I installed the El Capitan on a Dell N5010 with Clover. The problem is that I have a low resolution (also runs very laggy) and the video memory shows only 3mb. Some says that with Clover bootloader you can achieve QE/CI on the Mobility Radeon by setting "LoadVBios=Yes" but seems that didn't do trick. Is there anyway to fix this problem ? Card Name : ATI Mobility Radeon HD 5650 (1 GB RAM)

This guide applies to LoRes WXGA (1280x800) and possibly HiRes WXUGA (1920x1200) models. The HiRes model was not tested. This guide was made with ML 10.8(.0) with subsequent update to ML 10.8.3. Contributions/confirmations/issues are welcome on that matter. The bootpack was made out of the D630 nVidia ML bootpack where the DSDT table was just replaced by the table from D830 GMA X3100 Lion bootpack (LoRes). If you have a HiRes model, just replace the DSDT with HiRes version to try it out. Extra_D830_LoRes_ML.zip This guide assumes you're using a blank HDD, partitioned and formated GUID. No tests done on MBR partitioned HDD, so don't ask about it, try it for yourself and report back if appropriate. Read the MacRumors guide thoroughly and follow it to the letter as far as creating the installer is concerned. Basically, if you don't have a legit copy of ML with the "Install Mountain Lion.app" application, forget it. The tool requires you to copy it to your "Applications" folder. It won't work if all you have is the InstallESD.dmg image. http://forums.macrumors.com/showthread.php?t=1325709 Do not ask questions about MLPostFactor here. Go to the authors at MacRumors.

If you have not already done so, remove your myHack USB installer and put it aside. install combo update 10.8.3 (your wireless may not be supported at that stage, so use Ethernet port or install appropriate Wifi kext). reboot into ML 10.8.3, still with default graphics and without acceleration. if you have used myHack 3.2 to install ML, you may encounter KP on EFIRunTime/EFINVRAM at 1st boot. Boot ML via your USB installer bootloader, then download & run Chameleon Wizard and install Chameleon v2248 or later on your ML partition. If you have used myHack 3.1.2, you should be Ok. Phase 2: MLPostFactor download MLPostFactor off the Net (EDIT 28 Mar 2015: sorry, original links posted in 2013 are dead now) create a new small partition on your HDD (8 to 16GB) or insert and erase your myHack USB installer (or any other available external media). following MLPF instructions to the letter, run MLPostFactor and create an ML installer on the freshly created spare HDD partition or freshly erased USB key.

I take no credit for this guide. Hervé and the folks at MacRumors did all the heavy lifting.

Hello , I have a HD4000 and Radeon 7670m on my Samsung Laptop. I would like to activate the hd4000. I add a Chameleon IntelCapriFB=4 and the HD4000 is activated whith 1024mo VRAM and kext loaded (AppleIntelFrameBufferCapri) but no QE/CI . In addition the kexts : IntelSNBGraphicsFB.kext and ApplGraphicsPowerManagement.kext are not load Thanks in advance !!

Dear all experts, For several weeks now I’ve been trying to setup a Samsung NP900X4D-A01ES with dual boot Win7 and ML 10.8.5. I started as a total newbie, with no previous programming backgroung, and I have learnt a lot through the many posts I have read. Finally I managed to install and run ML 10.8.5 with reasonable success. I got wifi working (I bought an USB realtek wifi dongle) BUT no QE/CI support for the HD4000, no power management, no processor optimization, no Fn keys, no sleep/hibernate, no battery indicator, etc….. I soon realized the importance of optimising my system and began to investigate on solving the graphics acceleration issue. Being a noob, you can’t imagine the amount of hours I have spent in this process with no success (except for what I have learnt). It has become an obsession to finally conclude that my lack of in depth knowledge is blocking me to make any step forward. So… I am forced to request the help of the experts here, to whom I am already very grateful for what I have learnt from you. This is what I have worked up to now. As you know the bios of the NP900 series does not allow to set the graphics memory size so I tested every way and every configuration as shown below. 1- I have tried using the key HD4000PlatformId=[0 to 11] with no luck. 2- Then I tried with injecting the bootloader using the key “device-properties†in org.chameleon.Boot.plist with the EFI string I extracted with the help of gfxutil. No luck. 3- Then I though that the only solution was to patch the dsdt.aml directly. So I extracted my dsdt and ssdt files and used DSDT Editor to add the _DSM method under IGPU device. I have tested “AAPL,ig-platform-id†with every combination from 01660000 to 0166000B (except for those with 0162000y and y=5,6,7). No luck either. (by the way, I replaced GFX0 with IGPU and also added the DTGP method at the beginning of the dsdt file. There seems to be no difference in using GFX0 or IGPU). 4- Then checked the dsdt.aml file include in the EDP bootpack for NP900X4C and I realized that the line “AAPL00,DualLink†was not included in my dsdt. I copied it and retried again testing with different values for “AAPL,ig-platform-idâ€. No luck at all; always black screen except for values ending 0A and 0B (screen with clock stopped). However this time I used screen sharing and I could see that ALWAYS, no matter the value of “AAPL,ig-platform-idâ€: a) the OS boots perfectly, no matter what you see in the local screen. AppleIntelHD4000Graphics.kext and AppleIntelFramebufferCapri.kext are loaded, c) System info reports an HD4000; sometimes with a total VRAM=384 Mb, others with VRAM=512 Mb. It depends on the value “AAPL,ig-platform-idâ€. d) System info reports no display attached So… what else can I do? I have read that “in the case of people getting no internal display on some id and ONLY internal display on others, they need to hack an id connector table that contains both the ones displays get detected on.†Well… I’ve been digging in the web but I still don’t know how to do this. Will you pls help? I am attaching my system config files just in case you may need to have a look at them. Any idea that can help me on how to proceed will be very very much appreciated.
