example: sudo rm -rf /Volumes/OSX drive/System/Library/Extensions/AppleIntelHDGraphics* Install the patched FB to gain full graphics acceleration. Kexts found in the link posted by Hervé. Lenovo has whitelisted any non Lenovo branded wireless device. In order to replace it, you'll need to mod the BIOS. Google for it, should have one already somewhere, but use at your own risk. Alternatively, use an USB wireless card.

Then try disabling Legacy mode. See if it makes a difference. Don't think it's an MBR or GUID issue. Nvidia definitely is turned off in SSDT-8. Do you have all the DSDT/SSDT in Patched and DropOEM enable in Config?

Enable Legacy mode if it exists in the BIOS.

It might be removed from /S/L/E of the USB installer but during install it's pulling the files from elsewhere. I believe either from BaseSystem.dmg or from Packages folder. Boot with the USB installer, open terminal. run diskutil list to determine the name of the installed drive then remove the kexts from terminal

Yes, IOReg. Strange I didn't change the DSDT/SSDT except added an additional layout-id for HDAU in DSDT. Try booting without cache. Try adding from here for webcam FakePCIID_XHCIMux.kext & FakePCIID.kext

You need to remove AppleIntelGraphics* from the installed drive too.

See here.

Re-enable Nvidia? You mean through the BIOS? Open and save IOReg next time you have it working with the HDMI cable plugged it. Try this config config.plist.zip

Since you're using Clover's hot patches, it's required that you have working cache. Boot without cache mode, repair permission and rebuild cache. Boot normally.

Assuming you're installing 10.11.x Add these to /EFI/Clover/Kexts/10.11 or Other https://bitbucket.org/RehabMan/os-x-fake-pci-id FakePCIID_Broadcom_WiFi.kext FakePCIID https://bitbucket.org/RehabMan/os-x-brcmpatchram BrcmPatchRAM2 BrcmFirmwareData.kext

Copy Config.plist, Kexts folder, DSDT/SSDT from USB to SSD. Don't forget HFSPlus.efi in Driver64UEFI

Are you sure about your screen resolution? LCD: 1600 x 900 in post#1. Your original Config.plist shows you are using singleLink in your patching. I changed it to DualLink from info from your 1st post. Another cause of artifacts is due to BIOS version. Did you downgrade your BIOS from something higher than A12? It's know to cause artifacts for Dell Latitude HD4000. You need to downgrade to A03 and then back to A12 and not higher.

Check Config.plist. Make sure nv_disable=1 is uncheck

Add this to /Library/Extensions and repair permission and rebuild cache sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo kextcache -Boot -U / E5430.zip

Did you include both CodecCommander & EAPDfix? Yes, I know they both do the same thing, but each alone does work as well as both together for this particular codec.

Boot to Clover, hit F4. Then boot to OS X. Compress and send me the whole Clover folder. Launch IORegistryExplorer_v2.1.zip ,save and upload that as well.

Replace DSDT with this one 5558_HD5500_v4.zip

Check, make sure the DIMM is in slot 1 if you only have 1 stick.

try this. Make sure Optimus is uncheck config.plist.zip

Do you have AHCI set in the BIOS?

add this to /EFI/Clover/Kexts/Other. See if it'll enable the webcam. On your Windows, can you disable the Nvidia card and see if HDMI audio works?

What error are you encountering? Did Clover load? Try booting without cache and Post a screenshot.

You don't hear sound from the monitor when you increase the volume? Can you try on a TV? Please attach IOReg

HDMI audio is control by the monitor or TV, not from the PC Try this config, see if webcam shows up in the USB ports config.plist.zip

Try this config.plist.zip
