SDL2 Window lacking window bar

I'm trying to build an SDL2 app on OSX El Capitan, and I am running into an issue where the window dressing is not appearing. Things like the exit button and the resizing bar are not appearing. I've compiled on Windows and it all works fine there.

To make it a bit easier this link to Lazy Foo's tutorial replicates the issue: http://lazyfoo.net/tutorials/SDL/01_hello_SDL/index2.php

My make file is pretty simple (I've stolen it off his website as well)

COMPILER_FLAGS = -w

LINKER_FLAGS = -framework SDL2

#OBJS specifies which files to compile as part of the project
OBJS = main.c 
#CC specifies which compiler we're using
CC = g++

OBJ_NAME = main
#This is the target that compiles our executable
all : $(OBJS)
    $(CC) $(OBJS) $(INCLUDE_PATHS) $(LIBRARY_PATHS) $(COMPILER_FLAGS) $(LINKER_FLAGS) -o $(OBJ_NAME)

If anyone knows what I am doing wrong, I'd love to find out.

UPDATE: I pulled out an old laptop, fresh installed to El Capitan and it is having the same issue based on the Lazy Foo code.

            //Update the surface
            SDL_UpdateWindowSurface( window );

            //Wait two seconds
            SDL_Delay( 2000 );
        }
    }

    //Destroy window
    SDL_DestroyWindow( window );

    //Quit SDL subsystems
    SDL_Quit();

    return 0;

Not sure of the root cause but making a loop that polls events seems to do the trick.

bool loop = true;
while(loop)
{
    SDL_Event event;
    while(SDL_PollEvent(&event))
    {
        if(event.type == SDL_QUIT)
        {
            loop = false;
        }
    }
}
