Out of all the Apple operating systems, macOS High Sierra is the most manageable and straightforward macOS installation on VirtualBox. Using the VMDK formatted file, we are taking a very intentional path to run the operating system in a virtualization environment.

Like our other guides, we will try to provide simple steps to install macOS High Sierra on VirtualBox on Windows PC. We’ve included screenshots for all the steps to help you through the steps outlined below and have included a detailed video to lead you through the installation visually. You will find the link at the bottom of the page.

What is VirtualBox?

VirtualBox, created by Oracle, is a comprehensive virtual machine app similar to VMware Workstation but packed with the essentials and provided free. This virtual machine application forms a sandboxed setting that can install another operating system separately from the existing operating system. This application makes the virtualization process relatively easy. While installing macOS High Sierra, we will need to make some small modifications to ensure we get the maximum use and the ability to use all its features.

macOS High SierraHighlights and Features

Similar to Mojave, Apple builds on a solid platform to advance itself to include more practical features. These new features allow users to work more efficiently, manage their time better, and stay on task. Here are just a few of the highlighted features.

Please Note: All images and files are created only for educational purposes. Any misuse of any files is not our responsibility.

What you need for this installation
– 6 GB RAM (recommend 8 GB)
– 25 GB HDD (recommend 50 GB)
– At least a dual-core CPU (recommend Quad Core CPU)
– VirtualBox Windows and Expansion Pack (found here)
– macOS High Sierra VMDK image file (found here)

Before we begin, we assume that you already have VirtualBox installed on your Windows 10 PC, with the Extension Pack installed. If you have not already done this, you can follow this guide or this video to you ready.

Part 1 – Download macOS High Sierra

  1. To get the most updated copy of macOS High Sierra, you can head over to Apple’s support website and download the image. These image files are in the DMG format and must be converted to either an ISO file format or a VMDK file format to be used to install a virtual machine. This tutorial will be using the VMDK file format because it allows for an easy installation with VirtualBox. You can get a copy of the VMDK file here. Once downloaded, keep the file in an easily accessible location.

Part 2 – Create Virtual Machine

  1. Open the Oracle VM Virtual Box Manager. At the main screen, select the ‘New’ icon at the top
Select ‘New’

2. In the first window, under the ‘Name’ field, type in “HighSierra”. Machine folder can remain as default. In the ‘Type’ drop-down menu, select “Mac OS X”. In the ‘Version’ drop-down menu, select “macOS 10.12 Sierra (64-bit)”. Click ‘Next’

Part 3 – Run Commands

Now we need to modify the VirtualBox Manager to allow us to run the macOS High Sierra smoothly without errors. Open your command prompt window by click on the Start button and type in ‘cmd’. Right-click on it and select ‘Run as administrator.

Ensure to run command prompt as administrator
  1. In the command prompt, run the first line to change the directory to VirtualBox’s default location.
cd "C:\Program Files\Oracle\VirtualBox\" 

2. Next, assuming you named your virtual machine in Part 1 StepX “HighSierra” you can copy and paste the below lines in the command window and hit enter. If you have a name, change “HighSierra” with whatever you called it, but leaving the quotation marks.

VBoxManage.exe modifyvm "HighSierra" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff 
VBoxManage setextradata "HighSierra" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3" 
VBoxManage setextradata "HighSierra" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0" 
VBoxManage setextradata "HighSierra" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"

VBoxManage setextradata "HighSierra" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1

It will look similar to the below.

You can now close out of the command prompt and head back to your VirtualBox Manager.

Part 4 – Modify Virtual Machine Settings

We need to open the VirtualBox Manager and modify a couple of settings as the last steps before installing macOS High Sierra. 

  1. Select the newly created ‘HighSierra’ virtual machine on the left side, then click on the orange settings button at the top.
click on the settings icon for HighSierra

In the menu on the left, select ‘System’, then click on the ‘Motherboard’ tab and ensure we have at least 4096 MB (4GB) of memory. Below we can uncheck the ‘floopy’ for Boot Order.

At this point, you can start using the macOS High Sierra as you please. You may notice that if you expand the window, it will not fill the screen. You may want to take an extra step and change the screen resolution with the below method.

Part 6 – Set Screen Resolution

Before changing the screen resolution to the virtual machine, exit out of the virtual machine by going to the File menu and selecting Close at the prompt, select ‘Power off the machine’.

power down the virtual machine


To get the best results, you will want to know the native resolution of your screen (i.e. 1080p is 1920×1080 or 720p is 1280×720) .

At the Windows desktop, click on the Start button and type in ‘cmd’. Right-click on it and select ‘Run as administrator .’

In the command prompt, run the first line to change the directory to VirtualBox’s default location.

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

Now you want to modify the below line to fit your needs. “HighSierra” is the name of our virtual machine and can be left as is. Where “x” is, replace it with your screen size.

VBoxManage setextradata "HighSierra" VBoxInternal2/EfiGraphicsResolution "x"

The monitor we’re using in this example is 720p, so it will look like this.

run screen resolution command

Once you have, it typed in, hit enter and close out of the command prompt.
Go back into the VirtualBox Manager, and start your virtual machine.
As it loads up, the appearance should change. Once you have logged in, you can go the the ‘View’ menu at the top and select ‘Full Screen Mode’.

enter full screen mode for macOS High Sierra

You have now entered full-screen mode and have complete the full installation of macOS High Sierra on VirtualBox on Windows PC.
