1. Ready to install

1. Install the VirtualBox software on your computer. After that, click on the VirtualBox extension pack file you downloaded

https://download.virtualbox.org/virtualbox/6.1.12/Oracle_VM_VirtualBox_Extension_Pack-6.1.12.vbox-extpack

2. Clicking on the extension pack will open VirtualBox on Windows and a window will pop up prompting you to install it. Click Install to complete this step

3. You have successfully installed the extension pack. You are now ready to create a virtual machine. Click New in the VirtualBox software

4. Here, provide a valid name for your virtual machine. For example, "macOS Big Sur" is as shown below. Make sure Type is set to Mac OS X and select the 64-bit version. When you're done, click "Expert Mode" to continue to the next step.

5. In this step, you will select the memory size or RAM that will be allocated for the virtual machine. It is recommended to set half of the total system RAM for the guest operating system. Make sure "Create a virtual hard disk now" is selected, then click Create.

6. Now, use the slider to set the virtual hard disk size to your liking. Although it depends on how much storage space is available on your computer, we recommend that you allocate 100 GB to your virtual machine. Select "VMDK (Virtual Machine Disk)" for the hard disk file type, and click "Create".

7. Now, click on Settings in VirtualBox as shown in the screenshot below

8. Go to the "System" category and click "Processor" in the top menu. You will be able to use the slider to adjust processor allocation. It is recommended to allocate half the number of processor cores to the virtual machine. Remember, if you have a 4-core/8-thread processor, it will show up as 8 CPU cores in VirtualBox. In this case, you can set 4 cores for the processor allocation.

9. Next, click on Display in the left pane and move the slider all the way to the right to Video Memory.

10. Now, go to the Storage category and click on Empty under Storage Devices. Then, click the disc icon on the right and select "Create Virtual Disc" from the drop-down menu.

11. You can click Add to browse the macOS Big Sur ISO file downloaded using File Explorer. Select the ISO file and click Select.

12. Now, click OK to exit the VirtualBox settings and close the VirtualBox application.

13. Open the Command Prompt on your PC. Be sure to run Command Prompt as an administrator.
