(XPS 15 9500) Stuck on Black/Verbose Screen After Enabling Integrated Graphics Acceleration


I'm currently experiencing issues enabling GPU acceleration for my Dell XPS 15 9500 Hackintosh build. I've used whatevergreen to disable my dGPU (Gtx 1650 ti) in boot args and configured my config.plist to use integrated graphics.

The problem is whenever I attempt to boot without using the boot argument -igfxvesa to disable GPU acceleration, I either get stuck at a black screen after booting or am locked on the verbose boot screen with the message 'gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0' .

I've read here that this occurs with 4k@60Hz display panels when GPU acceleration is enabled without using the boot flag -igfxmpc or adding the property enable-max-pixel-clock-override to the pci entry in config.plist, but even after specifying both of these i've still had no luck.

Any help would be greatly appreciated!

Model Dell XPS 15 9500 (2020)
CPU Intel I7-10750H
iGPU Intel UHD 630
Display 3840x2400 4K@60hz Touch Display


Running MacOS Big Sur 11.0.1 with OpenCore

Update 1: I can still hear feedback from input keys despite the graphics not working, so chances are that MacOS is still booting perfectly fine, just with no graphics.
