Hi all guys :) I need your help and I hope you can help me :)

 
I took the road to install High Sierra on my new build and now I have some doubt / difficulty I do not know how to solve.
 
My configuration:
8700K
Asrock Z370 Professional Gaming i7
AMD RX580 Nitro+ 8GB
 
First I created the usb pendrive and I used Clover with the following configurations:

Bios Setting:
VT-d = Disabled
Share Memory = 128MB
IGPU Multi-Monitor = Enabled
XHCI Hand-off = Enabled
SMBIOS:
iMac18,3
So far no problem, it started successfully, I initialized the hdd in APFS and I ran the installation.

 

Once finished, it started and I made the first configuration successfully. At this point I configured Clover the same way as the installation:

I reboot and start without problems, but I know there is some problem to solve ... for example, the video card seems to recognize it but if I run a benchmark with "Novabench" I noticed that the GPU is recognized as 1GB:
 
With "WhateverGreen.kext" and "RadeonDeInit=Disabled":

I tried to delete "WhateverGreen.kext" and "RadeonDeInit=Enabled" and I recognize the card differently but the same problem presents itself:

Why is it recognized by 1GB instead of 8GB? While on System Profiler is recognized by 8GB .... I'm doing something wrong? :(

 

 

 

I tried to enable also "Hardware Encoding & HEVC Support" but I noticed a detail that I do not know if it's right or not (Hardware Info "MacX Video Converter Pro"):

 
Without "WhateverGreen.kext" and "RadeonDeInit=Enabled":

Is it normal that this occurs? Which one is correct? I'm going completely in confusion :(

 

I'm trying to figure out if I need to make any other changes to the system, if I add some other patches to make it work properly but I do not know where to check.

I'm trying to configure the DSDT but DSDT Editor and MaciASL do not work, they do not open the DSDT.aml file generated by AIDA64.
 
Do you know how to give me a hand? I'm banging my head for 2 days :( I thank you in advance for the help and I apologize for my english :)
 
I hope I was clear :)

Hi,

 

Lilu is needed with WhateverGreen. And you can get ACPI files extracted from Clover by pressing F4 as you boot to Clover. it will be in EFI/Clover/ACPI/Origin. You later patch the DSDT with MaciASL. You might also want to check iOReg for that. However, Mald0n (Moderator on InsanelyMac) tends to happily do it for people. Look up Mald0n on InsanelyMac, and check his thread about CoffeeLake Z370. 

 

 

Good luck.

Lilu is needed with WhateverGreen

But the fact that Novabench recognizes it as 1GB? Why? So it is correct to use Lilu and WhateverGreen for GPU?

And you can get ACPI files extracted from Clover by pressing F4

Once I select the volume to start the mac I have to immediately press F4 (once only)?

 

While regarding Hardware Encoding & HEVC Support "why does Lilu and WhateverGreenrecognize the Intel video card and not AMD?

 

PS: MaciASL it does not work, it gives me an error

The benchmarking softwares might tell you some false or different hardware informations, but that is only cosmetic issues, usually. I know it isn't nice to have it there, but that is how it is. :)

But adding the modified "AML" files, what changes at the end? Can I send files without problems? because I saw that there are many ... what's inside?  :P  :D

But it's really strange because the result of novabench is this: 

CPU: 263 (8700K)

RAM: 292 (16GB 3200)

GPU: 558

 

While on windows the results are much higher, and as if they did not recognize the various components :(

So ... did you ever get this motherboard to work correctly?  I'm looking at getting this exact motherboard and CPU, so I wanted to check.

      Mojave (and maybe High Sierra 10.13.6) on Asrock H370M-ITX/ac and getting RX560 to work with Intel graphics for full hardware acceleration
       
      Components used:
       
      Core i7 8700, UHD 630
      Gigabyte Radeon RX560
      Wifi/BT BCM943602BAED (DW1830) M.2
      Samsung PM961 NVMe SSD
       
      *This guide requires you to know the basics, meaning how to create a macOS install drive, installing and using Clover. There are great beginners guides out there! As always you need at least FakeSMC to boot, every other kext I’ve used is mentioned in the guide. For Mojave beta you need to be enlisted with your Apple-ID in Apple’s beta programme. What is described here may work for High Sierra 10.13.6, but I doubt it to be reliable. Even in early beta status (PB3) Mojave runs much more stable and smoother than High Sierra ever did for me.* 
       
      UEFI-BIOS settings:
       
      The board comes with BIOS version 1.20, there is an update 1.50 on the Asrock website. Usually it is good to stay updated but in this case I’ll recommend to stay on 1.20, because the 1.50 version seems to be unstable and I had restarts upon wake and things like that I couldn’t get fixed even with dsdt patches. So I just downgraded to 1.20 which runs fine.
      Settings needed: Just the usual. Disable fast boot and security boot (everything Windows-related), disable vt-d and enable XHCI hand-off. Activate multi monitor support and set VRAM to 64MB to activate the Intel IGPU. From what I’ve read most people recommend 128MB but I find the 64MB setting to be more reliable, getting artifacts with settings below or above 64MB. 128MB may be needed for 4k support, though. As for nVidia users: You may have to disable the Intel graphics. I’m using an AMD card and that is the brand to go these days since Apple decided to work with AMD
       
      Clover and power management:
       
      I recommend upgrading to 4586. It seems that Aptiomemoryfix is now working with H370 chipsets. I stayed on OsxAptiomemoryfix2 together with Emuvariable and it works. Feel free to experiment.  
      For power management with your CoffeeLake cpu you can just tick plugin type within Clover or compile a ssdt with Pikeralphas script. Mojave reports my cpu correctly as Core i7 since PB3, before that it is just “Unknown” but that is just cosmetic. 
       
      Graphics:
       
      This is the worst part. Getting the Radeon to run correctly alongside the Intel graphics took me weeks to figure out. 
       
      While RX570 and 580 run out of the box in most cases, the RX560 models often do not or at least not correctly. Apple even banned them from eGPU use. For my approach you cannot use “Whatevergreen.kext”, it simply didn’t work for me the way I needed it. Instead I added some fixes to my DSDT to set the correct number of ports used (DP, HDMI, DVI) and tell macOS to use the correct frambuffer. For those who are not into dsdt editing I added my DSDT, look at the “PEGP” section how it is done. This works for the RX560 using the “Acre” framebuffer, you can replace it with “Radeon”, that works too. Other cards need a different framebuffer and a different number of ports. You can do it!   BTW: Do not buy this Gigabytecard!!! It has some weird VBIOS on it, which caused me nightmares before I got the card to work! Buy a Sapphire card instead, they are used by Apple too.   
       
      To get full hardware acceleration for encoding videos you have to have the Intel graphics enabled alongside your AMD card. Problem is, you cannot have it running simply as a second graphics card but you’ll need to “hide” it, means telling macOS that it doesn’t have any display connectors. Otherwise you’ll have screen artifacts or in the worst case just constant crashes. This can be done by adding a certain ig-platform-id in Clover. If you use 59120003 the Intel graphics will not show up in system profiler but it is there. You can check it with iStats or HWMonitor or look if the Kaby Lake graphics kexts are loaded.  This ID makes the CoffeeLake UHD 630 to be recognized as a Kaby Lake gpu that has no display ports, is just used as a helper card.
       
      You’ll need it as a helper card for video encoding. That is what Intel graphics are used for in Macs, to support video encoding on the hardware side. You can check if hardware encoding is supposedly enabled by using MacX Video Converter Pro and VDADecoderChecker. If both say “yes” and “fully supported” this is a good start. But despite the widespread belief this doesn’t mean everything is set correctly! You now have to find out, how to get both cards working together. This is the moment where you have to choose between work and fun: Are you using FinalCut Pro for video editing or are you planning to use iTunes for entertainment? Up until this day (Mojave PB3, High Sierra 10.13.6) you cannot have both working correctly! I’ll show you how it is done both ways. 
       
      The best settings for Final Cut:
       
      Use the DSDT I’ve added with the respective AMD settings for the RX560 or modify them for your graphics card.
       
      Use SMBIOS for iMac17,1 (14,2 does work but picture over DP port is ugly, iMac 18,1/2/3 do not work) in Clover.
       
      Have AppleIntelKBLGraphicsFramebufferInjector_3e9x.kextin your Clover/kexts/Other folder.
       
      Until Mojave PB2 (may work on High Sierra 10.13.6):
       
      Fake-ID 3E928086 plus ig-platform-id 59120003
       
      These are the correct setting when installing Mojave (usually you will start with PB1 as the full installer).
       
      For Mojave PB3 and higher:
       
      Fake-ID 59128086 plus ig-platform-id 59120003
       
      After upgrading to PB3 you will get a black screen with 3E92 fake id because PB3 introduces Coffee Lake kexts and macOS will use these kexts instead but that doesn’t work with our ig-platform-id. So you can download the update to PB3 but before installing it you’ll need to change the fake-id to a usual Kaby Lake id. While this didn’t work in High Sierra and the first two Mojave betas (meaning you didn’t get full hardware encoding) it is now magically working with PB3. It is safe to remove AppleIntelKBLGraphicsFramebufferInjector_3e9x.kext after upgrading to PB3.
       
      The best setting for iTunes and why it is the worstfor Final Cut:
      Just do the same thing as for FinalCut, put Shiki.kext into your Clover/kexts/other folder and add -shikigva boot argument. You can use -shikigva=1 or 2 or 12 it will work either way. Now you can watch movies with iTunes, yay! But it has some sideeffects. You cannot use this setting when seriously editing with Final Cut.
       
      While this works by tricking macOS to use the IntelGraphics to play protected video content, it doesn’t seem to be the way real Macs are doing this. As soon as you open FinalCut you will notice (check this with iStats or HWMonitor) that the Intel graphics is not or only barely utilized, instead cpu usage skyrockets, indicating that slow software rendering is used instead of hardware encoding through Intel graphics. To make it worse the Radeon still “thinks” there is an Intel graphics helping so it does not run at highest potential. You may never notice it when using HD material with 24 or 25p because it still fast enough for that. But 50p or 4k material will most likely cause stuttering. I was astonished when I had stutters while previewing my 50p material, impossible to watch it. Thinking: What is wrong? I have a freaking i7 8700 plus RX560! Even my old hackbook with HD4000 is doing better!     
       
      Wifi and Bluetooth
       
      I swapped the Intel Wifi card that was coming with the mainboard plugged into the onboard M.2 port with a compatible Dell card. The DW1830 or BCM943602BAED. The wifi part runs out of the box, but if you want the card to appear as Apple AirportExtreme and set the country code according to your country you need to put FakePCIID_Broadcom_WiFi.kext into Clover/kexts/other and add some Clover kext-to-patches by PMHeart.

      Bluetooth will work thanks to Rehabman’s kexts. You’ll need BrcmPatchRAM2.kext and BrcmFirmwareData.kext OR BrcmFirmwareRepo.kext. The Data.kext can be injected through Clover, just throw it into the kexts/other folder, the Repo.kext has to be installed in /Library/Extensions on your mac drive, it won’t work with Clover. I had issues with the Data.kext, Bluetooth was gone on every second or third reboot. The Repo.kext is more reliable, haven’t had any issues yet. I really don’t like the kexts to be installed in my system but I guess I have to live with it for the time being.
       
      Oh, handoff and continuity don’t work, doesn’t matter that system profiler shows them as enabled. At least it works in one way: the mac can handoff Safari pages to my iPhone, but not the other way around. Documents opened on my phone show up in the dock, but they are not loaded. 
      This issue is around since at least High Sierra and from what I’ve read Rehabman is not going to fix this, because he founds this features not worth it. I have to disagree, these are very convenient and valuable features if you work with desktop, laptop and tablet in different situations, I miss this capability very much!    
       
      Audio
       
      Audio works with Lilu.kext plus AppleALC.kext and you need to inject Layout ID=1 in Clover. For Mojave use the boot setting -lilubetaall to force the kexts to load. If you like to have DP or HDMI audio add a HDAU device to your dsdt (see mine for reference).

      ho recentemente acquistato un ssd crucial mx500 (arrivato stamattina) e non ho idea di come trasferire il sistema operativo e clover dal mio attuale wd black 500 (2.5" che ho preso da un portatile a caso in casa) su questo nuovo ssd per vedere se questo rende il sistema più reattivo, sul sito crucial dicono solo come copiare i dati e os sul disco ma niente (ovviamente), cosa devo fare per sostituire bootloader, os, programmi e dati su questo nuovo disco? Ho in dualboot win 10 pro (che avvia da un altro 128gb ssd) quindi posso usare anche programmi da win, da una distro linux o da pennetta, non ho usato un granchè osx in quanto l'hdd credo lo renda lento quindi non sono molto esperto in queste cose su osx
      Inoltre mi conviene rimanere su hfs+ o usare apfs come file system?

      I wanted to push watercooling to the most. Silent. Level. possible.
      While gaming and also for working.
      Quite a challenge and a lot to learn.
       
      Thoughts on water-cooling:
      It always depends on the use-case if water-cooling is more silent than air-cooling.
       
      My personal experience:
      Air-cooling is more silent in idle load scenarios (when you just do some easy tasks like browsing or office) Water-cooling is more silent for constant high load (e.g. when you are gaming/working for long times)  
      Tricks to get the water-cooling as silent as possible:
      Configure the BIOS to turn off the radiator-fans in Idle load scenarios. That leaves only the pump running. Undervolt the pump (to e.g. constant 7V).
      This works best, if you can plug the pump into a fan or pump header and assign a constant (lower that 100%) speed to it in the BIOS.
      If your BIOS does not allow that, you could use a resistor-adaptor to slow it down.
