Introduction

This repo is my notes and configuration files for my hackintosh (10.14-10.14.1 Mojave) installation on a Thinkpad P52s. The Clover files in this repo (config.plist + ACPI/patched/ + kexts/Other/ + drivers64UEFI) in theory (I didn't test extensively) should boot macOS 10.14, installer or post-install, on any P52s. It's highly likely to work on a T580 or T480, too.

For T480s, see https://github.com/kk1987/T480s-hackintosh, of which this repo was initially based off.

The configuration here is tailored for my P52s which has a 4k UHD display. For a different screen configuration, it might be necessary to first boot without QE/CI by injecting an invalid ig-platform-id like 0x12344321, then fix the IGPU & EDID configurations accordingly.

(Hint: refer also to the T480s repo, which is for a FHD touch screen, and might also work with FHD and 1440p non-touch screens. Differences include which ig-platform-id/device-id to inject in config.plist/Devices/Properties, and whether EDID injection is required.)

Basic Info

Hardware:

• OEM
  • i7 8650U CPU w/ Intel UHD 620
  • Nvidia Quadro P500 dGPU
  • 4k screen (BOE NV156QUM-N44, matte non-touch)
  • Realtek ALC3287 ("ALC257")
  • Intel Ethernet I219-LM
  • Synaptics TrackPoint & TrackPad
  • Synaptics Fingerprint Reader + IR Camera
• Upgraded/replaced
  • 32GB RAM (16G DDR4-2400 x2)
  • ADATA SX8200 960GB NVMe SSD
  • BCM94352Z M.2 WiFi + BT

UEFI Settings:

• UEFI Firmware version 1.16
• "Thunderbolt BIOS Assist": disable (default) to make front type-C port work in macOS; enable to reduce idle power consumption in Linux

Partitioning & other OSes:

I did a tri-boot setup with installation order as follows:

• macOS -> Windows 10 -> Arch Linux (Antergos)

Status

Working

• most features do work
  • Keyboard & TrackPoint/TrackPad
  • Ethernet, WiFi, Bluetooth
  • Screen brightness & brightness shortcut keys
  • Basic audio including speaker, internal mic, headphone jack
  • Camera
  • Card reader
  • All USB ports
  • USB type-C video output
  • Thunderbolt (as long as you didn't enable "Thunderbolt BIOS Assist")

Limited functionality

• Audio
  • (I don't see why it's ever needed but) there's no external mic support
  • "out of the box" headphone sound may be glitchy. Disabling "Use ambient noise reduction" in Settings -> Sound -> Input seems to fix this
  • Alternatively, VoodooHDA can be used. It supports enternal mic via combo jack (without auto-switching) but doesn't support HDMI audio. Configuration in Info.plist need to be updated with iGain=0, PCM=100, Rec=50
• HDMI/DP output
  • DP/HDMI via USB type-C: video works fine. Audio device shows up but no sound is transmitted
  • Standalone HDMI port: 50/50. With my limited testing, video output works with a 1440p monitor but not with a 4k one. Also when connected, no audio device shows up
• TrackPad: works but isn't perfect
  • No 3- or 4-finger gestures
  • 2-finger-tap right click doesn't work 99% of the time (2-finger-click works fine)
  • Scrolling can feel sluggish
  • Could be disabled by PrtSc key. (It won't disable TrackPoint, which mostly works fine)
• Sleep/wake
  • (Most of the time) Power LED continues to blink after wake
  • (In rare cases) Bluetooth may become unavailable after wake

Not Working / Untested

• Sleep/wake
• NVIDIA P500 GPU (no way to utilize, disabled via SSDT)
• IR Camera (no way to use in macOS / breaks FaceTime; disabled)
• Fingerprint reader (no driver / no way to use)

Clover UEFI Setup

Clover

• Verified working with sf.net versions r4674, r4700

drivers64UEFI

• ApfsDriverLoader-64
• NvmExpressDxe-64
• AptioMemoryFix-64 (or OsxAptioFixDrv-64 + EmuVariableUefi-64)

config.plist

• (archived in this repo)

kexts

I put all extra kexts under EFI/CLOVER/kexts/Other.

• FakeSMC (w/ all plugins), for Hackintosh to boot
• ACPIBatteryManager, for battery status
• AppleBacklightFixup, for brightness
• AppleALC + CodecCommander, for audio
• Lilu, for various stuff below to work
• WhateverGreen, for iGPU
  • See Devices/Properties patches in config.plist (set ig-platform-id & device-id + patch for 32MB DVMT-prealloc)
• USBInjectAll, for USB ports
  • Touchscreen, Bluetooth etc. won't work without this
  • See SSDT-UIAC.dsl for machine-specific patch
• VoodooPS2Controller, for keyboard/touchpad/trackpad
• IntelMausiEthernet, for Ethernet
• AirportBrcmFixup, for WiFi; BrcmFirmwareData + BrcmPatchRAM2, for Bluetooth
  • Refer to toledo's guide

ACPI Patching

• Based on RehabMan's guide and linusyang92's T480s repo
