Ok, add Lilu.kext & AppleALC.kext to /EFI/Clover/kexts/Other I see you already have layout-id 13 in your Config file, so try with that. You could also try 3, 17,18 and 28 to see which works best

what audio codec does it have?

@Sepster I was assuming you're already using USBInjectAll.kext when I added the new 10.13.4 port limit patch to your Config file. Anyway, congrats on getting it installed

@kali2000 Your HDEF and HDAU layout-id must be the same. In your DSDT, you have HDEF layout-id 28 whereas HDAU has 12. Change HDAU to 28 or just remove it as advised by Hervé, that should fix it. Hervé, I think you misread, he had to patched port #6(204) to port #7 (306) since as you said port #7 does not exist. With port #7, the HDMI connection works.

Update Lilu.kext and AppleALC.kext. It's been updated with EAPD Fix for audio after wake. With external monitor connected, it's normal for system not to sleep with lid close, you have to select sleep from Apple Menu. As for the screen staying blank, you might have to try injected EDID

@Headshotde The files in Origin folder didn't show it has a discrete graphics card, so you're using the wrong files. Replace the files in /EFI/Clover with the contents from this If you need more help, please open new thread for E7450 with HD 5500 only

Did you add the kexts in LE to /Library/Extensions and then repair permission and rebuild cache?

This one by Rehabman to fix sleep Can you confirm touchpad works on boot and after wake from sleep? Also can you test if adding the (2) I2C Controller patch by Coolstar to Config kextToPatch, you can install VoodooI2C.kext to /L/E without having to remove AppleI2C kexts from /S/L/E

It doesn't matter, I had the GTX disabled via DSDT patch anyway. Optimus don't work on Hacks. Can you post a new screenshot with the new files?

Hmm, according to your DSDT, you're using GPI0 pin 0x0055 Try this DSDT for sleep DSDT.aml.zip

Yes, add to /EFI/Clover/kexts/Other https://github.com/vit9696/Lilu/releases

seems like a graphics issue. Are you running the latest Nvidia kexts? Try adding Lilu.kext & NvidiaGraphicsFixup.kext

Was it there before? If it was, then can change the SMBIOS to MBP11,5 as that's what you had before.

You can google it or get it from here

Try adding 2 new kexts to /EFI/Clover/kexts/Other Lilu.kext & IntelGraphicsDVMTFixup.kext

Try this DSDT, should get you touchpad on boot, but disabled after wake. For audio, disable the AppleHDA patches in the Config file under KextToPatch since you're using AppleALC.kext DSDT.aml.zip

what a mess...here Replace files from here to your /EFI/Clover Install kexts from /EFI/Clover/kexts/Other/LE to /Library/Extensions Remove these from /L/E VoodooTSCSync.kext FakeSMC.kext NullCPUPowerManagement.kext USBInjectAll.kext FakePCIID_XHCIMux.kext FakePCIID_Intel_HDMI_Audio.kext FakePCIID_Intel_HD_Graphics.kext GenericUSBXHCI.kext Remove from /S/L/E USBInjectAll.kext IntelMausiEthernet.kext VoodooPS2Controller.kext VoodooHDA.kext ALC270HDA.kext GenericUSBXHCI.kext Repair permission and rebuild cache Most important, add HFSPlus.efi to /EFI/Clover/drivers64UEFI before reboot or it won't detect your OS X drive or delete VboxHFS from 'Disable Drivers' from the Config file But if you don't want to use my files, then just add the DSDT.aml to /EFI/Clover/ACPI/Patched See if that's enough

No, only disable Legacy Option ROMs, AHCI and UEFI should be enabled.

Have you tried different USB ports? Do you have UEFI/AHCI/Legacy Option ROMs disabled in BIOS?

Give this a try, replace contents into /EFI/Clover 7577_HS_1.4.2.zip

Yes, I'll upload the files once I'm done patching them. What version of BIOS is it running?

Please answer questions from this post including F4 to extract DSDT/SSDT for patching https://osxlatitude.com/forums/topic/10177-dell-7677-kabylake-gtx-1060/?do=findComment&comment=74722

Use this Config https://osxlatitude.com/forums/topic/10187-dell-latitude-7280-tb/?do=findComment&comment=80521

Try replacing VboxHfs-64 with HFSPlus.efi in /EFI/Clover/drivers64UEFI
