The UseBorderlessWindow setting appears to not be implemented on Mac. We currently only apply the NWWindowStyleMaskBorderless style for tooltips and other "irregular" windows, so we may need an additional check here to apply that style if the borderless checkbox is checked.

if( Definition->IsRegularWindow )
{
	if( Definition->HasCloseButton )
	{
		WindowStyle = NSWindowStyleMaskClosable;
	}
 
	// In order to support rounded, shadowed windows set the window to be titled - we'll set the content view to cover the whole window
	WindowStyle |= NSWindowStyleMaskTitled | (FPlatformMisc::IsRunningOnMavericks() ? NSWindowStyleMaskTexturedBackground : NSWindowStyleMaskFullSizeContentView);
	
	if( Definition->SupportsMinimize )
	{
		WindowStyle |= NSWindowStyleMaskMiniaturizable;
	}
	if( Definition->SupportsMaximize || Definition->HasSizingFrame )
	{
		WindowStyle |= NSWindowStyleMaskResizable;
	}
}
else
{
	WindowStyle = NSWindowStyleMaskBorderless;
}
Steps to Reproduce
  1. Check "Use Borderless Window" in project settings
  2. Launch in standalone, and note that the window is not borderless
