Hi, please excuse my lack of knowledge since this is all new to me. When I go and look at the system report (brand new MacBook Pro 13") the kext listed under the ethernet cards section is /System/Library/Extensions/AppleUSBECM.kext.  Does this mean I cannot use this driver? I am having the problem where it says my cable is not plugged in after sleep. Thanks for your help!

Issue:

My issue is that my wired network will work fine and then immediately stall. For example, if I go to fast.com after rebooting my Mac, it will jump up to an OK 25Mbps. If I try to run the test again, it will go as high a few Kbps and then fail to complete altogether. Any test is the same—a download starts fast and then stalls, a Youtube video starts playing, then stalls. This stalling will continue until I restart the system altogether. Once I restart the system, it starts over the exact same. I've tried installing the IntelMausiEthernet.kext to the EFI partition as well as to the L/E path with the same result. This happens for both internet and local network activity. I've tried reinstalling, verifying that the IntelMausiEthernet kext is installed, verified that the correct hardware is present in the system report, and verified that the internet works without issue from the BIOS (downloaded firmware update without issue). I've went through the BIOS settings and disabled/enabled items based on the feedback through this mega-thread. I'm not really sure what to try next. Thanks in advance.

My Issue is that when attempting to use Blizzards Battle.Net Application to download World of Warcraft, the installation package fails constantly saying "Can not communicate with server", while everything else continues to work fine. i honestly dont even know what additional information i could supply to assist with this other than that, sorry. :'(

If the problem is limited to a certain service, a driver error can be ruled out. At first glance looks more like a firewall or routing related issue. Is MSS clamping configured properly? What about the firewall rules? Are all required ports accessible?

no firewall turned on. works fine on windows but not OSX so not a router issue. where do i set MSS on OSX? Google just has windows links. no specific ports turned off, again, works fine on windows, not on mac. Gatekeeper disabled, Wow and Battle.net added to accessability, what im guessing is going on is the same thing that was described on a previous page (Here), where downloading large files craps out the connection... but the fix file you listed was Mojave only. im running High sierra.

Hey again,

 

pretty much certian that what i was mentioning in my previous message is whats happening. files will download for a few min, then stall, then start again. would compiling 2.5.0d0 for high sierra potentially fix this?

I compiled the 2.5.0d0 listed on Github, compiled under High Sierra, and installed. and now i have no internet connection at all. (copied kext into /l/e, sudo kextcace -i /, delete connections under prefpane, reboot) and even more strangely, after reinstalling the one i had that WAS working, i still can not get ethernet back up and running without reinstalling OSX completely from Ground up. im pretty confused.

Hi

I don't understand why you've compiled v2.5.0d0 from source. A zip file is posted on this thread. 

 

Few questions:

  • Do you install Clover UEFI/ESP?
  • If yes, install 2.5.0d0 in EFI/CLOVER/Kexts/Other instead of L/E

Uninstall 2.5.0d0 in L/E and repair permissions (you can also rebuild cache...) with KCPM Utility Pro: Here

@Matgen84 You've probably got a messed up system which prevents the driver to be linked properly against IONetworking. kext. In order to resolve the issue, clean the system caches (this is not the same as the kernel cache, use the search function to find out how to do this) and, after that, recreate the kernel cache.

FWIW, I was able to compile 2.5.0d0 with Xcode 9.x for usage on High Sierra. Make sure the target is 10.13, not 10.14. I believe the ZIP posted earlier in the thread is for Mojave only.

Correct! The binary I posted is for Mojave but you may build it for High Sierra too, provided you've changed the deployment target to 10.13.

Hello, @Mieze.

 

First, thank you very much for IntelMausiEthernet and for the patch for AQC107.  Both have helped me a lot.

 

Secondly, I have been using IntelMausiEthernet 2.5.0d for a few weeks and just realized that "Wake for network access" doesn't work with 2.5.0d.  Reverting back to 2.4.0 and it works perfectly.

 

Again, thanks.

 

Cheers.

I only comment what @Kazlehoff said. I've got no problems with your great kext. For now I use 2.4.0 on Mojave.

EDIT: *Nevermind* My network is performing flawlessly with 2.5.0d.  Turns out the SATA drive I was using was causing the issue.  I installed a NVME WD Black and my transfers are a steady 98-99MB/s with no system slow down.

 

Sorry for the false report, deleting the below info to avoid confusion for others.

for mojave. im on high sierra.

 

i got my ethernet issue solved on the new driver (seems to be happer on the EFI partition in efi/clover/other instead of /library/extensions

 

however, my issue is persisting. it may honestly be related to poster above me's issue... could we be looking at a particular issue with the z390 boards?

I ran some tests with version 2.5.0d0 of the driver and I haven't noticed any problems with WoL. It works as expected. You might want to clean the system and kernel caches. In case a driver isn't linked properly, strange things may happen. I've also seen this many times.

Just to follow up, you were 100% correct...

sudo touch /System/Library/Extensions

sudo kextcache -i /

 

Fixed my WoL issue.  Thank you for your time and sorry for reporting a false bug.

 

Cheers!

      Just recently installed Mojave on my yoga 730(i5-8250u, 8gb of ram and 1080p 13.3" touchscreen) and got many features working, now the only issues are that my igpu is shown as only 7mb(and not metal capable, not sure whether it is or not) even tho I should've changed it from 5917 to 5916 (added both EFI folder and send me), the screen is shown as a 30.5" in system information and the cpu even tho I extracted the ssdt for it with ssdtPRGen.sh and appleintelinfo.kext to get low frequency info (ssdt was done with info 15,400,1600,3400 so it should go between 16-3400mhz and down to 400 in idle), idk what is wrong with my installation, can you guys help me or linke me something to fix those issues?

      Introduction
      The H370 chipset powers 8th generation Intel Core-i CPUs. Even though the name H370 rings comparable to Z370, the H370 is based on newer silicon. This it also requires some new approaches compared to the Z370. An example would be on-die USB 3.1 and WiFi support.
       
      Since this guide is not a "hold-your-hand-every-step" guide, I assume you know:
      Clover installation and configuration How to create an install medium for MacOS Access and configure the BIOS Have heard of ACPI patching (I'm a newb at this myself)  
      What works
      Sleep (via DSDT edits and emulated NVRAM) On-board Audio (via AppleALC and native AppleHDA) Native power management (without any kext or patch) All USB ports (and only those present are active) iGPU for both acceleration and display dGPU (I'm running an Nvidia GTX 1080)  
      Untested
      NIC --> I'm using WiFi only  
      What doesn't work
      Native NVRAM via AptioMemoryFix.efi DMVT Pre-alloc higher than 64MB (but not necessary)  
      Community additions
      User @Panzerschiffe added a helpful post, altering this guide for user with AMD cards and not needing on-board sound.
      He also runs Mojave, which I don't run yet.
       
       
      Changes to the guide:
      22.5.18: Added SSDT hot-patching to enable sleep, replacing DSDT static patching as an alternative.
      23.5.18: Add iMac18,1 as alternative SMBIOS config for those relying on the iGPU for output
      25.6.18: Added update info
      28.8.18: Small changes for clarity, changed info for afps loading & updated USB patch for 13.6
      04.10.18: Update to Mojave will come once Mojave is more mature
      02.12.18: Removed unnecessary patches, fakepciid and audio patch method & linked to AMD post & added whatevergreen.kext as replacement for previous GPU kexts
      02.03.19: Removed unnecessary fakeid and ig_platform_id injections, ACPI patches - this is all handled by whatevergreen & lilu. In testing is a Framebuffer patch, see this post.
      04.03.19: Added Germany keyboard layout and updated pre-patched DSDT.aml removed DSDT patching
       
       
      1. Installation
      This guide heavy inspired by the work of /u/corpnewt of /r/hackintosh and his (sorta) Vanilla guide
       
      1.1 Create the install media for MacOS
      Follow this, if you are using a Mac to start off with. If you are totally new to MacOS, then please check the basic guide Creation of an installer media in windows or linux
       
      1.2 Install Clover on the install media
      Using the Clover installer, ensure you are installing to the USB medium you are using for the installer.
      Chose the following options, leaving the others on default: 
       
      UEFI driver: AptioMemoryFix UEFI driver: ApfsDriverLoader UEFI booting only Install to ESP  
      You have to get your hands on an apfs.efi. A google search can help, or extracting it from the Installer package. Make sure you procure a version matching the MacOS version you are about to install. Place the apfs.efi in drivers64UEFI.
       
      1.2 Adjust the config.plist for the installer
      You can use the config.plist attached as a guideline, but take a look at it before and at least adjust the SMBIOS - otherwise it won't boot.
      Attention: The attached plist contains audio patches introduced by a post-install step. If you run into problems, you might remove those. It also contains a manual slide value, which should normally not be needed, but works fine for me. It is also tuned for usage with an Nvidia Pascal dGPU as main GPU.
       
      The config you create now should serve you nicely for install and running the system.
       
      Take care of adding the following basics:
      SMBIOS: iMac18,3 - You can generate a serial number via Clover Configurator. The creation of a proper SMBIOS is covered in many guides to good extend Note: If you aim at using the iGPU for output, a user reported that iMac18,1 works better - since iMac18,3 produces severe flicker. I'm now also testing 18,1 Look at the graphics section and adjust the injection for Intel to your situation  
      Fixes

      Patches

      Devices

      Graphics
      Important:
      Change 0x59120003 to 0x59120000 if you don't use a dGPU as your main display Driver and instead use the iGPU for output.
      Also note. SMBIOS iMac18,1 has been reported to work better in this configuration. But 18,3 works fine for me.

      Kernel and Kext patches
       
      1.3 kexts and friends
      Add the supplied SSDT-UAIC.aml to "patched" - it limits the injected USB Ports to the actual number and ports valid for this board.
       
      Required kexts on "Other":
      FakeSMC.kext Whatevergreen.kext Lilu.kext AppleALC.kext IntelMausiEthernet.kext in case you're running Ethernet USBInjectAll.kext with the HCI-300-series-injector.kext --> These two should be installed to /L/E after install  
      We are leaving sound out at the moment, this is something for post-install.
       
      1.4 Check BIOS and install
      You should be ready for install. But before you reboot, please take a look at your BIOS and set it up accordingly (copied from the aforementioned guide and adapted):
      Load Optimized Defaults Disable VT-d setting If your system has Secure Boot Mode, disable it Enable CSM - This is sometimes needed to dual screens to work Set OS Type to Windows 8/10 or OtherOS - I have not seen a difference Turn off internal Serial and Parallel port Turn off Network stack for boot Turn off wake-on-lan (for now) Set XHCI Handoff to enabled Don't enable decode over 4G Depending on your GPU, set priority for boot Set internal GPU (iGPU) to enable - not auto or disabled Set DMVT pre-alloc min to 64MB and max to 128MB. For this selection to appear you might need to reboot after setting iGPU to enable Set USB legacy to enabled Activate XMP profile 1 f your Ram has it (mine doesn't and I added the timings manually) Set ERP to enable, disable platform power management (I need to do more research if this could be enabled)  
      I've attached my current BIOS config "hack2". You can place that on a fat32 drive (the EFI partition of your install USB drive might be an idea) and see if it loads. It's made for and with the F2 BIOS.
       
      The install itself should be like other MacOS Hackintosh installs with it several reboots and ensuring to select the correct boot device in Clover.
       
      2. Post-install
       
      2.1 Install clover on target
      This is a no-brainer, but install a fresh copy of Clover on your target medium.
       
      During install select again AptioMemoryFix but also additionally
      EmuVariableUefi-64.efi Install RC scripts on target volume because otherwise NVRAM doesn't seem to work
       
      After the install, copy
      config.plist contents of "Other" content of "patched" to your new clover install.
       
      2.2 Edit ACPI for slumber
      Choose one option, not both. The hot-patch is experimental, but for the moment it is stable.
       
      2.2.1 Edit DSDT
      No more need for manual DSDT patching. If you still do it, you might run into unstable sleep. SSDT hot-patching + sane clover.config edits are enough
       
      This is necessary only once on initial install and every time, you edit or upgrade the BIOS. The DSDT.aml attached to this post might work for your system or give you a file to compare to. Don't expect it to work for you, though.
      EDIT: Since moving from F2 BIOS to F12 I did not repatch and sleep is still somewhat reliable. But to be 100% sure, you can still follow these steps.
      I won't go into the details of DSDT extraction and patching. There are better guides (the linked guide is a rip-off of rehabman's guide from a different forum). Please follow such a guide to extract your ACPI data.
       
      Locate and disassemble the DSDT with the newest iasl binary you can put your hands on, then open it with MacIASL in its newest version you can find (Hint: Here is a good source) You can check if the version is new enough if MacIASL doesn't throw error upon compiling a freshly extracted DSDT.aml or DSDT.dst
       
      Add rehabmans repo (as per linked guide) and apply the following patches:
      Rename _DSM to _XDSM Fix _WAK Arg0 v2 USB3 _PRW 0x6D Skylake (instant wake) Find the CNVW device and remove the _PWR function there.
       
      Compile the DSDT and place it in "patched".
       
      2.2.2 Use SSDT hot-patching
      Instead of having to re-extract and re-patch the DSDT on every BIOS change or update, Hardware change one can also use ACPI hot-patching.
      It's a combination of config.plist patches and an SSDT, which is hot-patched into the ACPI (if I understand the process correctly)
       
      You need to add this SSDT-GPRW.aml to your Clover folder in the designated position at Clover/ACPI/patched You need to add this patch to your config.plist. It goes into the DSDT patch section  
      Note: This works for me, but the patch removes the _PRW method from all devices in the DSDT. This could have side-effects. So far, I have seen none. At the moment I'm also not applying any other patch, compared with the additional edits I made to the DSDT method before.
       
      2.3 Install kexts to system
      As mentioned in the install section, it's better to follow rehabman's instruction and install USBinjectAll.kext to /L/E:
      sudo cp -R Release/USBInjectAll.kext /Library/Extensions sudo touch /System/Library/Extensions && sudo kextcache -u / 2.4 Enable onboard Audio - Install AppleALC kext
      Make sure your EFI partition is mounted and that you have a vanilla AppleHDA kext available. See below for a guide how to get a vanilla AppleHDA if needed
      Note: Our Audio codec is ALC887 and it's running with layout ID 1.
      Download the newest AppleALC kext from here and install it together with lilu.kext from here into your usual /clover/kexts/others location. Done. No scripts or config.plist patches necessary.
      Add layout ID 1 to config.plist, if it's not there yet:
      <key>Audio</key> <dict> <key>Inject</key> <integer>1</integer> <key>ResetHDA</key> <true/> </dict> If you previously  installed any  audio patches, please follow this guide to "vanilla-ize" your install.
       
      2.5 Optional steps for Graphics
      If you have a dGPU, now it's the time to install its drivers and adjust the config.plist for it. The detaisl are specific to your GPU and thus of scope of this guide. Yet, my supplied config.plist is ready to be used with Nvidia Pascal cards and using the Nvidia web driver.
      Whatevergreen.kext helps with Intel iGPU and NVIDIA dGPU fixes.
       
      At the moment I'm also testing out a special bootflag: 'shikigva=12' to enable faster rendering in Final Cut Pro X. Without whatevergreen.kext and a shikigva bootflag, rendering in final cut seem very slow.
       
      2.5.1 Framebuffers
      If you're facing problems with output from your internal GPU, you can try the framebuffer patches listed by @BackwardMac:
       
      2.6 Install a proper keyboard layout
      You might not be using a fancy Apple branded keyboard. If you use a PC keyboard, you might be annoyed by the differing layout and usage of keys. As a German, you might find yourself quitting applications, since alt gr + Q won't add an @, but quit your current application. To fix this, you can simply install a different keyboard layout. Copy it to /Library/Keyboard Layouts/ and chose the layout in System Preferences, Keyboard in the section "Other". Deleting the previously selecting layout makes sure that only this one is used. Nice little trick.
       
      A keyboard layout for German keyboards is attached and works wonders
       
      3. Updating
      Updating inside 10.3.x/ 10.4.x point updates doesn't require much attention:
      Download the update from the AppStore as any Mac would do Allow the system to reboot Before booting MacOS with Clover, make sure to disable extra drivers for dGPUs which require non-native support. If using an Nvidia dGPU: Remove "nvda_drv=1"  from your boot arguments and disable Nvidia injection If using a non natively supported AMD card, do the same for AMD (I'm not using AMD, thus I cannot be specific) Boot into the newly created Install MacOS partition Repeat this process until the Install partition is gone Boot MacOS again, still following 3., and potentially install updated drivers Your Audio might require re-patching  
      4. ToDo
      Move away from static DSDT patching to SSDT hotpatching --> requires my work Native NVRAM --> requires developer work Audio without AppleHDA patching --> requires developer work  
      5. Thanks to

      I'm in the middle of my first hackintosh (High Sierra) on my ZenBook Pro UX501VW-US71 laptop using the Vanilla Install.

      Hi people,
       
      Installer to activate the sound card REALTEK ALC282-v2 (10ec:0282) with LayoutID 1 or 3 in MacOS. This installer does not contain AppleHDA patched Kext. To work properly, it must be installed over vanilla AppleHDA.kext.
       
      I want to thank the whole community for their efforts and content provided, because without these it would not be possible to create this installer.
       
      I would appreciate comments and suggestions!!
