+## Use Docker for Mac and Windows (Edge) to connect to swarms
+
+On Docker for Mac and Docker for Windows current Edge releases,
+you can access your Docker Cloud account and connect directly to your swarms through those Docker desktop application menus.
+
+* See [Docker Cloud (Edge feature) in Docker for Mac topics](/docker-for-mac/#docker-cloud-edge-feature)

+
+> **Tip**: This is different from using Docker for Mac or Windows with
+Docker Machine as described in previous examples. Here, we are
+by-passing Docker Machine, and using the desktop Moby VM directly, so
+there is no need to manually set shell environment variables.
+
+This works the same way on both Docker for Mac and Docker for Windows.
+
+Here is an example, showing the Docker for Mac UI.
+
+1.  Make sure you are logged in to your Docker Cloud account on the desktop app.

+
+2.  Choose the swarm you want from the menu.

+
+3.  A new terminal window opens and connects to the swarm you chose. The swarm name is shown at the prompt. For this example, we connected to `vote-swarm`.
+
+    ```shell
+    [vote-swarm] ~
+    ```  
+
+4.  Now, you can run `docker node ls` to verify that the swarm is running.
+
+    ```shell
+    [vote-swarm] ~ $ docker node ls
+    ID                            HOSTNAME                                      STATUS              AVAILABILITY        MANAGER STATUS

 If you accidentally unregister a swarm from Docker Cloud, or decide that you
