Introduction

---

NOTE - this repo is mainly for the T480s. I have another repo https://github.com/kk1987/P52s-hackintosh created for a P52s which might be a better reference for P52s/T580/T480 due to the hardware similarity (most notably T480s seems to use a different TrackPad/TrackPoint implementation.)

---

This repo is my notes and configuration files for my hackintosh (10.14-10.14.1 Mojave) installation on a Thinkpad T480s. It's originally posted at https://www.tonymacx86.com/threads/success-macos-10-14-on-thinkpad-t480s.261318/.

The Clover files in this repo (config.plist + ACPI/patched/ + kexts/Other/ + drivers64UEFI) in theory should boot macOS 10.14, installer or post-install, on any T480s. It may work on similar laptops like T480/T580/P52s too. There's absolutely zero guarantee though, since I never tested on a different machine. Verified working on my P52s.

For initial booting, it might be necessary to inject an invalid ig-platform-id like 0x12344321. Subsequent boots should be fine without.

Basic Info

Hardware (OEM):

• i5 8250U CPU, Intel UHD 620 (no dGPU)
• 1080p screen w/ touch (IVO R140NWF5 R6, w/ ELAN USB touchscreen built-in)
• Realtek ALC3287 ("ALC257")
• Intel Ethernet I219-V
• Synaptics TrackPoint + ELAN TrackPad
• Synaptics Fingerprint Reader

Hardware (upgraded/replaced):

• 24GB RAM (8G onboard + 16G SODIMM, DDR4)
• ADATA SX8200 960GB NVMe SSD
• BCM94352Z M.2 WiFi + BT (card is E-key while mobo slot is A-key; mechanically modified with knife/file to fit)

UEFI Settings:

• Current: UEFI Firmware version 1.26
  • "Thunderbolt BIOS Assist": disable (default) to make front type-C port work in macOS; enable to reduce idle power consumption in Linux
• Static / partial-hotpatch ACPI files before d6dd12a were patched against UEFI version 1.25, all ports/devices enabled (default), and "Thunderbolt BIOS Assist" enabled

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 (as mouse)
  • Ethernet, WiFi, Bluetooth
  • Screen brightness & brightness shortcut keys
  • Basic audio including speaker, internal mic, headphone jack
  • Touchscreen
  • Camera
  • Card reader
  • All USB ports
  • HDMI video port, with audio
  • USB type-C video output, with audio
  • Sleep/resume (takes 25-30s to sleep)
  • Thunderbolt (as long as you didn't enable "Thunderbolt BIOS Assist")

Limited functionality

• HID: No multi-touch/scrolling; both TrackPad and TrackPoint function as PS/2 mouse
  • Smart Scroll can be used to emulate mid-button TrackPoint scrolling (enable "Vector Scroll" with "Drag Button 3")
  • Alternatively, multi-touch trackpad can be enabled using patched ELAN driver found at https://github.com/linusyang92/macOS-ThinkPad-T480s (requires disabling TrackPoint in UEFI though)
• 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
  • DP/HDMI audio output via USB type-C: it works, but compatibility may be limited. I have an Apple type-C to HDMI adapter that works, and a StarTek type-C to DP cable that doesn't. Both work on a real MacBook, obviously
  • 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
• Display
  • HiDPI can be enabled using https://github.com/xzhih/one-key-hidpi but there will be the glitch-after-wake issue, which cannot be solved by the EDID patching provided by one-key-hidpi script (the patch sets panel depth as 8-bit and will cause a blank screen on boot on my FHD touch panel)

Not Working / Untested

• Fingerprint reader (no driver)
• BT Handover etc. (untested)

Clover UEFI Setup

Clover

• Verified working with sf.net versions r4658, r4674

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
• Current: "Full Hotpatch" configuration (most SSDTs taken from linusyang92's repo)
• Commit a95dec1: "Partial Hotpatch" configuration (patched DSDT & add-on SSDTs in ACPI/patched)
  • This likely won't work with different hardware specs, or even different UEFI versions/settings
  • See git changelog for details. (Mostly just FYI which patches are needed)
