With both pieces of software installed, create the virtual machine the following steps: If not, both can be downloaded from this page.
Copy over the iso created in the previous step and make sure both VirtualBox and its extension pack are installed.
Switch to the Windows 10 machine in which you want to set up the virtual machine. Before running the script, make sure the installer variable points to the right location of your High Sierra installer. Note that this is the original script, and it was written assuming that the High Sierra installer was downloaded from the App Store into the Applications directory.

Installer="/Applications/Install macOS High Sierra.app" The only way I could get an iso that worked on VirtualBox was by using the script suggested in this answer: Once you have a copy of the High Sierra installer, an iso file must be prepared to install it in the virtual machine. In the menu bar, select Tools > Download macOS High Sierra…Īfter a few minutes, you should have a copy of the High Sierra installer. Once the tool is downloaded, open it and use its built-in downloading feature. I downloaded a copy through this macOS High Sierra Patcher Tool for Unsupported Macs. High Sierra can still be downloaded from third-party websites. However, High Sierra is no longer available for download from the Apple App Store. Downloading High SierraĪt the time of this writing, High Sierra was the most recent version of Mac OS X that could be installed in a VirtualBox virtual machine. I used a Mac in the first two steps and completed the last two steps on the target Windows machine.
On top of that the process to install OS X in to a VirtualBox VM requires having the OS X installer as an ISO image.
If it was a dog you would have it put down. Apart from the lack of Mac guest additions, you can only allocate a single CPU core, you are limited to a specific screen resolution, speed is awful, and I am not even sure copy&paste works. VirtualBox is extremely horrid for running Mac VM guests, the most polite comment I can provide is that it can be done.
