I tried Nix while ago when NixOS made news in HN. You are right, it is difficult to set it up. Eventually I give up on it and tried to remove Nix from my macOS, let say it is difficult to remove Nix as well. I tried their command line to remove Nix and it didn't remove it even with sudo. Nix been sitting on my macOS for a month since it couldn't remove it completely. I realized I just have to go to Disk Utility to dismount/remove the Nix VHD and then ran the command line again which finally got it removed from my OS.

Hm, that's a good point.

Removing Nix is easier on operating systems where root is root (normal Unix-likes without a lot of filesystem-related security policies enabled). Nix only uses a separate APFS volume on macOS because Apple disabled writing to /.

The way that affects the uninstall process should be documented.

I spotted some people who've recently worked on Nix's install scripts and uninstall procedure elsewhere on the thread. You can file an issue if you think they'll miss your comment :)
