Leave your Mac alone for a few minutes and it becomes a 1990s PC: an AWARD BIOS counts through 32 MB of RAM, a VGA prompt starts blinking, and then a ghost begins to type. It boots. It crashes. It dials. It lies convincingly.
Welcome, traveller. You have just discovered FakeDOS, a macOS screen saver that simulates a pixel-perfect DOS machine. And more.
Leave your Mac alone for a few minutes and something beautiful is going to happen: the screen fills with the warm 80×25 glow of a VGA text mode, an AWARD BIOS POST clicks through memory, and a friendly blinking C:\> prompt appears.
Leave the prompt idle and a ghost starts typing commands by itself. It alternates between operating systems in an endless loop of simulated productivity.
