Hi all !

 

After months of passive research i have found on some different forums a DSDT solution for disabling the NVidia card.

Disabling Nvidia allow to save battery power of 2x and temperature of laptop too.

DSDT/SSDT Method ( :excl: work on it, not fully fonctionnal :excl: ) : Link here
 
DSDT Method (work with all bootloader)

 

Instructions

Needed 

  • AIDA64 version 2.80 --> link
  • ssdtPRGen.sh --> link
  • AppleIntelCPUPowerManagementInfo.kext --> link
  • MacIASL --> link

 

Disabling NVidia card

  • In the first step, dump your dsdt from Windows with AIDA64 (version 2.80 max) --> tuto YouTube
  • Reboot on OSX
  • This patch don't need to extract or modify any SSDT. You can see the DSDT edits in the link of qwerty12 topic in credits. Quickly, in DSDT, i call external method for disabling the card. These links calls methods of SSDT-4 in my config but can be different with your machine. You don't need to copy manually the _OFF method from SSDT to DSDT. Add these lines if you don't have them to the top of your DSDT :
[...]

External (_SB_.PCI0.PEG0.PEGP._PS3, MethodObj)
External (_SB_.PCI0.PEG0.PEGP._PS0, MethodObj)
External (_SB_.PCI0.PEG0.PEGP._OFF, MethodObj)
External (_SB_.PCI0.PEG0.PEGP._ON, MethodObj)
External (_SB_.PCI0.PEG0.PEGP.SGOF, MethodObj)
External (_SB_.PCI0.PEG0.PEGP.SGON, MethodObj)

[...]
  • I added the method  M_OF before the _WAK method : 
[...]

Method (M_OF, 0, NotSerialized)
    {
        If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._OFF)) 
        { 
            \_SB_.PCI0.PEG0.PEGP._OFF()
        }
        If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS3))
        {
            \_SB_.PCI0.PEG0.PEGP._PS3()
        }
        If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGOF))
        {
            \_SB_.PCI0.PEG0.PEGP.SGOF()
        }
​    }

[...]

 

  • After that, i call the M_OF method in _WAK :
[...]
Method (_WAK, 1, Serialized)
     {
         M_OF ()
         If (LAnd (LEqual (\_SB.PCI0.LPCB.EC0.AAST, One), LEqual (\_SB.PCI0.LPCB.EC0.AAEN, One)))
         {
             Store (Zero, GP53)
[...]
  • And i call the M_OF method in the _INI method :
[...]
Method (_INI, 0, NotSerialized)
         {
             Store (0x07D0, OSYS)
             M_OF ()
             If (CondRefOf (\_OSI, Local0))
             {
                 If (_OSI ("Windows 2001"))
[...]
  •  chameleon.png If you use Chameleon or branch, paste your modified DSDT to your Extra folder and add these options to your org.chameleon.Boot.plist :
<key>DSDT</key>
<string>/Extra/DSDT.aml</string>
<key>DropSSDT</key>
<string>No</string>
  • four-leaf-clover.png If you use Clover Bootloader, copy DSDT file in "EFI/CLOVER/ACPI/Patched"
  • Reboot and go to Applications/Utilities/System Information 
  • Go to Graphics Card Section, if the NVidia Chipset not appear, it’s working.

Enable the SpeedStep management

 

The only problem with this technic is the Power Management. When your turn off the DropSSDT flags in org.chameleon.Boot.plist, Chameleon don’t go dump your SSDT tables in the ACPI tables of your machine.

For enabling SpeedStepper with that fix, you should make a patched SSDT with the ssdtPRGen method :

 

  • Download the later ssdtPRGen.sh
  • Be sure that your SMBios.plist is appropriate with your CPU and system (A good SMBios can fix the iMessage, iCloud, iTunes and Apple Store connexion and login bugs). With my V3-571G core i7, i prefer the Macmini6,2 model for more speed steps.
  • In Terminal app, launch the ssdtPRGen.sh with command :
sudo sh /the_way_of_your_file/ssdtPRGen.sh
  • chameleon.png  Write your password and type "y" when it’s demanded for make a ssdt_pr.aml in your Extra folder only if you use Chameleon bootloader.
  • four-leaf-clover.png  If you use clover, copy this file in "EFI/CLOVER/ACPI/Patched" and rename it to ssdt-1.aml. If you have already a ssdt-1, rename it to ssdt-2... :hyper:
  • Reboot 
  • To be sure that your Speed Stepper is patched, download the AppleIntelCPUPowerManagementInfo.kext and add it to your System/Library/Extensions/ folder with the kext installer of your choice. I for one better in Kext Utility.
  • Rebuild cache with the app of your choice (kext utility make that automaticly) and reboot.
  • At start, open your terminal app and type this command : 
cat /var/log/system.log | grep "AICPUPMI:"
  • If you can see a lot of P-States, you did a good job.

About problems

 

Problem with auto ON after sleep

  • Past this method before the M_OF method in your DSDT :
Method (M_ON, 0, NotSerialized)
{
If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._ON))
{
\_SB_.PCI0.PEG0.PEGP._ON()
}
If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS0))
        {
            \_SB_.PCI0.PEG0.PEGP._PS0()
        }
If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGON))
        {
            \_SB_.PCI0.PEG0.PEGP.SGON()
        }
​ }
  • After that, call M_ON method in _PTS (Prepare To Sleep) so that the _WAK after sleep can shutdown the card. (thanks to RehabMan)
Method (_PTS, 1, NotSerialized)
    {
        M_ON ()
[...]

Error of compilation

 

If you find an error of compilation in MacIASL after have make a clean DSDT (with no error), like "Line 1 : Input file does not appear to be an ASL or data table source file"

 

413958Capturede769cran20140715a768192227

 

 

Try to delete all return to the line in the M_ON or M_OF method or just replace it like that :

 

  • M_OF
Method (M_OF, 0, NotSerialized){If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._OFF)){\_SB_.PCI0.PEG0.PEGP._OFF()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS3)){\_SB_.PCI0.PEG0.PEGP._PS3()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGOF)){\_SB_.PCI0.PEG0.PEGP.SGOF()}}
  • M_ON
Method (M_ON, 0, NotSerialized){If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._ON)){\_SB_.PCI0.PEG0.PEGP._ON()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS0)){\_SB_.PCI0.PEG0.PEGP._PS0()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGON)){\_SB_.PCI0.PEG0.PEGP.SGON()}}

Is it important that I create my DSDT with AIDA64, or can I create my DSDT with DSDT Editor on Mac?

I use Clover v.2330.

DSDT Editor is a good editor but it can only extract the DSDT. AIDA can extract DSDT, SSDT, and all ACPI's tables. 

Can you extract your SSDT tables and upload it here ?

I got some Problems.

 

First is, I don't find the option "ACPI Tools" on Windows 8.1 at the actual AIDA64 Version. But I have found a older Version 3.20.2600 and there ist the option "ACPI Tools".

The Program says that my Motherboard was not found or is Unkown.

 

Second is, that when I use the old Version of AIDA64 in ACPI Tool and click on Save Table I see 7 Lists of SSDT.

Which one you need?

Should I upload all?

 

Here is a Zip with all SSDT 1 to 7 from up to down and the actual DSDT.

Hi guy !

I have opened your DSDT, the first have a bug or is wrong and the second is so buggy ! I try to debbug it but i'm not sure to getting there...

I tell you quickly if i'm able to do it.


Can you upload your DSDT original extracted from AIDA too please ?


Edit : I have found your PS3 and DSM method in SSDT-7, i think that the hack will be functional.

Disassemble them correctly:

# in Terminal, with recent iasl
iasl -da *.bin *.aml
These patches for DSDT:

into method label ADBG replace_content begin //nothing end;
Remove all the lines 'Zero' starting at line ~6258.

 

You then have a DSDT which will compile with no errors.

Yes but this dsdt was modified and have 160 errors. With the original DSDT, it's more simple ^_^

I think it's a bit easier to disable your nvidia optimus in your ssdt ( especially for Haswell ). And you should decompile your dsdt/ssdt through iasl to reduce errors to minimum

P/S: here an example for you, I patched it already, although this Alienware can use the GTX 765M: http://www.insanelymac.com/forum/topic/296713-alienware-17-need-help-with-dsdt-compile-error/

I have no idea how your method works.
In which terminal I need to copy the code?

# in Terminal, with recent iasl
iasl -da *.bin *.aml

I need to use the program MaciASL, DSDT Editor or DSDTSE?

I found this: http://www.osx86.net/files/file/4-iasl-intel-acpi-tools-x64/

Can you post a tutorial or some explanations?

 

At the moment I get about 150 Errors, but I don't use the Code in the Terminal...I don´t know how does it goes... :(

 

THANK YOU GUYS!!

You need to extract all ssdt along with dsdt, only one dsdt is not enough to decompile. Then copy all *.aml and iasl to one folder, run iasl -da *.bin *.aml, the .dsl will have much fewer errors.

hmm, thank you, but I get Kernal Panic... :(

And when I open the DSDT_clean-mo1.aml and compile it, I get 201 Errors...

      Good morning, everyone, I'm sorry if I was wrong in choosing the topic but I need help.
      I have found it extremely difficult to mount a Hackintosh in my acer.
      Setup;
      I5 2430m 2.4 6GB RAM
      Mobo P5we0 - Intel intel Graphics 3000
      At the moment I have not found out what my audio codecs are.
      but I'll leave the link on the motherboard.
      however, my real problem is several.
      I have already used the itakos image, I have already used several images that could be installed normally and that after installing the image I do not have internet via cable or wireless.
      And another, I already looked in other forums and I know that I will be called a donkey in the logical question but I have not been able to install the [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url] or clover to start from the Hard Disk, so I do not know what to do.At the moment I still do not know if there has already been someone who has already installed the High Sierra or just the Sierra in this notebook model and obtained permanent success.
      If anyone can help me, I'll be grateful.
      Installations without success, but with the system already installed in ACER;
      SIERRA
      HIGH SIERRA
      MOJAVE
      All with the same symptom. Starting only by the bootable USB stick and without internet connection via cable and wireless.

      Buongiorno a tutti,
      E la prima volta che scrivo su questo forum, spero di non sbagliare nulla!
      Scrivo qua sperando che qualcuno di voi possa darmi una grossa mano, perchè ho letto di tutto, visto qualsiasi video possibile, ma non riesco proprio ad uscirne fuori.
      Ci avevo già provato 3 anni fa, ma ero riuscito solo su un notebook Sony, sul fisso non ero riuscito a fare nulla. Dicevano che c'erano problemi con i driver della serie Skylake, così ho voluto riprovare ora a distanza di anni.
      Premetto che non sono un informatico, non ho conoscenze particolari. Sono semplicemente un ragazzo che si informa, legge tutorial ed esegue, quindi chissà che la soluzione non sia in realtà una banale sciocchezza.
       
      Dunque, il problema consiste nel fatto che, in circa 8 ore di prove, non sia ancora riuscito ad andare oltre il caricamento del logo, dopo aver selezionato la chiavetta da clover.
      Sto cercando di installare High Sierra, ho provato con una chiavetta con un programma che non ho capito bene perchè, ma non posso scriverlo qui, e una con Clover Configurator (che tra l'altro, nella schermata boot mi da un'interfaccia diversa da quella che ho visto nel tutorial, o anche solo 3 anni prima), ma il problema è sempre lo stesso: dopo circa metà caricamento, o mi esce il simbolo di divieto, o si riavvia il computer, riportandomi nel boot di clover.
      Ho provato un po' di flags, come -v, -x, -s, -f, nv_disable=1 (tra l'altro, per evitare problemi al principio, ho impostato la scheda video di intel come primaria), cpus=1, dart=0, Slide=0, insomma, qualsiasi cosa leggessi in giro che avesse portato esiti positivi, la provavo
      Ho provato su porte sub 3.0, 2.0 e le 2.0 dietro al pc.
      Penso sia irrilevante, ma nel caso, sto usando una chiavetta da 32 gb.

      Nella firma dovrebbero esserci tutte le specifiche del mio PC, non so se debba postare altro. Nel caso scusatemi, ditemi pure cosa manca che la aggiorno.
      Spero davvero che qualcuno di voi possa aiutarmi. Ho un MacBook Air (High Sierra l'ho scaricato da qui) e ho scoperto quanto sia più affidabile usare Final Cut rispetto a quel bug chiamato Premiére Pro che ho usato per anni, e vorrei poterlo usare anche sul fisso, senza dover acquistare un iMac. Ho letto in giro che con Mojave non è supportata l'accelerazione grafica, per questo vorrei installare High Sierra.

      Grazie mille a chiunque vorrà aiutarmi!

      Hello there,
       
      I can't get my soundcard to work on OS X Mojave. Everything else is working. Graphiccard work, LAN work, front camera work, ...
       
      I am on a Laptop:
      Wortmann Terra Mobile 1529H, Clevo W550SU1, 15,6" WXGA (1366x768)
      Intel Haswell HM86 Chipset, Intel Core i5-4210M, Intel HD Graphics 4600
      8GB Samsung DDR3L 1600MHz Ram, Samsung 850 EVO SSD mSATA
      Toshiba SATA HDD, DVD Drive SATA
      Realtek RTL8111 PCI-E LAN Card, Realtek ALC269 Sound Card
      Intel Dual Band Wireless-AC3160 WLAN + BT (removed becouse I don't need it)
      OS X Mojave + Clover (4868) UEFI Boot
       
      Everything else which I can say about my soundcard is:
      Intel Haswell HDA Controller [8086][0C0C]
      Intel Lynx Point HDA Controller [8086][8C20] (probably HDMI sound?)
       
      Codec: Realtek ALC269VB
      Vendor Id: 0x10ec0269
      Subsystem Id: 0x15585455
      Revesion Id: 0x100100
       
      Codec: Intel Haswell HDMI
      Vendor Id: 0x80862807
      Subsystem Id: 0x80860101
      Revesion Id: 0x100000
       
      I have tried several things: Used patched AppleHDA.kext (one time a downloaded, another time I have patched that myself with Apple HDA Patcher 1.9),
      AppleHDA Enabler.kext,
       
      Lilu.kext + AppleALC.kext (but there I don't know how to use them, I have tried to inject with Clover but it doesn't work).
       
      So have anybody an idea to solve that problem (or had solved it already by himself)?
      With Lili.kext and AppleALC.kext do I have to just inject a layout-id or is there more to pay attention?
      In the github page about AppleALC.kext my codec is listet, but with many many layout-id's. I have tried like 30 or so but no solution.
       
      I dont have a audio output device at all in systempreferences. And in systemreport/extensions I see that AppleHDA are not loaded.
      I don't know what to do and hope that anybody could help me.

      Hi guys,
       
      So, this little tutorial is meant to help people fix a new issue with Mojave: opening jpg files (looks like it happens with larger files, not so much with smaller ones) using Quick Look (on spacebar key pressed) or Preview app, using the dedicated GPUs.
      The issue is that, when trying to open jpg files (for some reason, it doesn't occur with pngs), the pop-up window would remain in an endless loop. And from that point forward, any other app trying to open the same file will either become unresponsive (in the case of the Preview app) or just stay in endless loop (in case of Quick Look)
       
      As a workaround, in case the tutorial below doesn't work for you, you can use Grab (built-in app in MacOS) to open said files.
       
      This issue DOES NOT occur using the iGPU. So...if you're comfortable using the iGPU, just switch to that and you should be good to go. You don't need this tutorial.
       
      This tutorial is based on @Cyberdevs' research and testing on this topic (especially useful if you're using an RX series AMD video card), and my own very limited time testing this on my rig. I just thought it would be useful to create a new thread for it so that people can discuss this particular issue here.

       
      With that being said, I'll just move on to the actual tutorial.
       
      New (probably better) method.
       
      Switch your SMBIOS in Clover config in regards to the dedicated GPU you're using, instead of the CPU. Take a look here and choose the corresponding SMBIOS closest to your hardware.
      Yeah, that's it.
       
      In case you lose CPU PM with this method, there are multiple ways to fix that, and they do not make the object of this thread.  It worked perfectly fine for me though and I didn't need to change anything else.
       
      Alternatively, you can also try one of the MacPro SMBIOSes, such as MacPro5,1 or MacPro6,1. It was tested multiple times and it showed good results. 
      Keep in mind that choosing these will most likely not display you an iGPU in System Report, since those machines generally (probably all of them) use Xeon CPUs with no iGPUs either.
       
      A simple Lilu plugin
       
      Thanks to vulgo for the plugin and @Matgen84 for sharing and testing it, we now have yet another possible solution to this issue. It's a Lilu plugin (which means that it requires Lilu.kext in order to work) it's called NoVPAJpeg, and it can be downloaded from here.
      You use it as a regular kext, alongside Lilu. I prefer (and recommend) using it within the EFI folder, in Clover/kexts/Other. But if you want to use it in S/L/E, that should work just fine.
       
      More info can be found in this post here.
       
      In case you wanna try alternative medicine  ...
       
      The main thing we need to do is actually very simple: we need to enable the iGPU (integrated GPU) by default, in BIOS, while actually being connected to the dedicated GPU.
       
      For ATI GPUs (curtesy of @Cyberdevs' post here).
       
      The discreet GPU should be set as primary in BIOS and your displays should be connected to your discreet GPU
      The iGD/iGPU/iGFX must be enabled in BIOS/UEFI as the secondary GPU.
       
      I removed the DSDT Reconfigured the config.plist to and removed some flags which weren't needed because of the DSDT added the InjectATI + Ornioco Framebuffer (I removed the Orinoco framebuffer because of some weird glitches but it might be useful for other AMD GPUs if you inject the correct framebuffer according to your GPU. No need to inject anything for nVidia GPUs unless your GPU needs it) Added the InjectIntel + ig-platform-id for my intel HD530 (for intel HD 530 I use the 0x19120001 ig-platform-id)  
      Steps 5 to 7 might not be necessary I just did them anyway, if anyone succeeded to get quicklook working without those steps let me know so I can exclude those steps.

           Also confirmed to work with AMD R9 270X on a SandyBridge rig (without an iGPU) using WhateverGreen + Lilu kexts, which also helped to solve the transparency issue along with the Quick Look problem, it also resolved the buggy Screen Capture (Command+Shift+5) issue as well. 
       
          Also, do:
      nvram cleanup kextcache & prelinked kernel rebuild reboot  More info on that here.
       
       
      For NVIDIA GPUs
       
      This is what I needed for my NVIDIA rig and the MSI motherboard in the signature. Your milage may vary, depending on your hardware. But, the idea should be the same regardless.
       
         For MSi motherboads (check out my motherboard details in the signature)
       
      Set your BIOS to use PEG (dedicated GPU) so you can boot.
      Since you're reading this, chances are that you're already connected to the dedicated GPU and the BIOS is set to PEG. So just go into BIOS and see if you're using the iGPU or the dedicated (PEG) graphics device by default.
      If you're already using this, skip to Step 3 (the part AFTER Reboot). Reboot (I think you don't necessarily need to boot into the OS...but you do need to reboot at least until Clover UI) Reboot back into BIOS and set it from PEG to IGD (integrated graphics) WITHOUT removing the cable. Save Reboot again.  
         The result should be that the OS is tricked into thinking you're booting with the IGPU when in fact you're using the dedicated GPU.
       
         For Gigabyte motherboards
       
         Set:
      Peripherals -> Initial Display Output -> iGFX Chipset -> Internal Graphics -> Enabled
           DVMT Pre-Allocation -> default 64M.
           DVMT Total Gfx Mem -> default 256M Save Reboot  
         You should do this with the cable connected to the dedicated GPU.
       
      You will also need to patch the iGPU from Clover config.
      1. Graphics -> Inject Intel (UNCHECK Inject Nvidia or ATI if it's checked).
      2. ig-platform-id (in my case for Intel HD 4600 Desktop) it was: 0x0d220003
       
      And use IntelGraphicsFixup.kext (now included into WhateverGreen.kext) in Clover/kexts/Other. In my particular case, without the kext, I would get freezes in Safari.
       
      Another way to activate the iGPU while having the dGPU set as primary is by going into BIOS/SAG/Graphics Configuration/iGPU and setting Multi-Monitor to [Enabled], all the rest remains on [Auto], and set Inject/Intel to [True] in Clover config.*.
       
      Thanks to @gjw for the tip.
       
      *Motherboard dependent. But the multi-monitor option might be the same regardless of manufacturer.
       
       
      This might be a bug with Mojave and it could be fixed by Apple in the future. but in the meantime, feel free to use this if it helps you fix the issue.
       
      For HP motherboards (including laptops), so far no solution, unless the BIOS somehow allows to switch from eGPU to iGPU and vice-versa.
       
      Cheers!
