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

Working now without KP, only sound is gone. What did you modify on it? Rest works great without KP's now!

[Kogen Mantis]

Yes sorry... forgot about the sound is using codec ID 12 now, cause I'm testing other AppleHDA driver found in this post.
HPET is fixed by adding IRQ's 0,8,11 and 15

Here's a screenshot uploaded from my T420.
Used your latest dsdt from post #21 (for anyone having same issues ) working great now!

@Kogen Mantis, you're doing a great job here, thanks very much for the work you have done and what you're doing! Even sleep is working etc etc!

[distortionmusic]

After a day i use I notice that sometimes when I close the lid, it doesn't go to sleep but freezes with a black screen and a flashing sleep indicator. Do you have that as well or would that be specific to my model Thinkpad and it's DSDT now?

I'm doing so many test with different types of setup and configurations that I've didn't noticed that... I mean sleep doesn't work as expected sometimes but I was always blaming  something else than the DSDT. I guess I should look closer into it.
What UEFI Bios version you are at now? And can you write down the steps to reproduce the sleep problem.
Also I have hibernatemode disabled:

sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage

I use the original 1.43 bios now.

How does your system run now then? I am running OSX only now, and I use it for school every day (Yeah it's a bit tricky but it does work much better then Windows).


EDIT: disable hibernate works really well, it goes to sleep faster (immediately) and it wakes up with the same speed as well!

Can you tell me how your testing with the other sound kext is going? I can't get it to work yet, I've read trough the tread but I'm not much wiser yet haha.

I can confirm that everything that worked before update keeps working after update to 10.8.2 btw. It runs really stable and fast, much better then with chameleon and non-efi use.

Joke is, that with the use of EFI, you really get all the "toys" you have with a real mac. Like you mentioned in your first post. Even Bootcamp seems to be working.

In general I'm very happy about the result, but there are few little things that are still bugging me.
- brightness is lower than default (i use bottom-right corner to put display to sleep and wake it up for better brightness)
- SD card reader not working (though I use the pci-express to SD-card adapter)
- it would be nice to have a better mouse driver

Yeah indeed. Brightness is not really an issue in my case, because I use mine for school. Which means, I use lower brightness anyway for longer battery life, but I put it to sleep every now and then as well.
I was searching the net for a possibility to use multitouch like the newer MacBooks have (three finger window switching etc), would be great it there just was sectretly hidden button to turn multitouch options in prefpane for touchpad...

can you tell what you have done to make sound kexts from the project you mentioned? I didn't get the way he got it to work.

I always install new kexts by /Extra/Extensions/ using myHack | myFix so just put the patched AppleHDA.kext in there and move the original one from /L/S/E

sudo mv /System/Library/Extensions/AppleHDA.kext /System/

and run myFix (Quick mode)

[Anthony C]

So I got ML installed and ran the myHack however I have no sound or network. I'm trying to learn how to generate a DSDT but haven't been successful yet. Do I need to reinstall?


machine type: 4179w1f



Thanks....

No there's no point for reinstalling. Beside the HD (Low resolution) screen you have basically thesame hardware specs like I do. So again... rename the 4180A32 folder inside EFI/OEM/ to 4179W1F and use this dsdt:  dsdt-143001.zip 25.91K 70 downloads but change the DualLink to 0:

"AAPL00,DualLink",
Buffer (0x04)
{
0x00, 0x00, 0x00, 0x00
},

place the edited dsdt file in

EFI/OEM/4179W1F/ACPI/patched/

As for sound driver read post #30

[seraph1024]

I am doing this on my Lenovo T420 (Type 4178-6WU) with SN R8-Y2BLZ. I have tried different DSDT files as well. I keep getting hung on ACPI_SMC_PlatformPlugin::InitFanThrottleControl - Waiting for AppleSMC
What else am i missing. I am using a FAT32 USB with CLOVER2 and your EFI update from the first post.

Looks like FakeSMC.kext is not loading ... make sure you have it in:
EFI/kexts/10.8/ or in case you renamed my folder to your model name in OEM/41786WU/kexts/10.8/

Thanks for the quick reply. Same issue even with FakeSMC in both folders.  I do have dual video cards on this verison. Could that be the issue?

[seraph1024]

Well, after moving things around, it is now going in a loop.

The more information you give the better chance to resolve your issue.
- what OSX version you are trying to boot?

Update: Try disabling OEM table DMAR in Clover option during boot and report back

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.

Yes I'm using Clover r1062 cause latest builds broke cpu detection (thus I get fuzzy sound) and graphics are messed up.
BTW1: what is the DeviceProperities string injection good for?
BTW2: whats your full serial number and hows is your CPU detected in 1050? (Is it 2.6GHz or 2.59GHz)

Nice little app for beginners that just want to add the "Display LCD" for the unknown panel. Thanks for bringing this up.
