Lenovo T460 macOS with Clover Guide
Latest Release on GitHub (July 2020)
Updated to Clover r5120
Updated Lilu based kexts - Lilu, ALC, WEG
Various Tweaks over Last months
The main branch in my github repo is a complete Clover ESP (/EFI) bundle and kext pack for the Lenovo T460. The current file bundle seems to work on Sierra, HighSierra, Mojave and Catalina. There is an OpenCore branch in the repo as an alternative to Clover. This guide was developed for a Clover implementation. But the thread has evolved to include discussion of both Clover and Opencore for these systems: T460 and T470 family of ThinkPads.
Full Clover file set - config.plist etc.
Includes all custom kexts
Includes custom DSDT/SSDT scripts and patches
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.

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.
New Installation - Steps and Details
Part 1 - OS Installation
Part 2- Post OS Installation and Setup
Notes on Custom Kexts
Hello everyone, i just want to ask something. why is it that my radeon hd 7770 graphic card was detected as "Latte" gpu instead of verde when using radeon_bios_decode? is the card actually a Latte graphic card but someone flashed it so they can sold to me as radeon hd 7770? or is it actually a real radeon hd 7770 but the tool falsely detected it as latte cpu?
I'm having a problem with BIOS. I hope someone can help me to fix it.
I was able to boot to Wins or Catalina with no issues with OC. When I tried to go to BIOS i got a black screen with white cursor, nothing else (you can see it on the video). I can move cursor until i click right/left button, it freeze.
After reboot i would boot to Wins/Catalina, no issue. My first guess was to reset CMOS by removing a battery. So i did it. And that was bad idea. After that i wasn't able to boot to any OS. I get that black screen because CMOS got reset. Probably there should be a screen with option to set time, date, etc, before you boot to OS. But, I dont see it. I tried to reset CMOS several times, removing the battery ot using a jumper. Nothing helped. I get the same result. I've noticed that resolution is much lower on my 27" screen (2K). Cursor can move to half of the screen, horizontally and vertically. So I started troubleshoot with other components.
1. I tried every RAM stick on each slot, same result. RAM works on another PC.
2. I tried to remove GPU and use iGPU (HDMI and DVI), same result.
3. I tried DP, HDMI, VGA with GPU, same result. (GPU works fine on another PC)
4. I tried to unplug everything, USB 2, USB 3, SSD's, same result.
The only thing i haven't tried yet is another power supply, just because i dont have one to test it.
Not sure what was the trigger because so far i was able to get to BIOS with no issue. The only thing that it comes to my mind is that a week ago I came across a software, Gigabyte EasyTune and I played with it. Ususallu, if I want to OC my CPU I do it from BIOS, never used any software. EasyTune did work and OC'ed my CPU and i rebooted my PC many times since then but i never tried to access BIOS until yesterday.
I hope you someone can give some tips of how to fix it. Not sure if BIOS got corrupted because of the software or not.
