Well, I know what you met.

Usually, if we add -v in boot-args, we can see that 'stuck at Apple logo' is the same as 'stuck at EB|LOG'.

Try the following:

Also, because I have changed the DVMT-Preallocated to 64MB by patching BIOS, so I didn't write the framebuffer section in config.plist, so you may need to pay more attention to DeviceProperties -> PciRoot(0x0)/Pci(0x2,0x0).

Please star this repo and follow me if this helps you.
