Disabling NVIDIA Optimus card on all laptops

gee thanks  <_<

 

What I meant is, why is it not possible to call method SGOF directly from the DSDT using "External (_SB_.PCI0.PEG0.PEGP.SGOF, MethodObj)" as per your guide? Why do I have to copy all those methods from SSDT to DSDT?

 

Yes, it's possible but why make that ?

please help me i don't know how to fix!

 

attached my dsdt from aida and my ssdt! thank you :)

 

You don't have attached the originaly DSDT and SSDT. ".bin" is the output format from AIDA. And you don't have attached all the SSDT files. This SSDT is for your CPU.

what do you mean with "And you don't have attached all the SSDT files. This SSDT is for your CPU."?? i only have this SSDT file

Retry to extract SSDT with AIDA because you don't have the method in these files for desactivate the graphic card.

Hi,WHit3Spirit,I have a question.In your methods M_ON and M_OF, why do you add something like "If (CondRefOf(...)) {...}"? Why not just write

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

Thank you

That's a good question.

I repeated the formula of RehabMan but I do not know why he chose this. Ask him. ^_^

Precaution. For the case of "pilot error" and SSDT doesn't get loaded in ACPI namespace...

hello,

 

i have an hp envy 17t-j100, haswell i7-4702mq, Intel HD Graphics 4600, nVidia GT 740m

 

i want to turn off my nvidia card, i extracted my dsdt and all ssdt files using linux and latest iasl. just to be sure, i also extracted them using AIDA (windows) and maciasl (with updated iasl 5.0). i had the same result using these methods.

 

i have this ssdt-5.aml file with 11 errors, i don't know how to fix. this is the file i believe that needs to be patched.

 

could you please help me fixing them?

 

find below the iasl log

Extract all DSDT/SSDT from Linux. Place in a single directory. Use 'iasl -da *' to disassemble them as a group.

dear rehabman,

 

sorry for my noobness, your advice worked like a charm.

 

i had only one error, which i could fix easily by deleting a line.

 

i'll try to turn my nvidia 740m card now by following the op steps.

 

thank you very very much, if i suceed i'll post my ssdt file here!

hello again,

 

unfortunately i am unable to make this method work for me.

 

i use clover bootloader v2721, and the following files in \efi\clover\acpi\patched

 

dsdt.aml (various patches)

ssdt.aml (ssdtPRGen.sh generated)

ssdt-1.aml (brightness fix)

ssdt-2.aml (bcm94352 wifi dualband enabler)

 

for this reason, i cannot set dropoem=false in clover, otherwise i'll loose brightness fix, wifi dualband enabler and speedstep.

 

i'll attach my patched and pure (original) dsdt/ssdt files.

 

i would be grateful if you could let me know how to proceed to turn nvidia card off, without loosing speedstep, brightness fix and wifi dualband.

In order to provide patched SSDTs you must use DropOem=true.

In your patched_dsdt_ssdt folder, ssdt-1.aml and ssdt-3.aml are duplicates (well, one is patched and other not).

What is the intention?

 

ssdt-5.dsl should be patched for turning nvidia off. It needs GFX0->IGPU rename and call _OFF from _INI.

 

With Clover, you can keep the original names of the SSDT files (no need to rename sequentially). It may be best to name your additional SSDT files with suffixes 10 or larger (eg. SSDT-10.aml) just to avoid confusion with those SSDTs that are patched.

i forgot that i had already used it in ssdt-1.aml. and due to my lack of knowledge, i tried to patch original ssdt4, named ssdt-3.aml, which didn't work.

dear rehabman,

 

i made two attempts to patch ssdt5.dsl

 

in the first one, i tried to follow your instructions

 

in the second one, i tried to implement the op's instructions

 

unfortunately none of them worked, probably due to my lack of knowledge

 

could you please point what i am doing wrong, so i can have directions on what to search and learn?

 

__________________

 

regarding the ssdt*.aml renaming, i renamed

 

ssdt.aml => ssdt_pr.aml

ssdt-1.aml => ssdt14.aml (ssdt4 patched)

ssdt-2.aml => ssdtwf.aml (ssdt wifi dual band enabler)

 

but then clover loaded none of them

 

so i renamed them to their previous names and clover loaded them as usual

 

 

 

if anyone else can help too, any and every help is very welcome!!!

 

thank you!

SSDTs must be named SSDT.aml, SSDT-n.aml, or SSDT-nn.aml where n is a digit 0-9, and nn two digits 10-19.

From Clover source:

CHAR16* ACPInames[NUM_TABLES] = {
    L"SSDT.aml",
    L"SSDT-0.aml",
    L"SSDT-1.aml",
    L"SSDT-2.aml",
    L"SSDT-3.aml",
    L"SSDT-4.aml",
    L"SSDT-5.aml",
    L"SSDT-6.aml",
    L"SSDT-7.aml",
    L"SSDT-8.aml",
    L"SSDT-9.aml",
    L"SSDT-10.aml",
    L"SSDT-11.aml",
    L"SSDT-12.aml",
    L"SSDT-13.aml",
    L"SSDT-14.aml",
    L"SSDT-15.aml",
    L"SSDT-16.aml",
    L"SSDT-17.aml",
    L"SSDT-18.aml",
    L"SSDT-19.aml",
    L"APIC.aml",
    L"BOOT.aml",
    L"DMAR.aml",
    L"ECDT.aml",
    L"HPET.aml",
    L"MCFG.aml",
    L"SLIC.aml",
    L"SLIT.aml",
    L"SRAT.aml",
    L"UEFI.aml"
};
So, ssdt_pr.aml, ssdt14.aml, and ssdtwf.aml are all invalid.

 

I think this misunderstanding might have affected your results.

i renamed them according to your instructions, but it seems it made no difference comparing to the lowercase letters. but i'll keep the uppercase naming.

 

SSDTs are being loaded (brightness fix implemented from SSDT-14.aml [sSDT-4 patched] is working), but NVIDIA card stays on.

 

could you please tell me if this way of calling _OFF from _INI in SSDT-15.aml (SSDT-5 patched) is correct?

Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            _OFF ()
            Store (Zero, \_SB.PCI0.PEG0.PEGP._ADR)
            Store (NVSD, \_SB.PCI0.PEG0.PEGP.NVID)
        }

thank you.

FAT32 is case insensitive.

I would call it at the end of _INI. If still not working, post ioreg (use IORegistryExplorer v2.1).

good guide!!!

 

but i haven't followed, what does it mean: "After that, call M_ON method in _PTS (Prepare To Sleep) so that the _WAK after sleep can shutdown the card. (thanks to RehabMan)"

 

it means: the graphic card will be active when the laptop goes to sleep and during the sleep? and then when it wakes, then _wak method is called, and thus the graphic card is shutdown again? is that what you actually mean?

but if the graphic card is not active when the _WAK() method wants to call M_OF() during the waking, then it will probably cause error, right?

Yes, this is a fix for restart/sleep problems. Do this part only if necessary. Based on what we found with the HP ProBook. Your machine/DSDT may vary.

 

And I would suggest calling _ON from the beginning of _PTS, and _OFF from the end of _WAK. Of course, this assumes your _WAK/_PTS are executing from beginning to end, which everyone should verify by using ACPIDebug.kext.

      I have tried to install clover via no UEFI legacy mode (and with UEFI method) using the method here (http://www.tonymacx86.com/yosemite-desktop-guides/144426-how-install-os-x-yosemite-using-clover.html)
      both times I can get to just past the clover boot screen and it freezes after that.
      I have verbose (-v) selected in boot options: On the non-UEFI install then it hangs on:
      "Waiting on <dict ID="0"><key>IOProviderClass</key>...."
       
      I have had a lot of issues with trying to get the installer working and many different things that had to be disabled but now it just gets to here and stops. Some times it will glitch out on this screen and give me a the circle with the line through it and text garbage around it where the text in the pictures are.
       
      Need help please.
       
      This is the laptop im using the specs are the same nothing has changed.

      I came to the conclusion that it is a random kernel panic because sometimes it starting up and other times it isn't starting up

      As you might know the Samsung 970 EVO Plus variant causes major issues on hackintosh installs. I want to keep it plugged into my motherboard for use in Windows. However, if it's plugged in, macOS is going to try to index this disk eventually and it will crash macOS even though it's not the main install disk. 

      Because I don't need this disk under macOS I thought it would be a good solution to somehow disable/hide the unsupported disk for macOS. I looked into doing this via Clover but couldn't find anything useful. I'm hoping I can disable the slot via a DSDT patch. I only want to disable one specific M.2 slot, the others should remain functional (I have another working M.2 disk). So disabling the driver is not an option.

      I have very little experience with DSDTs and I have no idea how to do this. I recently created a USB injection patch using RehabMan's excellent guide, so I have some experience with the process, but no idea how to formulate the DSDT patch. 

      I have a Gigabyte Aurus Pro z390 motherboard. Below is a screenshot of IORegistryExplorer showing the other working drive (not the one I want to disable, that one is not plugged in yet). 
       

      I would be very grateful if anyone can point me in the right direction. If anyone knowns of a non-DSDT solution to disable a specific slot (but not all slots) then that's also fine of course.

      Thank you for your time

      Hi, I followed the rehabman guide (linked in the vanilla guide on the side of r/Hackintosh, not sure if I can link it) for laptops for my yoga 730ILW13 with an 8265u, Conexant 11870, 8gb of ram, 13.3" fhd and I found that upon booting the installer usb I get this weird issue where the screen displays what it should but the screen is incredibly dim (though it was off before using a flashlight on it) and it flashes every few seconds for a few milliseconds to the correct brightness, I used the plist for hd615-650 (including my 620), not quite sure what could be the culprit, first time hackintoshing a laptop so it might be a stupid brightness kext I forgot but didn't find any in that post or in this forum :c 
      Attached the clover zip so that anyone with more experience than me might give an idea in what could be a way to fix this.
      Thank you in advance

      - App Store, Messages, FaceTime, Siri, iCloud(native)
      - Integrated webcam(native)
      - 3.0 USB (native)
      - Touchpad and Keyboard(ELAN501): Fn keys are good, the weird thing is the Brightness key. On my keyboard it's Pause Break:Br-up, Fn+F12:Br-dwn-> To fix this try Karabiner (VoodoPS2Controller.kext), - for gestures try SmartTouchpad drivers
      - Battery info:Install ACPIBatteryManager.kext with Kext Utility or other installer.
      - Sleep Mode
      - SSD with TRIM enabled (to enable trim, open Terminal and write "sudo trimforce enable")
      Not working:
      - Original Wi-Fi (Qualcomm Atheros QCNFA344A):  unsupported, you need switch to BCM94352Z or just use a mini usb wifi dongle.
      - NVIDIA GeForce GTX 950M: Optimus not supported.
      - Card Reader: Unsupported -> Can't really fix because I don't have any SD Card at the moment, maybe can be fixed by adding Prod & Ven IDs to AppleStorageDevices.kext, I never used it anyway. name: "USB2.0-CRW" Prod ID: "0x0129" Ven ID: "0x0bda  (Realtek Semiconductor Corp.)"
      For Wi-Fi:
      - 1st method:You can choose an external USB wifi dongle (I used TP-Link Archer T1U (5GHz support), TP-Link has official macOS drivers, you just need to install it
      -2nd and I think the best method:Replace your M.2 Qualcomm Card with a compatible BCM94352Zcard (you will have hand-off Bluetooth too), just install the kexts (enabled with BrcmFirmwareData.kext, BrcmPatchRAM2.kext, FakePCIID.kext, FakePCIID_Broadcom_WiFi.kext, they're all in my attached zip). You could buy this card from ebay, aliexpress, or amazon
       
      Issues:
      - None
      BIOS Settings:
      - BIOS version 1.15 (irrelevant)
      - Secure Boot: Disabled
      - Touchpad: Advanced
      - Boot mode:UEFI
      Getting ready for Installation:
      - Download the install zip (bootpack & postinstall): Click here -> acer_aspire_v591g_installfiles.zip
      Installation:
      - Create an installer with any method you know (- Mac: createinstallmedia - Windows: Transmac, Vmware, Win32diskimager)
      - Copy my Clover folder to the USB's EFI folder
      - Boot with the Installer USB
      - If you stuck in boot, reboot and in the Clover bootloader select "config_debug.cfg" -> you'll have more informations about the freeze
       
      Please open the README.rtf in my install zip for more informations about the USB Installer & Post installation!
      If you have a single RAM and getting panic at boot, then you need to edit the "config.plist" with these (SMBIOS->after "Version 1.0"):
      ->Edit "Frequency" and "Size" to match your RAM values
      <key>Version</key> <string>1.0</string> <key>Memory</key> <dict> <key>Channels</key> <integer>1</integer> <key>SlotCount</key> <integer>1</integer> <key>Modules</key> <array> <dict> <key>Slot</key> <integer>0</integer> <key>Size</key> <integer>8192</integer> <key>Frequency</key> <integer>2133</integer> <key>Type</key> <string>DDR4</string> </dict> </array> </dict> </dict>  
      PowerManagement  fix:
      Set HWPEnable=YES in Clover (already set), CPUFloor to "700", Frequency to "2300" and "3200"(Normal and Turbo, if you have i7-6700HQ version then it should be "2600", "3500") and "FrequencyVectors" from "0x0d000000" to "0x07000000" in "S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Mac-A5C67F76ED83108C.plist", MSR _xcpm_idle Patch to KernelToPatch in Clover (If you have High Sierra, change "MatchOS" to 10.13):

      <key>KernelToPatch</key> <array> <dict> <key>Comment</key> <string>MSR 0xE2 _xcpm_idle instant reboot(c) Pike R. Alpha</string> <key>Disabled</key> <false/> <key>Find</key> <data> ILniAAAADzA= </data> <key>MatchOS</key> <string>10.14</string> <key>Replace</key> <data> ILniAAAAkJA= </data> </dict> </array> Reboot, and it's 800MHz in idle state, same on Windows.
       

       
      Before updating to a new version of Mojave please update kexts (and clover if necessary) to newer versions to avoid kernel panics.
      Generate a serial number with Clover Configurator.app (open up your config.plist with CC then -> SMBIOS -> Serial Number -> Generate New)
      Mojave & Windows 10 Dual-Boot:
      Dual-boot clean install (on one drive), UEFI Only:
       
       Boot into your Mac installer, Create 2 partitions in GUID table (1 for Win (I used FAT32 but I think it doesn't matter what you choose), 1 for Mac),   Install Mac, boot with your USB, mount your EFI partition (use terminal or an EFI mounter app), create an EFI folder (if there is no folder), copy the CLOVER folder I attached to the EFI folder, restart,  Boot into your Win installer, Format the partition you created for Win, install.   Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       5.  You're done! It will booting into Clover when you start the system, and you can select Win or Mac (or another OS if installed on a 3rd partition).
       
      Dual-boot with Windows installed first (on one drive), UEFI Only:
      If you already have Windows and you don't want to lose all your data there is a hope:
      I created a video from this restore method: [Hackintosh] Dual-Boot High Sierra & Windows - when Windows already installed - no data waste - UEFI
      You need bootable Mac Installer and a full system restore image (link is in my video's description).
      (You may see errors if your EFI partition is not 200 MB)
       Boot into your Windows, resize your partition or create one for Mac.  Boot into your Mac installer and in Disk Utility format the partition you created.  Restore from image: select your full system restore image.  When it's finished restoring you just need to restart, then boot to the system with your usb.  When you successfully booted to Mac desktop, mount your EFI partition (use terminal or an EFI mounter app), open EFI, you will see there is a Microsoft folder already (don't touch that!). Copy my CLOVER folder to the EFI folder then Restart.  Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       7.  You're done! You can select your old Windows and your new macOS!
      (Only tried with Windows 8/8.1/10. I don't know Windows 7,etc.)
       
      IF YOU GETTING ERRORS DURING MAC RESTORE:
      - Make sure you have partitions in GPT
      - Windows using 100 MB EFI and will annoy the Mac restore. Don't worry, just ignore the errors.
       
      IF YOU GETTING ERRORS DURING WINDOWS INSTALLATION (could not be formatted, etc):
      - Make sure you have GPT partitions, and GPT (UEFI) installer, also disconnect all external storage drives (except the installer USB)
       
      IF YOU USED RESTORE METHOD THEN CAN'T MOUNT YOUR EFI PARTITION (No EFI partition found):
      - It's because your EFI is not 200 MB or not an "Apple" original EFI,  but do not worry, try another EFI mounter, or mount from terminal (I used EFI mounter v3: Getting errors, but you can mount and use without problem)
      - You also could "mount" the EFI from Windows:
      1st method: open cmd in administrator mode and type:
      diskpart
      list vol (Now select the "System" volume,(FAT 32) For example I select 4)
      sel vol 4
      list part(Select System type partition, for example 2)
      sel part 2
      assign letter=b(This will "mount" your EFI partition)
      Open Explorer++ or TotalCommander in administrator mode to manage EFI
      remove letter=b (This will "unmount" your EFI)
      2nd method: open cmd in administrator mode and type:
      mountvol b: /s (This will mount your EFI)
      Open Explorer++ or TotalCommander in administrator mode to manage EFI
      mountvol b: /d (This will unmount your EFI)
      Thanks to all OSXLatitude members for helping me out! (Jake Lo, Hervé, Bronxteck, black.dragon74)!
