A Raspberry Pi is technically far more powerful than was the original Macintosh, but there’s still something pleasing to me about doing it this way rather than just installing an emulator on my 4GHz Core i7 iMac 5K. The problem, of course, is that you can’t install Mac OS directly onto the Raspberry Pi-it wasn’t built for that platform-but I wanted Mac OS on the Pi because it seemed like there was a nice echo not just in how both the Pi and Mac played a part in democratizing computing but also in their hardware capabilities. The key words there were “fun” and “little,” but as the hours ticked by it was clear that “little” was laughably optimistic, and “fun” was true only in the way that a day at boot camp is fun: you know it’s good for you to be pushed out of your comfort zone and exercise bits of your anatomy that are usually blissfully underused, but you only really feel it was actually fun once you’re back at home, soaking in the tub and with a glass of port within easy reach. “I know what would be a fun little project for Think Retro,” I thought one day, like the prize chump I am: “installing a classic Mac OS onto a Raspberry Pi.”
