How to Install macOS Big Sur on VirtualBox on Windows – PC

Apple has announced the next major release of macOS at WWDC 2020. Available today in developer beta and coming to all users in fall 2020. macOS Big Sur will be a free software update later this year. In the meantime, the developer beta is available on https://developer.apple.com/macos/ and for public beta in July.

This OS has new features that include an all-new iOS inspired design, Control Center arriving for Mac, a revamped Safari with greater privacy controls, Apple’s new translation software that uses on-device processing, and more.

Macs compatible with macOS Big Sur (macOS 11):

  • 2015 and later MacBook
  • 2013 and later MacBook Air
  • Late 2013 and later MacBook Pro
  • 2014 and later iMac
  • 2017 and later iMac Pro
  • 2014 and later Mac mini
  • 2013 and later Mac Pro

And Accordingly, the following models capable of running macOS Catalina will not be able to be upgraded to macOS Big Sur:

  • 2012 and Early 2013 MacBook Pro
  • 2012 MacBook Air
  • 2012 and 2013 iMac
  • 2012 Mac mini

Tip: before reading the rest of the article, it’s recommended to navigate to the Required File section of this post and download macOS Big Sur then you’ve time to read the item until the downloading gets complete.

Steps to Install macOS Big Sur on VirtualBox on Windows

  • Install VirtualBox on Windows PC
  • Install/Update VirtualBox Extension
  • Create a New Virtual Machine & Customize it
  • Run VirtualBox Code to the Command Prompt
  • Start the Virtual Machine
  • Perform Clean Installation of macOS Big Sur
  • Summary

Before we get started, make sure your system can support Virtualization Technology (VT), and it is enabled from BIOS so that you should be able to run Virtualization software like Virtualbox or VMware. Also, you should have a 64-bit Windows operating system with at least 2 GB Ram and 20 GB of free storage, however, we recommend you at least 4 GB of RAM or higher so you can store more files and install more apps on macOS Big Sur.

Furthermore, if you have an SSD, it’s highly recommended to use it as storage because SSD is much faster then mechanical hard drive (HDD ) and macOS run on SSD very smooth. Anyway, it is not 100% compulsory but if you have, don’t hesitate to use it.

Required Files

Recommendation: It’s highly recommended to create a new drive on your Windows PC and install macOS Big Sur on that drive.

Step 1: Install VirtualBox on Windows PC

From the “Required File” section of this post, you should have downloaded VirtualBox as well and if you didn’t, download VirtualBox’s latest version and install it on your Windows system. If you’ve already installed VirtualBox, then you can skip this step. Other than that, double click on VirtualBox Setup and click Next for a couple of times and you’re done with the installation.

Step 2: Install or Update VirtualBox Extension

This step is not 100% percent necessary but it’s highly recommended to do this step because macOS Big Sur might not be compatible with VirtualBox and for this reason, it will cause a problem during the installation. Download VirtualBox Extension and follow the steps below.

#1. Open up VirtualBox, navigate to Tools>Pereferences>Extensions.3

#2. Click on Plus icon and select VirtualBox extension which you’ve downloaded at the beginning of this section. Click Install or Upgrade and then click OK button.

#3. Finally, you should see something like the screenshot below.

Update Virtualbox Extension

Step 3: Create a New Virtual Machine & Customize it

Creating a virtual machine for macOS Big Sur is the same when you create a virtual machine for the Windows Operating system or Linux. We will use the ISO image of macOS Big Sur to do the installation process.

Note: We’ll make the VMDK as well if we receive lots of requests for that. Otherwise, there is no point because you can install macOS Big Sur with iso image as well.

#1. Open up your VirtualBox application and click New.

#2. Type a name for your Virtual Machine. Click Expert Mode and choose the following options then click Create.

How to Install macOS Big Sur on VirtualBox on Windows - PC

Expert Mode

  • Name the VM
  • Virtual Machine Location (a separate drive is recommended)
  • Type (Mac OS X)
  • Version (Mac OS X 64-bit)
  • Memory 4 GB (recommended 8 GB or higher)
  • Create a virtual hard disk 
Your setting should look something like the screenshot below.

Create New Virtual Machine

#3. Select where you want to save your virtual hard disk. Also, make sure to increase the size of the disk. From virtual hard disk, type make sure to select VHD. If you select dynamic allocated, your VM speed will not be good but it’s good that does not allocate the specified storage at once, unlike fixed-size type.

Create Virtual Hard Disk

#3. It’s time to customize some of the settings according to your choice. Click Settings and from the pane choose System. On the Motherboard, tab uncheck Floppy disk and move it down. If you’re not happy with your memory setting still, you can change it.
#4. Click the Processor tab and select a minimum of two processors or higher.

Increase the Processor

#5. Navigate to the Display menu then increase the Video memory to 128 MB.
How to Install macOS Big Sur on VirtualBox on Windows - PC

Increase Video Memory

It’s time to select your macOS Big Sur ISO file. Click Storage and then select on Empty. Click on DVD icon and choose your macOS Big Sur ISO file.

Select ISO Image

Make sure your macOS Big Sur ISO file is on the top, not your Disk because if your disk is on the top, your VM might not boot. Just change the SATA port number to 0 for your iso image. It’s not 100% compulsory.

ISO Image SATA 0

Step 4: Run VirtualBox Code to the Command Prompt

Once you’ve created and customized your virtual machine, it’s time to run some codes in order to install macOS Big Sur on VirtualBox.

First, you should notice your virtual machine name because later on, we will use it. Open the VirtualBox code which you should have downloaded from the Required File section of this post.

#1. When you opened VirtualBox code via notepad or any other text editor, use the replace function of the program to replace the VM Name to your virtual machine name. See the picture below to get an idea of how it’s done.

cd "C:\Program Files\Oracle\VirtualBox\"
VBoxManage.exe modifyvm "VM Name" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac19,1"
VBoxManage setextradata "VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "VM Name" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-AA95B1DDAB278B95"
VBoxManage setextradata "VM Name" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
VBoxManage setextradata "VM Name" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1

Replace VM Name

Tip: It’s highly important that you should quit the VirtualBox program before executing the code. If you don’t do it, your virtual machine might not proceed to the installation step.

Exit VirtualBox

#2. Once you replaced the “VM Name” with your virtual machine name, then run the code one by one to the command prompt (CMD). You can open the command prompt by pressing Windows+X key in Windows 10 or click windows key and type CMD and run command prompt as administrator.

Step 5: Start the Virtual Machine

Starting macOS Big Sur with the older version of the Mac Operating system was a bit different, but with new macOS Big Sur still, it’s easy to set it up.

#1. Open the VirtualBox app then click the Start button. A black screen with a few yellow & white text will appear on the screen.

      Hi, I am not sure but to double-check, Is your Virtualbox the latest version (6.1.10)? Have your installed the VirtualBox Extension?

  1. Kai N. Reply

    Hi guys. Doesn’t work for me because i’ll always get an error “VBoxMana.exe: error: Could not find a registered machine name ‘Mac OS Big Sur’. I found out that my machine is in a different folder. It’s in my user folder. What to do right now?

    1. Faiz Reply

      When you opened VirtualBox code via notepad or any other text editor, use the replace function of the program to replace the VM Name to your virtual machine name (this should be exact).

      Also, make sure to use CMD (As admin) not Powershell.

      1. Faiz

        Did you CD to “Program Files\Oracle\VirtualBox\”?

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

        If you have installed Virtualbox in another folder then you may have to cd to that folder.

        Add this code to your VM:

        cd "C:\Program Files\Oracle\VirtualBox\"
        VBoxManage modifyvm "your VM name" --cpu-profile "Intel Core i7-6700K"

        P.S It’s highly important that you should quit the VirtualBox program before executing the code.

      Hi, I have the same error. After installing macOS and partitioning the drive on the recovery screen successfully, and then waiting 29 minutes on the apple logo code scrolls on the screen and seems to get stuck on:
      CS_RUNTIME for entitlement: com.apple.rootless.restricted-block-devices

      I followed the steps exactly and it was working up until there, does anyone have any suggestions? I already tried deleting and re-doing the VM and it is still the same.

      There are other ways that can help the original creator to protect their works without a lawsuit. A lawsuit can be the last option as it might be an expensive and long process to go. I encourage you to read this article on how we can protect our content online.

    is there any way i can fix the screens ratio, it stays at a 4:3 ratio and i cant change it to my monitors ratio, so it has 2 giant black bars on both sides

  5. Gustavo Vilas Boas Reply

    I managed to get through the installation steps, but when the system boots, it gets stuck at this “Forcing CS_RUNTIME for entitlement: com.apple.rootless.restricted-block-devices” message. Tried searching for it but couldnt find anything related to restricted-block-devices.

      Actually I just had to wait like 5 hours and then It worked. It is very laggy but Its usable. Thanks for the tutorial!

      1. Jordan van Bergen

        Do you have the May 2004 version update of Windows 10?
        If yes read my comment on how to fix the laggy issue with this version. It will be fast as normal again.

  6. Jordan van Bergen Reply

    After getting it to work with VMWare I tried booting my Catalina version on Virtualbox but this really doesn’t start at all and is very slow as well.

    I have the Windows10 May Update:

    Windows 10 – Version 2004 OS Build 19041.329

    So it could well be that everything depending on virtualbox doesn’t work as it should due to the Windows 10 may update. BlueStacks Android emulator doesn’t work any longer as well due to the May Update.

    So I found this as well: https://dev.to/bobnadler/virtualbox-6-1-x-windows-10-2004-upgrade-problem-resolution-4i39

    So a lot is not functioning 100% after Windows 10 – Version 2004 OS Build 19041.329 with virtualbox.

    1. Mukhtar Jafari Post author Reply

      If you’ve followed our guide thoroughly, we’ve said the virtualbox doesn’t completely support the new macOS Big Sur at this time but we’ll update the post once everything works fine.
      Also, if you really need to up and running macOS Big Sur, we recommend you to use our Install macOS Big Sur on VMware guide because it’s working.

      1. Jordan van Bergen

        Okay….. I do get this now after long waiting:

        https://i.imgur.com/yyNtxjS.png

        But I don’t go passed the Disk Utility screen. Mouse is really not responding and screen is very slow with Virtualbox.

        So I got somewhat further but this takes too long.

        I don’t like VMware as i always get the 64bit remark that the hosts needs to be 64bit as well otherwise you can’t run a 64 bit virtual machine. But of course my host is 64bit and I set all settings correctly. It’s an i9 processor that won’t work together with VMware for now. I tried everything. That’s why I am sticking to virtualbox as this is working nicely on windows and with catalina for example.

      2. Mukhtar Jafari Post author

        You’re totally right but at this point, we also looking for a better solution to get passed from selecting the disk. When you select the disk then you can’t actually select it because it won’t let us do that unless we change some code in the configuration file of the virtual machine. It’s quite challenging but we’re working on it to find a solution. We’ll update our guide as soon as we come up with a good solution.
        Btw VMware is working for us very well but I’m not sure why it’s not working for you?
        I’m using VMware 15.5. You can download VMware latest version from this website but the language is Persian. If you don’t trust them then you can download from its official website.

      3. Jordan van Bergen

        It’s working 100% now, see: https://i.imgur.com/e3zf5yV.png

        I had to do this: It’s due to the Windows 10 Version 2004 May Update !

        If you do the following if you have the same issues than it will work again:

        1. Control panel -> Programs and Features -> Turn Windows Features on or off -> Uncheck Hyper-V and Windows Hyper-Visor Platform

        Additional Notes for Windows Hosts

        2. To check the status of Hyper-v in Windows 10, | Run | OptionalFeatures.exe, and look for the “Hyper-V” option. The box should be empty, not checked or shaded. If you want to be absolutely sure that Hyper-v is gone then open an administrator command console and type “bcdedit /set hypervisorlaunchtype off”. Make sure to fully power down and reboot the host after changing the Hyper-v setting.

        3. On some Windows hosts with an EFI BIOS, DeviceGuard or CredentialGuard may be active by default, and interferes with OS level virtualization apps in the same way that Hyper-v does. These features need to be disabled. On Pro versions of Windows you can do this using gpedit.msc (set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security to Disabled. CredentialGuard is a subset of DeviceGuard, so disabling the former should be enough. If you cannot use gpedit for some reason then the equivalent registry hack is to find the key

        HKLM|SYSTEM|CurrentControlSet|Control|DeviceGuard|EnableVirtualizationBasedSecurity|Enabled

        and set it to 0.

        4. On Win10 hosts, check Windows Defender > Device Security > Core Isolation Details and make sure settings in this panel are turned off, reboot the host from power down if you needed to make changes. “Core isolation [includes] security features available on your device that use virtualization-based security” …which is why they can interfere with VirtualBox.

        Thanks for you time for submitting this solution. We really appreciate your time Jordan.
        Also, you’ll be able to fix the slow performance of macOS Big Sur or any other version of macOS by giving it more RAM, and Processor and it’ll perform much better.
