[EFI] [AN515-44-R4KA] Don't start boot Dmg

[kaynnan]

Hello everyone,

I am trying to install macOS on my Acer Nitro 5 (AN515-44), but I am persistently stuck at the [EB|LOG:EXITBS:START] line. The system freezes right after selecting the installer from the OpenCore menu.

Hardware:

• Laptop Model: Acer Nitro 5 AN515-44
• CPU: AMD Ryzen 5 4600H (Renoir, 6 Cores)
• iGPU: AMD Radeon Vega (Renoir)
• dGPU: Nvidia GTX 1650 (Disabled/Unsupported)
• Bootloader: OpenCore (latest version)

The Issue:OpenCore loads, I see the boot picker, but when I select the macOS installer ("FAT external"), it scrolls through some logs and halts at [EB|LOG:EXITBS:START].

I noticed some errors in the log regarding OS.dmg.root_hash right before the freeze:[EB.LD.OFS|OPEN!] Err(0xE) <"usr\\standalone\\OS.dmg.root_hash">[EB.RH.LRH|P!] Err(0xE) <- EB.LD.LF

What I have tried so far:

1. Added SSDT-CPUR.aml to ACPI (and enabled in config).
2. Applied AMD Vanilla Kernel Patches (modified the core count patch for 6 cores: B8 06 00 00 00 00).
3. BIOS Settings: Secure Boot disabled (set Supervisor Password to disable it), Fast Boot disabled.
4. Tried different combinations of Booter Quirks:
   
   • SetupVirtualMap: Tried both True and False.
   • EnableWriteUnprotector: False.
   • RebuildAppleMemoryMap: True.
5. Added npci=0x2000 (and 0x3000) to boot-args.
6. Kernel Quirk ProvideCurrentCpuInfo is set to True.

Log Output:
