poisson-myfish Posted July 2, 2020 Share Posted July 2, 2020 (edited) 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 Edited July 2, 2020 by poisson-myfish Link to comment Share on other sites More sharing options...
