Hello everyone, I want to know if someone could help me solve my problem. I have installed MacOS Sierra and Mac OS High Sierra,both of them in different hard disks.
 
Almost everything works fine, except my Intel HD Graphics 5500 card, I only have 7 MB in macOS as shown.
 
I found a solution on the Internet where I should change the DVMT value from 32 MB to 64 MB in my BIOS. I unlocked my BIOS to do it but I have the same problem.
 
In this forum, the user Fatboy was able to do it in his laptop DELL E7450 with the help of users Klaus, Jake and Herve and now I want to know if anyone could help me.
 
My last update of attempts to solve my problem:
 
I have VRAM in my video graphics but with some problems. I discovered that I had to  activate Load VBios in the graphic item.
 
I have set ig-platform-id to 0x16260006 and kext patch
 
Name: AppleIntelBDWGraphicsFramebuffer
Find: 06002616 01030303 00002002 00005001
Replace: 06002616 01030303 00003001 00009000
 
Name: IOGraphicsFamily
Find: 0100007525
Replace: 010000eb25
 
When I turn on my laptop sometimes i get a kernel panic like a crossed out circle and then try and try again until the system activates, but I can not see almost anything because I have a blinking graphic. Then, I switch to sleep mode and I activate it afterwards and in that moment I can see almost everything well, except screen brightness.
 
Could someone help me?
 
I want to know how to get 
screen brightness
output port like vga and hdmi
battery status
control keys brightness
and some issues more ...
 
PD. When I do not use my system for 5 minutes aprox my system restart automatically, That problem started when I activated Load VBios in graphic item.
 
I attached photos and screenshots and my debug report.
 
Thanks in advanced.

Your DSDT/SSDT are not patched correctly, lots of errors still. There errors in your Config file 

Get rid of VoodooHDA, NullCPUPowermanagement, AtherosE2200Ethernet, IntelMausiEthernet

 

Add Lilu.kext to /EFI/Clover/kext/Other

Delete folder kext/10.13, only need Other

 

Try booting with this Config 

config.plist.zip

The IOGraphicsFamily patch for High Sierra differs from El Capitan and Sierra. It is:

Find:       0100007522
Replace by: 010000EB22

If you use the wrong patch, you risk a KP...

 

Why do you enable "Load VBIOS" in Clover config? What VRAM problems does this solve?

Hi Jake Lo, I eliminated all your suggestions and I used your config.plist modified. When the system start, this delay around 10 min to arrive to the desktop, before that I have the same blinking graphic, and I switch to sleep mode and I activate it and in that moment I can see the desktop.

 

Tell me Bro, How to patch my DSDT correctly, I got it extracting from windows with RW-Everything directly and copied to my patch folder into ACPI.

 

Thanks in advanced.

 

PD. Attached my current debug report after apply your suggestions.

OK. I started Clover GUI and attach my origin folder zipped
 
My complete specs of laptops is :

  • Intel Core i7-5500U
  • Intel HD Graphics 5500
  • nVidia GeForce 840M
  • Conexant SmartAudio HD
  • Qualcom Atheros QCA61x4 Wireless Network

  • Realtek USB 2.0 card reader

 
My BIOS version is ABCN96WW InsydeH20, this was extracted and modified thanks to help of SPI Programmer device that I bought  and the bios-mods.com site. I did it to unlock hidden settings to change DVMT graphic.
 
PD. Attach my AIDA64 complete hardware report
