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 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

Important Note:

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

Note: You can create macOS Big Sur ISO Image.

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

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

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.

    Hey thanks so much for this guide. I tried it on my Ryzen machine (3970x) but I’m getting stuck at the EXITBS:START error like a few people above…I tried the VBoxManage modifyvm “macOS Big Sur” –cpu-profile “Intel Core i7-6700K” command (and did it with virtualbox closed), but it still stops the install…any ideas how to fix? Mobo is a TRX40 Creator, tried this with Hyper-V both on and off, same results…

    Thanks for the help and the guides!

      Definitely not more than 5 minutes on my system. If you are doing this on AMD CPU then: if you have an AMD CPU then Add this code to your VM:

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

        I wait here 15 minutes, i changed ram to 4gb but i can use 5gb processor 2 cores but can use 4 and video memory to 128mb.

  7. blankKen Spreitzer Reply

    Thank you for this! I just used these instructions to install macOS 11.0 Big Sur (beta 4) on a VirtualBox 6.1.12 virtual machine (using my MacBook Pro as a host). Here’s what went wrong and how I fixed it:

    1. You can use any SATA port numbers for your devices, just make sure the .iso file/drive is first. I ended up with BigSur.iso (SATA Port 5), macOS-11-beta.vdi (SATA Port 10), and a DVD (SATA 20) which ultimately ended up having the VBoxGuestAdditions.iso. (After I was all done I used VirtualBox Settings/System to change the boot order to boot from the hard drive before the BigSur.iso.)

    2. The instructions are written for Windows, so you’ll need to run the VBoxManage utility (as shown in the “VirtualBox Code” section) from a different location. So instead of:

    cd “C:\Program Files\Oracle\VirtualBox”

    use this:

    cd /Applications/

    and remove the “.exe” from the first VBoxManage command. So the commands I used were like this:

    cd /Applications/
    VBoxManage modifyvm “macOS-11-beta” –cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff

    3. After starting the virtual machine, I hit a huge problem where it booted into the UEFI “shell” and just left me at a prompt saying “Shell>”. FYI, look at the first lines of this screen and you’ll probably see that “FS0:” is an “alias” to a CD-ROM drive. I found instructions online about typing “fs0:” and then “edit startup.nsh” but this failed with an “Access denied” message because it was trying to edit a file on FS0: (which is a read-only CD-ROM .iso). I also found instructions online about installing an “APFS EIF Boot Image.iso”. But I found an easier workaround. When you get to the UEFI “Shell>” prompt, just type “exit”. (Extra tip: type “help -b” to see available UEFI commands.) Typing “exit” will get you to a BIOS startup screen. Choose “Boot Manager” and it should provide a list of available devices. Choose each of them in order until you find one that works. As I recall, my first device was “EFI (something)” and choosing it didn’t do anything. My second device was a SATA device (as I recall), and it was mapped to the BigSur.iso install image that I was trying to install; choosing it worked!

    4. Once I managed to choose the correct boot device image as discussed above, it started to install. You’ll see a ton of text scroll by. Just let it work.

    5. The entire installation process will need to reboot a bunch of times (5?), even after you’ve done the main 29-minute installation part.

    6. At one point I thought the installation was frozen because it was stuck on a line that read:

    Forcing CS_RUNTIME for entitlement

    It seemed to be stuck on this FOREVER, but it finally continued after about 30-45 minutes.

    7. When doing the initial Apple ID and iCloud setup, it got the error “ICLOUD_UNSUPPORTED_DEVICE”. I gave up on signing into iCloud for the time being. (I’ll try to figure it out later.)

    8. The machine seemed to not recognize the host MacBook Pro’s keyboard. It had me press Z and / to determine that it was a US ASCII keyboard.

    9. I couldn’t get the VirtualBox Guest Additions to install. The installer package seemed to run OK but at the end it gave an error message. The largest effect of this is that VirtualBox can’t capture the keyboard, so when I press Command-Q (for example) it gets passed through to the host. Also, the trackpad doesn’t seem to scroll; I assume it’s the same problem due to the missing Guest Additions.

    10. Since I didn’t want to update my MacBook to the Big Sur beta, I removed the “profile” described near the start of this article. To do so, go into System Preferences / Software Update. On the left side, underneath the gear, you’ll see a message that your computer is enrolled in the beta seed program. Click the link to get a little window which will let you confirm that you want to remove that profile and revert to your existing (non-beta) config.

    BTW, I created a 100GB hard drive (in VirtualBox), and there were 87GB free after I finished installing Big Sur, so macOS 11 took about 13GB to install.

    I hope this helps someone!

    Hi ! Thanks a lot for this pretty useful guide, which helped me to install Big Sur on VirtualBox on Windows 10 (rel 1909). I’m however facing two issues, whose resolution got me into some trouble and i’m seeking advice to get back to a workable situation.

    1) Belgian French Keyboard is not recognized by Big Sur, which made me provide all setup inputs with a wrong keyboard, but I somehow got through it I guess.
    – I’m using in the meantime a French keyboard layout but all keys don’t match, sadly :'(
    – I hoped that adding the Guest Additions (Darwin) could help, but when I tried to install the dpkg file it failed at the end and I’m not even sure it caused a trouble or not :-O
    – When looking into the System Info I checked for Updates of Big Sur and see there is one pending… which I’m downloading now — hopefully the belgian keyboard has been added ?

    2) The actual performance is really poor in my opinion. The mouse pointer is stuttering all the time when moved and starting an application takes several seconds (3-10). So I’ve looked into that and I’m doing the following:
    – upgraded VM RAM from 4 GB to 8 GB, but kept the 2 processors only (my i5-4690system has only 4, but they are actual cores, and my PC is otherwise very smooth in games, other VM’s and anything)
    – I admit I selected as disk (70GB) the VDI type instead of VHD and it is of dynamic type… my bad. Q1: Firstly, there seem no option or process to convert a dynamic to fixed length format, supposedly faster ? Any hint or tip here ? Secondly, when I used VBox’s media manager to copy the VDI to VHD format, MacOS would not boot anymore : the VM would immediately display a screen full of status info with hex code and status values all over the place a stop with a “Shell >” prompt. When typing Exit, I’m entering a boot manager setup displaying 4 entries, none of which are working when leaving the boot manager (I’m back to the Shell prompt each time). Any pointers to what might be the issue here ? I still have the VHD disk (though I have reconnected to the VDI now, which is pretty slow but works at least)

    Thanks in advance for your advice !

    PS: I’ve read you’re recommending VMware instead of VBox but I’d really like to push it to the maximum of tuning before adding one more virtualisation software and having to learn its specificities.

    1. blankArnold Schwarzie Reply

      I’ve tried to install it right away to a VHD of fixed size but it fails the same way : it cannot start after installation and I’m left with a Shell prompt without knowing what is wrong or what to do next.
      When ‘exiting’ I’m reverted to the Boot manager with much more clues…
      Please help ?
      PS: see attached screenshot

      What is your system specs? if you have an AMD CPU then 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.

      If no then try the Fix the Operation Couldn’t be Completed BiErrorDomain Error 3 article.

      If no success then I highly recommend you to Install macOS Big Sur on VMware on Windows 10 because it works much better than VirtualBox.

      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. blankFaiz

        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.

    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:

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

      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.

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

        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.

        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.

        It’s working 100% now, see:

        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


        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.
