Cant see device in Monodevelop ( to attach)

I followed all the instructions such as switching script debugging on and stopping the run in xcode but when I go back to monodevelop and try to attach to a process my device doesn’t show.

I’m on unity 3.5.

They are both on the same network and I’ve tried to create a separate one on my mac and connecting to that but it still didn’t show.

I’ve also tried restarting both unity and my device.

Any thoughts on why it’s not showing up?

Thanks

Try reinstalling the win or the unity and it will work Because that happened to me once
