Not sure if I helped but you're welcome anyway. That's weird, sleep and restart causing the speakers to fail to the point of not even being recognised by windows, maybe you should create a new thread with your debug files and explain the problem the best you can there. Someone might be able to...

Hello, I believe you might have to open your laptop and check the speakers, see if they're properly connected and if they already are, you might have to replace them. But in my case I was very fortunate and they just started working again after a few days. BTW: My EFI it's on the debug folder...

Ok, thank you very much for your time and information, I shall repatch my dsdt soon trying to avoid unnecessary patchs. And since I've found the thread problem to be hardware related I'll mark this as solved and work on that.

You mean the DSDT patch, right? To be honest I didn't quite know what I was doing, just followed the patching DSDT/SSDT guide and applied all common patches said to be "commonly needed and that have only a small chance of causing a problem". Do you suggest I re-extract and re-patch my DSDT...

Audio was working fine with latest AppleALC.kext+CodecCommander.kext+SSDT-ALC256.aml.(alcid=56) Then after fixing iMessage for some reason it just doesn't work anymore, I have no outputs/inputs. I tried reinstalling kexts, installing/removing fakepciid_hdmiaudio kext but no luck. Kexts seems to...

Yes, indeed I used Clover Configurator to edit smbios section, didn't know it could mess up with the rest, that was the problem. I edited the original one via PlistEdit Pro and it worked! Thank you very much @RehabMan.

Hello there @missile0407, I'm having some troubles with FaceTime and iMessage, I tried following the "An iDiot's Guide To iMessage" but I'm getting a black screen when I boot after changing serial number and smuuid, I believe the closest macbook model to this laptop is the one in your...

Update: I updated to Mojave and it seems like the problem(glitchy graphics in some applications) is gone. Also seems like graphics are working better now(for example better fps in gaming test). Also, now I'm using 591b along with WhateverGreen, seems to be working flawlessly, I'll mark this as...

Seems like CodecCommander is missing.

I suggest you attach your PR Files.

I just added the following line: "Perform Reset on External Wake", ">n", It works now, but I'm getting high cpu usage after wake, 15- 30% use on idle and constant frequency freezed at 3.1ghz(must be the roof of my processor) new pr files attached

I'm having a problem with audio, everything works fine until the computer sleeps, when it wakes up there's no audio from internal speakers(even though audio control still works and internal speakers still show on sounds). There is a workaround for that, if I plug a headphone it works, and if I...

The KP was because I forgot to enable the 0x591b0000 connector patch(while using 0x59160000 or 0x591e0000 I don't get KP without patch, just don't get HDMI audio). What I noticed is that when I plug in HDMI cable, the connector type on AppleIntelFramebuffer@1(which is my HDMI connector)...

Yes, I also get KP when plug HDMI with 591b, and it didn't solve my problem, 591e also didn't. Done, re-patched acpi, still have the same problem. Are there more platform ids I could test? New PR files attached here.

Thank you very much, it seems I have a problem with my implementation according to this line: kernel: (VoodooI2CHID) VoodooI2CHIDDevice::DELL0782 Warning: Could not get interrupt event source, using polling instead I'll redo my steps and see if I can make it work right. Update: Now it's...

I'm using it on Interrupt mode as far as I know

Thanks. By testing your suggestion of booting into installer without DVMTFixup I figured out that my clover patched/DSDT.aml was causing the problem after changing dvmt-prealloc to 64mb, removed it and I was able to boot, now I'm using yours DSDT and everything seems to be working again(and now...

Ok, I'll try it and update this post I meant to say I couldn't boot not even with the 32mb patch(IntelGraphicsDVMTFixup.kext), so I think it has really changed(at least to something that is not 32mb), I just don't know how to confirm if it has changed to 64mb but I really think it did. Here's...

You mean the missing AppleBacklightInjector.kext? If so I wasn't using it because brightness control worked without so I thought I wouldn't need it, added it now anyway. If I'm wrong just tell me again and I'll search the thread again for the sections I kinda skipped(like nvram and some other)...

Thanks for dvmt patching info. Yet, in my case I got a problem, the computer won't boot after setting dvmt to 0x2. I still can boot on safe mode and recovery. I tried to remove IntelGraphicsDVMTFixup.kext from efi/clover/kexts but no luck. Did you have a similar problem? The last visible text in...
