Hello everyone,
This is my first post for this project.
I started a "research" to modify a Intel HD 3000 kext with Metal support.
The idea is simple: HD 3000 is very close to HD 4000 in VA Driver and GL driver (GL not much, but still some shared features). Based on this, I modify the HD 4000 Metal driver to HD 3000.
Is very primary with few hex modifications but I think this is possible.
In attachment is the modifications, is not functional yet (load the desktop but Finder not load). Have issues with signature for MTL Driver and I don't have test on the originals macOS Frameworks (only in patched). Also have in attachment the patched kext for MacbookPro8,1 AirDrop support, if anyone needs for this model (MacBook Pro 2011).
If anyone have this original files for macOS Catalina (without patch) and can send to this post, I will appreciate

(I know, I can extract of the pkgs files in macOS installer, is only for more speed and less work to me.. 😅). These files are:
- CoreDisplay.framework
- OpenGL.framework
- GPUSupport.framework
- SkyLight.framework
In the coming days I will continue with the research and testing in this kext.
