    Can't install High Sierra on Inspiron 5558 Broadwell

    Thanks Jake, it works great! Much appreciation. Now I'm curious about how it can be done. I was trying to fix it using this approach, but I had to uncheck "Drop OEM" and delete patched files so there is SSDT-DiscreteSpoof.aml file only in patched folder, and it worked and I managed to boot with Nvidia enabled, but of course, everything else wasn't working. Then tried this one, I patched SSDT-5 to call _OFF form _INI, and there wasn't EC call, so nothing else to do, then added SSDT-5 and SSDT-6 (as it has _OFF implementation) to patched folder and config.plist in SortedOrder, but without success, and it stuck at "Legacy Shim", where did I go wrong?

    5558IOReg.zip If I updated the BIOS, should that generate cleaner/better coded tables? or it isn't related or wouldn't differ that much?

    I have disabled Nvidia again and tried 5558_A14_disableFromBios.zip and it worked great, even though installer crashed in the second step of installation, but rebooted and tried again and it gone well. But for sure I can't boot when Nvidia is enabled, is there any solution for this??

    Disabling Nvidia from BIOS caused weird problems, the Switchable Graphics checkbox disappeared next time I entered the BIOS settings to enable it, I reseted the BIOS to defaults hoping that it will fix the problem, and it fixed it, but windows boot manager disappeared from boot options (I have windows 10 installed), so I couldn't boot to windows, that was unhappy moment, but I boot to the USB and luckily there was an option there has "windows" with .efi file on it, but no "windows boot manager", I chose it and got to boot to windows, restarted the device, and windows boot manager was there again. So, is it possible to patch the files with Nvidia enabled? Thanks Jake for your time, I really appreciate it.

    Nvidia was disabled via BIOS, I have enabled it and generated the files again origin.zip. The previous files are generated when it was disabled.

    These are my ACPI origin.zip files generated by clover, and High Sierra version that I have is 10.13.3 (does it matter?). Anyway, I hope that will help.

    I stuck here. I was using the latest version (5.1.3.1).
  9. Hello, I have been trying to install High Sierra on my Inspiron, but without success. After booting to clover then choosing the installer, it stuck on Apple logo, I tried again with verbose mode and I got error like this one: I was following this guide, but I couldn't update the Sierra bootpack properly, I only made FirmwareFeatures=0xFC0FE137 and FirmwareFeaturesMask=0xFF1FFF3F . There is no FixHeaders nor USB port limit patches on clover configurator. I used the generic EFI folder, 5558_920M-Disabled_A14.zip and Lilu.kext & IntelGraphicsDVMTFixup.kext . Hardware specs: CPU: i5-5200U Audio: Realtek ALC3234 GPU: Nvidia 920m (disabled), Intel HD Graphics 5500 BIOS Version: A14 BTW, I installed Sierra without any problem by following the guide, a lot of things working, battery percentage, ethernet, keyboard hot keys, brightness control, touchpad gestures and multitouch. But audio and webcam aren't working. Thanks.
