Graphics Acceleration for Intel HD 4400 on Sony VAIO UltraBook Laptop

[sunstar]

Hello everyone,

I'd successfully installed macOS Big Sur 11.0.1 Beta on my laptop Sony VAIO UltraBook SVP1321WSNB using open core 0.6.2 as well as windows 10. 

Although, wifi, sound, bluetooth etc. everything works fine.  However, it's showing VRAM as 7 MB only as I believe frame buffer patching is required in order to have proper graphics acceleration.  

But i'm not sure how to proceed.  I have seen a topic related to video acceleration but unable to understand how to use it ?

If anyone can help my i would apreciate it very much.

 

My laptop configurations are:

- SONY VAIO UltraBook SVP1321WSNB

- Intel core i5-4200u

- Intel HD Graphics 4400

- 4GB RAM

- 128 GB ssd Samsung

Copy the properties and I have the same result.

Previously I tried, since the configuration is exactly the same as proposed in the guide. I don't understand what happens ...
