Hi, I would like to know if you can help, I have a problem with my old system, I have tried to install High Sierra, but I have not managed to make the acceleration of graphics work on my video card NVidia Geforce 9400 GT, eh intendo a lot of methods without Any success, the system recognizes my card and all its data correctly but the acceleration of graphics does not work, this problem is due to install a processor Xeon e5450 3.0ghz Mod 771 to 775 LGA, since installing this peocesador the graphics stopped working and what appeared was a glitch on the screen that shows absolutely nothing, to enter the system I had to enter with bootflags nv_disable = 1 in clover configurator, I have managed to see in other post information to this problem and say that it has been solved with the bootflag npci = 0x2000 and npci = 0x3000 to solve the Glitch on the video card, in my case the boot system is restarted, after a lot of frustration for wanting to start with the graphics, delete all the kexts of graphics cards ATI, Nvidia, from the folder System \ library \ Extensions \ and success !! .... the glitch of the graphic card disappeared completely, the problem of the glitch on the screen was generated by the kexts nvidia, now I can start with Inject Nvidia, but e peoblema is that now the graphics do not work with acceleration, I do not know what to do with this peoblema, my motherboard is Intel DG41TY. another person suggested modifying my dsdt.alm but I could not compile the code provided to me, I get an error in DSDTSE. please maybe you can help me with this problem. I will leave you the link where is the information to compile the code of my nvidia geforce 9400 to my dsdt.alm...... I am the user X_SIRIUS https://www.tonymacx86.com/threads/nvidia-geforce-9400gt-on-sierra-not-works-ok-kernel-panic-nvdastartup-kext.206208/page-2#post-1793409 



I'm trying to install the code in the dsdt.alm I copy the respective code to my Geforce 9400 GT 1024MB nvidia card.

But when I want to compile the file, the DSDTSE program tells me that I have 1 error, 3 warnings, 1 remarks, 49 optimizations.

I try to find the file dsdt.alm that the program saved and I can not find it.

My Motherboard is Intel DG41TY.

here I will upload my dsdt of my current mother card, maybe you can help me compile the code without errors, please


This is my DSDT from my Motherboard Intel DG41TY acpi_dsdt.aml

      if a web driver is NOT installed, what happens??
      I used AMD RX560 in Sierra, but it is very unstable. usually gpu crash or window server crash occurred.
      so now I attached nvidea Quadro FX1700 to my Sierra. I know FX1700 works well in High Sierra, but I haven't tried it in Mojave yet.
      FX1700 works well without any additional kext, even nvidia web driver.
      I plan to buy a nividia card. I would like to know if a nvidia card, especially kepler, maxwell, pascal, works without web driver.
      just curious.

      Hey guys,
      I'm really hoping someone has the experience and ability to help me iron out the last remaining issue on my build.  
      The motherboard is: Gigabyte Z370 Aorus Gaming 7 and I'm running a Alpine Ridge thunderbolt card (Revision 2).   I've gotten everything working for the most part with the exception of Thunderbolt hotplug.  This is the last piece of the puzzle.  I've tried so many different DSDT/SSDT's, cable plugged in, and unplugged, without any luck at all. 
      I've managed to get my Focusrite Clarett 8Pre Thunderbolt working and it's showing up under the PCI section.  It works great, until I shut the device off and turn it back on.  I'd really like to try to get this hotplug issue sorted out, but I've had absolutely no luck so far.
      I've managed to get the Alpine Ridge NHI and USB controllers showing up in the PCI section too, but for some reason, the USB lists a bunch of ',,,,,,,,' after the name. 
      I'll be the first to admit - I don't really know a whole lot about what I'm doing with this stuff, but I've attached relevant files in hopes someone more experienced and knowledable can help me get this working.  
      Thanks guys!

      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 issues 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.
      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
      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.
      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.

      You can try to use NDRVShim.kext instead of replacing IONDRVSupport and IOGraphicsFamily post#1875, get NDRVShim.kext from post#1865, at /Volumes/macOS Mojave Patcher/macOS Mojave Patcher.app/Contents/Resources/macOS Post Install.app/Contents/Resources/legacynvidia/NDRVShim.kext
      And need to edit NVDAResmanTesla.kext/Contents/Info.plist to add the following string.

      And My nVidia 9300GE always need to fix reboot error with NVDAStartup.kext.310.42.25f01.zip from nawcom since 10.12.
      Download all the patche kexts here. All works fine here too.
      It's better to use Kext Utility.app to install kexts.
