+/path/to/carla/Dist/CARLA_Shipping_0.9.13-...-dirty/MacNoEditor/
+```
+
+This folder can be moved to another place if you prefer.
+
+The build folder includes the compiled server app for Mac `CarlaUE4-Mac-Shipping.app`.
+
+To run the server in headless mode, to be used by a client, you can run the following command in the terminal. This mode loads faster, and it delays around 20 seconds to be ready for the client:

+```
+open CarlaUE4-Mac-Shipping.app --args -RenderOffScreen
