This repository contains a sample configuration to run macOS (Currently Mojave 10.14) on a Lenovo ThinkPad T480s

Used Hardware Configuration

• Lenovo ThinkPad T480s
  • Intel i5-8250U
  • 8GB RAM onboard + Crucial DDR4 2400-SODIMM
  • Samsung 970 evo NVMe SSD
  • Dell DW1560 Wireless (original Intel AC8265 not working)
    • Wi-Fi device ID [14e4:43b1], shows as Apple Airport Extreme due to FakePCIID_Broadcom_WiFi.kext
    • Bluetooth device ID [0a5c:216f], chipset 20702A3 with firmware v14 c5882 using BrcmPatchRAM2.kext
  • Realtek ALC257 using VoodooHDA.kext temporarily, AppleALC.kext not working (though layout 11 codec is correct)
  • Intel UHD Graphics 620 (Nvidia MX150 disabled, Optimus not supported by macOS)
  • Power management and battery status by ACPI hotpatching
  • Integrated camera (works out of the box)
  • Keyboard/Elan Touchpad (PS/2) using ApplePS2SmartTouchPad.kext v4.7b5 by EMlyDinEsH
    • Support multi-touch gestures
    • Need to disable Trackpoint in BIOS (otherwise touchpad would be disconnected)

      Offset    Original  Patched
      0000ABF5  72        EB
      0000AC2D  01        04
      

• Disabled devices
  • WWAN (no module)
  • Trackpoint (can be enabled when using VoodooPS2Controller.kext)
• Untested devices
  • SD card reader
  • Fingerprint scanner
  • Thunderbolt 3 (USB type-c works)
• Firmware Revisions
  • BIOS version 1.25

Preparation

• (Important) Copy EFI/CLOVER/config.example.plist to config.plist. Edit SMBIOS entry in config.plist to work properly:
  • BoardSerialNumber: Change any Z to random letters or numbers
  • Memory -> Modules: Fill in the correct size for your RAM in Size, e.g. 4096 for 4GB, 8192 for 8GB
  • SerialNumber: Change any Z to random letters or numbers
  • SmUUID: Generate a unique UUID by uuidgen or simply using an online service
• All SSDT hotpatches are located at EFI/CLOVER/ACPI/dsl. You can update the compiled .aml binaries by running update.sh (macOS) or update.bat (Windows).
• The SSDT-KBD.aml is tuned for ApplePS2SmartTouchPad.kext. If you want to switch to VoodooPS2Controller.kext, use SSDT-KBD.aml in backup folder instead.
