boot without cache and then repair it

If you're going to be using my bootpack, then do this 1) Download the E7440 boot back zip file. 2) Copy its contents to the EFI/Clover directory on the hidden EFI volume. 3) Download AppleHDA_ALC292 from updated section, place in /EFI/Clover/Kexts/Other/LE 4) Copy all kexts from /EFI/Clover/Kexts/Other/LE to /Library/Extensions 5) Repair permission and rebuild cache, run from terminal sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U /

No, they are not hidden. Perhaps you missed that step to add audio so you might not have it install. You could do a search for AppleHDA and see it shows up. Otherwise just install the ones pertaining to your model from my Update section. The config files from those 2 guides don't have the updated patches for audio, so check my bootpack in post #2 for the patches or replace your bootpacks with mine.

Are you sure the AMD graphics is not disabled? The DSDT is patched to disable it. Try this FB. Backup your original and install this to /S/L/E AppleIntelBDWGraphicsFramebuffer.kext.zip

Can you confirm indeed you do have the DW1520? Get the vend / Prod ID. You can use DPCIManager.app. Google for it.

Looks like you're using Pokenguyen's guide for both Hacks. For E7440, the audio kext = AppleHDAALC.kext For E6430, the audio kext = AppleHDAIDT.kext Both found in /System/Library/Extensions You could do it 2 ways. Either use mine pre-prepared kexts or update them yourself. 1) For E7440, Find in Update section, download AppleHDA_ALC292, rename it to AppleHDAALC and overwrite it in /S/L/E with kextwizard For E6430, download AppleHDA_IDT and rename it to AppleHDAIDT.kext and overwrite it to /S/L/E with kextwizard 2) Follow guide here. Editing the 2 kexts mentioned

Get the updated audio devices here for E7440 and Exx30 here.

You need to keep the vanilla AppleHDA in /S/L/E For 10.11.4, you need the updated AppleHDA_IDT in the Updated section in post #4

Replace the Config in /EFI/Clover with this one and reboot. Added a patch for DW1520 whitelisting (MBP11.1). config.plist.zip

I have a Samsung SSD PM871 M.2. Perhaps it's not supported. AHCI and UEFI were set.

Replace FB in /S/L/E with this one. Repair permission Note: this is for 10.11.4 AppleIntelBDWGraphicsFramebuffer.kext.zip

Don't get ahead of yourself. Try getting the system up and running with graphics acceleration first. Without graphics acceleration, it won't be much of a hack.

Replace in config <dict> <key>Comment</key> <string>EHC1 to EH01</string> <key>Find</key> <data> RUhDMQ== </data> <key>Replace</key> <data> RUgwMQ== </data> </dict> with this <dict> <key>Comment</key> <string>EHCI to EH01</string> <key>Find</key> <data> RUhDSQ== </data> <key>Replace</key> <data> RUgwMQ== </data> </dict>

Enable kext-dev-mode=1 and add booterConfig=0x28 and CsrActiveConfig=0x67 to the config file

try this. Modded Wern's config with USB patches. For HDMI, do you mean video or audio? HDMI video should work with Optimus disabled. config.plist.zip

This is what I mean for Mirone's tool. Select Laptop and alc290. It may or may not work, no guarantee. Brix is one of the small Gigabyte Brix cube system. As for myHack, it helps create an Installer boot disk that supports up to Mavericks, not Yosemite and El Capitan. For the newer OS X, you'll have to manually create the Installer with Clover or Chameleon (enoch branch).

With Wern's Config, are you able to boot to Desktop with the smbios MBP8,2?

Place these in /EFI/Clover/ACPI/Patched. Patched for Graphics, audio, HDMI audio, USB 3.0. Reboot and see if they all work. 3432.zip

Try Wern's Config file

Try restore to original DSDT and see if it still works. You probably have the bypass in the Config file but it'll only work if your cache is working properly. Otherwise you'll have to manually patch the FB.

Try switching smbios to MBA6,2

Try switching smbios to MBA6,2 with Wern's DSDT.

You could try following my Clover guide here, use the Inspiron bootpack 5558 in post #2, but leave out the SSDT/DSDT in /EFI/Clover/ACPI/Patched. Once booted to Clover gui, hit F4, this will export the raw DSDT/SSDT to /EFI/Clover/ACPI/Origin. Compress that folder and upload it here. I'll get them patch for you. Your audio device is ALC255 which is included in the 5558 bootpack, if you're on 10.11.4, make sure to update it with the update version in Update section of the guide below.

add this patch to SSDT-1.aml. See if it will enable HDMI audio. If not, then it could be that HDMI Audio is attached to the AMD device #Maintained by: RehabMan for: Laptop Patches#graphics_Rename-B0D3.txt # for DSDT into method label _WAK code_regex B0D3 replaceall_matched begin HDAU end; into definitionblock code_regex B0D3 replaceall_matched begin HDAU end; # inject "hda-gfx"="onboard-1" into HDAU (B0D3 originally) into method label _DSM parent_adr 0x00030000 remove_entry; into device name_adr 0x00030000 insert begin Method (_DSM, 4, NotSerialized)\n {\n If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n Return (Package()\n {\n "layout-id", Buffer() { 12, 0x00, 0x00, 0x00 },\n "hda-gfx", Buffer() { "onboard-1" },\n })\n }\n end; into device label B0D3 set_label begin HDAU end; into method label SBCB code_regex B0D3 replaceall_matched begin HDAU end;

Your graphics card Intel HD5500 is not loading. You have to either change the DVMT preallocation in the BIOS to 96MB or patch the FB to bypass the check. See my E7450 guide how to change the DVMT.
