I’ve managed to get NixOS running on an 8gb MacBook air which tools a bit of tweaks but asahi installer sets everything up where you can boot and install from NixOS
edit: The minimal UEFI part of the Asahi installer specifically sets up a “normal” environment that other distros (like Nix) can use, it doesn’t actually install a full distro like Asahi Fedora
Apple makes great hardware (even more so now with their own CPUs) but I've steered clear of it simply because I run Linux. Last I checked the GPU wasn't fully supported and there were also concerns of of efficiency, that power draw is generally higher than macOS, thus the same hardware on Linux doesn't have the same benefit as with macOS.
