Last month, Apple released their final version of MacOS Sierra. If you have decent hardware with enough CPU, RAM, and storage space, you could create a MacOS Sierra virtual machine using VirtualBox on a Windows host. Thanks to TechReviews, you can download a VMDK image file to create your virtual machine.

To use VMware Workstation 12 Player instead of VirtualBox, see how to Install MacOS Sierra 10.12 on VMware Player on Windows.

Downloads

First, you’ll want to download and install VirtualBox v5.x.

Next, you’ll want to download the VMDK MacOS Sierra image (choose one of the options below):
Google Drive (One Full): https://goo.gl/m1an1R
Google Drive (5 of 5): https://goo.gl/I7DCqA

You’ll probably get a message about the download limit has been reached. If you have enough free space in your Google Drive, you can copy it into your Drive. Right-click on the file and select Make A Copy. Then click on My Drive in the left menu and download the image from your drive.

After you download the image, open the .rar file and extract the VMDK file.
