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

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.

    Well I Ran The codes through the windows command prompt (ADMIN MODE) and when i run the codes 1 by 1 through the command prompt i think something is wrong because when i started the VM it rebooted and did a kernal panic I Saw this message in the codes that i knew it was a kernal panic

    THE SYSTEM REBOOTED AFTER PANIC

    Isnt there a way to fix this

    1. blankFy Reply

      I had the same problem too. Left it like that for about 4 hours and finally sprang to life. It seriously tests your patience. For checking whether the installation is going well, go to libraries and click on my computer. you will see that the space in C drive will gradually decrease this indicates that your the installation is still in process.
      Just wait.

    Can you please help?

    Hi,
    Thank you for this excellent guide!
    I have however the following problems:

    – SLOW: Big Sur runs incredibly slowly. 20 minutes to boot and 30-60 seconds to open Safari for instance. The installation itself took several hours.
    I dedicated 16GB of memory (my windows 10 host has 64gb). My system is a dual CPU Xeon E5 32-core machine.
    Reading Jordan’s recommendation above I checked and hyper-V is disabled on my machine. DeviceGuard and Core Isolation Details (Windows Defender) were also turned off.

    – Unable to use more than 2 cores. I tried defining 4 or 8 cores and the system will not boot. It will only boot when I define 2 cores.

    Thanks for the manual, everything was installed and working. I also managed to change the screen resolution to the one I needed.
    The only thing is that the system is working very slowly, although I allocated 10GB of RAM and SSD of physical memory to it. Can you tell me how you can solve this problem.

    Hi, when I try to access my iCloud account it makes me mistake .. so I ask, within virtualization: is it possible to enter my Icloud account so as to use the services and synchronize my Apple data, as if I had an original Mac? For example the use of apps such as Photos, Notes, Mail, Calendar..ect.

    Also, despite a PC with i7-6700 2.60GHz with 16RAM and still 50GB free, using BigSur turned out to be very slow up to having simple mouse pointer delay, what could it be?

    So I have been trying to install this for 5 days now with no success. I am trying to do in on a Dell XPS 9560 (i7-7700HQ, GTX 1050 4GB, 16GB RAM, 512GB NVMe SSD). Could it be because my VirtualBox is set to run with the nVidia GPU instead of the integrated one (Did that as a fix to the Ubuntu VM visual stuttering problem)?

    For additional info: I am trying to install with the latest BigSur from the link at the top of the post.

    I did everything you explained. But, when I started booting VM, it was stuck at #[EBILOG:EXITBS:START] (current date). What should I do?

  23. blankalpine Reply

    For those of you getting the error “LOG:EXITBS:START”, you need to be using the latest version of VirtualBox with the extensions. If you’re using Virtualbox <6.1, it wont launch.

      I have latest VirtualBox (6.1.16 r140961) and got the Extensions install today, so also newest. I did the –cpu-profile “Intel Core i7-6700K” as well, and still cannot get it to boot on my AMD Ryzen 5 3600XT PC.

    Hi Mukhtar,

    Thanks for the nicely constructed instructions. Awesome work mate!

    For you and anyone else interested in trying this procedure with Linux/Ubuntu, here’s what I did, and after a bit of stuffing around, found a process that works, as follows.

    I used your exact process with Big Sur as a VirtualBox Client, but instead, used Ubuntu 20.4 LTS as the VirtualBox Host.

    I created the Big Sur VM client on an external USB3.0 drive.

    I also stored the Big Sur macOS ISO file on the same external USB3.0 drive in a separate folder.

    I named my Big Sur VM image: macOS Big Sur-20201217

    I followed your procedure quite closely except used the following linux commands in an ubuntu Terminal window:

    —–
    $ cd /bin

    $ VBoxManage modifyvm “macOS Big Sur-20201217” –cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff

    $ VBoxManage setextradata “VM Name” “VBoxInternal/Devices/efi/0/Config/DmiSystemProduct” “iMac19,1″^C

    $ VBoxManage setextradata “macOS Big Sur-20201217” “VBoxInternal/Devices/efi/0/Config/DmiSystemProduct” “iMac19,1”

    $ VBoxManage setextradata “macOS Big Sur-20201217” “VBoxInternal/Devices/efi/0/Config/DmiSystemVersion” “1.0”

    $ VBoxManage setextradata “macOS Big Sur-20201217” “VBoxInternal/Devices/efi/0/Config/DmiBoardProduct” “Mac-AA95B1DDAB278B95”

    $ VBoxManage setextradata “macOS Big Sur-20201217” “VBoxInternal/Devices/smc/0/Config/DeviceKey” “ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc”

    $ VBoxManage setextradata “macOS Big Sur-20201217” “VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC” 1
    —–

    Then I created a snapshot of the VM using VirtualBox so that I can revert back to this snapshot if needed.

    Then I performed the disk erase process you explained, and named the virtual disk which was 128GB in size as: macOS HDD

    I also used a ‘MacOS Extended (Journaled) with case-sensitivity’ option for the erase process, and used the scheme: GUID Partition Map. Now, I’m not sure if selecting the case-sensitive alternative will be an issue down the track, but it’s a VM so I can always revert to a snapshot and try it again without case-sensitivity later if there are problems with this for the OS.

    Then when I installed the OS, the installer just hung after about 60 seconds. Well damn, that’s linux. Upon inspecting the error logs these said something about an (… isCSFusionDrive:] failed to get LVG for diskls3) and (… invalid LVGUID) and would not proceed with the install. I googled the error and could not find anything specifically useful on this error message to resolve the hang.

    So, I then erased the virtual disk again with the exactly the same process above, but then used the same disk management tool to perform a partition of the virtual disk volume. So what this means is that I split the original 128GB volume into 2 equal volumes of 64GB each. I named the second volume partition: macOS HDD2

    Now I effectively have 2 hard disks of 64GB each: macOS HDD, and, macOS HDD2.

    Then I exited the erase tool and ran the ‘Install macOS’ process as you described, then selected the 64GB disk volume named ‘macOS HDD’, continue, and you bloody ripper, it proceeded with the install just fine, but took about 45 minutes to complete. My external drive is an older spinning disk, not an SSD, so it’s very slow, but it means I can watch/read the Apple scripts used to install macOS which is super interesting.

    I’ve no idea why this split volume technique solved the logical volume GUID issue I hit originally, but this split volume process worked.

    I figure that I can go back and resize the macOS HDD volume back to 128GB later and blow away the macOS HDD2 volume in the process.

    I hope this helps others trying to do the same with Linux/Ubuntu as a host and installing on an external USB3.0 disk.

    Cheers,

    How to get passed “ICLOUD_UNSUPPORTED_DEVICE”??

    Thanks. Following these instructions worked perfectly for me. However, previous MacOS installs on Virtualbox have always allowed me to log in to the Apple store. It’s the primary purpose for me to have MacOS on VM. Is there any way to get past the “ICLOUD_UNSUPPORTED_DEVICE” error when attempting to login into the Apple store? This error was also reported in a couple of other comments. This error will constantly block access to Apple Store and has been accessible via previous MacOS versions installed via Virtualbox. I realize the VM is not authentic Mac OS and/or Mac OS hardware. But this has worked in the past. I am only looking for a solution.

    Hello, I’m having an issue, and I’m not sure if I should just keep waiting or if there’s something wrong. I followed the guide to the letter, and also did that extra CPU ID code to get where I am. I tried adding the screen fixed resolution code and that didn’t do anything. Currently, I have 2 cores assigned to the VM as I have 4 cores in total, and 4 GB of RAM as I have 11.2 GB usable. My CPU is AMD A10-5750M APU with Radeon(tm) HD Graphics.

    Here’s the link to my VM: https://imgur.com/a/zdv0hlf

    Despite it not seeming to be doing anything, the VM’s currently using 27-38% of my CPU, but I’ve waited almost 20 minutes now for it to do anything, as I write this it’s still in the background doing.. nothing.

    Any help would be much appreciated! Oh, I’m also trying to install Big Sur 11.0.1

    My own experience, using macOS Big Sur 11.0.1 (20B29).iso, on a Linux Mint machine, running 19.3 Mate, on an older Dell XPS with an intel i7 and 24gigs total memory.

    Basically, everything is the same as it is with Windows, and the instructions are sterling, all the way through. One difference with Linux is that you open a terminal instead of a command prompt, and with VirtualBox already installed, simply typing in “VBoxManage” followed by whatever instruction(s) might be at hand on the very same input line and then hitting the ‘Enter’ key, works in exactly the same way. So that’s easy enough to deal with.

    In the beginning, things went really fast, and that kind of mislead me, and later on, when things slowed waaaaay down, it caused me to make a couple of mistakes, so give it time, ok? Be patient with it.

    My first stumbling block occurred when it was time to erase the “installation disk” with the Disk Utility, and almost immediately VirtualBox threw an error and the process froze up. Not knowing what the fuck to do, I did the wrong thing.

    Of course.

    I tried to figure out the freeze-up, but could not, and said “The hell with it,” to myself, and WIPED IT CLEAN.

    Fresh start. From dead scratch, creating an new VM.

    When I got to the “erase” point once again, if promptly locked back up, once again, same place. Prior to that, I noticed that it defaulted to a Format of APFS file system, with a GUID Partition Map Scheme instead of Format as Mac OS Extended (Journaled), which is what’s showing in the screenshot above, in the instructions, and I decided to leave that alone, but it froze anyway, and I was right back where I started, and this time, putzing around with things, I just kind of happened to notice that the machine state, in the VirtualBox Manager, was showing as “Pause” so I clicked that button, and low and behold, it lit right up, and kept on stroking, from there, as if nothing had ever happened.

    For a looooong time. And there was a lot of stuff, but it all went well enough without any alterations from my obedient little self, so we’re not gonna talk about it. Except for additional lockups with a VirtualBox Manager showing “Pause” so if you get any of that crap, be sure and give that one a look, ok?

    And when it got to where the Apple logo showed up, but before a cursor arrow could appear against the blackness of the install background, and the little bar was creeping along, I noticed that the damn bar only made it about a quarter of the way across, where it steadfastly refused to move from, even as the timer kept counting down, to “less than a minute” and from there….. nothing. I let it sit for fifteen minutes or so, and foolishly decided it was frozen, and killed the Virtual Machine without saving the state.

    Started it back up, and as a reward for being stupid, I got to once again watch the bar, and the countdown timer, do the exact same thing again, but this time I left it strictly alone, over there on my second monitor, and busied myself with other pursuits, and after a pretty good while, it suddenly lurched back into life, and proceeded to throw lots of white gobbledygook across the black background, gave me another status bar (which thankfully did not last as long), went back to gobbledygood, and the goddamned thing TOOK FOREVER. During which forever it would occasionally “hang” for interminable lengths of time, but finally it kicked all the way through.

    And a few more “Pause” events along the way, but it never stopped the process.

    And now it’s working, and I could not be happier.

    Altering the screen resolution was another weird item too, though, and I had to do a LOT of playing around with that, and for some reason, it would refuse to take a given resolution, boot into the default low resolution, and this annoyed me greatly, until, for reasons I do not know myself, i decided to slide the damn thing from one monitor to another (they’re different sizes, different resolutions), and in the process of sliding across, the VM jerked into the proper resolution, and I’m gonna leave it right where it is, lest I fuck it up further, by trying too hard with it.

    Gonna let it rest. It’s earned it, right?

    Most of a day, spent.

    Every minute of which was worth it.

        Not a problem. Just be patient. As far as I can tell (based on gkrellm showing my actual disk activity), it counts down while *just* reading the installer (probably doing a checksum on it), then does the ENTIRE install claiming “less than a minute remaining.” I quit waiting for it after like 20-30 minutes, checked quite a while later and it was done.

    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/VirtualBox.app/Contents/MacOS

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

    cd /Applications/VirtualBox.app/Contents/MacOS
    VBoxManage modifyvm “macOS-11-beta” –cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
    (etc)

    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 com.apple.rootless.restricted-block-devices

    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.

      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 ?

        I used your file. Did even the download twice in case it got corrupted but did a file compare by content and it was ok.

    Thx for writing this article.
    I actually get a problem that I did successfully installed the macOS Big Sur into Virtual Box, but after I created the Account and trying to login, the screen turns black for a while and then skip back to the login menu again. Is there any idea about this problem?
    I’m pretty sure that I had followed every steps being mentioned in the article. Also I’m using the latest version VirtualBox and the iso file in this post.

      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.

    Hi, im having issues downloading the MacOS Big Sur beta ISO, when it finish downloading it give an error saying the file is damaged, i tired downloading again but it keeps giving me the same error every time.

    if could help me out.

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

  55. blankKai 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. blankFaiz 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. 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.

      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.

    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

    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. blankJordan 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.

  60. blankJordan 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.

      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. blankJordan 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. blankMukhtar 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. blankJordan 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.
