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.
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
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
I have been using clover to install and configuration my Hackintosh High Sierra 10.13.6. It's been a struggle and a pain. Can't restart/shutdown/wake from sleep. Random freezes. When freeze happens mouse works but in loading state. UI and open apps freeze not the mouse. I can make the apps smaller and move them.
I haven't used any DSDT nor SSDT. Tried 5 or 6 of them from others but sometimes i end up not booting. Could someone explain me do i even need them and why? Do i need DSDT or SSDT or both?
I'm going to try to install everything OpenCore. The first thing is i can't use a method that needs an internet while installing MacOS cause my ethernet/internet only works when i install MacOS. So i can't use the images i need full installation. Okay i have the full installation for 10.13.6. I need to use a version 10.13.4-6 versions cause application Sketch needs the newer one High Sierra 10.13.4++ version.
Can you tell me? Can i use same kexts from Clover on OpenCore? Secondly how can i install full USB MacOS installer? (High Sierra 10.13.6 version i have is 7gb i think thats it) Is there a version of AMDHigh Sierra version made from the community for 10.13.4++ version? If i use the normal 10.13.6 High Sierra should i use this AMD 10.13.6 Kernel when i have installed the MacOS or some other kernel that's better for my system? https://github.com/Shaneee/AMD-High-Sierra-XNU/releases Whats the best version of High Sierra to use for Ryzen and Nvidia system?
