Not able to test Led

I am not able to test led which is connected with GPIO…As i am not finding device testing option in my mac machine

You can test your led connected with gpio correctly if you follow the instructions given in your Bolt IoT app installed in your app, or if you are mentioning about some thing else then please mention again with details, thank you.

can you explain your query in detailed way?? It is easy to solve your issue if you add screenshot of it too.
Thank you.
