Are you looking to run macOS High Sierra on your Windows or Linux machine? VirtualBox, a powerful open-source virtualization software, makes this possible. In this guide, we'll explore how to create and use a macOS High Sierra VirtualBox image, ensuring a seamless and secure virtual environment.
Why Use macOS High Sierra in VirtualBox?
Running macOS High Sierra in VirtualBox offers several benefits. It allows you to test macOS applications on your primary OS, run macOS-specific software, or even develop macOS apps without purchasing a Mac. Moreover, it's an excellent way to learn and experiment with macOS without committing to a dual-boot setup.
System Requirements
Before we begin, ensure your host system meets the following requirements:

- 64-bit processor
- At least 4GB RAM (8GB recommended)
- At least 20GB of free disk space
- Virtualization support enabled in BIOS/UEFI
Obtaining the macOS High Sierra Image
Since Apple doesn't allow virtualizing macOS, we'll use a third-party tool called Anything to create a macOS High Sierra image. Download the latest release from the GitHub repository and extract the 'macOS High Sierra.app' file.
Creating the Virtual Machine
Now, let's create a new VirtualBox machine for our macOS High Sierra image:
- Open VirtualBox and click on 'New'.
- Name your VM (e.g., macOS High Sierra), select 'Mac OS X' as the Type, and 'macOS (64-bit)' as the Version, then click 'Continue'.
- Allocate at least 2048MB of memory, then click 'Continue'.
- Create a new hard disk (VDI), select 'Dynamically allocated', then click 'Continue'.
- Choose 'Create new hard disk', then click 'Create'.
- Select 'VDI (VirtualBox Disk Image)', then click 'Continue'.
- Choose 'Dynamically allocated', then click 'Continue'.
- Set the file location and size (at least 20GB), then click 'Create'.
Configuring the Virtual Machine
Before we can use our macOS High Sierra image, we need to configure the VM settings:

- Select your VM and click on 'Settings'.
- Go to 'System' and ensure 'Enable EFI (special OSes only)' is checked.
- Go to 'Storage' and click on the 'Empty' CD icon under 'Controller: IDE'.
- Click on the disc icon next to it, then select 'Choose/Create a Disc Image...'.
- Browse to the 'macOS High Sierra.app' file you extracted earlier, then click 'Open'.
- Go to 'Display' and increase the video memory to 128MB.
- Go to 'Network' and ensure 'Enable Network Adapter' is checked.
- Click 'OK' to save your changes.
Installing macOS High Sierra
Now, let's install macOS High Sierra on our VirtualBox machine:
- Select your VM and click on 'Start'.
- In the 'Create new virtual machine (recommended)' dialog, click 'Continue'.
- Choose 'I Agree' to accept the license agreement, then click 'Continue'.
- Select 'Install macOS', then click 'Continue'.
- Wait for the installation process to complete. This may take several minutes.
Post-Installation Setup
After the installation is complete, you'll need to perform a few post-installation tasks to ensure your macOS High Sierra VM runs smoothly:
- Install the VirtualBox Guest Additions to improve graphics, mouse integration, and other features.
- Update your VM's settings to match your host system's resolution and enable 3D acceleration.
- Install any necessary software or drivers for your specific use case.
That's it! You now have a fully functional macOS High Sierra VirtualBox image ready for use. Happy virtualizing!
