[solved] Intel HD Graphics 520 on macOS High Sierra showing black screen Dell Inspiron 5559 (2016)

[RAFFAY]

Hi guys, I have installed macOS High Sierra 10.13.2. I have everything working except the graphics. I have integrated Intel HD 520 card (no dedicated GPU) and CPU is i5-6200U. I have tried platform id 0x191b000 but I get a black screen during boot. I have also tried various platform-ids but get the same result. It remains as it is. My keyboard is working but screen is off/black. I can only boot by disabling the graphics, by using platform id 0x12345678. Please help me...

Can you tell me how to check my DVMT realloc size to see whether I have 32 or 64MB?

Most laptops default to 32mb.

Not a guide. Moved to laptop support.

The profile fields Mobo/CPU/Graphics are free form text.
Do not use the signature. And do not use build signatures.
Read the FAQ carefully.

Sorry. Now I have filled the information. Please help me in this regard. The guide I have followed, that person didn't get the error. I have asked him but he said, he can't sort this out. That is why I am here, hoping someone will help

Mobo is missing laptop 'make'.
Graphics is missing screen resolution.

Working around 32mb DVMT-prealloc is covered in the guide.

Ok. I have updated the profile.
So what I understand from the linked guide is that I will select a config.plist from the repository. My Graphics is HD 520 so I will select it. Then I will enable the patch like this:
<dict>
<key>Comment</key>
<string>0x19160000/etc, 32MB BIOS, 19MB framebuffer 9MB cursor bytes (credit RehabMan)</string>
<key>Disabled</key>
<false/>
<key>Name</key>
<string>com.apple.driver.AppleIntelSKLGraphicsFramebuffer</string>
<key>Find</key>
<data>AAAgAgAAUAE=</data>
<key>Replace</key>
<data>AAAwAQAAkAA=</data>
</dict>
Here I will replace Disabled to Enabled and move it to clover. Then I will rebuild the cache.
Am I right? This is my first encounter with DVMT and the like so please explain this to me if I am wrong.

The patch is already enabled (Disabled=false).
As per guide, must use invalid ig-platform-id until post install (because you must rebuild cache before the patch can work).
