I came across <https://archive.org/details/raspberry-mac> this Mac emulator image. It was put together by the fellow that created the Frog Find search engine. It is a 10GB image that needs to be written to a 32GB micro SD. This uses QEMU running on a base install of Raspberry PI OS on a Pi 3 or better. It emulates a PM G3 running either OS X 10.2 or MacOS 9.2.2. On my Pi 3B+ it is very very slow to boot and use, however it is very "authentic". When you power on the Pi you get a boot chime and it goes into a very stock boot and typical OS9/10 desktop It first boots into MacOS 9.2.2. The Startup control panel can be used to select whether you want to boot into 9 or into Jaguar. Jaguar supports the classic environment. All in all it is very intriguing. As noted it is very slow on the Pi 3B+ and my guess it would take a Pi 4/400 or Pi 5 to get decent performance. All of the configuration and specific code used is open sourced. |

One reason I find QEMU unacceptable is precisely the performance: you can get a huge overclocked PC and it still will not even beat a G3, let alone a higher end G4 (i.e.: Mac mini). Then there's also the FPS issue: every PPC Mac emulator is stuck at 30 FPS at best, which is outrageous to me. QEMU can be compiled at least for GNU/Linux to run at 60 FPS, but oh boy, you need quite the rig to make use of that (and to figure out how to compile such a thing), and even then it will still be slow or incompatible due to no GPU passthrough nor acceleration for whatever software that needs it. Hopefully we will get more new Mac hardware made, or booting the OSes natively in more devices. To me, it's either that, or nothing.

Every tutorial I have seen concerning setting up MacOS in QEMU uses the Beige G3 as the model to emulate. I am not sure that is the best choice of hardware to emulate, but it does appear to be the hardware most understood for emulation configuration purposes. And it is the machine that will boot Classic MacOS, as well as OS X with a functional "classic environment". The problem on the Pi is one of i/o and RAM. A micro SD card is makes for very slow reads and writes and the 1GB of RAM, is small by today's standards for even running a current OS, even before before adding the overhead of emulation. The Pi setup takes 3 minutes to get to the desktop, takes 45 seconds to launch textedit. Then takes another 45 seconds to save the 1K text file and exit. Besides being fond of Solitaire, I do not do gaming. In fact for the bulk of what I do color seems more distracting than useful. Even with Sonoma on a machine with multiple GPUs and goods of resources, I go settings and bump the contrast up to high and switch to greyscale. Color is for the natural world, today I think all screens should be e-ink.

I'll bet it'll run ShapeShifer and Basilisk pretty well! And check this out...this is with a much less power pi, definitely won't be running MacOS X on it, but a 128k original Mac...no problem: https://www.theregister.com/2024/06/18/apples_macintosh_128k_on_a_pico/
