DPCIManager actually clearly shows Realtek audio codec ALC235 (10EC:0235). So you need to either patch AppleHDA for ALC235 or install AppleALC + inject correct layout-id. https://github.com/vit9696/AppleALC/wiki/Supported-codecs

A pre-patched version of the AICPUPM kext is provided in the bootpack posted in the guide. It's located in Chameleon/Enoch's usual folder for add-on kexts: /Extra/Extensions. Make sure you've installed that bootpack on your USB installer. Normally, the o.c.B.plist is configured with KernelBooter_kexts parameter set to yes (to load kexts from /E/E) and-f flag (to boot without cache), so you should be able to boot without issues. You may overwrite these by interrupting the Enoch bootloader through F8 when you see the circular character in top left corner of the screen and typing KernelBooter_kexts=Yes -f -v. Thereafter, once you've installed and updated Sierra as/if required to latest version of 10.12.6, you may then install the latest pre-patched version of AICPUPM kext, though I don't believe it's ever evolved throughout the various Sierra updates. You'll find all versions here: I also suggest you set your E6220 BIOS settings as per the recommended settings detailed here: Unlike other computers, my E6220 has all built-in USB2.0 ports fully operationnal without any USB injector kext. Hence absence of such kext in my bootpack.

Laptop with Optimus then... What did you do re: nVidia dGPU?

Looking again at Kali's IOReg, I guess you're right Jake. I just got confused by this: which would not work on the vanilla kext but he's clearly using a non-vanilla one; we don't know what's inside that kext, so even that patch may be useless... I guess it would be most useful to know what the OP's done in terms of graphics and audio kexts mods (replacement and/or patching).

Try removing layout injection from your DSDT HDAU device... I take it that, in your audio PrefPane, you don't have any HDMI audio output that you can switch to, right? This being said: your Clover config shows Azul FB on-the-fly patches whilst, at the same time, your kextcache log shows you're not running on the vanilla Azul FB kext (i.e. you've patched or replaced the vanilla kext). This is highly likely to be incorrect and you should only do one or the other, not both. according to your kextstat log, you appear to be running High Sierra 10.13.4 with Azul FB kext v10.2.5 which is from an older OS X/macOS version... I highly recommend you revert to 10.13.4's vanilla kext (v10.32.48). To be honest, I'm surprised High Sierra loads the Azul Framebebuffer from an older version of the OS. you said you patched ports #6 (0204) and #7 (0306) but you use the expected/correct layout 0x0a260006 for your mobile HD4600. By default, that layout carries no port #7, only ports #0 (0000), #5 (0105) and #6 (0204). When you have HDMI display plugged in, start by identifying the connected iGPU FB/port in IOReg. Once that is done, revisit your Azul FB kext patch according to my patching guide. I could be wrong of course, but I'm ready to bet your HDMI display actually runs off port #5, which is usually the norm. HDMI audio may also depend on the manner in which you get audio working, i.e. patched AppleHDA + dummy codec kext + HDEF layout x or vanilla AppleHDA + AppleALC + HDEF layout y. Let's look at my Haswell/HD4600 Latitude E6440 with ALC292 codec... AppleALC wiki states that, for this codec, the following layouts apply: But if I go the AppleALC route, the results I get are as follows: HDEF layout-id 12 + AppleALC kext + vanilla AppleHDA -> audio Ok but no HDMI audio offered/listed in PrefPane when HDMI TV is plugged in HDEF layout-id 18 + AppleALC kext + vanilla AppleHDA -> audio Ok but no HDMI audio offered/listed in PrefPane when HDMI TV is plugged in HDEF layout-id 28 + AppleALC kext + vanilla AppleHDA -> audio Ok but no HDMI audio offered/listed in PrefPane when HDMI TV is plugged in I will only get HDMI audio output if I run with good old patched AppleHDA: HDEF layout-id 1 + dummy ALC292 kext + patched AppleHDA -> audio Ok, including HDMI audio (offered/listed in Audio PrefPane) NB: HDEF layout-id 1 + vanilla AppleHDA + AppleALC kext -> no audio whatsoever Please note that I still run with Enoch bootloader and no particular parameter in the bootloader for HDMI audio. All I have is the HDEF layout injected in DSDT (with no layout under HDAU device). According to your Clover config, your laptop is fitted with ALC269 audio codec. If you're using the AppleALC method: you may try a different HDEF layout id according to the recommended values: or you may switch back to good old patched AppleHDA (which is my recommendation) Looking at your kextcache/kextstat logs, I could not make it clear how you obtain working audio: I did not see any AppleALC kext nor any dummy kext. All I saw was what appears to be a non-vanilla AppleHDA kext with a version 999-something so I can only assume you run with an AppleHDA kext patched to inject ALC269 layouts. Please clarify all this so that, in turn, we might be of assistance. You've dispersed things all over the place: non-vanilla kexts + on-the-fly kext binary patches, Clover injections + DSDT injections; this makes it really hard to follow... I think you should be Ok running on-the-fly patched AppleHDA (i.e. full vanilla kext in /S/L/E) + dummy ALC269 kext + with HDEF layout-id 1 (as per Toleda's old info posted here). So, set that in your DSDT and remove any audio layout id from your Clover config (you should always avoid duplicating stuff in various places). If things are injected in DSDT, they don't need to be injected in the Clover config too. Unlike kids, computers don't need to be told twice (or more) what to do.

There is no brightness control for this old system under OS X. You can only apply BIOS controlled brightness adjustments through Fn-UP/Fn-DOWN keys. That's the end of it. I would remove whatever change you applied to get the (non-functioning) slider bar in the Display PrefPane. BIOS levels do not get reset on my D630 laptops; make sure you've either applied the AppleRTC patch through Clover or installed a pre-patched kext.

Have you installed the Logitech layouts from the penultimate version of Ukulele?

There's a bug!

If you have space for 2 slots (it seems you do), why don't you opt for a low-profile 1050 instead? Eg: http://www.kfa2.com/kfa2/graphics-card/kfa2-geforce-gtx-1050-ti-oc-lp.html

As a starting point, try this revised Clover config file + revised kexts folder. I've tried to clean up your Clover configuration especially in terms of patches and added some necessary ACPI patches (like the USB devices renaming). Regarding kexts, I've added missing ones and updated existing ones to latest versions whilst reducing them to the bare minimum. We'll add more gradually (like for LAN and other stuff) as necessary. config.plist.zip Other.zip

At this stage, I can only suspect incorrect APN settings.

What does it show when you click on the WWAN icon in the Finder's bar?

Then check that the patch you've used has remained aligned with the plist syntax of 10.13.4's CellPhoneHelper kext. It may have changed and that patch you used was made off an earlier version of High Sierra.

You'll need to remove the VoodooPS2Trackpad kext PlugIn from your ApplePS2Controller kext for the blue TrackPoint to work. You'll lose TouchPad functionalities such as 2-finger scrolling along the way. Failing that, try DrHurt's R4 PS2 controller. I can't remember if TrackPoint worked with it on the D630 (it has V2 ALPS TouchPad). VoodooPS2Controller-R4.kext.zip Re: USB ports, make sure you use MBP7,1 SMBIOS and this kind of USBInjector.

See post #4 here. Fn-F8 does not work under OS X/macOS; that's limited to Windows and possibly Linux.

Means you do not have graphics acceleration because your settings are incorrect.

No reason why you would, must be something else... Make sure you don't use any add-on Atheros kexts like you had initially in your kexts folder.

Cards based on Broadcom BCM4313 chip are unsupported so those go out of the way and other cards based on BCM431x chips were dropped from Sierra; so these are out of the way too. That leaves you with the Atheros cards but you're highly likely to encounter troubles with the AR5B225 because it's poorly supported and so, I don't recommend this at all. Out of the 4 x cards of your list, I could only advise to go for the AR5BHB92, which also happens to work OOB.

Nope, no such issue on mine. Make sure you have generated the proper CPU-related SSDT for power management.

Ha yes, you're right, ripple effect is there when you add an item to the dashboard. And I thought that had been dropped after Snow Leopard!

Did you disable hibernation ?
