Use this Config and install this to S/L/E config.plist.zip

You must've be missing something in your Installer. Do you have at least FakeSMC.kext in EFI/Clover/Kexts/10/10 or other?

That guide is a bit outdated. Download Clover Configurator. It's also available in HVT tool in the guide. Open the config.plist with Clover Configurator. On the left side, select Kernel and Kext Patches. On the middle, put a check to "Asus AICPUPM". Click on File and Save.

You have to be more specific. HD4400 or Nvidia? System lagging? No QE/CI?

What graphics card are you having issue with?

What have you got working so far?

There's no MBA 7.2 SMBIOS in Clover, Chameleon or Champlist so far. You'll just have to look for it from a real Mac. As for gfx locking, it seems to run well after 3 or 4 hard reboots. But there's report the El Capitan seems to have resolve this issue. I have install it but unable to get QE/CI on it. Can only boot without Intel injection. The patch to bypass assertion for 10.10.3 no longer works on 10.11 as well.

Got it running with Clover. Did an OS upgrade from Yosemite 10.10.3 Full QE/CI HDMI Video and Audio Internal Speaker/Headphone SD Carder reader DVD Player Not working: Lost Webcam - USB 3.0 issue

Sleep works fine for me with the above updates. Have not been messing with it for the time being until I get the wireless card install. Most things are working, only need HDMI working as the last thing.

Try enabling "HDA Enabler" in Chameleon Wizard. If you installed it to SLE, don't include it in /Extra/Extensions.

Do you have the exact specs as OP? Only have HD4000, no other graphics card? What OS X are you installing? The bootpack posted was for Mavericks, it can be tweak for Yosemite.

You can't update your Installer with a combo update. Download a full Installer 10.9.5 or Yosemite 10.10.3 if you want that from Apple. Use that to create a new Installer.

Could be an issue with your original 10.9 installer. Create a new Installer with 10.9.5 and install over your current build. Data and Apps should be retained.

If you encounter "Can't find /System/Library/Kernel/Kernel" and your Yosemite Installed Drive shows as RAID, do the following: Boot with the USB installer, open up terminal and enter the following command: diskutil cs list you see something like below. Note the UUID in red and Revertible = Yes run diskutil cs revert UUID> , you can copy and paste the UUID reboot when finish. Boot with USB and select your Installed drive to complete your install

At the bottom of Hervé's guide, he mentioned to replace SSDT if you have different CPU...so don't use the included SSDT from his guide. " Other E6420 laptops fitted with same graphics hardware config (GPU + Screen) but different CPU will require a different and suitable SSDT table than provided in the above pack (can be looked up on the web or created with SSDT generator tool -> See RampageDev's blog for detailed guide)."

So you still don't have sound working?

Try removing the SSDT.aml. If that still fails, install NullCPUPowerManagement.kext.

Sounds like it might not be loading your graphics. Please add your systems spec to your signature, that would be helpful for us to assist. Include: CPU, ie i5-2520m GPU, ie HD3000 Display resolution, i.e. 1366x768 Chipset?

What audio kext are you using? Does it show up in preferences and does it autoswitch when you plug in the headset?

What sound card do you have? Most likely IDT 92HD90bxx. See my link below for Exx20_AppleHDA if you're install Mavericks. See Yosemite Guide link for Yosemite version in post #2 of guide.

Are you installing Yosemite or Mavericks? If Yosemite, you need to remove the module FileNVRam.dylib. It will hang at the error you are referring to.

Since you don't need to connect to external display, you can just use the vanilla kext. As I said, just restore it from your Installer with a kext utility.

If you delete AppleIntelSNBGraphicsFB and AppleIntelHD3000Graphics from /S/L/E, then you won't be able to get QE/CI. Those kexts are required. Restore them if you have the backup files or grab them from your Installer.

1st Generation Intel HD is not supported, you won't have a good experience with it even if you are able to successfully install Yosemite. Just remove AppleIntelHDGraphics* from /S*/L*/E* should get you to boot to the installer.

The path should be EFI/Clover/Cloverx64.efi not EFI/Boot/Cloverx64.efi
