If you're using AppleALC + Lilu.kext for audio, then you could remove all the AppleHDA patches. Also can remove SecondStagePatch 10.12 patch, as it's noted, it's for 10.12. All AirPortBrcm4360 - PCI Error # can be remove FVCO - wireless 10.12 can be remove as well.

Add this to boot arg abm_firstpolldelay=16000 This is also in my bootpack config, if you're using it. It's a new issue with HS + ACPIBatteryManager.kext.

With latest AppleALC v1.2.2 correct?

Can I assume that that fixed the issue?

Do you have Legacy Option ROMs enabled in the BIOS? Make sure it's Enabled

Built Clover boot disk under Windows http://www.insanelymac.com/forum/topic/288795-guide-creating-os-x-usb-installer-using-a-windows-pc-only/?do=findComment&comment=2012539 You error could be due to bad installer not created successfully. The bootpack attached does not need AppleHDA_ALC293.kext, it's been replaced with AppleALC + Lilu

You have everything you need here including the files in the link

What happened when you use the bootpack with 840m disabled?

Follow instructions from here to debug issue what card are you using for bluetooth?

add FakePCIID_Intel_HDMI_Audio + FakePCIID to /Library/Extensions Repair permission and rebuild cache

HDMI volume control through the connected device, not from the laptop. Displayport should work OOB, but I'll reconfirm on 10.13.x since I last check on 10.12.x APFS.efi is only needed if you're planning on converting from HFS+J to APFS. Not sure what you mean by scrambled graphics after boot. Boots totally fine on my end. Update Clover to v4359, your signature shows 3911, which is really old.

Earlier posts you mentioned you don't have Sierra to install, only El Capitan. So the files I attached is for El Capitan. Brightness won't work with those files if you're on Sierra 10.12.4 and newer. Update with the attached files for Sierra. Replace Config file DSDT + SSDT-PNLF goes to /E/C/ACPI/patched Remove IntelBacklight.kext from /E/C/k/Other Place AppleBacklightInjector.kext to /Library/Extensions Repair permission and rebuild cache Brightness_Sierra.zip

Set BIOS to UEFI, SATA Operations to AHCI, disable secure boot and TPM Follow High Sierra guide here Use attached bootpack Files are fully updated so no changes needed Make sure you have APFS.efi and HFSPlus.efi in /EFI/Clover/drivers64UEFI, can be found in here 3450_A13_HS.zip

That's the one, same name, just re upload with the changes. You just need to replace the DSDT.aml. No other changes.

replace Config and ACPI/Patched You will also need to add HFSPlus.efi to Drivers64UEFI Google it or get it here E7250_A17.zip

Works after sleep / display sleep and connecting / disconnecting from HDMI?

Made a mistake on DSDT, bootpack is now updated. Had HDEF/HDAU layout-id 1 on DSDT and 11 on Config.plist, it's now sync'd. New bootpack uses Lilu + AppleALC for audio Remove AppleHDA_ALC293.kext from /L/E Repair permission and rebuild cache This should fix the HDMI/DP audio If you're going to generate SSDT for MBP12,1, make sure you change SMBIOS in Config file first. Then reboot before generating.

Just need to upgrade Clover to latest and enable FixHeaders in Config file but I don't recommend it. Sierra might be a better choice. With Sierra sleep/wake works, on High Sierra, system reboots on wake. No fix so far if your main graphics is HD 4600. Didn't test with any other cards.

HS guide here using bootpack Kexts in /EFI/Clover/kexts/Other/LE should be moved or copied to /Library/Extensions Then repair permission and rebuild cache.

I might have to repatch your files. Boot to Clover Hit F4. Compress and attach your Clover folder But first try the Sierra Bootpack here

See here regarding wifi We don't support TMX (tonycrapx) stuff here so if you're using it ( unifail/mutifail), then you should ask for support there. Since you're using my files, you should include the kexts folder as well to have audio, graphics, wifi ...working. Kexts in ../kexts/Other/LE should be moved or copy to /Library/Extensions Run permission fix and rebuild cache afterward Dual boot should be supported...

This was mentioned before here

Can't help unless you post the full error. Boot with verbose + debug 0x100 Post screenshot of KP Your signature shows BIOS A13, try upgrading to A17

Ok, if have installed Clover and copied the Clover folder over from your backup, it should work. Or, in BIOS, under Boot sequence->Boot List Option, click Add Boot Option

Try installing Clover as CC does not copy the EFI partition. Another alternative, boot to BIOS, create a new boot option and point it to /EFi/EFI/Clover/CloverX64.efi. Move it to the top of the list.
