04/21/2015 Update 10.10.3 from 10.10.1

The new update for Yosemite is here 10.10.2. I updated it last night and my graphics card HD4400 (80860a16) doesn’t load. It was lagging, the backlight slider bar was gone. Insanelymac has an article on how to fix this QE/CI lost after the update.

If you have an HP laptop, and use Clover bootloader, make sure you have these lines in the config.plist or you’ll have kernel early panic (reboot instantly), remove the “!”

After the update, we need to patch the 2 kexts that caused the problems: AppleIntelHD5000Graphics.kext and AppleIntelFramebufferAzul.kext by replacing the device ids: 80860412 with our HD4400 device ids 80860a16 both on the info.plist and the binary file. We do need a hex editor app like hexedit that I use to patch the binary.

  1. Hello thank you for your work.
    After the update on 10.10.3 I used your AppleIntelHD5000Graphics.kext / AppleIntelFramebufferAzul.kext, however I the problem that only the Apple Intel frame buffers file functioned. With Apple Intel HD5000 the system falls. Does it already give for 10.10.3 an update?

    Thank you

    1. Sorry, I haven’t updated my Yosemite to 10.10.3 yet so I don’t know how it fails or passes or even have the fix for the failures. When I updated the 10.10.3, I’ll post it here.

      1. many thanks,

        another Question .
        you use which Audio Kext for the Envy 15. I use the VoodooHDA-2.8.7. So far also everything functions, except that those maximally volume is not identical to the Windows variant.
        Can you help me?

      2. edit the the voodoohda.kext info.plist, set the VoodooHDAEnableVolumeChangeFix from “false” to “true” then you can slide the volume to max.
