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.

IF you want just wireless, DW1510 will work OOTB.

Try replacing all DSDT/SSDT with this. lifeisgood.zip

Ok, looks like you have ALC290, there should be a patched AppleHDA for it somewhere already. Search for Mirone AppleHDA auto patcher. OS X doesn't support Optimus (video switching). If that's what you mean by limitation.

Use whatever theme you like as long as it exists in the Theme folder.

Have you try the bootpack here ? Make sure to replace the VoodooPS2Controller and AppleHDAADT found in the Update guide.

Permission and cache are rebuild successfully but I don't see AppleHDAIDT showing as one of the invalid file. Did you copy it to /Library/Extension?

Launch device manager, then going into the properties of Realtek High Definition Audio. Then click on the Details tab, under Propery, select Hardware Ids, you should see something like this HDAUDIO\FUNC_01&VEN_10EC&DEV_0269&SUBSYS_102.... Discrete Nvidia 940M is not supported, you'll need to go with Intel HD 520, fortunately is supported with 10.11.4. You'll need the discrete card to be disable in the BIOS or with DSDT patching.

Place this in /Library/Extensions. Run this in 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 / Place the output of the commands above here to verify if you have successfully ran them.

Yes

Boot to Clover GUI, hit the spacebar. You'll see a drop down list of option. Select the no cache option.

Replace VoodooPS2Controller with this one. For audio, did you copy AppleHDAIDT to /Library/Extensions and run the permission fix and rebuild cache. If that still fails, reboot without cache, run the permission fix and rebuild cache and reboot once again. If you're on 10.11.4, make sure to use audio kext from the Update section.

@stexano, Do you mean your EFI partition folder is empty? If so, then just copy the Bootpack (Clover Folder & Boot folder) to it.

To determine the ven/prod ID of the Audio from Windows, click on Details. Under Properties, select Hardware Ids. You could do the same for the other devices as well.

Looks like you have the Optimus Nvidia model. The nvidia card is not loading. What bootpack did you use?

If you have only 1 memory stick, make sure it's on the 1st slot.

Remove it from /EFI/clover/Kexts/Other or 10.11
