+### Using Tun mode in MacOS
+To use Tun mode in MacOS, you need to open the app as root.
+
+Open the app like this:
+
+```shell
+sudo /Applications/nekoray.app/Contents/MacOS/nekoray
+```
+
+It will open a Nekoray instance with no configurations; if you have configured your Nekoray in normal mode, close the app and do this to copy them:
+
+**`Note:`** Replace `YOU` with your username
+
+```shell
+sudo cp -r /Users/YOU/Library/Preferences/nekoray/ /private/var/root/Library/Preferences/nekoray
+```
+
+Now, you can open it with the first command.
