Hi,
You need to compile the missing module from source.
Please follow the steps below:
- Install xcode from apple app store
- unreal engine editor (4.10, 4.11, 4.13 or later)
- Create a new C++ code project without starter content
- Copy all files from SampleProject directory to your new project directory
- In UE4 editor File -> xcode project (optional)
- Exit from unreal engine editor
- your new project from epic launcher
- Click on rebuild missing DLLs when prompted
- Optional: Click on File -> Package project -> OSX
