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.

 

BIOS

- the DSDT is based on BIOS v1.46 (whitelist mod or stock)

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

- disable Nvidia

 

Custom Kexts

Mountain Lion (10.8.5)

  • 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 (v3.0.4.1) - Ethernet (gigE) - goes in /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns
  • VoodooPS2Controller.kext (v1.8.x) - 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 (v2.0.2) - 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. 

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

 

   These 5 kexts are the same as in the 10.8 folder

  • FakeSMC.kext
  • AppleIntelE1000e.kext
  • VoodooPS2Controller.kext
  • ACPIBatteryManager.kext
  • ACPIBacklight.kext
  • IOAHCIBlockStorageInjector.kext 
     

   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

  • 2 configuration files (Clover 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 to 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 brightness LCD before sleep - now its the same brightness before and after. 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 10.9 Icon 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 (beyond Clover and manwe150's edits)
  • Added MaxBeepBootVolume to DSDT to rid AppleHDA assertion on startup

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

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

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

     

The DSDT (in OEM folder) has some mods in the IGPU are that remove glitches/hangs on either Clover (or Chameleon.)

 

 

INSTALLATION GUIDE

 

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) install USB
  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) install USB
  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 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)

Hey!

You're looking for feedback from other Thinkpad users. Here I am - proud owner of a X220 :-) I'm currently running 10.7.4 on it and would like to update to ML, but unfortunately all my attempts (clover / chameleon) have not leaded to success. I have the i7 2640M version with usb 3.0.

I followed your guide and can't even completely boot the installer. The GUI is launched (I see a grey screen), but then I get different types of KP... sometimes reboots, sometimes I see a mouse, sometimes not. Really weird. See screenshots of different KPs and logs below.

I have not changed any of the config files you submitted. Anything I could try?

Yes this is a common issue in newer OSX versions and since you are using 10.8.2 you must drop DMAR table or disable VT-d in ThinkPad Setup. (just like in post #46).

Update: Try this striped EFI folder for installing. Updated Clover to r1133, fixed theme selector color, new LAN drivers, new PS2 drivers, new FakeSMC and DualLink=0 by default

Thanks Kogen! Amazing... this had been holding off my ML install for more than a month now!

However, after the install I can still use VT-d, right? Will reinstall wipe applications or will it keep everything? I have some custom kexts installed for Chameleon, but those should get replaced, right? Or would you recommend a complete fresh install (if reinstall is not that anyway).

Thanks again!

Sure You can use VT-d [Enabled] - just remember to downgrade AppleACPIPlatform.kext to the one from ML 10.8.0 or Lion. As for installation, I recommend you make a fresh install and use myHack for your custom kexts (put them in /Extra/Extensions/ and myHack will do the rest). This way you will leave your /S/L/E almost untouched (the only exeption is moving AppleHDA.kext away) + the method will be compatible with chameleon.

Ok, cool, I'll see if I find the time to try this this weekend. If not it will have to wait after my holiday ;-)

Whats the reason of using MyHack vs. Clover's own fsinject to load texts without touching System/Library/Extension? My startup disk is GPT (I also run a windows EFI from another partition), so I guess it is not compatible with Chameleon anyway, or am I wrong here?

1. I have found that some kexts won't work using Clover's fsinject.
2. myHack is clean. It makes only one ID bumped myHack.kext (kexts are loaded first) with plugins folder that includes all kexts you put in /Extra/Extensions (you just have to run myfix -t /)

As for compatibility the difference is that Chameleon does not operate in UEFI, but in BIOS environment. It just fools OSX into believing that it's booting in EFI environment by passing fake EFI runtime services to the system.

Hi there again!

OK, good things first. I bought a Lenovo X220, brand new, heavily discounted since the model is not longer manufactured. Beautiful little thing :)

Specs:
Intel Core i7 2.8
IPS Panel
RAM 4GB
HD 160SSD
Fingerprint, 3G, GPS, USB 3.0 and blah blah blah.

The installation went really smooth, amazingly smooth. The most difficult part shockingly was creating a USB installation disk with Lion DiskMaker. I won't go into much detail, it was a localization problem related to how the Mountain Lion Installation app is named in Spanish making it unrecognizable to DiskMaker. If anyone is interested I can explain him the easy workaround.

Tools I used:

Mountain Lion 10.8.2 installation
The Stripped EFI Folder posted on #63

And I came out nicely and smooth. I even updated Safari and some other stuff without any problems, after being prompted by the App Store app on the dock. I must say the IPS 12.5" looks gorgeous on Mac OS X, much better than on Windows 7 and the system feels faster and more responsive than in Windows, which I honestly find a little bit puzzling.

The system says it's a MacBook Pro 17inch, Early 2011 with a 2.81 Ghz Intel Core i7. The display profile says spdisplays_display 17" (1366x768). Any way to change that? No that it matters much as I said the screen looks terrific.

Working

· Power-On with fingerprint. I stored it previously using the ThinkPad software, since it is a BIOS set up it works independently of the OS. Nice feature.

· Ethernet

· Webcam

· The funny little lamp besides the webcam (Fn+PgUp)

· ExpressCard slot

Working with issues

· Sleep mode works after doing as suggested on post #27. Closing the lid doesn't seem to make the computer enter sleep mode. When the lid passes a certain angle on its way to be closed, the Fn+F4 combination for sleep mode doesn't work either.

· USB 2.0 inputs. USB 3.0 doesn't work, any ideas?

· The trackpad works so-so. Precision of the pointer is smother than in Windows 7 (again I'm puzzled by this), but two finger scrolling works in the opposite direction (if you swipe towards the keyboard the page goes down and vice-versa). Pinch zoom and rotate don't work. Three and four fingers are equivalent to using F11. That's it. Any suggestion is very welcome.

· Battery doesn't show remaining time nearby the icon or percentage. Just on the foldable menu. Anyway to change that?

Not working

· No Wifi obviously. The Dell 1515 card has arrived today though I'm a little bit reluctant to flash the BIOS. Does it void the warranty? Would I be able to return to the original BIOS? Would it be possible to modify the Dell 1515 vendor-ID to bypass the whitelist but still be recognized by Mac OS X as an airport card? It's an appealing approach, though maybe it doesn't make sense what I'm saying... Still thinking about it, is not such a big issue anyway since I can use a wifi nano-usb in the mean time. They're dirt cheap.

· No sound. At all. At first boot the mute and volume keys increased and decreased the bar, now when you press them the volume logo shows up with a forbidden sign. There's no sound card recognized. Any idea where to begin exploring?

· No microphone detected. Is it paired with the sound issue?

· No bluetooth.

· Card reader doesn't work. I think it's a known unsolvable issue so I don't worry much.

Untested

· VGA-out
· Display port
· WAN card for mobile data


Is there any program that kind of "checks" the system to see what is working and what it is detected?

Is there any way to check if the kexts are being applied correctly? I assume they are placed in System/Library/Extensions. Is that correct?

Many years ago with my first hackintosh I remember you had to repair permissions in the Terminal every time you modified the kexts, I understand that now that's done by running myHack, is that so? do you have to reboot afterwards?

I think I messed something up with AppleHDA.kext because I removed the original (kept in on another folder) and placed the one which was on the Extras folder on S/L/E.

Is there any way to stop the messages at startup? I think I read something about line 461 AppleHDA or whatever before entering the desktop.

I haven't touched the dsdt.asml file, should I?

I'm really sorry for the long message, I got carried away :-) Thank you very much for all the job you're doing. It is amazing.

I'm going to gather information and will get back to edit the message if I manage to solve anything.

Regards to everybody!

Yes you can do a Display Override as I did in #13 or use nice little app Tetonne mentioned in #39


Sleep mode works after doing as suggested on post #27. Closing the lid doesn't seem to make the computer enter sleep mode. When the lid passes a certain angle on its way to be closed, the Fn+F4 combination for sleep mode doesn't work either.

For this you need proper dsdt

USB 2.0 inputs. USB 3.0 doesn't work, any ideas?

Search for USB3 kext... I have fount interesting post about AppleUSBXHCI.kext patching for native USB3 support. Since I don't have USB3 - You will be the one to test it out.
To make long story short add this to your clover config:

The trackpad works so-so. Precision of the pointer is smother than in Windows 7 (again I'm puzzled by this), but two finger scrolling works in the opposite direction (if you swipe towards the keyboard the page goes down and vice-versa). Pinch zoom and rotate don't work. Three and four fingers are equivalent to using F11. That's it. Any suggestion is very welcome.

try playing with touchpad and keyboard settings. (we still don't have true multitouch drivers)

· No Wifi obviously. The Dell 1515 card has arrived today though I'm a little bit reluctant to flash the BIOS. Does it void the warranty? Would I be able to return to the original BIOS? Would it be possible to modify the Dell 1515 vendor-ID to bypass the whitelist but still be recognized by Mac OS X as an airport card? It's an appealing approach, though maybe it doesn't make sense what I'm saying... Still thinking about it, is not such a big issue anyway since I can use a wifi nano-usb in the mean time. They're dirt cheap.

· No sound. At all. At first boot the mute and volume keys increased and decreased the bar, now when you press them the volume logo shows up with a forbidden sign. There's no sound card recognized. Any idea where to begin exploring?

· No microphone detected. Is it paired with the sound issue?

· No bluetooth.

· Card reader doesn't work. I think it's a known unsolvable issue so I don't worry much.

Untested

· VGA-out
· Display port
· WAN card for mobile data


Is there any program that kind of "checks" the system to see what is working and what it is detected?

Is there any way to check if the kexts are being applied correctly? I assume they are placed in System/Library/Extensions. Is that correct?

Many years ago with my first hackintosh I remember you had to repair permissions in the Terminal every time you modified the kexts, I understand that now that's done by running myHack, is that so? do you have to reboot afterwards?

I think I messed something up with AppleHDA.kext because I removed the original (kept in on another folder) and placed the one which was on the Extras folder on S/L/E.

Is there any way to stop the messages at startup? I think I read something about line 461 AppleHDA or whatever before entering the desktop.

I haven't touched the dsdt.asml file, should I?

I'm really sorry for the long message, I got carried away :-) Thank you very much for all the job you're doing. It is amazing.

I'm going to gather information and will get back to edit the message if I manage to solve anything.

Regards to everybody!

OK I'm tired ;)

I tried pasting the code you gave me for USB 3.0. I mounted the EFI volume and modified the config.plist file but got a KP on boot. I'm sorry I didn't take any pictures, I'll look through the post you referred to see if I can get it working.

Thanks!!!

I have attached dsdt file for you based on your ACPI dumps.
I recommend you work on your OEM folder now in case of any failure you can always rename it and boot the system from the oryginal striped EFI folder config.

Hello again,

Thanks a lot for your time, it's appreciated. I placed the dsdt file on the OEM folder and run myHack. Nothing changed. So I placed it on ACPI/Patched and it boots to a black screen and this is what I saw before going black:

Attached File  la foto.JPG   197.7KB   18 downloads

Now I try to boot from the USB disk and I also get the black screen and this is the last thing I get to see:

Attached File  booting from usb.jpg   156.98KB   21 downloads

I don't get why it doesn't boot from the USB since it hasn't been mod. Any way to safely start and repair the EFI folder?

Send me to hell if I'm annoying you. I'm trying to figure this out myself but it looks like I lack some basic knowledge :(

By OEM folder I mean (in Your case):
EFI/OEM/42914BG

So your custom dsdt goes to:
EFI/OEM/42914BG/ACPI/patched

And kexts you use goes to
EFI/OEM/42914BG/kexts/10.8/

look inside to see how my old OEM folder looks like.

EFI Shell is much like an good old DOS in use + all the UNIX like commands.
So to get you started find your EFI drive (it is listed on the beginning) and if it's fs0 just type:
fs0:[ENTER]
rest is just like in any normal shell, use commands like: ls, mv, cp, edit, etc.

OK, thanks a lot, I have a better understanding now of the folders hierarchy. I'll go step by step an wont rush to get a hold of what am I actually doing :) I'll report back

I tried many things and finally, with everything clean, after placing your dsdt file and your AppleHDA.kext I got sound, however after reboot it went away, I'm lost here, why would that happen? I reboot several times but sound is again gone for good...

How did you compile that dsdt? I tried with dsdt editor but didn't get any results. I'm trying to learn here ;)

Working with OEM and the shell is so much easy now, just delete the misbehaving file and continue testing, thank you for the advice.

Pasting the code on config.plist for USB 3.0 causes a KP, here's the screen:

Hi, Kogen. First of all, thank you so much for your work. This is my first time using OSX and it's all thank to you! I've been busy these past days with my t420 (OEM 4236) until I finally got it up and running, with sleep, sound, wifi via usb adapter and all!
Well, that was the good part. The bad part is that, due to stubborn nature, I then erased the disk and reinstalled it again from scratch to check whether I had understood or not (I know, I know). As it turns out, I didn't, so I don't have sound at all. I've tried everything, starting with the file you mentioned in post #30, to no avail.

So I turn to you. Attached you'll find my darwin dump; I'd be very grateful if you could take a look and maybe help me.

The missing sound after reboot is strange... wait.
I have totally forgot to mention about the rc scripts files in etc. Attached File  rc.scripts.zip   3.81KB   23 downloads Just place them in /etc reboot and check if this will help (run myFix just in case)

I have used DSDT Editor with the latest iasl compiller (you can search forum for the latest binary or compile one from sources)

Send/Share your config fille - I think something is not right.

From what I see you are not using patched DSDT (I see no modifications) that is why the modified AppleHDA.kext is not working. For this kext to work you need to have Device (HDEF) defined like this in your DSDT:
Spoiler


The easy route for you is to try my DSDT from #21 but remember to edit the DualLink (for LowRes) from 01 to 00.
Good luck.

Thanks! I ended up using raffitaffy's dsdt from post #51 and now I have sound! I will continue poking and will surely come back with more questions! :angel_not:
