Try this config file. I have tested it on an E6430. If you are going to do a rebuild, make sure to use the USB port on the left or the ESATA/USB combo.
Since you already have the system running, you could just install Clover on top.
config.plist.zip
nelight,
what's the display resolution?
1366x768 or 1600x900?
Does it only have HD 4000 or Nvidia NVS5200m as well?
Which OS X are you installing?
10.10.3?
Here you go.
I have include a dummyHDA and use patch on the fly with clover. You'll need to restore the vanilla AppleHDA.
Kexts in SLE folder should be installed to /System/Library/Extensions.
Serial in config has been removed, so generate a new one on your own.
Clover.zip
That guide is a bit outdated.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.
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.
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
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
