title: Failed to start iOS Simulator in the mac
body: <p>I have a Xamarin.Forms project.</p>
  
  <p>I'm using vs2015.</p>
  
  <p>Today I updated Xamarin to the latest version:4.0.0.1697.</p>
  
  <p>When I tried to connet my mac as the Xamarin Mac Agent, vs shows the message below:</p>
  
  <p><strong>Starting Agent Build 4.0.0.1697...</strong></p>
  
  <p><strong>Failed to start iOS Simulator in the mac</strong></p>
  
  <p><strong>An error occured starting the Build 4.0.0.1697 agent: The operation has timed out.</strong></p>
  
  <p><strong>Starting Agent Designer 4.0.0.1697...</strong></p>
  
  <p><strong>An error occured starting the Designer 4.0.0.1697 agent: The operation has timed out.</strong></p>
  
  <p><strong>The Xamarin Mac Agent could not be fully started. Agents not started: IDB 4.0.0.1697, Designer 4.0.0.1697, Build 4.0.0.1697. Please check the logs for more details.</strong></p>
  
  <p>So I can't debug the ios app.</p>
  
  <p>I don't know how to do next.</p>
