Do not hesitate to open an exit in case of a problem or for any technical question.

Prerequisites

VirtualBox

Go to this website and download VirtualBox and the Extension Pack.
Once downloaded, install VirtualBox and the Extension Pack.

Required files

All the necessary files except VirtualBox, the Extension Pack and the macOS ISO are available by downloading the repository.

Download the ISO of macOS Catalina 10.15 (8.3GB).
Download the VMware Tools.iso file.
Download the Boot.vmdk file.

Activate the Virtualization Technology

The virtualization technology is available for Intel and AMD processors under different names. For Intel, it is named VT-X and for AMD, it is named AMD-V. This technology must be enabled in order to run macOS Catalina on VirtualBox.

To activate the virtualization technology option, you need to access either the BIOS or the UEFI of your computer. In order to do this, you need to know the key·s required when booting your PC. It can be one of these keys: F1, F2, F10, F12, or DEL (may require pressing the Fn key).

How to activate Intel’s VT-X virtualization technology?

Once on your BIOS or UEFI, you need to find the Virtualization Technology, VT-X or VT option which is usually found in the Advanced options. Make sure you set this option to Enabled.

How to activate AMD’s AMD-V virtualization technology?

Once on your BIOS or UEFI, you need to find the Secure Virtual Machine Mode, AMD-V or SVM Mode option which is usually found in the Advanced options. Make sure you set this option to Enabled.

How do I know if virtualization technology is enabled on my computer?

Open the Task Manager and in the Performance tab check the Virtualization field is enabled.

Configuration of the virtual machine

Run VirtualBox.
Create a new virtual machine. Enter the name you want, select Mac OS X for the type and Mac OS X (64-bit) for the version.
Select the amount of RAM. The minimum is 4096MB, but for best performance, I recommend setting it to 8192MB.
Create a VDI virtual disk with a fixed size and a minimum of 80GB.
Click on your virtual machine and open the Settings options.
- In System ➜ Motherboard, set the Chipset to PIIX3.
- In System ➜ Processor, set the number of CPUs to a minimum of 2.
- In Display ➜ Screen, set the Graphics Controller to VMSVGA.
- In USB, enable the USB controller and check USB 3.0 (xHCI) Controller.
- In Storage, click on the disk button with a green + and add the macOS Catalina ISO file.
- In Storage, click on the hard disk button with a green + and add the Boot.vmdk file.
Click OK to confirm the changes.

Open a command prompt as administrator and type these commands:
Make sure to replace the Virtual Machine with the name of your virtual machine.

cd "C:/Program Files/Oracle/VirtualBox/"
VBoxManage.exe modifyvm "Virtual Machine" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage.exe setextradata "Virtual Machine" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"

Do you want to run macOS Big Sur on a Windows 11/10 PC? If you can’t afford to purchase an Apple Macbook, you can use it on a virtual machine using VirtualBox.

Before installing macOS Big Sur on a Windows PC, let you know; it is not a tough job. VirtualBox has made everything easy for you. With VirtualBox, you can install multiple operating systems on a single computer and seamlessly switch between them when you desire. The guest operating systems run within an application, virtualizing the hardware, and the OS doesn’t know the difference. In this gearupwindows article, we will guide you on installing macOS Big Sur on a Windows machine.

What are the requirements to run macOS in VirtualBox?

Before you get started, you’ll need to download the following files:-

VirtualBox for Windows
VirtualBox Extension Pack
macOS Big Sur ISO

How to Install macOS Big Sur Using VirtualBox on Windows 11/10?

Once you have downloaded the files as mentioned earlier on your Windows machine, do the following steps:-

Step 1. Install VirtualBox and then its Extension Pack, which you already downloaded.

Step 2. Now, open Oracle VM VirtualBox from its desktop shortcut by double-clicking on it.

Step 3. Click New.

Step 3. Type macOS Big Sur for the virtual machine name and then click the Expert Mode button.

Step 4. Next, name the operating System macOS Big Sur. Use the slider to increase the memory size up to 8GB if your PC allows it. If not, then let at least 50% of physical RAM. Then make sure “Create a virtual hard disk now” is selected and click on the Create button.

Step 5. Again use the slider to set the virtual hard disk size according to your preference. Although this depends on how much free storage space you have on your computer, we recommend allocating 60 GB for the virtual machine. Select VMDK (Virtual Machine Disk) for the hard disk file type and click the Create button.

Step 6. When you’re done, click Settings.

Step 7. Select the System category and then click the Processor from the top menu. Again use the slider to adjust the Processor allocation. It’s recommended to allocate half of your Processor’s core count for the virtual machine.

Note: If you have a 4-core/8-thread processor, it will appear in VirtualBox as 8 CPU cores. In that case, you can set 4-cores for processor allocation.

Step 8. Now, click the Display category from the left sidebar. On the right sidebar, move the slider under the “Screen” tab of “Video Memory.”

Step 9. Now, select the “Storage” category and click on Empty under the Storage Devices section.

Step 10. Click on the optical disk icon on the right sidebar and choose “Create a Virtual Optical Disk” from the dropdown menu.

Step 11. Click the Add button to browse the macOS Big Sur ISO from the File Explorer that you already downloaded.

There are times when you want to use macOS on a Windows computer. For the most part, there was a wall between the two realms, macOS users need to adhere to Apple hardware, and can not be used on a Windows computer, but this wall is slowly disappearing. You can install macOS on your Windows system using a Virtual Machine tool. In this post, we will see how you can install macOS in VirtualBox on Windows 11.

install macOS in VirtualBox on Windows 11

Can I run macOS on Windows 11?

In order to run macOS on Windows 11, we will use Oracle VirtualBox. However, you need to make sure that you have a legally obtained copy of macOS, 2GBs of memory, and a 64-bit computer with 4 logical CPUs, and you should be an administrator or have administrative privileges. If you have all this, go ahead and install macOS on your Windows system.

Installing macOS in VirtualBox on Windows 11 is the following four-step process.

Download macOS File
Install VirtualBox
Create the Virtual Machine
Configure VM’s Settings
Install macOS in VirtualBox

Let us talk about them in detail.

1] Download macOS File

You need to download the macOS file from Apple Store. You need to download the macOS BugSur file from the Store, since it is a large file, you need a good enough Internet connection, an ample amount of space, and some time. Keep in mind, downloading a file from an unauthorized place is not recommended.

2] Install VirtualBox

Once you have downloaded the operating system, go ahead and download VirtualBox, the Virtual Machine software we will be using. To do the same, go to download.virtualbox.org and select VirtualBox-6.1.26-145957-Win.exe. You need to download the extension package called Oracle_VM_VirtualBox_Extension_Pack-6.1.26-145957.vbox-extpack alongside the VirtualBox software.

After downloading both files, go to the Download folder, and run VirtualBox-6.1.26-145957-Win.exe which is the installation package. You then have to follow the on-screen instructions to install the VM, once it is installed, run the extension package and install it as well.

Note: In case, you get an error when installing either of the apps, just disable Memory Integrity, reboot your computer, and then run the installation media.

3] Create the Virtual Machine

In order to install macOS, we first need to create a virtual machine using Oracle VirtualBox. The process may seem a bit intimidating, but if you follow the steps mentioned below, you will be able to create a VM without any hassle. To do the same, just follow the prescribed steps.

Launch Oracle VirtualBox on your Windows system.
Click on the New button.

In the next window, you need to enter the following details.
> Name: You can enter any name you want to give to this virtual machine, but just to have a rememberable name, use a simple name such as macOS or MacintoshMachine.
> Machine Folder: This is the location where your VM will be stored, make sure to select a disk with at least 100GB of free space.
> Type: Select Mac OS X (will be selected automatically)
> Version: Select Mac OS X (64-bit) (will be selected automatically)
On the next window, use the slider to allocate RAM to your VM, give it enough memory but should not be more than 50% of total capacity.
On the Hard disk window, select Create a virtual hard disk now and click Create.

You then have to select the Hard disk file type, we have mentioned their description below, so, select the one you think is apt and then move on.
> VDI (VirtualBox Disk Image): Not for someone who might need to shift their Virtual Machine to some other VM Software such as VMWare Workstation or Hyper-V.
> VHD (Virtual Hard Disk): Apt for transferring the VM to Hyper-V.
> VMDK (Virtual Machine Disk): Best for someone who wants to migrate their VM to VMWare.
Next up, you can select Dynamically allocated if you are not sure how much space is good and Fixed Size if you are certain of the space the VM should be allocated. We recommend you go for dynamic allocation especially if you are using SSD.
In the File Location and Size window, give at least 60GBs and continue.

This way, our Virtual Machine is created.

5] Configure VM’s Settings

Once you have created the Virtual Machine, let us configure its settings to make it suitable for macOS. To do the same, first, we are going to make some changes in the VM that we created and then run some CMD commands, so, follow the prescribed steps to do the former.

Once the VM is created, select it and click on Settings.
Go to System > Motherboard.
Uncheck Floppy, and use the arrow in front of the options to make Optical the first boot option and Hard disk the second.
Go to the Processor tab, allocate at least 2 cores and leave Execution Cap at 100% and Enable PAE/NX. Click Ok to save the settings.
Now, go to Display > Screen, set Video Memory to 128MB, and leave all other settings.

Navigate to Storage, click on Controller: SATA, tick the box next to Use Host I/O Cache, and then select Empty. Click on the DVD icon and then click on Choose a disk file from the menu. Now, go to the location where you have stored the macOS file that you downloaded earlier and select the same.

The job is not done yet, we need to run some commands before installing macOS. Before doing the same, close VirtualBox, not just by clicking on the Cross button but also by opening VirtualBox, right-clicking on the running program, and selecting End Task.

Now, go to gist.github.com and copy all the codes into a Notepad file. In the first line of the copied code, you need to enter the location where you have installed VirtualBox, by default, the location will be the following, but if you have done a custom installation, use a different location.

cd "C:\Program Files\Oracle\VirtualBox\"

After editing the location, change every instance of Your Virtual Machine Name to macOS. After making all the adjustments, the code will look something like the following.

cd "C:\Program Files\Oracle\VirtualBox\"
VBoxManage.exe modifyvm "macOS" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "macOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"
VBoxManage setextradata "macOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "macOS" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"
VBoxManage setextradata "macOS" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
VBoxManage setextradata "macOS" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1

Note: Except for the address in the first line, everything else must be the same in your code as well. However, if you have not changed the location during the installation process of VirtualBox, even the address will be the same.

To run these commands, open Command Prompt as an administrator and execute every single line separately. Running the first line will redirect you to the VirtualBox directory, and the rest of the code is there to make the VM suitable for macOS.

6] Install macOS in VirtualBox

After doing all the aforementioned steps, the environment to install macOS is created, all we have to do now is run the Virtual Machine and install the OS. Follow the prescribed steps to install macOS in VirtualBox.

Open VirtualBox.
Select the macOS VM we created and click on the Start button.
You will be prompted to select the Language, do that and continue.
On the Disk Utility page, click on VBOX HARDDISK MEDIA > Erase.
You will be prompted to confirm your actions, click on Erase when the dialog box appears.
Once it’s done, close the Disk Utility screen.
You will be redirected to the Recovery page where you need to select Install macOS Big Sur and then continue.
Finally, follow the on-screen instructions to complete the installation process.

That’s how you can install a macOS Big Sur on a Windows computer using VirtualBox.
