    name = "system-applications";
    paths = config.environment.systemPackages;
    pathsToLink = "/Applications";
  };

  # Set up applications.
  echo "setting up /Applications..." >&2
  rm -rf /Applications/Nix\ Apps
  mkdir -p /Applications/Nix\ Apps
  find ${env}/Applications -maxdepth 1 -type l -exec readlink '{}' + |
  while read -r src; do
    app_name=$(basename "$src")
    echo "copying $src" >&2

I used the activation script in my config, but alacritty is still not visible in spotlight :/

it does have to be an environment system package for it to be read.

this script works for kitty for example, but doesn't for wezterm because i have it as a home manager module. the creature comfort with spotlight isn't great because aliases are a little lower than a websearch. i use raycast as a spotlight replacement through homebrew.

but what is great about this script is that it gives you an opening to adapt it to add home manager aliases, just replace /Applications/Nix\ Apps to ~/Applications/Home\ Manager (i'm not a fan of bash).

Just a suggestion, I've used this utility on my flake.nix and it worked like a charm. No need to define an activation script

Do you mind sharing your flake.nix with mac-app-util? I tried it, and it doesn't work for me.

@tylercritchlow Sure! I've uploaded a copy here: https://gist.github.com/frarredondo/192930a454c992f306143bfc4eefc948

I will say that after posting my comment above i very quickly learned that very few packages were actually available for aarch64-darwin and found that i needed to install everything via homebrew so i didn't see the point in using nix at least on apple silicon atm and uninstalled it and went back to using homebrew for package management.

@ricardogaspar2 Great suggestion, works like a charm 🤝

@frarredondo Thanks for the snippet.

when I try to run the flake, I get this warning:

warning: /Applications/Nix Apps is not owned by nix-darwin, skipping App linking...

Any idea how to fix this?

@Kapi2910 - You could try to remove (or rename) the old directory, then re-run your rebuild so nix-darwin can create its symlink.
