Project Bluefin. Basically an immutable base like MacOS with a ton of preconfigured development tools. Installed in despair at mucking about getting something working under Fedora Silverblue - which is great but doesn't wholly integrate Distrobox (easy to rectify though, it's just a Podman front end) and is very fiddly to get working with Qemu and Virt-manager (Qemu is less fiddly than Virt-manager, but they both required layering the base OS or quite esoteric Distribox or Podman configurations that were not ideal). If it wasn't for that Silverblue does everything I need. At a certain point the luxury of having time to muck about runs out
Basically a Linux disto for Mac users. Which has the disadvantages of MacOS and the advantages of MacOS. Linux with far less mucking about. The concomitant gaming version is called Bazzite.
