Bigsur 11.4 hang at boot

[ds2k5]

Hi, most times the system hang at boot with BigSur 11.4. Som times it boots. How to see what is wrong ?

first of all, please check your hardware list whether it's fully same as mine. https://github.com/badfellow/Hackintosh_M4800/tree/master/OpenCore

if yes, you may double check the PCI list whether hardware address is same.

if not, please check the log what stuck the boot (mostly it's hardware driver compatibility issue)and then you would be able to find the way to fix the issues.

Pay attention to your wifi adapter and GPU which not same as mine.

01:00.0 VGA compatible controller: NVIDIA Corporation GK106GLM [Quadro K2100M] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GK106 HDMI Audio Controller (rev a1)
03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)

The key is that your WIFI adapter is intel 7260. you must remove below 4 kexts from my EFI package and replace to appropriate Intel driver. In the meanwhile, you need to remove line 1379-1408 in dsl file SSDT-Dell-M4800.dsl, and then recompile to replace SSDT-Dell-M4800.aml.

AirportBrcmFixup.kext
BrcmBluetoothInjector.kext
BrcmFirmwareData.kext
BrcmPatchRAM3.kext

For other kexts, you could use my kexts in EFI package but please DO NOT upgrade to officials because some of my kexts have some modifications to adapt ACPI structure.

Thanks a lot! Not it works fine!

iasl SSDT-Dell-M4800.dsl cp /mnt/EFI/OC/ACPI/SSDT-Dell-M4800.aml

cp airportitlwm.kext to /mnt/EFI/OC/kexts with Clover Configurator: add the airportitlwm.kext v1.3 to kexts
