Same, tried Nix on my macOS (MBA M1) back in January. The installation is painless but it ran into an issue in the first run after it. It looks like that I skipped a step somewhere, I was following the guide and it should be working but its not. I suspected it was the guide that someone forgot to include it in the documentation or edge case I experienced. Now the uninstalling part is painful because there bare minimum documentation about this. Tried all different way to remove it and I couldn't. Took me a month to finally remove Nix from my macOS, I found the information through SO.

I had the same exact same experience. If the uninstallation wasn't such a pain in the ass I might even give nix another try in the future.
