HD4000 not working on a Lenovo T430u

[M1___M1]

Hi everyone
I’m new in hackintosh, but I manage to install ML on a Lenovo T430u. The install is in dual boot on the same drive as win7 on a MBR partition
What is working:

• Video with GraphicsEnabler=No (HD4000 not working yet)
• Audio (VoodooHDA) –
• Camera (native)
• Keyboard, trackpad (VoodooPS2+ThinkpadUltraNav)
• USB ports (most of the time)
• LAN interface (Realtek – lnx2mac)
• Bluetooth (native)

What is not working:

• Wifi: I use a wifi usb instead
• Trackpoint
• Sd card reader
• HD4000 has no Kext loaded, not recognized for the system
• USB sometime PC freeze when plugging a usb stick

My main concern is the HD4000 (no Kext loaded), so I cannot play video or use aperture and the HDMI port is not working as well.
I tried several things to fix it:
Using multibeast 5.2.1: option Intel Graphics Patch for mixed config + bootloader chimera 1.11 (didn’t work)
Installing Chimera 1.11 and follow the instruction of ( http://www.-- PIRACY PROMOTING SITE m --/2012/07/intel-hd-4000-hackintosh.html ):it is supposed to manage HD4000 but didn’t work. (By the way there is no setting for video card memory in Lenovo T430u Bios). So I assume it is fixed to 64 Mb.
I insert in org.chameleon.plist

<key>HD4000PlatformId</key>
<string>9</string>

Also tried with <string>8</string>

Here is my actual org.chameleon.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<key>Graphics Mode</key>
<string>"1920x1080x32"</string>
<key>HD4000PlatformId</key>
<string>9</string>
</dict>
</plist>

Any idea how to fix the HD4000? it would be greatly appreciate.
my english is a bit approximate as it is not my native language (I'm from Reunion island).

(By the way there is no setting for video card memory in Lenovo T430u Bios). So I assume it is fixed to 64 Mb.

This could well be your problem.. how about confirming the video memory.. if its 128mb then you are screwed.... as far as I can see

I had exactly the same problem..

I solved removing these lines from org.chameleon.Boot.plist

<key>HD4000PlatformId</key>
<string>9</string>

and adding these lines:

<key>device-properties</key>
<string>5e0000000100000001000000520000000100000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601</string>

Thanks marko93b for the info...the device-properties string also works on the acer v5-171 (the i5 model) as well...its video ram is locked @128mb on the Insydeh20 bios page...! IntelHD4000 is identified in the system properties with 384mb, and QE/CI works...!

thank you very much for your answer.

i tried removing HD4000 platform and adding the device properties, but screen freeze at start. i can only restart in safe mode (not every time)

how did you figure out the string of your Device property?

thank in advance

I found that string on the internet (idk where) but i think you can extract your string using gfxutil.

Is there any reason why you can't use the PCIRootUID=0 flag when booting up? I am not entirely certain of the ramifications, but I needed to do this on another system last week, and when I saw this post, I decided to try my T430U.

I was able to get full HD4000 graphics, 512MB RAM detected by enabling this on boot. I also noticed (and perhaps it is because I have not yet loaded any kexts) that my pointer stick and buttons are working as well.

I did not mess with any other settings, just the above.

HTH

EDIT : I tried applying the 10.8.3 update (from 10.8.2) and it seemed like it hung on me. Did that to me last week on a gigabyte board. Not sure what that is, but am reinstalling my laptop now, and with the PCIRootUID=0 set on the install screen, the graphics are working and so is the trackpad/trackpoint. Interesting!
