Ati Mobility Radeon HD4570 on Mavericks

[Rodrigo26]

Hi,

 

I installed Lion on my notebook (Dell Studio 1555) withno problem. Graphics works with qe/ci using custom framebuffer and dsdt.

Now I updated to Mavericks, boot with no problems, but qe/ci doesn't work, using same framebuffer and same dsdt... All i get is scrambled screen.

I don't know what else to try, can you please help?

 

Thanks!
