The Minecraft world insulates its inhabitants from information about the host computer's hardware and physical environment, including whether it runs on a Mac or PC.

“For instance, the world of Minecraft. You can walk around in the world of Minecraft, and it's running very well on a Mac, and it's running very well on a PC, and if you are inside of the world, you don't know what you're running on, right?”

“It's not going to have any information about the nature of the CPU that it's on, the color of the casing of the computer, the voltage that the computer is running on, the place that the computer is standing in in the parent universe, right, our universe.”
