      So I have some less powerful hardware, that's why I'm installing High Sierra in 2020. Anyway, I'm trying to boot from the USB and I get the following errors:
      00:000 00:000 OCB: Missing DMG signature, aborting 00:585 00:585 OCB: LoadImage failed - Unsupported That's it. The logs begin and end there. The rest of the file is zeroes.
       
      Bootloader: OpenCore 0.5.9 Release
      Drivers:
      HfsPlus.efi
      OpenRuntime.efi
       
      Kexts:
      AppleALC.kext
      Lilu.kext
      RealtekRTL8111.kext
      SMCBatteryManager.kext
      SMCLightSensor.kext
      SMCProcessor.kext
      SMCSuperIO.kext
      VirtualSMC.kext
      WhateverGreen.kext
       
      ACPI:
      SSDT-EC.aml
      SSDT-HPET.aml
      SSDT-PLUG.aml
      Note: I used SSDTTime to make the DSDT dumps for this exact computer
       
      Hardware:
      Intel Core i3 (Haswell)
      An Intel VGA-Compatible Haswell iGPU
      An nVidia Geforce 920m GPU (part of the reason for installing High Sierra)
      USB: Intel 8 Series USB xHCI HC
      SATA: Intel 8 series SATA Controller
       
      If you need more details, here's my laptop https://www.asus.com/Laptops/X540LJ/ . I have the 512GB version with 4GB of RAM
       
      I found a lot of forum posts about people having the same error, except nothing solved mine. Also, I haven't found anything online about the error with the Missing DMG Signature.
       
      EDIT: If anybody needs my config.plist, feel free to ask for it and I'll happily post it

      So i managed to install latest Catalina with opencore 0.59 and latest acidanthera's work on my HP 840-g4. But i have just one annoying problem: IMEI.
       
      The issue is exactly the same as described here:
       
       
      and in other thread at the commercial hack site with big eyes.
       
      Most of the applications not responding after wake from sleep. crashed quicklookup, quicktime player, youtube, hackintool, etc, etc. (spinning color wheel).
       
      So surfing deeply on the forums, i noticed that the problem is related of lack of IMEI injection. So i tried manual HECI to IMEI patch, knowing that WhateverGreen do that work. No results.
       
      The only way that i can get IMEI on ioReg is changing the address from 16 to 0, through a ACPI patch:
       
      dict> <key>Comment</key> <string>HECI ADDRESS</string> <key>Count</key> <integer>0</integer> <key>Enabled</key> <true/> <key>Find</key> <data>SEVDSQhfQURSDAAAFgA=</data> <key>Limit</key> <integer>0</integer> <key>Mask</key> <data></data> <key>OemTableId</key> <data></data> <key>Replace</key> <data>SEVDSQhfQURSDAAAAAA=</data> <key>ReplaceMask</key> <data></data> <key>Skip</key> <integer>0</integer> <key>TableLength</key> <integer>0</integer> <key>TableSignature</key> <data></data> </dict>  
      So with this i can get IMEI on IoReg
       

       

       
       
      But i think that is a problem! Because the KBL FrameBuffer can't initialize the MEI Service, even with the IMEI at ioreg, this is from boot syslog:
       
      2020-06-24 16:38:29.075004-0400 localhost kernel[0]: (AppleIntelKBLGraphicsFramebuffer) <AppleIntelKBLGraphicsFramebuffer`AppleIntelFramebufferController::createMEIDriver()> [IGFB][ERROR ] Failed to start MEI service! 2020-06-24 16:38:29.075014-0400 localhost kernel[0]: (AppleIntelKBLGraphicsFramebuffer) <AppleIntelKBLGraphicsFramebuffer`AppleIntelFramebufferController::createMEIDriver()> [IGFB][ERROR ] Failed to create MEI service  
       
      Soooo, the question is:
       
      How can i solve this?!!
       
      I also tried:
       
      1. SSDT-IGPU from Rehabman
      2. SSDT-IMEI
      3. Rename HECI to IMEI ACPI patch
      All these with no luck.
       
      PD: I have to say that not SDcard mount after wake from sleep and this are the only two thing left to solve in order to get full working hackintosh laptop.!
       
       
      Thanks in advance

      Hey guys, I'm new here, so hello world!
       
      Here we go. 
      I have the following configuration:
      Gigabyte Aorus Master Z390 i9 9900K Sapphire Vega 64 Nitro+ Corsair Vengeance 64GB 3000Mhz Corsair H150i PRO (disconnected from the internal USB) Samsung Evo 970 1 TB - Catalina Install Intel 660p 1tb - simple storage drive  
      I have the latest Catalina version installed with OpenCore 0.5.8 Bootloader.
      I have followed the guide, and also relied on this EFI, since I have the same hardware: https://github.com/cmer/gigabyte-z390-aorus-master-hackintosh

      When idle the pc freezes - becomes unresponsive and my router disconnects from the internet (Archer C9, connected via PPPOE user/pass).
      Besides the freezing issue, which I’m not sure where it comes from, the internet disconnection just puzzles me. Any ideas?
       
      Things I tried so far:
       
      Reset NVRAM Disabled cfg lock Removed the BT BCM94360CS2 from the internal USB port (solved the sleep issue) Removed IntelMausiEthernet.kext and disabled the NIC in BIOS - saw some similar problems related to this Used Vgtab to generate the power table for the video card (Sapphire Vega 64 Nitro+)  
      Also, before OC bootloader is loaded I get this message, but otherwise boots normally:
      OC: Setting NVRAM 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:rtc-blacklist - Not Found
       
      I'll try replacing IntelMausiEthernet.kext with IntelMausi from Acidanthera, but I don't think it will make any difference since disabling the NIC and removing IntelMausiEthernet didn't do anything.
      Delete the entries from Add and Block in config.plist to remove the NVRAM error above - although since it boots I don't think it's related to my freezing issue.
       
      Any ideas?
       
      Thanks in advance!

      I'm trying to upgrade from Sierra to High Sierra. My Sierra is working and booting great with the latest Clover 5.0 r5115, but when trying to upgrade to High Sierra, any time the computer reboots into the installer, it gets stuck at the line "Start ReadKernelCache". The screenshot is attached. I've tried the following troubleshooting steps that I've read in other similar posts, none of which worked. It always remains stuck at that line:
       
      Boot with UseKernelCache=No and/or -x and or -f Temporarily remove discrete graphics card and try to install with integrated graphics Add MATS to the Drop Tables list in Clover Configurator Look for an option similar to "Above 4G Encoding". My motherboard doesn't seem to have that. Try a bootable USB drive with the High Sierra installer instead of the App Store mechanism. The USB boots great, and I can initiate the installation, but upon reboot, I get the same issue trying to boot into the installer.   Disable integrated graphics in the motherboard's BIOS    
      Below are my system details. It seems like it should be possible, based on this post, to run High Sierra with this motherboard and CPU, but I can't get the installer to run. 
      Thanks for any help!
       
      Motherboard: Gigabyte GA-Z77X-UP5-TH
      CPU: Intel Core i7-3770K
      Graphics: EVGA GeForce GTX 970 
      Clover: 5.0 r5115 with basically no mods from the default ISO aside from enabling APFS driver

      Hi,
      Below are the specs of the system:
      Gigabyte H61M-s 16 GB DDR3 RAM EVO 860 500 GB (APFS formatted) i3-3220 Zotac GTX 1060 6 GB GDDR5X (currently using HDMI) Dual booted with Windows 10 on a different drive Config.plist and EFI are at the bottom.
      I have been struggling with a very specific problem since months ago that I still haven't been able to find a working solution for. Before this, I had my hack running on High Sierra that was installed using the tonymac tools. Recently, I reinstalled the OS using the vanilla guide, and the problem is still there after installing the web driver (which I have done using this guide from Hackintosher). I have also tried different builds of macOS 10.13.6 and their corresponding webdriver, and the problem has been the same.
      I have the correct version of Nvidia web driver installed for my version of macOS. The installation was smooth and the Nvidia icon shows up in the status bar. Below, I have explained what happens with different settings.
      1. When the webdriver is disabled in clover, the system works, but obviously with tearing animations, stretched screen resolution and no GPU acceleration. The about section shows the graphics as "Display 5MB". The login screen consists of a plain grey background. Just how it is when you freshly install the OS with non AMD GPUs.  
      2. Now, when the webdriver is enabled in clover and the system is booted, after the apple logo, the screen turns off for a second (to switch resolution), turns back on with the login screen at correct resolution and blurred HS background (like it is supposed to), then shows the shut down screen, then a black screen with cursor in corner, then back to login screen...this goes on and on while the keyboard and mouse are unresponsive. Here's one of the threads I was able to find on similar problem. YouTube link for the video that I have recorded of my screen. The weird part is that this exact thing happens even when the macOS is setup to login automatically, i.e. it displays the frozen login screen with the password field.   3. When the webdriver is enabled along with safe mode in clover, the screen resolution gets fixed and the monitor name is also detected. The about section shows the graphics as "Nvidia Chip Model 6143 MB". But there's still no GPU acceleration and this time, the Nvidia icon is missing from the status bar. This is the closest that I have been able reach to success.   4. When the webdriver along with "Set Nvidia to VESA" is enabled in clover, the system boots up, Nvidia icon is visible in the status bar and when clicked, shows that the webdriver is enabled. But everything else is the same as when the web driver is disabled, as shown in the 1st point above, except that the about section now displays graphics as "Nvidia chip model 5 MB".   Could anyone please help me out? It has been many months and I am now tired of trying and failing. I am completely lost at this point. I have seen so many posts from people with a fully working GTX 1060 on their hacks, yet I am unable to get mine to work. I am guessing it's just an incompatibility problem with my specific version of GTX 1060. Or may be it is just a problem on the software side? Maybe it's just a missing kext, or a single line of code needs to be changed in config.plist? I am also taking into consideration that it could be a problem with HDMI because I haven't yet been able to test out any of the 3 DisplayPorts that the GPU has, due to lack of a DP cable.
      I would be really grateful if anyone is able to help me out with this.
