Hello Everyone ,,
 
I'd  like to share with you my experience with Lenovo ThinkPad P50 ( EFI , and Installation Process with some tips ) Hopefully to be useful for anyone who own Lenovo ThinkPad P50 
 
Before start I want to show you my device specs , and I'm  sure 99% this will work too with any P50 have different spec. specially Intel i7 CPUs:
 
- Intel Xeon E-3 1535 v5 ( P530 Intel HD Graphics )
- 32 GB RAM
- 256 GB SK Hynix Nvme SSD pc401 hfs256gd9tng-62a0a - for Mac OS  ( be careful not all nvme ssd are compatible)
- 256 GB Samsung Evo 850 SSD - for Windows 
- 4K Screen 
- Nvidia Quadro M2000M 4 GB ( Useless - Disabled )
- Intel WiFi Card ( Should be change to a compatible Broadcom one )
 
BIOS SETUP :
 
I highly recommend this steps before going to BIOS SETUP according to my experience with this Laptop :
 
      *( Update your BIOS Firmware to the latest one using windows )
 
      *( Remove Battery , Open the back cover and unplug the small CMOS BATTERY for about  4~5 minutes and put everything back again )
 
       * ( Remove any SSD HDD Nvme disks , USB , DisplayPort , Dock .. etc during installation, keep only the target Disk )
 
-------------------------------------------
Now Power your PC and Press F1 to enter the BIOS SETUP
 
   - Reset BIOS to its defaults
   - Adjust Date and Time 
   - Config ----> Network ---> Wake Up on Lan ( AC Only )
                                                   Network Stack ( Disabled )
 
  - USB ----> USB UEFI support  ( Enabled)
 
  - Display ------> Total Graphic Memory (256 MB)
                               Graphic Device ( Hybrid)
 
  - RAID -----> Disabled
 
  - Security -----> Security Chip Selection ( Discrete TPM )
                               Secure BOOT ( Disabled )
                               Intel SGX Control ( Software Control )
 
  - Start Up ------>BOOT Priority order ( USB HDD - Mac OS Disk - Windows - and so on ....... with this order )
                               UEFI/Legacy ( UEFI Only )
                               CSM Support  ( NO )
----------------------------------------------------------------------------------------------------------------------------------
 
**   F1 to Enter Bios - F12 for Boot Menu
***   Delete the EFI Folder in your Installation USB and replace it with the Attached one 
****   Generate new serial for SMBIOS MacBook Pro 13.1
*****    If your CPU is XEON then go to Config.plist CPU Section and Add 0x05A5 under Type ( Fix for Unknown CPU )
****** You can delete boot-args "brcmfx=1 & brcmfx-driver=#a" if you want , I used it in my case with 1820A card to fix wifi issue
******    After you successfully installed OS , now Copy the same EFI Folder to your main EFI Boot Disk Partition 
*******    Now install all the attached KEXTS to "Library / Extensions"  using Hackintool.app or by any method and rebuild cache and repair permissions
********    Check and compare the KEXTS in Library/ Extensions and Delete the repeated ones from Clover / Kexts / Others ( Important don't duplicate the same kexts here and there )
 
FYI : LiluFriend.kext include ( Lilu , WhatEverGreen, AppleALC , AirportBrcmFixup ) All In One 
 
 
 
You are Done 
---------------------------------------------------------------------------------------------------------------------------------
 
What is working :
 
- 4K Intel HD P530 2048 MB

             See the Screen Shot 
 
Important Notice For Future OS Updates Installations : 
 
To avoid Kernel Panic during install any future updates process please remove ( FakeSMC.kext and LiluFriend.kext ) from Library/Extensions directory to Clover / Kexts / Others .
After update process finish put them back to Library/Extensions and delete them from clover . I hope this is clear enough
---------------------------------------------------------------------------------------------------------------------------------
 
Happy Hackintosh , Let me know if you have any issue or difficulties during installation or later , I will try to help you
 
*** Headphone Audio Distortions Fix ***
 
- just in case having this issue with headphones , go to clover >  Devices > Properties > and change Audio Layout Id from 03000000 to 16000000 this means ( from Layout ID  3 to Layout ID 22 )
 
if this is not enough then place Codeccommander.kext in Library/ Extensions or Clover / kexts / other
And place hda-verb and Jack fix to usr/bin folder
In Catalina use this command to enable disk read and write ( sudo mount -uw / ) and show hidden files to see usr/ bin folder and place fixes there... audio will be fixed successfully

Lenovo T460 macOS with Clover Guide
Latest Release on GitHub (November 2019) Updated to Clover r5099 Updated Lilu based kexts - Lilu, ALC, WEG Added acidanthera VoodooPS2 kext v2.0.4 moved the older 1.9 to the Misc Folder as an option.
  Various Tweaks over Last months The zip file is a complete Clover ESP (/EFI) bundle and kext pack for the Lenovo T460. The current file bundle is tested on Sierra. 
Note: I never got the GFX fully working on El Capitan. 
Full Clover file set - config.plist etc. Includes all custom kexts Includes custom DSDT/SSDT scripts and patches Utility scripts The zip bundles are posted to GitHub: https://github.com/tluck/Lenovo-T460-Clover/releases
Caveat: The T460 systems used here was configured with: i5-6300U, Intel HD Graphics 520, 1920x1080 touch screen. If you have a different system model, then extract the ACPI files and use the included scripts to create a set of files consistent with your system type and BIOS version. See below for details.
Credits: RehabMan, Shmilee, vusun123, TimeWalker, Mieze from which, much of their work and help is/was was used to get the T460 to this point.
Devices and aspects working:
Ethernet -  Intel I219LM is enabled via IntelMausiEthernext.kext WiFi/BT - substitute the Intel WiFi/BT with a compatible Broadcom or Atheros chip Audio - ALC293 codec implemented via AppleALC.kext (the old AppleHDA_ALC293 and CodecCommander kexts are not needed) PS2 - ClickPad + TrackPoint + all 3 buttons - using a modified VoodooPS2Controller to support new layouts - and added some custom Fn key maps based on 440/450 dsdt USB - implemented via custom SSDT + USBInjectAll kext. All USB3/USB2 ports are intel-based and work -  3 external USB and internal Camera, BT, etc  Sleep/Wake - the sleepwatcher package and custom sleep/wake scripts are used to help with sleep/wake for BT and PS2 devices. Note: have not tried to implement the SD card reader - no driver found.

Notes on Custom Kexts
 

Gigabyte, in their infinite wisdom, decided to remove the option to disable serial ports, and not being able to do so has been causing me some problems. I know that I have to either use a patch in clover, or create a custom SSDT to disable super I/O, but I honestly do not know how to go about doing this. One of the weirder problems I'm experiencing is the inability to connect to Apple Music (error 11556) unless I go into my network settings, and delete my serial connection. If anyone could help me out with this, that'd be greatly appreciated; anyway, thank you for taking the time to read this.
