      This project is dedicated to the memory of Mausi, the cat I loved more than anybody else.
       

       
      A few days before Christmas I started my latest project, a new driver for recent Intel onboard LAN controllers. My intention was not to replace hnak's AppleIntelE1000e.kext completely but to deliver best performance and stability on recent hardware. That's why I dropped support for a number of older NICs. Currently the driver supports:
       
      5 Series
      82578LM 82578LC 82578DM 82578DC 6 and 7 Series
      82579LM 82579V 8 and 9 Series
      I217LM I217V I218LM I218V I218LM2 I218V2 I218LM3 100 Series (since V2.1.0d0)
      I219LM I219V 200 Series (since V2.3.0d0)
      I219LM I219V 300 Series (since V2.4.0d0)
      I219LM I219V  
      Key Features of the Driver
      Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission. No-copy receive and transmit. Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. TCP, UDP and IPv4 checksum offload (receive and transmit). Support for TCP/IPv6 and UDP/IPv6 checksum offload. Makes use of the chip's TCP Segmentation Offload (TSO) feature with IPv4 and IPv6 in order to reduce CPU load while sending large amounts of data (disabled due to hardware bugs). Fully optimized for Sierra (64bit architecture) but should work with older 64bit versions of macOS too, provided you build from source with the appropriate SDK for the target OS. Support for Energy Efficient Ethernet (EEE). VLAN support is implemented but untested as I have no need for it. The driver is published under GPLv2.  
      Current Status
      The driver has been tested successfully with I217V, I218V and 82579V under 10.9.5 and above. The attached archive includes source code as well as a prebuilt binary (debug version) for Mavericks and newer versions of macOS.   Known Issues
      There seem to be problems while using VMware with version 1.x.x of the driver. In case you are affected use version 2.0.0 or newer.  
      FAQ
      Could you add support of for...? Well, you are probably asking me to add support for one of the older NICs like the 82571/2/3/4L or 82583 and the answer will be no as I dropped support for these chips intentionally. They are broken and I lost more than 2 weeks trying to make it work on the 82574L without success. I was asked to add support for I210, I211 and I350 but as these chips have a completely different architecture, which isn't supported by the underlying Linux driver, this is impossible, sorry. Does it work with Snow Leopard or 32 bit kernels? No and I have no plans to make a version for 32 bit kernels or anything older than Lion. WoL from S5 doesn't work with this driver but under Windows it's working. Is this a driver bug? No it isn't, the driver is working as it should because OS X doesn't support WoL from S5.  
      Installation
      Goto /S/L/E and delete AppleIntelE1000e.kext. Recreate the kernel cache. Open System Preferences and delete the corresponding network interface, e. g. en0. Reboot. Install the new driver and recreate the kernel cache. I recommend to use Kext Wizard or a similar utility for the installation. Reboot Open System Preferences again, select Network and check if the new network interface has been created automatically or create it manually now. Configure the interface.  
      Help - I'm getting kernel panics!
      Well, before you start complaining about bugs after you upgraded macOS and ask me to publish a driver update, you should first try to resolve the issue on your own by cleaning the system caches.
      As the driver uses macOS's private network driver interface, which is supposed to be used by Apple provided drivers only, you might run into problems after an OS update because the linker may fail to recognize that IONetworking.kext has been updated and that the driver needs to be linked against the new version (Apple provided drivers avoid this problem because they are always updated together with IONetworking.kext). As a result, the linking process produces garbage and the driver may call arbitrary code when trying to call functions from IONetworking.kext. This usually results in unpredicted behavior or a kernel panic. In order to recover from such a situation, you should clean the System Caches forcing the linker to recreate it's caches:
      Delete all the files in /System/Library/Caches and it's subdirectories but leave the directories and the symbolic links intact. This is very important! Reboot. Recreate the kernel cache. Reboot again.  
      Troubleshooting
      Make sure you have followed the installation instructions especially when you have issues with certain domains while the others are working fine. Use the debug version to collect log data when trying to track down problems. The kernel log messages can be retrieved with "grep kernel /var/log/system.log" in Terminal. Starting from Sierra use "log show --predicate "processID == 0" --debug" in order to retrieve kernel logs. Include the log data when asking for support or giving feedback. I'm an engineer, not a clairvoyant. Don't copy and paste large amounts of log data to your post. Create an archive with the log data and attach it to your post. In case you don't want to make your log data publicly accessible, contact me via PM and I will provide you a mail address to send it directly to me.  Check your BIOS settings. You might want to disable Network Boot and the UEFI Network Stack as these can interfere with the driver. Double check that you have removed any AppleIntelE1000e.kext from your system because it could prevent the driver from working properly. Delete the following files: /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist /Library/Preferences/SystemConfiguration/preferences.plist Verify your bootloader configuration, in particular the kernel flags. Avoid using npci=0x2000 or npci=0x3000.  In Terminal run netstat -s in order to display network statistics. Carefully examine the data for any unusual activity like a high number of packets with bad IP header checksums, etc. In case auto-configuration of the link layer connection doesn't work it might be necessary to select the medium manually in System Preferences under Network for the interface. Use Wireshark to create a packet dump in order to collect diagnostic information. Keep in mind that there are many manufacturers of network equipment. Although Ethernet is an IEEE standard, different implementations may show different behavior causing incompatibilities. In case you are having trouble try a different switch or a different cable.

      Hi, i've installed on my pc MacOS Mojave but after installation my pc, sometimes, crash giving kernel panic.
      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
       
      My PC:
      CPU: Intel i7 6500U
      LAN: RTL8100
      Wi-Fi & Bluetooth: Dell DW1820A

      Boa noite galera!
       
      já a alguns anos que tenho hackintosh, é um I7 6700K em uma Asus Maximus Hero VIII Z170 com GPU RX480 8gb
      Porém desde sempre tenho congelamentos aleatórios, na maioria das vezes quando coloco um filme pra exportar no final cut. mas já aconteceu enquanto via videos ou escutava musicas no spotify e recentemente até ao ligar o computador, mal ligou congelou. ele congela todo não dá pra mexer em nada, só desligando segurando botão power que ele volta.
       
      Me disseram que era gerenciamento de energia, eu baixei a DSDT do meu processador, segui alguns outros tutoriais e ainda nada. não consigo de jeito nenhum resolver esse problema, já instalei varias versões desde o yosemite até o High sierra, e ainda nada. Só esse pequeno detalhe que me desanima do Hack. 
       
      Alguem pode ajudar?

      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

      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 show 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 dGPU to iGPU and vice-versa.
       
      Cheers!
