The second reason is performance: By reducing background tasks to a bare minimum, the emulator can run on almost - but not quite - any Raspberry Pi from the Raspberry Pi 2 upwards. The first is aesthetics: The system boots rapidly and shows the Mac OS environment full-screen, making it convincing if installed inside original hardware to replace a faulty motherboard. There are a couple of very good reasons why Jaromaz sought to build MacintoshPi without relying on a graphical environment. This handy tool turns a Raspberry Pi into a classic Apple Mac, or a Commodore PET/C64/C128.
