Lenovo ThinkPad T420 with UEFI Only

tluck · December 29, 2014

@mircsisz

do you have old zip version and log before 3094 - i.e. when it used to work?

where was it getting this before you switched to use a custom entry method?

Custom entry 0 FullTitle:"Windows 8.1" Path:"/EFI/WINDOWS/Boot/bootmgr.efi" Options:"-s -h" Type:7 Flags:0x0 matching all volumes

also not sure about win 8 but the windows boot manager for me (win 7) is bootmgfw.efi not bootmgr.efi.

have you tried my config.plist?

mircsicz · December 29, 2014

@tluck I don't have boot.log from older boot's but just created some, think I've most versions since 2967...

Here's the config I use:

Except from DefaultVolume, Timeout and MLB&ROM it's your config1600x900.plist. It's the one that worked for me from the beginning of my OSx86 Setup on my T420s...

Here's the 2967 boot.log

2988 boot.log

and 3097 boot.log

All tested with the config.plist from above...

tluck · December 30, 2014

mircsizc

well that must be an older config.plist - but the output looks different - and ok. no weird stuff around custom entries. so remove the hide windows thing or get the latest config.plist and you should be seeing all your bootable partitions.

dauren · December 30, 2014

Hello, I'm happily running my hackintosh for over a month now and finally decided to add a second display, Dell 2414H. I'm using DP-DP connection and OS doesn't see the display.
I'm running 1600x900 plist with HD3000 only enabled, OSX 10.10.1. and Clover v3025. What should I check?

tluck · December 30, 2014

@all - i reposted a new bundle with clover r3108 - the change is I recompiled it to remove (annoying) text before the GUI.

@dauren - hmm not sure. you should have DP buffer/port available? are you using the zip/config.plist from my guide?

can it find it on cold boot up?

if you look at the kexts do you see these kexts

$ kextstat|grep -i grap

77 15 0xffffff7f812ea000 0x47000 0x47000 com.apple.iokit.IOGraphicsFamily (2.4.1) <12 7 5 4 3 1>

119 1 0xffffff7f81ff0000 0x6000 0x6000 com.apple.AppleGraphicsDeviceControl (3.7.21) <7 6 5 4 3 1>

you could dump out registry (run: ioreg -l) and and there should be 4 frame buffers. this with LCD and external monitor on my DP (left side).

I have followed this guide 100%, but my audio is not working.

Everything else is working.. What am I missing?

I have a t420 with Conexant 20672.

Is there something extra I am meant to do that isnt in the guide?

the expert is tluck but i would add again all the kext in /S/L/E

use Kext Utility again

reboot

it shoud work

Happy new year to all

tluck · January 1, 2015

@dreddtech

welcome to the club!

key factors for the AppleHDA_20672.kext:

is that the file Contents/MacOS/AppleHDA is symbolic link to the native binary.

which means you keep the original version in place.

you can check that from the command line.

and the kext must be installed in /S/L/E versus left in the /EFI partition.

$ cd /System/Library/Extensions/AppleHDA_20672.kext/Contents/MacOS

$ ls -l

total 8

lrwxr-xr-x 1 root wheel 64 Dec 24 16:50 AppleHDA -> /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA

Just to confirm,

I am meant to copy all the kexts you provided to S/L/E then run them through kext utility?

Do I still keep them in the clover folder?

tluck · January 2, 2015

yes. to make a copy in /S/L/E drag them all onto the Kext Utility. (refer to the post OS install section of the guide)

walid-wah · January 2, 2015

I did all the steps and everything work perfectly! but what about the wifi?

Is there anyway to get the wifi working or i must use external wifi adapter?

dreddtech · January 2, 2015

Ok so my audio still isn't working.. But after running that cmd you advised tluck it looks like the symbolic link isnt working. What would cause this?

tluck · January 3, 2015

@walid-wah

the built-in intel wifi will not work. you need to replace it with a OSX-compatible chip/card. there are a number of broadcom or atheros options. or you can get a USB version.

@dreddtech

well you can make a new symbolic link and then rebuild the caches. do this:

cd /System/Library/Extensions/AppleHDA_20672.kext/Contents/MacOS
sudo rm AppleHDA
sudo ln -s /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA
sudo touch /System/Library/Extensions

dreddtech · January 3, 2015

Sound is now working

Cheers tluck.

Hello everyone,

One more T420 user here, trying to make it to run Yosemite as the primary and maybe the only OS.

My model is 4236AT9 which is the same as tluck's (btw THANKS MAN for your amazing work here!!! This is an example of dedication and community support for all of us!).

Given the above, I hoped for an easy walkthrough, but guess what... kicking the tires for the 3rd day already. May I ask for some help?

I believe the cause of my pain is that I only have access to old MacMini running Snow Leo (10.6.8), though probably my lame hands and lack of expertise exacerbate that ;-)

Long story short... I transferred a 10.10 image to my Mac Mini, createinstallmedia failed with "incorrect CPU type" error (which didn't surprise me), but unfortunately Clover_v2_r1625.pkg failed as well.

Fortunately, a Mountain Lion Install Disk Build Tool (found in another thread here) supports Yosemite now, so I was able to run it on my Snow Leo.

And Clover_v2k_r3113.pkg works as well, though I am not sure if I need to use it on Yosemite install disk prepared with above tool...

I followed the guide where I could (upgraded BIOS, switched to UEFI, disabled virtualization, put the contents of T420/EFI dir to manually mounted ESP of USB partition, renamed ACPI.1600x900 to ACPI, etc... Here is where things stand now:

The USB boots to Clover in UEFI mode, there's a ThinkPad theme, and I can get to options and shell and such, but when I kick "Boot Mac OS X from Yosemite Install Disk - 10.10", I get an apple logo for like 25 sec., and then the laptop reboots.

My semi-educated guess is that I need to put some pieces in place, that are normally put by either Clover_v2_r1625.pkg or createinstallmedia.

Can I still get through without running these two?

Thanks,

Me.

Update: I followed this guide to manually create install image. So maybe my question is just about where to put the remaining kexts, DSDTs, AMLs and other small pieces that I have very vague understanding of.

Or, to realize that I am heading in a totally wrong direction.

@dauren -

no idea - does this same cable work with windows to the external monitor?

so you still struggling with making the Yosemite installer?

I presume you have downloaded a proper Yosemite version (installer) from AppStore? so you have /Applications/Install OS X Yosemite.app

for 10.10.1 it will installer version 1.6.7

I take it that you cannot use the built-in (creatinstallmedia) method because the macMini is not yosemite compatible?

then perhaps try the more recent version of Lion Disk maker. http://diskmakerx.com - which is yosemite capable and can run on 10.6.8.

once you get the bits onto the USB (format the USB GUID/GPT formatted) then you can replace the /EFI partition with the same zip.

the Diskmaker process will erase the disk and put all the installation bits onto the 2nd partition.

once this is done, follow my guide at Part 1 installation common steps.

Thanks for chiming in! Sorry, yes, still there... And yes, I used the same latest Disk Maker X 4b4, rebooted/re-ran again, now in the end of the build process I noticed an error (attaching screen)...

Now checked the FAQ section on diskmakerx and found the following:

I can’t use DiskMaker X with Mac OS X 10.6.x if I try to use it with my Mavericks installer!

Because of a bug (or a feature?) in Apple’s built-in command createinstallmedia with 10.6.X, DiskMaker X is not compatible with versions of OS X prior to 10.7. I’m working on a fix, but it may take some time to make it available as it means using another completely different method.

So now I am not even sure if it supposed to work on my MacMini, even though it launches and does the job for the most part (or so it looks like).

Regardless... Is there a way to validate my newly built install disk, at least for most common user/environment errors?

Or to collect some info on what's going on before ThinkPad reboots trying to launch the installer - like enable diag output instead of apple logo?

In lieu of better options, attaching the filelists from this USB. Maybe something looks not as expected and can be fixed by simple file manipulation?

MyUSB-AllFiles.zip

Truth be told, I have quite marginal Mac exposure (hope to make it better with this exercise), and my Win / Linux experience is almost 10 years behind the time, so the gut feeling is I may be missing something so trivial that it's not even mentioned. Like... should I have created partitions on the USB stick, after switching to GPT? Especially keeping in mind case sensitive filesystem or otherwise? Can existing HDD layout on the T420 be a problem? (I didn't kill a few Linux partitions there yet).

Thanks again,

Me

things seem to be pretty much as they should be from the USB standpoint.

when you boot up and land on the Clover GUI, you can hit the space bar to then boot with options. boot the OSX Installer with verbose to see where it goes. or stops. it may take 5 minutes or so boot up.

However, there is alternate manual way to make an installer from OSX - i just tested on Yosemite 10.10.1 and it worked just fine.

on your Mac mini...

1) format an 8GB USB as GUID with 1 partition HFS - which makes EFI partition as well.

2) follow the "dev method' in this link: this guide

Note: I renamed the USB copy of "OS X Base System" to "Installer" (to make it more obvious in Clover) when it finished copying everything to it.

3) mount the ESP and then copy the zip contents - the full EFI folder set to the ESP.

4) rename ACPI.1600x900 to ACPI

5) rename config.1600x900.plist to config.plist

then reboot and hit F12 to select boot from USB

select Installer - you can hit space to boot verbose - but otherwise the Installer booted for me.

Hey everybody,

trying to install Windows 7 on my t420 from a DVD I created by downloading the Windows 7 installer.

Strangly the installer tells me that I can't install on a particular partition because it's MBR, but it is GUID in fact.

I want to install on disk1s4 partition. Any ideas?

Thanks, juniorprofi

Re-make your win7 installation using Rufus. Select gpt for uefi computers when making it. Make sure your Iso is 64bit. And you may have issues if the image is x86 x64 multi

if you created the NTFS partition with Disk Utility it will have converted your GUID disk with a PMBR to one with MBR. this confuses the windows installer. search this forum for PMBR - i have gone over this many times!

Note: i suppose i will add it the GUIDE - of what NOT to do - when dual booting windows. gdisk can fix this - i.e. get rid of the MBR.

Here is a script I used recently to clone my HD when it was failing. the script makes 4 partitions.

EFI

OSX

Recovery HD

Windows (NTFS)

you can decide how big to make your OSX vs Windows partitions but this was on a 750GB drive. it is roughly a ~48GiB windows partition. see list at the end. if one already has the first 3 sections and there is enough space on the disk (or one can shrink the OSX and add free space if needed) then one can use the partition 4 section below to add a Windows partition that is UEFI/hackintosh compatible.

the script is meant to be run as root:

save the lines below into a file for example make_disk.bash

edit all the size parameters to match your case

suppose disk1 is the one you want to (re)partition

then run by: sudo make_disk.bash disk1

if you want to just add a 4th partition then put the section 4 in a script (and fix the sizes)

#!/bin/bash

# use gtp to add windows partition - to keep PMBR

# partition 1  EFI
diskutil unmountDisk $1

Thanks for your efforts, but sorry, no cigar - I am still stuck in mud, kicking tires, slamming doors and flashing the headlights. And the idea of voodoo dances doesn't seem too weird already...

The dev method you referred to is exactly what I did last time, so now I tried to do better and rule out a few 'suspects' with the following:

- I found someone with a Mac (Lion) who allowed me to play on their system a little bit, so I could re-download Yosemite from the app store, and run the creatinstallmedia in a standard/easy way (command line).

- And I tried to boot the installer in all different modes, thanks to your hint (verbose, single user, safe, no cache/kexts etc), but with exactly same result: machine goes to reboot in a few seconds (or immediately, depend on option selected), after local hard drive is detected. Or so I interpret the output, see picture attached.

- To rule out anything HDD related, I swapped it with a 25GB drive from some ancient ThinkPad. This drive has just one empty NTFS partition. I can even zero it out, if that can make a difference.

Still no progress, but now once we have installer and HDD 'cleared', the next suspects are hardware/firmware guts, nuts and bolts, correct?

This laptop was used to run various Linuxes before, and I just confirmed it boots to Windows 8 PE x32 and x64 live CD (this is how I flashed the BIOS). I don't see reason to suspect odd ACPI config, or faulty hardware, or custom flashing. The machine is not secured/locked in any way that I could identify, no system/disk passwords etc.

So, can we confirm these two things:

1. Should I have unpacked all contents of T420_UEFI-Clover-b3108_10.9_10.10_2014-12-30.zip to ESP-USB partition completely, or just EFI directory, as I did (renaming two 1600x900 items of course)?
(for example, this ":System:Library:Displays:Overrides/" directory looks quite fancy, never seen anything like that... No need for it to be on USB? Just curious...)

2. I upgraded the BIOS to "stock" 1.46 as your guide suggests, but did not flash the whitelisted one (the link in patchers' forum is broken, and I didn't find another copy - maybe someone here has it), and same about DSDT and such, I didn't do anything like that. Could it make a difference?

That's what I could think of and try at the moment. Knowing that we have 100% identical machines makes this situation look a bit crazy. What could I possibly do wrong there???

Thx,

Me

@OneMore.

well you have made the installer. and added the entire EFI folder (just need the EFI folder for the USB) onto the ESP. that's done.

and it looks like its trying to load from the USB. what size USB is this? did you try different USB ports?

very odd as you say. we have the same system. it must be a system BIOS setting. you have v1.46 so good. did you reset to defaults?

BIOS settings:

- disable VT-d

- SATA set AHCI mode

- Enable Execution Bit

OneMore · January 6, 2015

@tluck

Yes, I tried all 4 USB ports.

The flash is PNY 8Gb, never had problems with it.

VT-d disabled, Virtualization enabled, SATA set to AHCI, everything else reset to defaults multiple times.

Execution bit... I do not see this language in BIOS setup, do you mean Security / Memory Protection / Execution Prevention? This is set to "disabled" (default) which I believe is the same meaning.

Do you have patched / un-whitelisted BIOS 1.46?

Thx,

Me
