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
Note: I used SSDTTime to make the DSDT dumps for this exact computer
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: (AppleIntelKBLGraphicsFramebuffer) <AppleIntelKBLGraphicsFramebuffer`AppleIntelFramebufferController::createMEIDriver()> [IGFB][ERROR ] Failed to start MEI service! 2020-06-24 16:38:29.075014-0400 localhost kernel: (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
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.
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
