Ahmed Osama Posted July 11, 2018 Share Posted July 11, 2018 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. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted July 11, 2018 Administrators Share Posted July 11, 2018 If you use one of the latest versions of CC, you'll see the FixHeaders parameter in the ACPI tab. Link to comment Share on other sites More sharing options...

Ahmed Osama Posted July 12, 2018 Author Share Posted July 12, 2018 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. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 12, 2018 Moderators Share Posted July 12, 2018 directory is a mess, seeing duplicate SSDT and not see any related to Nvidia card. Clear the Origin folder. Extract new Origin folder again for patching. Link to comment Share on other sites More sharing options...
Ahmed Osama Posted July 12, 2018 Author Share Posted July 12, 2018 Here it is origin.zip. Link to comment Share on other sites More sharing options...
Ahmed Osama Posted July 12, 2018 Author Share Posted July 12, 2018 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. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 12, 2018 Moderators Share Posted July 12, 2018 ok, didn't know you could disable it from BIOS. Go ahead and disable it and use this patched from that Origin folder 5558_A14_disableFromBios.zip 1 Link to comment Share on other sites More sharing options...
Ahmed Osama Posted July 12, 2018 Author Share Posted July 12, 2018 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. Link to comment Share on other sites More sharing options...
