T420 users:

 

Attached is a current full /EFI pack for the T420 for Clover and OSX 10.8.5 (12F45) and 10.9.4 (13E28).

 

Caveats:

My system is a T420 1600x900 LCD with dedicated Intel HD 3000 Graphics Only ... So can't speak to enabling Nvidia gfx myself.  This is a zip contains what is working for me. The guide outlines the 2 phases: (1) how create a USB installer and install OSX, and (2) run OSX for your HD. If your HW is not similar as mine, the included DSDT and configuration files may need to be retrofitted to work for your system. 

 

Highlights:

  • A config.plist + kexts for Clover to boot without a custom DSDT file for the OS install 
  • Separated by LCD size -  config.plist with a custom DSDT for Clover to boot via UEFI, post OS install
    • ACPI.1600x900 folder - has dsdt.aml for high-res LCD with DualLink=1 and injects a good/patched EDID
    • ACPI.1366x768 folder - has dsdt.aml for low-res  LCD with DualLink=0 and no injected EDID
    • Note: the CPU section is not needed in the config.plist anymore, as Clover computes Bus Speed ok in later revs - check it though! should be around 99676 - 99700 to keep system clock accurate.
    • A current Clover and Kext Bundle for 10.8.5+10.9.3 is here in this post
  • An older non-maintained Kext Bundle for 10.8.4 is in post #241

ACPI Notes:

  • the new DSDT conforms (more) to the native unmodified kexts ACPI spec... may not have to replace the AppleACPIPlatform.kext.
  • AppleACPIPlatform.kext v2.0 (10.9.x) works with new DSDT
  • AppleACPIPlatform.kext v1.8 (10.8.5) works with new DSDT
  • AppleACPIPlatform.kext v1.7 (10.8.4) works but does not wake as well when you have external eSATA/USB drives.  
  • Notes:  there are kext folders for 10.8 and 10.9 - but many of the kexts are the same.

 

Custom Kexts

 

- use kext inject or install in /S/L/E (/System/Library/Extensions).

  • FakeSMC.kext (v6.x.xxxx) - Core hack mechanism. Using Kozlek's version + plugins - Note: Follow link to download full package - so you can install HWMonitor.app etc (no need to re-install FakeSMC.kext unless there is a newer rev - so if you do install - just select these 2 Plugins Sensors: ACPI and CPU)
  • AppleIntelE1000e.kext (v2.4.14) - Ethernet (gigE) - goes in /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns
  • VoodooPS2Controller.kext (v1.8.13) - RehabMans's PS2 Keyboad/Trackpad -   Note: Follow link to get full package and installation instructions to install daemon and pref-panel 
  • ACPIBatteryManager.kext (v1.52) - RehabMan's kext configured for v3 ACPI instructions to show/track battery info on menu bar
  • ACPIBacklight.kext (v2.0.3) - RehabMan's kext for smoother/enhanced LCD backlight (dimming) control.
  • IOAHCIBlockStorageInjector.kext -  configured to make just the DVD device appear internal so iDVD player works. 

Mountain Lion (10.8.5)    These kexts are 10.8.5 specific:

  • AppleHDA.kext (v2.4.7 patched from 10.8.5)- for full audio support - note: requires matching DSDT sections using Conexant Codec and layoutID 12. Note: AppleHDA.kext has Manwe150's fix/additions for dock ports.
  • BroadcomBluetoothHostControllerUSBTransport.kext (v4.1.7 with patched Info.plist from 10.8.5) - adds ProductID 8575 to make BT work! Put/replace one in /S/L/E/IOBluetoothFamily.kext/Contents/PlugIns

Mavericks (10.9.4)     These kexts are 10.9 specific:

  • AppleHDA.kext (v2.6.3 patched from 10.9.4) - for full audio support (analog and DisplayPort/HDMI) Note: requires matching DSDT HDEF device sections using layoutID 12. (kext is patched for CX20590 codec)
  • BroadcomBluetoothHostControllerUSBTransport.kext (v4.2.6 with patched Info.plist from 10.9.4) - adds ProductID 8575  in Info.plist to make BT work better! Put/replace one in /S/L/E/IOBluetoothFamily.kext/Contents/PlugIns

​10.*-Chameleon - extra patched kexts for use with Chameleon 

  • AppleIntelCPUPM.kext (patched 10.8.5 and 10.9.3) - not really necessary to install/replace with clover since it does the patching. Optional Install in /S/L/E for Chameleon compatibility.

General Notes, Fixes, and Features of the Zip

  • Clover configuration files (config.plist) 
     a ) config.plist               - (default) to use the custom DSDT and WITH extra Clover patching
     b ) config.nodsdt.plist   - this testing version - everything works except battery levels
                                           - remove/rename DSDT.aml and use built-in/BIOS DSDT with Clover patching
  • Model is to set MacBookPro8,1 explicitly in config.plist. (needed to get proper DP/HDMI/DVI/VGA FrameBuffers)
  • Zip includes extra and custom kexts plus cVad's Kext Utility v2.5.7 for easy kext installation (or you can use manual kext  _install_SLE.bash script)
    Note: VoodooPS2Controller keyboard mappings have 3 or 4 finger swipe left/right to back/forward for browsers configured.
  • removed ssdt.aml files from zip and added ssdtPRgen-clover.command script so you can create your own SSDT P/C state tables
  • High-res vs low-res config.plist (and DSDT) are very consistent - difference is EDID and DualLink settings.
  • Note: for 1600x900 the EDID is injected by Clover and is also in the 1600x900 version of the DSDT for - there are 2 sets of timings for 60 and 50 Hz options
  • Added folder for Displays/Overrides (for more natural color gamma curves and more screen size options) in this zip
  • Swapped out VBoxHFS-64.efi for HFSPlus-64.efi - supports installation bundles and Recovery HD better.
  • Clover patches string for SNBFrameBuffer kext to fix LCD brightness max level - now its the same brightness before and after sleep. Thanks to Timewalker75a (again!)
    Note: this same kext patch replaces the 4th port/buffer (DVI on dock) with VGA on left side. The 4 ports after patch are: LCD, DisplayPort on side, DisplayPort on dock, VGA on side. If you need DVI on the dock - then you can either not do this! Or replace the 3rd port (DP) if you want the VGA.
  • Thinkpad theme (updated) to show badge (disk type) and added a Mavericks and Yosemite Icons instead of using generic apple.
  • ScrLk and Pause keys change LCD brightness. ThinkPad button toggles fan to high speed.
  • Alt key is the Command key and Microsoft flag key is the Option key.

DSDT tweaks since 10.8.x version:

  • DSDT includes source and binary with recent patches (some beyond Clover and manwe150's original post edits)
  • Added MaxBeepBootVolume to DSDT to rid AppleHDA assertion on startup

  • Shutdown fixes in DSDT  _PTS and _WAK (thanks to TimeWalker75, RehabMan and Manwe150)

  • Change/fixes to reset LEDs for proper sleep/wake status

  • Battery fixes to use native/current ACPIPlatform.kext with Rehabman's ACPIBatteryManager.kext - no need to rollback or patch AppleACPIPlatform.kext anymore.

  • For 1600x900 LCDs, added an EDID that removes infamous HD 3000 glitches and buffer hangs.

  • PNLF additions from RehabMan for smoother LCD backlight control with ACPIBacklight.kext

 

INSTALLATION GUIDE

 

BIOS settings:

- Most defaults settings will work - but make sure SATA is set to AHCI mode and disable VT-d in the Virtualization option.

- Disable Nvidia/Optimus (use HD 3000 only unless you really know what you are doing!)

- The custom DSDT is based off BIOS v1.46 (flashed with whitelist mod or original)

 

Part 1 - OS Installation

 

Install (or reinstall/update) OS X to a GUID/GPT formated disk from a USB using the standard Install OSX .app

You can use this zip to build a Clover-based USB installer and then install on HD for UEFI boot.

  • For Mountain Lion (10.8.x) USB installer
  1. Download Mountain Lion from the App Store - puts in /Applications
  2. Partition an 8GB USB as GUID (use option menu to change from MBR) - name this partition USB
    Note: if you have a larger USB (say 16GB) you can split into 2 8GB partitions, so you can have 10.8.x and 10.9.x installers on the same USB key
  3. Use Disk Maker to create an Installer from the downloaded Install Mountain Lion OSX.app

    Note: you may need to disable BlueTooth in the BIOS to install 10.8.5 directly. Enable later when you boot up.
  • For Mavericks (10.9.x) and Yosemite (10.10.x) USB installer
  1. Download latest Mavericks from the App Store - default location is in /Applications
  2. Partition an 8GB USB as GUID (use option menu to change from MBR) - name this partition USB
    Note: if you format the USB as MBR, then you will need to install the Clover boot tools (after) - see note at the bottom.
  3. Run this command:
    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ OS\ X\ Mavericks.app —nointeraction
    
  • Common steps
  1. manually mount ESP of USB and copy the entire EFI folder (from the zip) onto USB ESP
    For example, assuming the USB is disk2:

    sudo mkdir /Volumes/ESP-USB
    sudo mount -t msdos /dev/disk2s1 /Volumes/ESP-USB
    sudo cp -a ~/Downloads/T420/EFI /Volumes/ESP-USB

    Note: run "diskutil list" on the command line to find your USB disk
             if your USB is MBR format - just copy the EFI structure to the / (root) of the main partition instead!

     

  2. Setup configuration files to match your LCD resolution in /Volumes/ESP-USB/EFI/CLOVER:
    1. ​​​Rename ACPI.1600x900 to ACPI or rename ACPI.1366x768 to ACPI
    2. Rename config.1600x900.plist to config.plist or rename config.1366x768.plist to config.plist
       
  3. Boot from USB and select Install OSX
     
  4. Install on your GUID OSX partition!

TIP: enable debug mode for Disk Utility to see all the partitions (such as hidden EFI). From the Terminal command line, run this:

sudo defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

Part 2 - Post OS Installation and Setup on HD

  1. Boot Clover from USB - but now select the new OS X partition to start OS X. 
    This will boot up OS X with Clover using the custom kexts with the "top" level config.plist.
     
  2. Install Clover on to HD 

    a ) Run the full Clover_v2k_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:
    [attachment=134184:clover-pkg-install.png] After you close the pkg installer, then follow these step:

    b ) REPLACE the ESP (EFI folders) contents with the exact CLOVER folder as your setup on USB from steps above. If not still automatically mounted by the installer pkg, manually mount the ESP of your HD on say /Volumes/ESP. Then copy and replace the folders /Volume/ESP/EFI/CLOVER and BOOT from the USB installer you just built and used.
     
  3. Install custom kexts on HD
    • Recommended: Use the folder with its config.plist with the custom dsdt.aml (as is) to start.  And install the custom kexts from the zip folder to the /System/Library/Extensions folder. 

      Install these kexts from the zip folder EFI/CLOVER/kexts/10.[8 or 9] by either method:
      - if you don't have a GUI, use the included shell script _kext-install-SLE.bash
      OR 

      - if you have a GUI, then use the Kext Utility tool (from cvad included in Utilities folder). 

      Note: If you choose to NOT install the custom kexts in the OS /S/L/E folder, then modify the config.plist to force injection of these custom kexts. Note: Injecting AppleHDA and BroadcomBluetooth kexts from the ESP may conflict unless the originals are removed from /S/L/E. 
       
  4. Install (copy) the DisplayVendorID-* folders
    These are from the zip file and should be put in /System/Library/Display/Overrides
    Note: These provide alternate color correction and gamma curves as well as more screen sizes for just a few LCD models. 
     
  5. Reboot - Boot Clover from HD vs USB.
    Hit the spacebar on your boot selection (OSX) to start up
     without kext caches to make sure it loads all the custom kexts just installed. 
     
  6. Ethernet Device Install
    Note: This step is optional but usually needed after a fresh OS install.
    This loads the ethernet kext and resets network device order to have ethernet as en0 (may help with iMessage etc)
    Run this set of commands in a terminal window:
    sudo kextload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleIntelE1000e.kext
    sleep 10
    sudo rm       /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
    
  7. Create a custom SSDT
    This is for proper P/C states to match system (optional - but this tool may do a better job than Clover) 
    Run the custom ssdtPRgen-clover.command script in Zip Utilities folder. It should ask you if you want copy ssdt.aml to your ESP ACPI/patched folder, otherwise copy/move ssdt.aml to the same location as your custom dsdt.aml 
    which is: /Volumes/ESP/EFI/CLOVER/ACPI/patched

    Note: it will copy iasl from the Utility folder to /usr/local/bin/iasl

     
  8. Reboot a final time to use the new SSDT table (and other changes from last 3 steps)

 

Known Issues:

  • E1000e ethernet hang: with the 2.5.4d and 3.0.4.x version of the Intel E1000e ethernet kext, I have seen some random problems. I rolled back to v2.4.14 and have not had issues lately. The issue crop up under heavy file copy/transfers and your ethernet stops working with a lot of log messages that only a reboot fixes. 

Note: the 4 problems listed below happened with earlier versions of Clover, but on 10.9.2 or later, and with the rewrite of Clover and OsxAptopFixdrv-64.efi, these UEFI/ESP issues are seem to be a thing of the past.

  1. putting to sleep can result in flashing/hung state

  2. built-in keyboard mute button can totally freeze system - works fine from software (i.e. apple bluetooth KB)

  3. shutdown may not go all the way to full power off (OS shuts down but at black screen with fans/lights on)

  4. built-in PS2 keyboard/trackpad may disappear after sleep/wake 

Optional: Boot with Clover on MBR USB

 

One can still boot from the HD using UEFI. But one can also create a bootable MBR formatted USB with CloverEFI. This boot method may mitigate or eliminate any random UEFI issues. The exact same EFI folder can be used. To make a bootable MBR USB:

  1. Format the stick as MBR (which is usually the default) with a single FAT32 partition named USB.
  2. Optionally copy the OSX installer to USB (same command for GUID USB above) but must be done before steps below!
  3. Then with Clover_v2k_rxxxx.pkg, install to the USB for "legacy CloverEFI" boot.  That is: Uncheck the top 2 items, and in Bootloader check the 2nd option to install boot0af.
  4. After the Clover pkg installer is finished and closed, then replace the EFI/CLOVER folder just like you did on the HD. the EFI/BOOT folder is not needed. Note: the HD ESP EFI folder and USB EFI folder should be exactly the same now.
  5. Then from the BIOS, set USB-HDD as top boot option (so you don't have manually boot from USB vs the HD)

Thanks to Clover EFI Bootloader I was able to achieve almost perfect HacBook Pro from my Lenovo T420

This guide is work in progress and I’ll try to update it as often as I can outdated! For more updated guide head to tluck's post #481 (thanks tluck for taking over)

 

Why UEFI Only?
Faster boot time, better hardware detection, native Mac OS X Installation process and Auto create Recovery HD, working iCloud and iMessage to name a few. But in general you will achieve almost perfect Macbook Pro clone that will most likely survive all future System updates.

Note: I’ll be focusing on Mountain Lion but I guess Lion would work equally good.

Lets start by preparing Mac OS X install media.
You will need:
- Working Mac OS X 10.6 or later (Hackintosh, Virtual machine or real Mac)
- 8GB+ USB pen-drive
- Legal copy of Mountain Lion install app
- and an app called Lion Disk Maker
- my custom Clover Package: Attached File  Clover_v2_r1625k0.pkg.zip   5.44MB   1924 downloads

Prepare Mountain Lion install media using Lion DiskMaker.

LDM.png

Making install media bootable on your ThinkPad
Run my custom Clover Package and change the install destination to the Mountain Lion install media you’ve just created using Lion DiskMaker. Generaly you don't have to worry about anything else it is all customized to work best on all ThinkPads.






Custom Clover 1229k0.png

Note (optional): At this point you can use another FAT32 formatted pen-drive to install Clover on to it. This pen-drive needs to be capable of storing at least 25MB+ of data.

System installation
Insert prepared OS X Mountain Lion Install Disk - 10.8 in your ThinkPad and set to boot in UEFI Only mode. And wait for the boot loader. You should be presented with screen like this:






screenshot0.jpg

Now start the installation process just like you would on a normal Mac. Partition your drive with GUID table and install.

Adding Extra drivers using myHack
You now should be running vanilla Mac OS X 10.8. Before you start upgrading and instaling software now is a good time to add missing drivers and install them in a clean and proper manner using myHack.
1. Download Extra Folder: Attached File  Extra.zip   1.75MB   1036 downloads
2. Download myHack and place it in your Application folder
3. Run myHack and choose myFix. When asked about Extra folder choose "Use My Own" and point to downloaded Extra folder from step 1. Reboot and check if everything is working fine. By everything, beside AppleACPIPlatform.kext ver 1.3.5, I mean Sound and Battery meter cause these are the only kexts that are in Extra/Extentions

Extra-Extensions.png

Making your custom configuration using OEM folder
... under construction...

Booting Clover EFI Bootloader from system drive
It's time to get rid of the osx pen-drive you've been booting all the time and install my custom Clover to your main disk and boot directly from your hard drive EFI partition. This step is identical to the "Making install media bootable on your ThinkPad" but this time you will be using your main drive. Just make sure your disk drive is selected when installing.

Note: Now You can customize your installation. You have the choice to install Clover Preference Panel and Optional RC scripts.






Clover1625k0.png CloverPrefPane.png CloverPrefPane1.png CloverPrefPane2.png

Remove pen-drive and reboot. If all went well you should be booting from your hard drives EFI partition now. Good luck!

.…. to be continued.

Update 2013-01-20: Flashed latest UEFI Bios version 1.43 + whitelist and started fresh DSDT patching

Update 2013-01-30: Uploaded new LenovoEFI_Pack_Beta2.zip (from now on I'll be attaching latest version to this thread). I've started using the EFI/OEM/4180A32 folder specific for my T420 model and added minimal config in the root that should work for everyone else (testers needed). My latest DSDT.aml in EFI/OEM/4180A32/ACPI/patched and updated ThinkPad theme is included.

Update 2013-05-15: Updated the post to reflect some changes and progress made in this topic. Using custom Clover r1625 that has all the stuff Lenovo UEFI user needs. This one is enabled to install to ESP by default with ThinkPad Theme and RC scripts and example EFI/CLOVER/OEM/4180A32 folder.

Yes and Yes - but you need to patch USB for sleep to work.
dsdt.aml included in clover EFI/ACPI/patched/dsdt.aml does not have this patch. I'll add info about DSDT patching later.

Yes this guide will work but remember that I use kexts (drivers) specific for Lenovo ThinkPad's and as I mentioned before my DSDT.aml that will KP on your machine.
So in your case delete:

EFI/ACPI/patched/dsdt.aml
and try it out.

I can't get my hardware monitor to work. Try to run it and I got KP.....

Did you use some special kext for the hardware monitor? The one I am using is from iAtkos ML2

If by hardware monitor you mean HWMonitor.app than you just need the latest FakeSMC.kext and in our case CPUSensors.kext and ACPISensors.kext. You can find them in my "EFI/kexts/10.8" and the minimal readout should look more or less like this:

I'm guessing that KP is due to different version of FakeSMC being loaded from iAtkos .

Today I've made a display override for my HD+ Panel (1600x900) based on MacbookPro9,1(DisplayVendorID-610/DisplayProductID-9cc7) and named it Lenovo LCD.

The display profile default is warmer using this file and I have added some extra resolution choices in scaled mode.

Just unzip it and copy entire DisplayVendorID-30e4 folder to:

/System/Library/Displays/Overrides/

Today I had the chance to test out the Display Port to Hdmi cable that I've ordered for 7$ from China (free shipping) and I'm happy to report that all is working great.

Posted Image

All testing done on my Samsung 40" FullHD LED TV. Full resolution support. Stable graphics with no artifacts that I keep on hearing here and there. Even done some OpenGL testing to see how much FPS can I get in case of gaming on the big screen. Mirroring works. The HDMI sound output works both in direct mode (sound in TV) and pass through to my Onkyo receiver.


Here are some screenshots:

Hey, it's maybe a little bit off-t, but I have a t420 wich I want to run on OSX. I've been in the hackintosh business for a few years, but since the new Sandy Bridge and further I admit I lost track of the scene a bit.

I have tried to install with the "OSX 10.8 bootable usb method", the one you need the raw file and a windows pc for,
I've tried the ##### method, also myHack etc etc.

With the bootable usb method I can boot in installation, but osinstall.mpkg failes to load, so there's no custom install option. When I install and reboot, I get stuck after the IOBluetooth succes message, which is the last one before loading graphics. This "freeze" happens while loading ##### etc too. I've tried using all different flags etc but no succes.

How did you manage to get your graphics working? Do you have two GPU's or just the Intel graphics?

My setup is:

T420
i5 2520m vPro
4gb ram
HD3000 graphics
1600x900 screen

and the standard stuff as bluetooth 3.0, wan etc.

Hope you have some tips for me ;)

Try starting from step "Clover installation" - use another FAT32 formatted pen-drive and copy the EFI folder to it and try installing again in UEFI only mode. I won't support other methods.
Also instead of hardware specs I rather you tell my your ThinkPad serial number. Good luck

My serial number is 4236Z9U.
Thanks for the fast reply, and also my compliments for the work you're doing!



NB: Tried to copy your files from EFI, didn't work OOB. What worked for me is to download latest Clover package installer (v2_rL971), install it to USB and then copy (and replace where needed) your files from "EFI" folder to the EFI folder on the USB. Now I can boot Clover, it's a start haha.


UPDATE: I have followed your guide, and now I can actually boot into the installer. Only issue is, my display does not work. I noticed that I got a black screen after booting (instead of hanging at bluetooth succes it goes on running to graphics), but when I clicked something my usb did go do something. So I figured my graphics were working now, only my internal LCD did not. I switched to external VGA as default boot screen in my UEFI bios, and that, in fact, works. I guess it tries to go 1600x900x32 on my 1280x1024 screen, but it's working.

Do you know what I have to change to make my LCD working, is it something in Clover or in my kexts?

You have almost identical hardware specs to mine so I advice you to rename the 4180A32 folder inside EFI/OEM/ to 4236Z9U and report back.


BTW: Are you sure you have the correct UEFI booting settings in your ThinkPad Setup? (Startup > UEFI/Legacy Boot Priority [UEFI First])

ThinkPad Setup


I still can't make up my mind regarding the best ThinkPad Setup configuration but it seem that some setting are essential for booting Mac OS X:

Essential:
Config > Serial ATA (SATA) > SATA Controller Mode Option [AHCI]
Security > Memory Protection > Execution Prevention [Enabled]

Security > Intel ® VT-d Feature [Disabled]

My other settings:
Security > Security Chip > Security Chip [Disabled]
Startup > UEFI/Legacy Boot [Both]
Startup > UEFI/Legacy Boot Priority [UEFI First]

Yeah I have the system up and running now, from my internal screen with right resolution. Sound and ethernet work as well now.
Only issue, I get a KP after a few minutes.

panic(cpu 2 caller 0xffffff7f807ff1df): No HPETs available...CPU(s) configured incorrectly
Debugger called: <panic>
Backtrace (CPU2), Frame : Return Adress
and after that a lot of computer language, which probably is the adress of where it got stuck or something.


I'm going to try changing stuff in bios first, turning off hypertheading etc, maybe it works maybe not, I'll post updates.
I'm still running original UEFI/BIOS by the way, because I wasn't planning yet on changing my wireless card.

I think some things in your DSDT aren't the same after all, but the namechanging thing did work for the rest. Only problem now is that I do not have any knowledge of modifying DSDT's...

I think there is my experimental DSDT.aml in the patched folder, try replacing it with the one I'm using right now.
