Windows, MacOS, Linux...Neo runs the Trinity of operating systems.
Yes, but that's because two of those OSes allow you run them on any hardware and one doesn't. It's an artificial scarcity that's not really something to cheer about.

could run macOS on Virtual Box on PCs. It wasn't entirely stable, but entirely usable.
