BuildPlayer says successful but there is no .app to run

I am interested in doing build batches with Unity's command line tool on OSX, but when I run the tool, I never get a .app file to use. I only generate a Contents folder.

I run this command in my terminal /Applications/Unity/Unity.app/Contents/MacOS/Unity -batchmode -projectPath /Users/andymartin/Code/tests/TestTools -executeMethod BuildMe.MyBuild -quit

The editor says that my build was succesfull. I had an error before where it wasn't finding my scene file, but I corrected it by putting tin the correct path.

Here is my class using UnityEngine; using System.Collections; using UnityEditor;

 public class BuildMe
 {
     static void MyBuild()
     {
         string[] levels = new string[]{"Assets/tester.unity"};
         BuildPipeline.BuildPlayer(levels, "MacBuild", BuildTarget.StandaloneOSXIntel, BuildOptions.AutoRunPlayer); 
     }
 }
