Lenovo ThinkPad T420 with UEFI Only

Recommended Posts

@FungFlex - what is your T420 model? do you have high-res or low-res monitor? if you have low-res don't use DualLink=1. which dsdt are using. one has Dual Link on and one doesn't.

@tluck-

I'm creating the USB for the final Mavericks release using your latest guide on post #486, but the USB doesn't seem to be bootable...

Am I missing something?

 

Thanks,

aj

{censored}. sorry all. I completely forgot to mention (and update the zip file) that I replaced VboxHFS-64.efi with HFSPlus.efi from here:

 

https://github.com/STLVNUB/CloverGrower/blob/master/Files/HFSPlus/x64/HFSPlus.efi

as someone pointed out it seems to be able to read the install bundles better. and it does!

Hi, the link for the bios does not work, it's maxed out. Can you attach it here?

Thanks,

AJ

 

the link appears to be broken again. could someone post a new one? thanks.

i can't get any osx to work with my t420 (type 4180-b95 has nvs 4200m) and I'm not sure where to start.

 

ive tired lion, mountain lion and mavericks. i preferably want mavericks but will start where i need to, i even tried pulling the HD out of a macbook and booting that

 

currently when i try to boot the usb installer for any version of the os i made (which worked on a real mac at least 10.7 and 10.9 did) it does what it did in this video

My t420 Video also if i back out of that black screen wight eh small dash if it lets me it goes back to clover but it is frozen most of the time

when i try to boot the lion from a real mac i get this version of Mac OS X is not supported on this platform

reason: 4180b95

but when i boot the recovery partition it goes to  a white screen with a beach ball after verbose mode but if i try with the -x flag it doesn't even try to boot it goes to saying i can't find the mach_kernel
id obviously prefer a fresh install by this or another guide but i seem to not have any luck with it


idea's?

thanks

@anarchy99

 

i would turn off NVS for now.

 

Note: a vanilla mac installer needs FakeSMC - same for the HD from a real mac. these will not boot up unless you inject FakeSMC (and  VoodooPS2controller unless you have USB keyboard/mouse).

 

are you using the clover config from my zip for your EFI? what EFI drivers do you have installed. it acts like its not even reading the USB? canyou may need HFSplus.efi to boot from recoveryHD.

Using your clover config I was able to boot and install Mavericks YAY!!

I did have to disable the discete graphics :-(

So far audio seems to work, it sees ethernet but doesn't text any cabel and no wifi

 

I installed a Dell 1390 wireless card that I stripped out of an old hackintosh into the bottom mini PCI-E slots and it doesn't seem to detect at all

does anyone know how to get that working?

I read somewhere that someone said it was for msata and USB only, but the t420 hardware maintenance manual refers to it as 1070 PCI Express mini card for wireless WAN

If I could add rather use that  bottom slot then have to buy a mini PCI half card or whatever it's called for under the keyboard

@anarch99 - you will get ethernet if you installed the AppleIntelE1000e kext ... but wifi AFAIK is only works with modded bios and then you replace the intel wifi with the mini express card. the  bottom slots will not work for wifi. for wifi, i use a USB wifi.

Ok all, well after some tricky issues I am back on Mavericks and able to boot but in only one of two scenarios:

 

1) Boot directly to Mac partition on UEFI Clover boot loader and deal with quadrant display issue

 

2) Boot off old formatted drive with Clover r1625 which fixes display and breaks sound

 

I am having a hell of a hard time customizing things. After I have installed Clover and I restart the computer should I still see the ESP partition? This consistently disappears the moment I restart my computer.  Additionally if I try to select the EFI partition on the Clover boot screen it just flashes.

 

Back on Mountain Lion my startup would be selecting EFI than my Mac drive and it worked great but no luck.

 

Finally, I’ve seen totally mixed answers on where I should find my product ID.  Using various methods it seems like my DisplayProductID is 738 but I’m not even sure that is the right number I should be renaming the OEM folder too? I've included below stuff I pull from when I did the ioreg -l:

"IODisplayEDID" = <00ffffffffffff0030e4e2020000000000140103801f11780a43459759578e28215054000000010101010101010101010101010101018025408060841a303020350036ae10000019000000000000000000000000000000000000000000fe004c4720446973706c61790a2020000000fe004c503134305744322d544c42310038

"DisplayProductID" = 738
"DisplayVendorID" = 12516
"IODisplayPrefsKey" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IGPU@2/AppleIntelFramebuffer@0/display0/AppleBacklightDisplay-30e4-2e2"

To answer TLuck’s question, yes low res model with i5 2.49ghz

@FungFlex - 

 

what DSDT are you using? if you are booting using the EFI i posted - there are 2 configs and matching DSDTs. since you are low-res, you should be using the Low-Res 4236Y33 version.  

 

the EDID shown above is consistent with the the High-Res version 1600x900 LCD

 

the EFI partition (ESP) is automatically mounted by a clover utility. this is convenience for you.

I am using the 33 version as I believe I have the low-res version. The EDID I ran was done while I was stuck in quadrant mode if that maybe explains why it would show the 1600x900 one. Not sure how to confirm to be honest, this computer barely ever ran windows :-)

 

I guess my confusion is, when I install Clover the parition named "EFI" appears (although only one time was it named "ESP") when that happens I drag your zip file contents into the Clover/Boot folders and when I restart the computer that "EFI" partition is gone. Is this normal?

Also, on the clover boot menu, if everything is installed correctly what do you select when booting up?

 

Finally, the folder I am supposed to rename is "4236Y33" correct? The question is, how do I know what to rename it properly? Where do I find the appropriate string?

@FungFlex - 

 

use the console app to look at the clover boot.log - it will show you the productID.  or use the Clover Options Menu to get the Product ID - forget where exactly. thats the name of your OEM folder. should match whats on your label on the bottom of system.

 

there is a dsdt.aml in /EFI/Clover/ACPI/patched - this is for high-res - same as the one in OEM/4236AT9/ACPI/patched. thats why you are getting 4 panels. this dsdt has duallink=1 and injects a 1600x900 EDID. replace it with the low-res one. 

 

when you rename OEM/4326Y33 to match your ID, it will use the stuff in this folder vs the top level. 

 

the Installer mounts the ESP on /Volumes/ESP. there is an option to have clover utility mount the ESP upon boot up. it mount it at /Volumes/EFI (these are installed optionally by the Clover .pkg installer. 

 

when you boot, select your OSX partition.

So happy I could kiss you! Although I'm probably not your type ;-)

 

Everything is working perfectly, I'm running Mavericks and everything is fully functional (sound and display! hooray!)  Only outstanding question is previously on 10.8 I booted with Kogen's custom clover build and it must have injected a different trackpad kext as I was previously able to do some 3 fingered gestures for mission control and switching between spaces. These seem to be broken, is that a 10.9 thing or should I pull a kext from his bundle?

 

Having some minor issues with iMessage but I haven't done anywhere near enough troubleshooting on my end to diagnose yet.

Following the instructions for 10.9 install from post #486:

 

 

 

  • for 10.9 install USB
    1. Download from App Store (puts in /Applications
    2. Partition 8GB USB as GUID (use option menu to) - title the partition USB
    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
       
    4. manually mount ESP of USB and copy the clover EFI folder onto USB ESP (assuming the USB is disk2)
      mkdir /Volumes/ESP-USB
      mount -t msdos /dev/disk2s1 /Volumes/ESP-USB
       
    5. rename OEM OEM.NU for USB installer so it will use top level config.plist that will inject kexts
    6. Boot and install OSX!

 

When I boot into the installer I get the 4 quadrant screen deal. Searching around this same topic I saw to go into config.plist (in this case top-level) and set Dual Link to 0 which I have done but still get the split screens. I've tried booting into safe mode but it only causes an error and reboots before it even gets to the installer GUI. What else can I adjust? I'll try installing anyway since the fix will need to happen when I am done with the vanilla install as well.

 

Thanks,

 

Anthony

For me the full install happened in "quadrant" mode. It wasn't until install was fully done and I installed clover and fixed the OEM folder that quadrant display was fixed.

I guess i need to augment the instructions for better handling of low-res LCD configurations. for non 1600x900 LCD, to fix this quadrant thing on your USB installer and HD (until you rename the OEM folder to say 4179W1F for example), copy the generic (low-res) dsdt.aml into use on the top level. When there is folder in OEM that matches your product ID, clover will that instead. the

 

cd to your mounted ESP location 

cp EFI/CLOVER/OEM/4236Y33/ACPI/patched/dsdt.aml EFI/CLOVER/ACPI/patched/dsdt.aml

i get stuck

 

stuck on IOBluetoothHCIController Missing Bluetooth Controller Transport

 

upgrade on 10.9

Did you try either disabling Bluetooth in the BIOS, or in my case I use a USB bluetooth adapter as my model didn't have it built in, I simply removed it during install.

Updated...
Finally work with 10.9.. :) thanks tulk..for your tutorial.
 
@Tulk, how to read OEM/4xxxx folder in ESP in 10.9 ? cause if im rename OEM.NU to OEM, the configuration clover will read in directory OEM/config.plist and make not boot properly ( stuck on IOBluetooth )

iMessage, iCloud etc using apple ID, not work... :( how to solve this problem ?

 

Updated this morning Oct 31st

 

iMessage, iCloud etch using apple ID work !!!

To do this:

 

1 Remove all Network interfaces

2 Remove /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

3 Reboot

4 Readd your Network Interface.

the point of the OEM folder is to have a configuration for the HD versus USB. i use the top-level for USB installer - set to Inject Kexts. I make the assumption you will put the custom kexts in /S/L/E and not need to inject them. So If you have a high-res LCD rename 4236AT9 to match your ProductID.

 

if you have low-res LCD, then rename 4236Y33 to match your ProductID.

bluetooth should be fixable by either replacing or editing:

 

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

      Hi Hypervisors,
       
      I have been working to move my Late 2009 Xserve MacOS Server onto Ubuntu 18.04 LTS QEMU/KVM based virtual machine using OVMF and Clover.
       
      After much effort and testing based on the following information from: Kraxel's, Kholia, Gordon Turner and Clover site:
      https://www.kraxel.org/blog/2017/09/running-macos-as-guest-in-kvm/
      https://github.com/kholia/OSX-KVM
      https://gist.github.com/gordonturner/2a2e5ecde5e7860b52e2
      https://clover-wiki.zetam.org/Home
       
      I have now managed to get OVMF/Clover boot and install of MacOS Sierra.
       
      I started with Ubuntu 16.04 initially but this required download and compile of QEMU to get update of machines to: pc-q35-2.9 or better, so I moved to Ubuntu 18.04, which has pc-q35.2.11 available as standard.
       
      So I am now working with standard Ubuntu 18.04 LTS based systems with following packages: kvm/qemu/libvirt/bridge-utils/ovmf/virt-manager
       
      As I want to use PCIe Passthrough for a number of PCIe card currently installed in the server (SmallTree 10GbE & Areca ARC-1883 SAS RAID) I set up my machine with linux kernel boot configuration (/etc/default/grub) of: 
      GRUB_CMDLINE_LINUX_DEFAULT="iommu=1 intel_iommu=on" (as my machine is intel VT-d based HW virtualisation)
       
      This resulted in creation of a number of iommu groups (see /sys/kernel/iommu_group directory for this and this posting for information: https://forum.level1techs.com/t/ubuntu-17-04-vfio-pcie-passthrough-kernel-update-4-14-rc1/119639 , noting that Ubuntu 18.04 LTS has kernel version: 4.15.0-22-generic so there is no need to do kernel update for iommu to work).
       
      Using bare minimal Clover config.plist:
       
       
      And following Clover UEFI drivers:
       
      I can boot MacOS, but it is very very slow... it sits on the apple boot logo for over a minutes before finally moving onto the progress bar.
      The other problem I have is that no PCI or Network devices appear in the "About This Mac" System Information Report and I cannot get any network connectivity from bridged E1000 network device.
       
      Here is my virtlib.xml dump for the virtual machine:
       

      Can any one advise of whether I need to update the CLOVER config.plist to add extra items in to allow network and PCI Passthrough to work.
       
      Thank you.
       
      Regards,

      Release v2018.05.17 on GitHub Updated to Clover r4458 Updated Lilu.kext - supports both Sierra and High Sierra Updated AppleALC.kext - supports both Sierra and High Sierra + added back DVMT patch for 10.13.2+ Updated VoodooPS2Controller.kext (RehabMan version) + SSDT updates for T460 Added Frank's T470p DSDT files
        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 (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.

      Hi there, time for my first guide after asking so many things
       
      Updated for newer Clover versions and with additional instructions for more apps: gdisk and RU.
       
      So what may be overlooked sometimes in the whole boot loader discussion is the ability of UEFI to do more than just loading an OS. This is why I see ".efi" files as "apps" because in fact they just are, built on a special kind of API: UEFI. So, you can actually do stuff like editing, diagnosing, testing certain stuff at the lowest possible system level without booting to any OS.
       
      DISCLAIMER: Use this guide at your own risk! For educational purposes only! Should do not any harm, but remember you are dealing with rather low level stuff. But at least for me everything went flawless.
       
      Prerequisites:
      Working clover installation Clover Configurator or some app to edit the config.plist  
      1) Memtest
       
      This is how to install the UEFI version of Memtest with Clover:
      Download memtest, I used this link: Image for creating boot-able USB Drive Open the archive by double clicking on it. Mount the file memtest86-usb.img within by double clicking again. Now, you should see a folder named EFI in this volume, containing a folder BOOT. Open it. The files containing it are the actual app, in 32 and 64 bit versions. Think in almost all cases we want to use the 64 bit version. Now, mount your EFI partition, using Clover configurator. Create a folder named MemTest86 in the EFI folder on your main drive. Copy all files in the EFI/BOOT folder from the mounted image to your newly created folder. That ends the basic setup! Now, we add the correct Menu entry to the clover boot menu, so that we can actually start this app.
       
      Get into clover configurator, open your standard config.plist from your boot drive and go to the GUI section. Under "Custom Entries", add an entry like this:
       

       
      Please note while the path you enter is not case sensitive, you must make sure you use the backslash "\" for entering paths, and not a slash. So basically what we do is tell clover where it can find the app, give it a name, and tell clover it is a "Windows" app. Note: with older Clover versions we had to set this to "Linux", but for now "Windows" is the setting that works.
       
      If you prefer to do a manual config, add this entry to your config.plist, under GUI/Custom/Entries:
      <dict> <key>CustomLogo</key> <true/> <key>Disabled</key> <false/> <key>FullTitle</key> <string>MemTest86</string> <key>Hidden</key> <false/> <key>Ignore</key> <false/> <key>Image</key> <string>\EFI\CLOVER\themes\Icons\os_mint.png</string> <key>Path</key> <string>\EFI\MemTest86\BOOTX64.efi</string> <key>Type</key> <string>Windows</string> <key>VolumeType</key> <string>Internal</string> </dict> Now, save and reboot and you should see the newly created entry. Note that I also used a custom Icon - this is optional - in case you don't you will just see a generic windows icon instead:
       

       
      And this is how it looks like:
       

       

       
      PS: also noticeably faster and you get also more features with this version than with the older version, for example it does now write a log file. For more Information, see: http://www.passmark.com/forum/showthread.php?4315-Memtest86-Version-5-Beta-%28Pure-UEFI%29
       
       
      2) gdisk
       
      Another app you can use is the UEFI version of gdisk (aka GPT fdisk), which you can use to edit and change your partitions.
       
      Warning! Install and use this app at your own risk! If you do something wrong here you might nuke your drive(s), so only use that if you know what you are doing.
       
      This is how to do it (even easier):
      Download here: https://sourceforge.net/projects/gptfdisk/files/gptfdisk/1.0.1/gdisk-binaries/gdisk-efi-1.0.1.zip/download Mount your EFI partition Unzip the file and copy the resulting folder to your EFI Folder, so your path goes like this "/Volumes/EFI/EFI/gdisk-efi" Get into clover configurator, open your standard config.plist from your boot drive and go to the GUI section. Add an entry like this:  
      If you prefer to do a manual config, add this entry to your config.plist, under GUI/Custom/Entries:
      <dict> <key>CustomLogo</key> <false/> <key>Disabled</key> <false/> <key>FullTitle</key> <string>GDisk</string> <key>Hidden</key> <false/> <key>Ignore</key> <false/> <key>Image</key> <string></string> <key>Path</key> <string>\EFI\gdisk-efi\gdisk_x64.efi</string> <key>Type</key> <string>Windows</string> <key>VolumeType</key> <string>Internal</string> </dict> When everything went OK you should see this after selecting the respective entry in Clover:
       

       
       
      3) RU
       
      I recently found one more app that might be interesting to some, and thats "Read Universal" or in short "RU". This is a tool that enables you to debug your BIOS and read (and modify!) every imaginable data, including UEFI variables, ACPI Tables etc.
       
      Warning, again! I think blindly messing around with this app is even more dangerous, but on the other hand it gives you access to a lot of potentially interesting stuff.
      Download here: http://ruexe.blogspot.de/ The next steps are basically the same as above so make a folder in your EFI partition, copy the .EFI files and make another custom entry in your config.plist Here are some screens:
       

       

       

       
       
      So this is what you also can do with UEFI and clover. I am curious which other useful applications might exist!
       
      Anybody who knows, maybe post it here?

      Hello everybody,
      I occasionally have system crashes and suspect that it is related to RAM. However, this RAM is completely new, and a run with MemTest86+ from the USB stick showed no errors. However, if I use Memtest on MacOS, I get a bunch of error messages, but sometimes none (I restart the computer between tests).  
      As I just discovered, my RAM is not on the recommended vendor list of my motherboard, nor is it on the manufacturer side of the RAM. I have read several times that the RAM may not have been tested by the manufacturer on this platform. Not a single X99 motherboard is listed for this RAM.
      So I also suspect that my RAM is not compatible.
      But if that were the case, how could it sometimes work completely error-free?
       
      During RAM tests in summer 2017 (a slightly different setup, 4x8GB but still G.Skill Ripjaws V) I had no errors at Memtest under MacOS, if I remember correctly. At that time it ran under Sierra 10.12.6. AptioMemoryFix.efi could also cause problems.
      I am appreciative for any help!
       
      Here is an excerpt from a faulty test.
      It is noticeable that it is always the same address during the test, but a different one after each test.
