Hi

 

Need help please!

 

I've issue with latest WEG 1.3.0 on my config i7 9700K - RX 580. See image in attachment

 

Catalina start only if I block WEG with Clover

 

Any solutions

Im on Dell XPS 9560. Kabylake. Intel HD 630 (591b0000). I have a 4k. The bootloader gets to the point of loading graphics acceleration to load the desktop, then never loads the desktop. It's just stuck in verbose black screen. I hear when i press buttons that the desktop is loaded, but im not able to see it. I have the latest Whatevergreen 1.3.0. I use the same Clover bootloader folder to load Catalina dp1 on its own partition and it loads. So, I don't know why it will not get me to the desktop in dp2. Adding "12345678" to ig-platform-id and fake graphics id only leads to a panic and reboot. The only way i get to the desktop (without acceleration) is in safe mode (-x). Can this be worked out in the next build or does it seem like something thats not related to Whatevergreen?

Can you post the compiled new WEG? Or you can compile yourself? If it's download-and-compile-done process I would be more happy do it myself.

 

Update:

It seems quite easy to compile those kexts. Here it is if anyone needs

Lilu+WEG.zip

New WEG in attachement

 

If you want to compile by yourself:

 

  • Download Lilu master from Acidanthera in Github
  • Compile latest Lilu.debug (Xcode)
  • Download Whatevergreen master from Acidanthera in Github
  • Put Lilu.debug in your  Whatevergreen folder
  • Compile WEG (before edit scheme to release) in Xcode

 

Sorry about my bad English

1.3.0 (RELEASE).zip

You don't need -lilubetaall as boot argument,, Lilu.kext and all plugin are compatible now with Catalina DP2. Just reCompiled all Lilu.kex and plugin :)

Yes, you're right. All my kexts are up to date :) The first WEG 1.3.0 don't work on my config i7 9700K. The developer add new commit for 1.3.0, 5 days ago. With this new WEG 1.3.0, there is no more panic in my system.

First make git clone many github source into one directory, eg "ManualBuild"

After that open your terminal and "cd ManualBuild" press enter, then type "find . -type d -depth 1 -exec git --git-dir={}/.git --work-tree=$PWD/{} pull origin master \;" and press enter,, automatic check now :)

Hello, I have an issue which I wonder if could be fixable via WhateverGreen, or at least maybe an idea of what's going on.

- My system is a Z390, with an Nvidia card. Both iGPU and NVIDIA are enabled via BIOS. Primary card set is iGPU.

- I have a displayport switch, that helps me connect the monitor to one of the GPUs.

- With iGPU selected via the switch, after rebooting or shutting down from Windows, when system reboots or turns on, POST appears normally via iGPU. So far so good.

- For OSX, I disabled NVidia (using WhateverGreen, or DSDT - I tried both methods), as no driver is available. After rebooting from OSX (booted with iGPU), system reboots successfuly (I hear the startup "beep"), but no POST appears via iGPU. This will persist even if I turn off the system and turn it back on. I must switch to nVIDIA to see POST.

However this happens only after OSX was loaded. Any idea what's going on?

Hi

 

If I disable my Optimus graphics card with disable-external-gpu property, I don't have any video output through my usb c displayport (connector-type in ioreg seems correct: 00040000).

With Nvidia GPU enabled, I see the external monitor at display @1 under IGPU@2, so the port is wired to the integrated GPU.

The only difference between the two configurations is the one line used to disable the DGPU.

I attach ioreg + log with both DGPU on and off along with my config.plist and kext folder.

Laptop specs:

Dell G3 8750H with Intel UHD 630 + GTX 1060 MaxQ

Let me know if you need more info.

Hi! I have a lenovo kaby lake laptop. Framebuffer set to 32mb in bios and can't be set higher. Bios is locked and rewrite protected. Framebuffer memory is also set to 32mb with whatevergreen. Does minstolensize patch still work since that was the (only) way to enable 4k30 output before whatevergreen or is there an alternative way to enable 4k output? -cdfon boot flag doesn't do anything and graphics memory is already set to 2048mb.

I use IGPU primary despite of my RX580 connected to my monitor: now without issues (panic). Can you post screenshot so WEG developers answers to you.

for those who have problems with ATIController::TestVRAM crashes during boot, i've created a patch for clover for solving this problem. second patch removes magenta-colored lines which appears at screen during video driver startup.

Insert this is KextsToPatch section.

PS: patch is beta version, tested only with 10.14.5 + Vega64, but must be compatible with any AMD card.

 

TestVRAM fills memory with 0xaa55aa55 bytes (it's magenta pixels you see at screen), and it's tries to test too much of address space, writing this bytes to framebuffer memory. If you have verbose mode enabled (as i have), there are possibility that framebuffer will scroll during this test, and TestVRAM will write 0xaa55aa55, but read 0x00000000 (because magenta-colored pixels are scrolled up).

previous lilu 1.3.7 + WEG 1.3.0 are no problem.

 

lastest other kexts source are no problem. now only WEG happens this issue.

      Hi, anyone here got those problems like me ? When I click play, the film load nothing, just show blackscreen like this (attached) or when I download an episode to the computer, it shows error (err = -11800)

      Anyone here knows a fix ? Maybe a bug or problem from Hackintosh ?

      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.
       
      /!\NOTE: There have been reports saying that using this method (switching SMBIOS to a MacPro one) with newer versions of MacOS may cause iTunes to crash.
      So...keep that in mind and better try some of the other methods mentioned here.
       
      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.
       
      UPDATE:
       
      According to Vulgo, NoVPAJpeg.kext is now deprecated.
      In case its functionality is needed, use WhateverGreen.kext (alongside Lilu.kext) and add the following boot arguments:
      shikigva=32 shiki-id=Mac-7BA5B2D9E42DDD94 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 (tested on my old MSi GTX 650)
       
      This is what I needed for my NVIDIA GPU and the MSI motherboard in the signature (*since then, I upgraded my GPU to my current RX 580). 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!

      - 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 BCM94352Z card (you will have hand-off Bluetooth too), just install the kexts (enabled with BrcmFirmwareRepo.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 Catalina install zip (bootpack & postinstall): acer_aspire_V591G-55TU_cata.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!
      On Catalina the System folder is read-only, so you need to remount in rw to modify System/Library. 
      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.
       

      Elan SmartTouchpad
      I only use scrolling, one-, double- & tripletap
      If you want to try other gestures go to this link for more informations, options (v4.6.5) ->  DETAILS ABOUT THE SMART TOUCHPAD DRIVER FEATURES
      Fn Brightness keys not working with this, tried several things without success. With VoodoPS2Controller it's working, but you'll have no gestures (neither scrolling).
       
       
      Before updating to a new version of Catalina 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)
       
      Catalina & 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)!

      Hi!

      Could anyone help me installing High Sierra on this system?
      I succesfully installed Sierra before on this system with help of Jake Lo (thanks!!), I just wondering if could High sierra possible to installed on this system?
      Boot stopped at this. I'll attach my Clover folder and a picture from boot.
      UEFI enabled, and for skylake I used IntelGraphicsDVMTfixup and IntelGraphicsFixup kexts. My bios is very limited and does not have any option to change dvmt prealloc or anything else.
      Everything works fine on Sierra.
      Here is my system:

      *REUPLOADED updated CLOVER folder, attached as "v5_591g_55tu_updated_CLOVER.zip" (uploaded to OSXLatitude forum, can't upload here).
       
      I'm using High Sierra in Dual-boot with Windows 8.1. To do this in a clean install or with Windows installed first try my little minimal guide:
       
      Dual-boot clean install (on one drive):
      1. Boot into your Mac installer, Create 2 partitions in GUID table (1 for Win (I used FAT32 but I think it's no matter what), 1 for Mac), 
      2. Install Mac, boot with your USB, *mount your EFI partition (use terminal or an EFI mounter app), create an EFI folder, copy the CLOVER folder I attached to the EFI folder, restart,
      3. Boot into your Win installer, Format the partition you created for Win, install. 
      4. 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):
      If you already have Windows and you don't want to lose all your data there is a hope:
      You need bootable Mac Installer and a full system restore image (you can search for it).
      (You may see errors if your EFI partition is not 200 MB)
      1. Boot into your Windows, resize your partition or create one for Mac.
      2. Boot into your Mac installer and in Disk Utility format the partition you created.
      3. Restore from image: select your full system restore image.
      4. When it's finished restoring you just need to restart, then boot to the system with your usb.
      5. Do Step 2. from "*" from clean install dual-boot above. but KEEP "Microsoft" FOLDER IN IT!
      6. Do Step 4. from clean install dual-boot above.
      7. You're done! You can select your old Windows and your new macOS!
      (I 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 The best version for restore method is Windows 8.1. It's using 200 MB EFI. Windows 10 using 100 MB EFI and will annoy the Mac restore. You can use with Windows 10, just ignore the errors IF YOU GETTING ERRORS DURING WINDOWS INSTALLATION (could not be formatted, etc):
      Make sure you have GPT partitions, and GPT installer 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, for that open cmd 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, to manage files download totalcmd or explorer++ (run as admin)) remove letter=b (This will "unmount" your EFI) Here is a video from dual-boot with Windows installed first (on one drive):
