Are you using Clover or Enoch branch of Chameleon as boot loader? You could patch the AirPortBrcm4360 with SMBIOS MBP6,2 to load DW1520.

Try different Fn keys to see if Brightness control works. If non works, could be you need to replace your kexts with ElanTouch. USB ports, strange only one works. Have you confirm the other work under windows? Try removing GenericUSBXHCI.kext. Not sure what the issue is with iTunes, seems you have full QE/CI. As for sound after sleep, could be an EAPD issue, try this. You'll need to know the node-ID for this.

Perhaps manually patching the graphics kext rather than using the patch-on-the-fly which requires cache to work.

Did you install clover loader according to this config? Install Clover in the ESP Bootloader/Install boot0af in MBR CloverEFI/CloverEFI 64-bits SATA or Install for UEFI booting only Install Clover in the ESP Drivers64UEFI\OsxAptioFixDrv-64 You should use the 1st, the second is for UEFI BIOS only and this model has some issue and not working right. Make sure to set your BIOS correctly too. Set to 'Load default', apply then set SATA Operations to AHCI. Leave the rest as is.

When you load the EFI partition, does it load from your root/EFI folder or the hidden EFI partition? Make sure it's the hidden partition.

Reason there's no kext folder is because you need to download the E6220 bootpack which contains Config.plist ACPI Kexts Place all these into EFI/Clover folder

Try these, one of the members had these files working. Archive.zip

The problem is your graphics is not loading requiring your BIOS DVMT set to 96MB. Make sure to set Bios Using Graphics UMA only

Try this config config.plist.zip

You place the kexts in the /EFI/Clover/Kexts/Other or 10.11 folder, not OEM

Your battery is not patched properly. Try this DSDT and Config file, make a backup of your first. Added HDMI video/audio patch, AppleHDA on the fly patch and a few other things. Restore the vanilla AppleHDA.kext to /S/L/E and install AppleHDA_VT1802.kext to /S/L/E Repair permission and rebuild cache. B53A.zip

That file is corrupted. Try this. config.plist.zip

I don't have this issue on my Latitudes with IDT audio, only ALC (Realtek). You'll need to patch your DSDT to layout-id=12 (hex=0C)

Try VoodooHDA from this link.

Seems the issue starts after you installed VoodooHDA and disabler. Remove them and see if it'll boot again.

Are you using SmBIOS MacBookPro5,1? Kext is specific to that model D830, so it might not work on yours.

Go to the top of this page, click on EDP. A dropdown menu shows up, select Documentation.

VoodooHDA and AppleHDADisabler needs to be in /S/L/E or /L/E

Enoch is just another branch of Chameleon that will support El Capitan. If you want to switch over to Clover, just install Clover over it and use the clover bootpack.

Try downloading the combo Update and install it that way instead of from the AppStore. It could be a bad download. Yes, SIP is disabled. Kext-dev-mode should already be checked too otherwise you won't have a working Hack.

Strange, 10.11.3 is out, why is it asking you to update to 10.11.2? Have you refresh the screen? Since you're on 10.11.1, you should already have SIP disable.

If you look at the bootpacks in Hervé's link, it's mostly the same for the D620 with Intel Graphics.

Are you installing with Combo update? or Appstore Do you have SIP disabled in your Config file? Kext-dev-mode=Yes?

What issue or error are you encountering? Be more specific. Do you have a bootable OS X USB already created with Clover and a bootpack added? Where is it failing?
