RehabMan/thinkpad x230i patch directly)
Machine sleep
usb port configuration
Touchpad and touch screen (multi-finger touch is not yet completed)
Keyboard function keys, volume and screen brightness (DSDT EC _Q14, _Q15 patch)
card reader
Wireless network card and Bluetooth (requires adapter board to connect with smart card, solution from @Errrneist)
intel bluetooth worked (Thanks for IntelBluetoothFirmware)

Use intel original card Bluetooth

By default, the USB port of the Bluetooth original card is blocked. If you need to use the original Intel network card, modify config.plist yourself to remove the shield of HS14.

<dict>
   <key>Arguments</key>
   <!-- Remove the shield of HS14 -->
   <string>-lilubetaall -cdfon uia_exclude=HS14,HS05,HS06,USR1,USR2</string>
         ...
</dict>

Installation Precautions

This EFI supports installation when using it, without the need for a separate config.plist.

HDMI

HDMI video output (requires usb 3.0 external graphics card supporting displaylink chip, the solution comes from @Errrneist)

Wireless network card perfect custom plan

ALCPlugFix

You may need to install the daemon process under ALCPlugFix/alc_fix (my modified version for X1E series) to solve the problem of popping the headphone jack.
