You can run MacOS in Virtualbox. Because? Because.
In the pursuit of Hackintosh, you need a Mac. That’s well and great, but I didn’t want to screw around with my partner’s Macbook. So what if you want to sandbox something? Virtualbox!
I had no expectations that this was going to work. OS X has always been runnable in Virtualbox for a while, but the performance has normally been lacklustre. While it’s not exactly daily-driver level, the performance in Virtualbox wasn’t too bad!
The macOS Virtualbox option is designed for genuine Apple hardware. You will not get community support from Virtualbox if you have trouble with this process, as it’s against Apple ToS.
Note that if one day you'd want to change your Mac's operating system to Windows or Linux then you'd might want to install one of the other mentioned VM managers since those can run on those host OSs albeit with a much more involved setup. We will also be using macOS High Sierra as the installed OS. You can use these instructions for older. If you're on Windows, need to use OS X, but don't want to buy or build a new computer, reader Bobby Patton shows us how to run Snow Leopard in a virtual machine on Windows with just a few tweaks. Host OS: MacOS 10.14.3 Mojave Virtual Box 6.0.4 Guest OS Linux Mint Mate 19 1 I am getting very slow performance on this guest, when moving windows it stutters. When playing short MP4 videos in VLC, the app goes non-responsive and is incredibly slow to respond to input. The relevant VM settings are:-Video RAM: 128Mg Base Memory: 2048 Mb CPU: 2.
?️ What do I need?
You need a donor Mac to start this process. You will not need access to it permanently, but just during the process of creating an ISO for your VM to setup with. Else, you need:
- A Mac to create an ISO with.
- MacOS Mojave installer from the Mac App Store.
- Virtualbox (Windows, Linux or MacOS).
- Virtualbox Extension Pack is required.
- At least 4GB of RAM (8GB or more recommended).
- 40GB of free disk space (more preferred).
- 2 core CPU or more.
This guide will discuss installing MacOS Mojave, however installation process should be similar for all MacOS versions.
⚠️ At the time of writing, Virtualbox and Hyper-V cannot co-exist on Windows. MacOS is also not installable on Hyper-V. I use Linux in my screenshots as I use Docker on Windows. This also includes Windows Subsystem for Linux, which tripped me up from installing.
?️ Creating the ISO
Virtualbox installs generally prefer to use an ISO file, which unfortunately will require some handiwork to get a hold of. Persevere and you will get there!
On the MacOS machine, download the Mojave installer. Don’t worry about actually running this application, as we’re going to use some terminal magic to build the ISO from the package.
This process is not affected by MacOS Installer expiry.If your MacOS installer has expired, you can continue with this guide.
Once the package has been downloaded, pop open Terminal (Utilities folder in Launcher), and run the following commands:
hdiutil create -o /tmp/Mojave.cdr -size 8000m -layout SPUD -fs JHFS+
This will create a virtual ‘disc’ stored in your temporary directory. This is what we’ll stuff the Mojave installation stuff into.
hdiutil attach /tmp/Mojave.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/installer_goes_here
Now MacOS can ‘see’ your disc as an actual disc, ready for writing to!
asr restore -source /Applications/Install macOS Mojave.app/Contents/SharedSupport/BaseSystem.dmg -target /Volumes/installer_goes_here -noprompt -noverify -erase
We’re now grabbing the installation DMG from within the updater package, and storing it within the disc image. This will rename the disc image, so don’t panic that ‘installer_goes_here’ has vanished.
Now, detach the image from our MacOS. You can just eject it like regular DMGs. If not, run the command:
hdiutil detach /Volumes/OS X Base System
(it may change since OS X is legacy. To check, run
ls /Volumes
and see if it’s there, renamed).Now for the final process, let’s convert our CDR image to an ISO!
hdiutil convert /tmp/Mojave.cdr.dmg -format UDTO -o ~/Desktop/Mojave.iso
You should now have a file on the Mac desktop called ‘Mojave.iso’. Congratulations, you have your installation disc! Copy this over to where your Virtualbox is setup. The Mac is no longer needed at this point.
?️ Setting up Virtualbox
⚠️ Before continuing, install the Virtualbox Extension Pack, if you haven’t already. This comes with a special USB 3 driver that without, the Mac simply won’t see USB devices.
Virtualbox has the option for a MacOS virtual machine in it’s New VM dialog, but we will need to make further adjustments to make it truly Mac-ready.
Pop open Virtualbox, and Create a new Virtual Machine. Name this MacOS Mojave, and set it to Mac OS X (64-bit).
Set the RAM to 4096 MB (or higher if you can achieve it!).
When creating the disk, you can use either format versions. Dynamic will not immediately take up the storage size you chose, whereas Static immediately reserves the chosen size for the VM. The latter is slightly better for performance.
Now you should have a new, primed MacOS machine. But you will need to run some commands now. This can be hit-and-miss, and may require some Google-fu. The following works for my AMD FX computer:
Windows? Change
VBoxManage
to 'C:Program FilesOracleVirtualBoxVBoxManage.exe'
(if you didn’t change your Virtualbox install location).The above does the following, in order of command:
- Sets a known CPU ID set that MacOS will recognise.
- Especially for AMD machines, changes what MacOS sees as your processor to something it supports.
- Tells MacOS you’re installing Mojave onto a mid-2010 iMac. You can change this to your preference.
- These two specify a fake DMI, typically found in Apple PCs.
- A device key to pass system checks.
Before starting the VM, open the VM settings and make the following changes:
- System > Processor > Processor(s) is 2 or more.
- System > Acceleration > uncheck Enable Nested Paging.
- Display > Screen > Video Memory is 128MB.
- USB > USB 3.0 Controller.
- If greyed/not there, you did not install additions.
With all that done, we’re ready to start the VM!
You should be greeted with the following screen:
Click on the folder icon, and find your ISO created on the Mac before, then click Start.
And wait. yes, this process takes a long time. If your installation stops, try googling the last output message to see if there is a community fix, or post below… Otherwise, this is generally a slow process.
If all has gone well, you should be greeted by the MacOS installer language selection. If so, you’re almost there! On the top menu, open Utilities > Disk Utility.
There should be a disk named VBOX HARDDISK or similar. This is the VDI you created during the setup process, and not your actual hard drive. So go ahead and full-erase this disk, with Mac OS Extended (Journaled) and GUID Partition Map.
Once the disk formatting has completed, close it down. You should now be able to start the installation!
Once this is complete and you filled all the required details in, congratulations! You’re running MacOS Mojave within Virtualbox!
?️ What works?
✔️ Does
- Screen (No 3D).
- Regular input methods (mouse sharing).
- Networking.
- USB devices.
- Mac App Store.
At the end of the day it’s still a virtual machine, and a technically unsupported one at that. However, considering the matter it’s still impressive how Virtualbox can cope with MacOS.
Files can be shared using typical Windows share features. If you share a folder on your network from your host machine, your Mac VM should be able to connect to it.
?️ Special Thanks
This required a lot of Googling, and these are the people who saved me at the end of the process!
- This How-to Geek article, that started this whole process. They have a much better step-by-step guide on this!
- Forchia on Reddit for a different instruction set.
- miranhasan on Reddit for AMD processors.
- kvotheV on Reddit for disabling nested paging.
? Troubleshooting
This is a difficult one, and will require investigation. I checked the logs as the error message said, and discovered:
HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available
If you’re on an Intel processor, it’ll likely say VT-x instead.Obviously, check if this is enabled. If you’re on a legacy BIOS computer, it’s a straightfoward scan for AMD-V/VT-x in your settings. If it’s UEFI, you’re gonna have to Google it.
Strangely, on my machine it was enabled. Supposedly Virtualbox and Hyper-V can run side-by-side, so at this point I decided to remove Hyper-V, to see if that would improve. It didn’t, but I forgot something. For this to work, you must turn off Windows Subsystem for Linux!
I completely forgot that WSL uses Hyper-V, and apparently still does when it’s disabled. Unfortunately, it would seem (for me at least) you need to trade it off for macOS in Virtualbox.
I will retest this when WSL2 is launched.

Mac OS is a computer operating system developed by Apple. This is a operating system with beautiful interface, however, to own a the computer of Apple with this operating system, you need to use a lot of money, normally with the double price than that of common computers using Windows operating system. Fortunately, you can experience the Mac OS right on your computer by installing a Mac OS virtual machine on VirtualBox.
Below is the list of Mac OS versions released in recent years:
Mac OS Version | Name | Release Date |
10.10 | Yosemite | June 2014 |
10.11 | El Capitan | September 30, 2015 |
10.12 | Sierra | June 12, 2016 |
10.13 | High Sierra | June 5, 2017 |

In this post, I will show you how to install the Mac OS on VirtualBox. First of all, please download an installer.
After finishing downloading, there is one file:
Extract the file that you have just downloaded in a folder.
2- Create Mac OS Virtual Machine
On the VirtualBox, create a new virtual machine.
Enter a name for the virtual machine and select a Mac OS version suitable for the Mac OS version that you have downloaded..
Mac OS operating systems need a large amount of RAM to work, You should provide it with about 4GB RAM.
The Mac OS file downloaded by you in the above step is a complete operating system and you can be willing to use without installation. Therefore, on the VirtualBox, you only need to point to this postion of this file.
OK, your Mac OS virtual machine has been created.
You can carry out other configurations for Mac OS, for example, Network configuration, specifying the quantity of Processors,..
3- Configure VBoxManage
After you create VirtualBox virtual machine, the Meta information of this virtual machine will be found in the folder (Depending on your operating system):
- LINUX (Ubuntu,..):/home/{user}/VirtualBox VMs
- WINDOWS:C:/Users/{user}/VirtualBox VMs
There are some advanced configurations that you can perform via the interface of VirtualBox, and you must carry out it via a command:
Replace 'Your-VM-Name' by your virtual machine name. Your virtual machine name can be found in the 'Setting > General > Basic' (Like the following illustration).
On the Linux (Ubuntu,..), open Terminal windows and CD to go to your Mac OS virtual machine directory. If you use the Windows operating system, open the CMD windows with Administrator privilege and CD to go to the Mac OS virtual machine directory.
Perform the above commands respectively (after having replaced 'Your-VM-Name'):
OK, all the commands have been performed successfully.
4- Start the Mac OS virtual machine
Press on 'Start' button to start your Mac OS virtual machine:
Enter username/password (to be used to enter your Mac OS virtual machine).
OK, at this moment, you have installed Mac OS Virtual Machine on VirtualBox successfully .
