Between homebrew and nix, the amount of foss macs can run out of the box is pretty close to some generic Ubuntu (nixpkgs is technically the largest repo out there, but not all of the nixpkgs are available on mac).

There’s a whole bunch of “it loses all your data” bugs in OpenZFS too, ironically, although it’s way way less fragile than btrfs in general.

That said, the latter is pretty much solid too, unless you do raid5-like things.
