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
• 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:

1. Ethernet -  Intel I219LM is enabled via IntelMausiEthernext.kext
2. WiFi/BT - substitute the Intel WiFi/BT with a compatible Broadcom or Atheros chip
3. Audio - ALC293 codec implemented via AppleALC.kext (the old AppleHDA_ALC293 and CodecCommander kexts are not needed)
4. 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
5. USB - implemented via custom SSDT + USBInjectAll kext. All USB3/USB2 ports are intel-based and work -  3 external USB and internal Camera, BT, etc 
6. 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.

ACPI Files

 

 

If you have a T460, the ACPI files in zip should just "work" - at least to get the macOS installed. But in general it is best to make your own custom DSDT based on your system BIOS.  The ACPI (DSDT/SSDT) modifications are handled by combination of Clover on-the-fly patches, custom/direct patches to DSDT and the "hot-patch" method. Here are the key files:

• DSDT- patched DSDT with included scripts. 
• ssdt - (not included) and can be created for your CPU - will define C/P states via Pike's script ssdtPRGen.sh
• SSDT-CPU - generic - for HWP support -  (no longer needed)  Clover 4016+ will generate SSDT with HWPEnabled and PStates true
   
• SSDT-ARPT-T460 - Airport for Broadcom 4360 (if added)
• SSDT-HACK-T460 - add misc functions for DSDT
• SSDT-HDEF-T460 - fix/define Audio for ALC293 codec with layout ID 28 - linked to AppleALC.kext (or optional AppleHDA_ALC293.kext)
• SSDT-IGPU-T460 - fix/define GFX for Intel HD 520 device 1916 (not really needed - since we inject graphics via clover as 4063)
• SSDT-LPC-T460 - add/fix/define LPC device
• SSDT-PNLF-T460 - add LCD/Panel
• SSDT-PS2K-T460 - fix/define/add T460 defines keyboard and ClickPad/TrackPoint - linked to VoodooPS2Controller.kext
• SSDT-SMBUS-T460 - add/fix/define SMBUS device
• SDT-XHC-T460 - fix/define/add internal and external USB ports by custom UIAC device - linked to USBInjectAll.kext
• SSDT-XOSI - generic - to set OS type

 

The (sample) custom DSDT in the zip is extracted from a T460 on BIOS v1.22.  

In the DSDT.T460 directory, there are the samples and scripts to create your own custom DSDT. The DSDT in the zip may work but its best to just match your system. The create_patch_DSDT.bash script will create a patched DSDT starting from the original ACPI files located the ACPI-Tables folder. The final DSDT is patched via patchmatic using the files in patch-files folder.  Follow these steps:

 

1. Download and expand (extract) the contents from the Latest Release (zip file). 
    
2. Copy the Utilities files into /usr/local/bin  The key files needed here are patchmatic, iasl, and espmount.bash
   Note: I assume the directory /usr/local/bin exists and is in your environment variable PATH

   
   cd ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/Utilities/
   sudo ./install_tools.command

3. Extract ACPI files.
   Start by extracting your original ACPI files by hitting F4 after you boot up with Clover. It will save the files to EFI/CLOVER/ACPI/origin. Note: this origin folder needs to exist.
    
4. Copy the newly created ACPI files from the HD ESP to your working folder
   Copy the original .aml files from the origin directory - just the ones with names starting with DSDT and SSDT - from the ESP to a directory called DSDT.T460/ACPI-Tables ( which is part of the expanded zip file).
   
   Note: To mount the main system ESP, run this command which was installed with the tools in step 1.

   
   /usr/local/bin/espmount.bash 0

5. Create your own patched DSDT.
   Using the original copied to the ACPI-Tables directory as the source, create a custom patched DSDT.dsl by:

   
   cd ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/DSDT.T460
   ./create_patched_DSDT.command

6. Install the new custom ACPI files into the ESP
   Now there is a new custom DSDT.dsl along with some other .dsl files in this same directory as the result of the patching script. To compile and install this newly create patched DSDT.dsl along with the other SSDT*.dsl files into the ESP, run this script below. It will mount the system disk partition disk0s1 (the ESP) on /Volumes/ESP, compile all the *.dsl files, and then copy them all to /Volumes/ESP/EFI/CLOVER/ACPI/patched location

   
   ./install_ACPI_to_ESP.command

 

New Installation - Steps and Details

 

BIOS settings:

• Update to latest BIOS
• Use Defaults settings, but check these items:
• Set Security / Memory Protection / Execution Prevention = Enabled
• Disable Secure Boot

Terms:

GPT = GUID Partition Table
MBR = Master Boot Record
ESP = EFI System Partition

The ESP is created automatically as the first (hidden) partition by the Disk Utility when the GPT option is selected for partitioning a disk.

Part 1 - OS Installation

 

 

 
This procedure is for a new macOS installation using a USB Installer. If you are upgrading from an older working version of OS X (say El Capitan) already on your HD, skip down to Part 2, Step 3 to update your ESP. You must replace or merge in the changes from the EFI/CLOVER files to your HD ESP before you perform the upgrade. 

1. Download and expand (extract) the zip file contents from the GitHub Lenovo T460 Clover Latest Release.
   This same file set will be installed on the USB and the HD for UEFI boot.
    
2. Download macOS from the App Store - they are freely available
   We build a macOS USB installer with the standard macOS installer app downloaded from the "App Store".
    
3. Install macOS to a GPT formatted disk using the standard Install macOS.app downloaded from the Apple Store.

Create macOS USB installer

1. Partition an 8GB (or larger) USB formatted with GUID Partition Table (GPT)
   - In Sierra, use the Erase option to change from MBR to GPT/GUID scheme.
   - Name the new partition USB. The install process will rename it, but this matches the script below.
   - Use format: macOS Extended (Journaled)
   Note: if you have a larger USB (say 16GB) you can split into 2 8GB partitions, so you can have 10.12 and 10.11 installers on the same USB key 
    
2. Run this command to copy the downloaded bits to the USB key: 

   
   sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ Sierra.app --nointeraction

Put Clover installation on USB

1. Install Clover on the USB
   a ) Manually mount the ESP of the USB and copy the entire EFI directory.
   b ) If not done already, expand the downloaded Zip to ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD (this set is called the Zip below)
   c ) Copy the EFI directory to the ESP directory of the USB
   

   For example, assuming the USB is disk1:

   
   sudo mkdir /Volumes/ESP-USB
   sudo mount -t msdos /dev/disk1s1       /Volumes/ESP-USB
   cp -a ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/EFI/ /Volumes/ESP-USB/EFI

   Note: run "diskutil list" on the command line to find your USB and HD disk devices
 
   
   Dual BOOT tip:
   If you plan to dual boot Windows from the same HD - DO NOT make the 2nd partition NTFS or ExFAT with the Disk Utility app.
   Make them both macOS Extended (Journaled) to keep a PMBR vs MBR.
   Size the 2 partitions appropriately - but later you will delete/reformat the 2nd partition for Windows. I recommend gpt which can make an NTFS partition without converting the PBMR.
        
2. For a T560: Set up the ACPI configuration files to match your model.  
   
   go to /Volumes/ESP-USB/EFI/CLOVER
   Rename  ACPI to ACPI.T460
   Rename ACPI.T560 to ACPI

Boot Clover from USB Installer and select Install macOS

1. Boot from the USB and install macOS on your GPT disk partition. (Hit F12 to select USB drive)
   
   Make sure the HD/SSD drive is formatted using:
       Scheme: GUID Partition Map (GPT),
       Partition Name: macOS,
       Format: mac OS Extended (Journaled)
   
   Note: *should NOT be needed* but If you get a KP from AppleIntelSKLGraphicsFramebuffer, then use the Clover Options Menu and to select the alternate configuration file: config.noSKL.plist. This injects a bogus graphics device ID 0x12345678.
    
2. Click through GUI Install menus and wait for the installation to fully complete - on a spinning disk takes about 30-45 minutes. Follow these Notes and Tips
   • When the installer screens shows:   "To pair a Bluetooth keyboard, turn it on and wait for your computer to connect to it.”

  
              Hit the Space Bar to get past this step
   • When installer seems to hang at:  "About a second remaining”
              

Don’t Panic, this "second" may take about 10 minutes or more to finish.
              Just wait for the installer to reboot the computer and continue the installation.
              The whole install process takes  about 1 hour to complete.
   • On the first boot from the HD when asked:  "How Do You Connect?”
              

Select: “My computer does not connect to the Internet”
              And set up the network later after installation the NIC driver kext.
              Your Intel WiFi will not work. Period. 

 

Part 2- Post OS Installation and Setup

 

1. Boot Clover from the USB 
   On startup, hit F12 and select USB -  You boot Clover from the USB, but now select the newly installed disk/partition to start macOS.  
   
   Note: *should NOT be needed* but if you get a KP from AppleIntelSKLGraphicsFramebuffer, then use the Clover Options Menu and select config.noSKL.plist. See step 7 below to fix this problem. AppleALC.kext + Lilu.kext will patch the Graphics Framebuffer to avoid a DVMT check KP.
   
   Note: You may see 3 Volumes instead of the expected 2 on the HD - macOS + Recovery HD - make sure you pick the volume that is NOT labelled Recovery HD. See step 3 below to convert the logical volume which will eliminate the abstraction and confusion.
    
2. Complete the installation steps and login
   Note: This will boot up macOS with Clover injecting the custom kexts from the USB (for now). 
    

3. Convert the Logical volume to Physical volume (for HFS)

   With an HFS formatted volume, the full installer may want to make a logical volume. So for simplicity, I recommend one to revert the root volumes to a regular volume.
   
   In Terminal run: 

   
   sudo diskutil corestorage revert /

4. Install Clover (ESP) on the HD
   Now the make the HD bootable with Clover. Transfer the Zip file contents to the new HD. Then use a similar process as used for the USB.  
   Note: I assume the Zip is in ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/
   
   a ) NVRAM
   Since we are using Clover's EmuVariable method to simulate NVRAM, Clover looks for the file nvram.plist to get its persistent values - which is stored in the ESP now. Install the "root" utilities and clover scripts and files from Utilities folder to your HD. This step is important as it installs the "rc scripts" to save the nvram contents to a file upon reboot.
   
   Important: It will register your system to use a LogoutHook.

   
   cd ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/Utilities/
   sudo ./install_clover_scripts.command

   b ) ESP
   The ESP contents on the HD are now to be made exactly like the ESP used for the USB installer above.  
   Mount the HD ESP and copy over the EFI items. You can follow the same procedure used for the USB installer.
   Note: If you previously installed Windows, be careful to not lose the EFI/Microsoft contents by following the procedure outlined below. 
   
   For example, assuming the main drive is disk0:

   
   sudo mkdir /Volumes/ESP
   sudo mount -t msdos /dev/disk0s1       /Volumes/ESP
   cp -a ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/EFI/ /Volumes/ESP/EFI

   c ) Custom DSDT
   Using the procedure outlined above in the ACPI Files section, create and replace the custom DSDT in EFI/CLOVER/ACPI/patched
    
5. Install Kexts onto the HD in /Library/Extensions
   
   a ) For 10.12.4+: Create a custom AppleBackLightInjector kext

   Note: This kext is not needed on the USB installer.
   
   Since this method replaces the IntelBacklight.kext (which is still included as an optional kext) - manually remove that kext if present. Now create a custom Backlight Injector that matches your LCD Panel. The script will update the kext in the ../../EFI/CLOVER/kexts/Other directory - which is the unzipped package location. Run this procedure script:

   
   cd ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/Utilities/Create_AppleBacklightInjector_kext/
   sudo ./createAppleBacklightInjector.command

   b )  Install the kexts
   Install the custom kexts from the Zip kexts directory to the /Library/Extensions directory by running:

   
   cd ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/EFI/CLOVER/kexts/
   ./_kext-install.command

6. Ethernet Device Installation (Optional)
   This step loads the ethernet kext and resets network device order to have ethernet as en0 (seems to help with AppStore and iMessage etc)

   Note:  macOS may already have configured the ethernet, so this step may be unnecessary but it will not hurt anything either for a fresh installation.
   Run this set of commands:

   
   sudo kextload /Library/Extensions/IntelMausiEthernet.kext
   sleep 10
   sudo rm       /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

7. Remove the USB and Reboot with Clover from the HD
   
   Note: For this boot session, you may want to
   1- in Clover hit F3 to save the ACPI files
   and 
   2 - in Clover hit the spacebar on your boot volume selection (macOS) to set verbose mode to watch for any issues.

Notes on Custom Kexts

 

All the kexts listed below are contained in the zip file. The origin is listed below if you wish to download them as well. I recommend you use the _kext-install.command script to properly copy all kexts to the /Library/Extensions directory.
 

• Audio/GFX: AppleALC.kext  + Lilu.kext  kernel patcher
  - 2 layout options
  - If you have a Docking Station, you can use LayoutID 28 for HDMI, Speaker, Mic, Headphones, ExtMic + extra LineOut for Dock Out
  - or optionally use LayoutID 29 to remove the extra LineOut option if it is not wanted.
  
  Important:
  1. Requires matching SSDT-HDEF with layoutID=28 or 29. The AppleALC kext defines the patches for AppleHDA and AppleIntelSKLGraphicsFramebuffer.kex in lieu of Clover. This kext version has extra GFX Framebuffer patching for DVMT KP,  brightness levels, as compared to the AppleALC distribution on GitHub.
  
  2. Keep original/unmodified AppleHDA.kext in /S/L/E and add the AppleALC.kext and Lilu.kext to /Library/Extensions for full audio support (and critical patching)

Obsolete: Also included are the old alternate audio kexts in ALC293 directory: 
- AppleHDA_ALC293.kext (v9278.56) -  custom kext adapted from an ALC292.kext and based on 10.12.3 AppleHDA. This kext requires the HDA kext patching via Clover.
- CodecCommander_ALC293.kext  - TimeWalker's kext - with ALC293 added - OPTIONAL - used to resolve missing input/outputs or sleep/wake issues.
 

• Old Keyboard/Mouse: VoodooPS2Controller.kext (v1.9.2) - RehabMans's PS2 Keyboard/TouchPad/TrackPoint (my branch has been merged in to master branch)
  • This version has T460 definitions in the SSDT-PS2K 
    see LENOVO T460 "override" settings. Change defaults to suite your needs.
  • VoodooPS2Controller keyboard mappings have 3 or 4 finger swipe left/right to back/forward configured for Safari browser
  • Note: If MouseMiddleScroll is set to true - TrackPoint scrolling with MiddleButton works better. 
     
• OS: FakeSMC.kext (v6.26.1443) - Core hack mechanism. Using Kozlek's version + plugins + custom FakeSMC Info.plist
  - A Custom package is included in the Utilities folder so you can install HWMonitor.app - it just selects these 2 Plugins Sensors: ACPI and CPU.
  - Two Custom SMC keys are added to Kozlec's standard FakeSMC - FNum (to find the Fan) and ACID (for AC power and eliminate powerd syslog messages every 30 seconds).
   
• Battery: ACPIBatteryManager.kext (v1.90.1) - RehabMan's kext to show/track battery info on menu bar
   
• GFX/LCD: WEG (and optionally) AppleBackLightInjector.kext (v0.9.3) - Whatevergreen (WEG)+ Lilu is the way to go now. But still can use RehabMan's Injector method - modified for Lenovo T460 to incrementally scale brightness in 17 levels from 0 to 1000 - see matching kext patch for Framebuffer brightness - which changes the maximum backlight brightness level to 1000. Note: The template file has 2 models: T420 and T460 but can be expanded as needed. To create a customer Injector, run the Utilities createAppleBacklightInjector script to create a custom Panel definition specific to your LCD. It will put the new injector in the kexts/Other folder. Install it along other kexts with _kext_install.bash script.

  
  cd ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/Utilities/Create_AppleBacklightInjector_kext
  sudo ./createAppleBacklightInjector.command

 

• Ethernet: IntelMausiEthernet.kext (v.2.5.0) - Mieze's kext for Intel LAN that supports TSO, EEE and other features. 
   
• USB: USBInjectAll.kext (v0.6.5) - RehabMan's kext -  See SSDT-XHC.dsl for related UIAC Device
   
• CPU: X86PlatformPluginInjector.kext (v9.9.9) - based on syscl's injector for HWP properties. When using, MBP13,1 there is a custom property file for standard T460 CPUs:  i7-6600U 3400 MHz, i5-6300U 3000 Mhz, i5-6200U 2800 Mhz and i3-6100U 2300 Mhz.  This is the only kext that must be in /L/E since it uses a symbolic link to the standard version of this kext.

WiFi Replacement

These kexts and procedure are used with Broadcom WiFi/B. Replace the Intel WiFi with suitable supported card such as a BCM94352Z (Dell DW1560) with proper M.2 form-factor. To install the SleepWatcher scripts, which will help with WiFi on Sleep/Wake use this process to install the scripts into / of your HD

cd ~/Downloads/Lenovo-T460-Clover-YYYY.MM.DD/Utilities/
sudo ./install_sleepwatcher.command

Reboot and check that SleepWatcher is running via "ps -ef | grep sleep".

On the graphics, I don't think the DVMT is the problem, as most Skylake laptops with closed-off bios such as Dell and Acer also have 32MB DVMT-pre allocated memory and they still boot in just fine - only minor glitch on finder bar and gradient area, but that can be dealt with by using other display color profiles

[vusun123]

First off, EDID. Use MonInfo ( Windows ) and post the current EDID of your monitor ( in text format, save the raw numbers ). Then we will actually have something to work with. There are also cases of laptop display ( mainly Sony Vaio ) doesn't detect the right EDID, therefore it will get stuck or black screen with backlight on

[vusun123]

OK nothing new here. Did you try manually injecting EDID into your DSDT ? Also put it in your config.plist for making sure it will always get injected

Hello,

 

Can you upgrade your guide with what is working or not?

 

Thank you

[vusun123]

Hello,

 

Can you upgrade your guide with what is working or not?

 

Thank you

Everything will work except for:

1. Stock Intel Wireless Card ( replace with a BCM4352Z or Dell Wireless 1830A ( BCM4360Z )

2. Graphics ( currently bugged )

[tluck]

@azerty076 - just posted a reply on another site. but i will update the GUIDE with my latest files etc. 

 

So quickly what works:

1) ethernet - IntelMausi kext
2) WiFi/BT - with BCM4352Z NGFF M.2 (aka Dell DW1560) - BrcmPatchRAM2 modified for to slow down firmware for USB wake.
3) Audio - ALC293 AppleHDA.kext
4) PS2 - Clickpad/Trackpad + TrackPoint + all 3 buttons - VoodooPS2Controller modified - F key maps
5) USB - custom SSDT + USBInjectAll kext mods. so all external USB3/USB2 ports and internal ports - Camera, BT work.
6) sleep/wake
 

have not messed with SD Card.

Hello,

 

I saw your message on the other site. It will be good if you can update this guide with the latest files  

 

Otherwise, I think that i saw in the bios that we can configure the NVRAM size, for me it was 128Mo I think. I have a core i7 6660U.

[aleixsr]

I posted the current/updated zip - not much changed. 

 

@tluck,

hello In my case I have 3D acceleration but I have transparency glitches only. I didn't rename file AppleIntelSKLGraphics.kext and my Hackintosh is working like a charm.

 

 

Here I attach transparency glitch example:

 

 

 

do you have this issue also ?

[tluck]

@aleixsr - what is your machine model? perhaps post your clover ESP and any other ideas for comparison? i will repost my zip later today. i made some slight changes in the VoodooPS2Controller kext.

[aleixsr]

It is exact the same as yours.

Here I attach my CLOVER folder in EFI partition, I think it is what you need.

Try changing display color profile. One of the sRGB profiles will solve the issue

[aleixsr]

darn. no joy. i tried your clover zip and got to same exact place - hung on IntelAccelerator.

 

wonder about differences in computer

cpu  - mine is i5-6300U? vs you have i5-6200U.

LCD - do you have touch screen?

 

i noticed you dont have a DSDT or SSDT files in your ACPI folders?

Try changing display color profile. One of the sRGB profiles will solve the issue

 

GREAAAATTTT !!!!!

 

It's true! Using sRGB IEC61966-2.1 Display profile did the trick!!

 

Thank you very much!!!

In fact your problem is the same as Haswell's 9MB Cursor issue. A little bit edit to the framebuffer will solve this matter without changing display profile, but I'm no expert on this one

[aleixsr]

Sorry, you're completely right, I don't understand what happened when I compressed files.

 

Here is the correct version, you'll fine references to your nickname

 

 

CLOVER.zip

[aleixsr]

cool. i'll test this out later. as i said i wanted to replicate your setup to see what is different on my box.

 

is your LCD touch?

 

No, my LCD isn't touch.

[aleixsr]

In fact your problem is the same as Haswell's 9MB Cursor issue. A little bit edit to the framebuffer will solve this matter without changing display profile, but I'm no expert on this one

 

Hi, it is not fully fixed, can you help me or tell me where I can found info about how to solve it ?

 

Thank you

[vusun123]

Thank you

Google "Haswell 9MB Cursor Patch" and 1st result should be from tony's site. It has basic information on how to fix that problem on Haswell, take that and do what you can with Skylake ( do not replicate the same patch onto the SKLFramebuffer, I do not know if the patch will crash your system or not )

[vusun123]

well - still no luck here on full 3D gfx - i took your zip and booted up - but again IntelAcellerator hangs.

seems the touch display is the difference.

Is your touch display PS2-based or I2C based ?

[aleixsr]

In fact your problem is the same as Haswell's 9MB Cursor issue. A little bit edit to the framebuffer will solve this matter without changing display profile, but I'm no expert on this one

 

Hello, I discovered that if I boot Windows and then reboot these graphic glitches don't appear, it is related to framebuffer? How can I know what I must change?

Here I attach ioreg files booting directly to OS X and rebooting from Windows.

 

Thank you very much

Can you please help me on how to edit framebuffer ?

 

thank you.

thank you.

As I said I'm no expert on binary patching, so I can't help you with this

[azerty076]

Can you please help me on how to edit framebuffer ?

 

thank you.

 

Maybe on the other site with rehabman's help...you should try.

Lenovo T460 Clover Guide

 

Overview - Work in Progress - 05-Oct-2016

 

• Updated Clover to 3787
• Updated VoodooPS2Controller.kext (again) 
• Updated FakeSMC kext to next rev

Attached is a current zip file with a complete /EFI pack for the Lenovo T460 using Clover on OS X

The current File Bundle is for 10.11 - the zip file attached to the bottom of this post

• Full Clover file set - config.plist etc.
• Includes all custom kexts
• Includes custom DSDT/SSDT scripts and patches

Caveat:

My system is a T460 with Intel 520 Graphics. Currently, the full advanced graphics are not working due to lack of DVMT pre-allocated memory. Most systems need 64, 96 or 128 MB. This system seems to have 32 MB. 

I must rename /S/L/E/AppleIntelSLKGraphics.kext to not be used at this time.

 

Credits to: RehabMan and Shmilee (more to come) from which, much is/was based on to get the T460 to this point.

 

 

Devices and aspects working:

1. Ethernet -  needs IntelMausiEthernext.kext
2. WiFi/BT - substituted Intel WiFi/BT with Dell 1510 (BCM43252Z) - BrcmPatchRAM2 modified for to slow down firmware for USB wake.
3. Audio - ALC293 AppleHDA.kext
4. PS2 - Clickpad/Trackpad + TrackPoint + all 3 buttons - VoodooPS2Controller modified - F key maps
5. USB - custom SSDT + USBInjectAll kext mods. so all external USB3/USB2 ports and internal ports - Camera, BT work.
6. Sleep/Wake - sleep watch
7. GFX 2D - turn off IntelAccellerator.

Note: have not tried to implement the SD card reader.

 

 

ACPI Patches and Files:

• DSDT.dsl - patched DSDT  
• ssdt.dsl - define C/P state for I5 via Pike's script

   

• SSDT-HACK-T460.dsl - add misc functions
• SSDT-XOSI.dsl  - sets OS type
• SSDT-LPC-T460.dsl - add/fix/define LPC device
• SSDT-SMBUS-T460.dsl - add/fix/define SMBUS device
• SSDT-HDEF-T460.dsl - fix/define Audio for ALC293 codec
• SSDT-IGPU-T460.dsl - fix/define GFX for Intel HD 520 device 1916
• SSDT-PNLF-T460.dsl - add LCD/Panel
• SSDT-PS2K-T460.dsl - fix/define/add T460 keyboard
• SSDT-XHC-T460.dsl - fix/define/add internal and external USB ports 

 

Boot Clover and define gfx device ID=0x12345678 until able to disable AppleIntelSKLGraphics.kext

 

Part 1 - OS Installation

 

see http://www.insanelymac.com/forum/topic/285678-lenovo-thinkpad-t420-with-uefi-only/page-25?do=findComment&comment=1952283

 

Part 2 - Post OS Installation and Setup on HD

 

 

1. Boot Clover from USB 

   On startup, hit F12 and select USB boot -  but now in Clover select the newly installed disk/partition to start OS X.  

    

   Note: You may see 3 Volumes instead of the expected 2 on the HD - OS X + Recovery HD - make sure you pick the volume that is NOT labelled Recovery HD. See step 3 below to remove the logical volume eliminates the confusion.

    

2. Complete the installation steps and login

   Note: This will boot up OS X with Clover injecting the custom kexts from the USB (for now). 

    

3. Convert the Logical volume to Physical volume

   The full installer likes to make a logical volume. So for simplicity, I recommend one to revert the root volumes to a regular volume.

    

   Run: 

   sudo diskutil corestorage revert /

4. Install Clover on the HD

   Transfer the Zip file and the most Clover installation pkg to HD (via another USB). 

    

   a ) Run the Clover_v2.3k_rxxxx.pkg to install the related latest bits into the HD OS and ESP (usually partition 1) of disk0. Use the link to download the pkg from SourceForge.  You can do this step later on if you don't have way to get it before you are setup on the network.

    

   Select (check box) at least first 2 items! This picture shows a good set of overall options:

   clover-pkg-options.png  After you close the pkg installer, then follow these step to replace the ESP.

    

   b ) The ESP contents on the HD are now to be made exactly like the ESP used to setup the USB installer above. If the ESP is not mounted from the running Clover installer pkg, manually mount the ESP of your HD on /Volumes/ESP. (See first 2 commands below.) Then you will replace the ESP installed by Clover in the previous step. Which means you copy/replace these 2 directories /Volume/ESP/EFI/CLOVER and BOOT with the ones from the Zip file. Then just as you did for the USB, the config.plist is renamed from the one that matched your LCD. For a manual mount and install of the ESP bits to disk0 follow same procedure as for the USB. If you previously installed Windows, be careful to not lose the EFI/Microsoft contents.

   Note:

   The Clover config.plist default volume name (the volume to boot automatically) is set to OSX - meaning your new volume is assumed to be named OSX

   If you use a different name, change the volume name or edit the name in config.plist to match. 

   mkdir /Volumes/ESP
   sudo mount -t msdos /dev/disk0s1 /Volumes/ESP
   
   mkdir -p /Volumes/ESP/EFI
   cp -a ~/Downloads/T460/EFI/* /Volumes/ESP/EFI
   
   

5. Install custom kexts on HD

    

   Install the custom kexts from the Zip kexts directory to the /Library/Extensions directory by running EFI/CLOVER/kexts/_kext-install.command

   Note: If you choose to NOT install the custom kexts in the OS /L/E directory, then AppleHDA kext will not work properly. DO NOT remove standard AppleHDA.kext from /S/L/E.

    

   Run this script:

    ~/Downloads/T460/EFI/CLOVER/kexts/_kext-install.command

6. Ethernet Device Installation

    

   This step loads the ethernet kext and resets network device order to have ethernet as en0 (seems to help with AppStore and iMessage etc)

   Note: OSX may already have configured the ethernet, so this step may be unnecessary but it will not hurt anything either for a fresh installation.

   Run this set of commands:

    

   sudo kextload /Library/Extensions/IntelMausiEthernet.kext
   sleep 10
   sudo rm       /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

7. Remove the USB and Reboot to load Clover from the HD

   ​Note: For this first boot, hit the spacebar on your boot selection (OSX) and use verbose mode.

 

 

 

Notes on Custom Kexts

 

All the kexts listed below are contained in the zip file. The origin is listed below if you wish to download them as well. I recommend you use kext install tool to properly copy all kexts to the /Library/Extensions directory.

• FakeSMC.kext (v6.21.1413) - Core hack mechanism. Using Kozlek's version + plugins + custom FakeSMC Info.plist

  A Custom package is included in the Utilities folder so you can install HWMonitor.app - it just selects these 2 Plugins Sensors: ACPI and CPU.

  • ​2 Custom SMC keys are added to Kozlec's standard FakeSMC - FNum (to find the Fan) and ACID (for AC power and eliminate powerd syslog messages every 30 seconds).
• ACPIBatteryManager.kext (v1.70.1) - RehabMan's kext to show/track battery info on menu bar

   

• AppleHDA_ALC293.kext (v9274.12) adapted from ALC292.kext. Note: Keep original/unmodified AppleHDA.kext and add this kext to /L/E for full audio support. Note: requires matching DSDT sections for config.plist layoutID 1. and uses Kext Patch via Clover. 

   

• USB_Injector.kext (1.0.0) - based on RehabMan's UsbInjectAll.kext but modified for T460 XHCI devices. see SSDT-XHC.dsl for related details. 

   

• IntelBacklight.kext (v1.0.10) - RehabMan's kext for smoother/enhanced LCD backlight (dimming) control. 

   

• IntelMausiEthernet.kext (v.2.2.0) - Mieze's Intel LAN kext that supports TSO, EEE and other features. Put this kext in /Library/Extensions

   

• VoodooPS2Controller.kext (v1.8.24a) - New T460 version of RehabMans's PS2 Keyboad/TouchPad/TrackPoint -  

   

  This version has extra T460 definitions in the Info.plist files. And recoded to support 3 real buttons as well ClickPad Right/Left click.

  • Modified Info.plist(s) to add LENOVO T460 override settings. Change defaults to suite your needs in VoodooPS2Controller.kext/Contents/PlugIns/VoodooPS2TrackPad.kext/Contents/Info.plist
  • Reduced MouseMultiplier X and Y for TrackPoint.
  • Note: VoodooPS2Controller keyboard mappings have 3 or 4 finger swipe left/right to back/forward configured for Safari browser

OPTIONAL - used with Dell 1560 Wifi/BT replacement card:

• BrcmFirmwareRepo.kext - RehabMan's kext

   

• BrcmPatchRAM2.kext - RehabMan's kext - but modified to fix sleep/wake timings.

   

• FakePCIID.kext - RehabMan's kext
  • Fake_Broadcom_WiFi.kext - RehabMan's kext

 

Hi @tluck,

your script is returing this error:

 

./_kext-install.command: line 86: cd: /Library/Extensions/AppleHDA_20672.kext/Contents/MacOS: No such file or directory

 

Where is AppleHDA_20672.kext ?

 

Thank you

 

[aleixsr]

ah sorry that is an older script that was hardcoded for my T420... meaning that kext is for the T420 not the T460.

 

ill update the package later but here is revised script that ought to work 

Thank you, I just saw there is:

sudo ln -s /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA

but I don't have AppleHDA.kext ?¿?¿ Does it make sense?

Thank you, I just saw there is:

sudo ln -s /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA

but I don't have AppleHDA.kext ?¿?¿ Does it make sense?

 

Sorry, I found it was on /Backup Extensions folder, I restored it but I don't have any sound device, how did you got it working?
