Hi, I get success in boot and instalation BIG SUR. But, acceleration graphics UHD 630 doesn't work...

looking for a solution, I discover that's need make a first thing: apply patch -->> GFX0 to IGPU...

but, making it, boot stuck on:


- AppleUSBXHCI start unable to get device memory

- failed to detect supported SUPERIO Chip


Whitout this patch, boot get sucess...

Using OpenCore


Your properties injection for iGPU are not only astonishing, they must also be wrong. Just start with the basics, i.e., ig-platform-id, fmbem and device-id. Ensure you use the correct values for UHD630 associated with your 10th gen Comet Lake CPU generation. You can look at patching the connectors in a later stage.
