-# 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.

+> 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
+> complete. macOS (Catalina+) directly controls root directories and its
+> read-only root will prevent you from manually deleting the empty `/nix`
