-# If you are on macOS, you will need to run:
-sudo launchctl unload /Library/LaunchDaemons/org.nixos.nix-daemon.plist
-sudo rm /Library/LaunchDaemons/org.nixos.nix-daemon.plist
```
There may also be references to Nix in `/etc/profile`, `/etc/bashrc`,
and `/etc/zshrc` which you may remove.
+### macOS
+
+1. Edit `/etc/zshrc` and `/etc/bashrc` to remove the lines sourcing
+ `nix-daemon.sh`, which should look like this:
+
+ ```bash
+ # Nix
+ if [ -e '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' ]; then
+ . '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
+ fi
+ # End Nix
+ ```
+
+ If these files haven't been altered since installing Nix you can simply put
+ the backups back in place:
+
+ ```console
+ sudo mv /etc/zshrc.backup-before-nix /etc/zshrc
+ sudo mv /etc/bashrc.backup-before-nix /etc/bashrc
+ ```
+
+ This will stop shells from sourcing the file and bringing everything you
+ installed using Nix in scope.
+
+2. Stop and remove the Nix daemon services:
+
+ ```console
+ sudo launchctl unload /Library/LaunchDaemons/org.nixos.nix-daemon.plist
+ sudo rm /Library/LaunchDaemons/org.nixos.nix-daemon.plist
+ sudo launchctl unload /Library/LaunchDaemons/org.nixos.darwin-store.plist
+ sudo rm /Library/LaunchDaemons/org.nixos.darwin-store.plist
+ ```
+
+ This stops the Nix daemon and prevents it from being started next time you
+ boot the system.
+
+3. Remove the `nixbld` group and the `_nixbuildN` users:
+
+ ```console
+ sudo dscl . -delete /Groups/nixbld
+ for u in $(sudo dscl . -list /Users | grep _nixbld); do sudo dscl . -delete /Users/$u; done
+ ```
+
+ This will remove all the build users that no longer serve a purpose.
+
+4. Edit fstab using `sudo vifs` to remove the line mounting the Nix Store
+ volume on `/nix`, which looks like this,
+ `LABEL=Nix\040Store /nix apfs rw,nobrowse`. This will prevent automatic
+ mounting of the Nix Store volume.
+
+5. Edit `/etc/synthetic.conf` to remove the `nix` line. If this is the only
+ line in the file you can remove it entirely, `sudo rm /etc/synthetic.conf`.
+ This will prevent the creation of the empty `/nix` directory to provide a
+ mountpoint for the Nix Store volume.
+
+6. Remove the files Nix added to your system:
+
+ ```console
+ sudo rm -rf /etc/nix /var/root/.nix-profile /var/root/.nix-defexpr /var/root/.nix-channels ~/.nix-profile ~/.nix-defexpr ~/.nix-channels
+ ```
+
+ This gets rid of any data Nix may have created except for the store which is
+ removed next.
+
+7. Remove the Nix Store volume:
+
+ ```console
+ sudo diskutil apfs deleteVolume /nix
+ ```
+
+ This will remove the Nix Store volume and everything that was added to the
+ store.
+
+> **Note**
+>
+> After you complete the steps here, you will still have an empty `/nix`
+> directory. This is an expected sign of a successful uninstall. The empty
+> `/nix` directory will disappear the next time you reboot.
+>
+> You do not have to reboot to finish uninstalling Nix. The uninstall is

+* New experimental command: `nix fmt`, which applies a formatter
+ defined by the `formatter.<system>` flake output to the Nix
+ expressions in a flake.
+
+* Various Nix commands can now read expressions from standard input
+ using `--file -`.
+
+* New experimental builtin function `builtins.fetchClosure` that
+ copies a closure from a binary cache at evaluation time and rewrites
+ it to content-addressed form (if it isn't already). Like
+ `builtins.storePath`, this allows importing pre-built store paths;
+ the difference is that it doesn't require the user to configure
+ binary caches and trusted public keys.
+
+ This function is only available if you enable the experimental
+ feature `fetch-closure`.
+
+* New experimental feature: *impure derivations*. These are
+ derivations that can produce a different result every time they're
+ built. Here is an example:
+
+ ```nix
+ stdenv.mkDerivation {
+ name = "impure";
+ __impure = true; # marks this derivation as impure
+ buildCommand = "date > $out";
+ }
+ ```
+
+ Running `nix build` twice on this expression will build the
+ derivation twice, producing two different content-addressed store
+ paths. Like fixed-output derivations, impure derivations have access
+ to the network. Only fixed-output derivations and impure derivations
+ can depend on an impure derivation.
+
+* `nix store make-content-addressable` has been renamed to `nix store
+ make-content-addressed`.
+
+* The `nixosModule` flake output attribute has been renamed consistent
+ with the `.default` renames in Nix 2.7.
+
+ * `nixosModule` → `nixosModules.default`
+
+ As before, the old output will continue to work, but `nix flake check` will
+ issue a warning about it.
+
+* `nix run` is now stricter in what it accepts: members of the `apps`
+ flake output are now required to be apps (as defined in [the
+ manual](https://nixos.org/manual/nix/stable/command-ref/new-cli/nix3-run.html#apps)),
+ and members of `packages` or `legacyPackages` must be derivations
+ (not apps).
