Roger Smith Posted November 10, 2019 Share Posted November 10, 2019 on my hd4600 machine I used WhateverGreen to patch AppleIntulAzulFramebffer to enable bigger framebuffer to enable 4K mode. The machine boots up fine up to the point when it gets to the apple logo. Then it changes from the 4K mode that my bootloader has enabled to one that is corrupt. I can change resolution using the display manager to 2K then up to 4K and everything is fine. Is there something is coredisplay that needs to be patched too or does anyone have any ideas? 1 Link to comment https://www.insanelymac.com/forum/topic/341096-booting-to-4k-resolution-hd-graphics-4600/ Share on other sites More sharing options...
