Install MacOS Big Sur on VirtualBox | Issues fixed 2024 

Try the following: Check VirtualBox Settings: Open your VirtualBox settings for the macOS virtual machine. Go to the System section. Under the Motherboard tab, ensure that the EFI option is enabled. Save the settings and try booting the VM again. Create a Startup.nsh File: If the issue persists, you can create a startup.nsh file within the EFI shell to manually load the bootloader. Follow these steps: When you see the EFI shell prompt, type exit and press Enter. You’ll enter an EFI text-mode GUI. Select Boot Maintenance Manager and click. Choose Boot From File and click. You’ll see a list of entries (PCI bus paths). Look for the bootloader (usually named boot.efi). Load the bootloader by navigating to its location and executing it. Additional Tips: Sometimes, changing the chipset to PIIX3 might help. Try booting with this setting. If you encounter a message that the platform is not supported, consider using a lower version of macOS that is compatible with your hardware. AMD Processors: Note that running macOS guests on non-Apple hardware with AMD processors can be challenging due to compatibility issues. Some sources suggest adding the following command to your VM configuration: VBoxManage modifyvm "mac" --cpu-profile "Intel Core i7-6700K" Replace "mac" with your virtual machine name. Remember that macOS virtualization on non-Apple hardware can be tricky, and results may vary. If you continue to face issues, consider exploring alternative methods or seeking specialized forums for further assistance.
