In your Storyboard, select your second Window Controller. In the identity inspector, specify a name for this window controller, e.g secondWindowController

Then, in your app delegate, set up a property for the window controller:

@property NSWindowController *myController;

In your applicationDidFinishLaunching: method implementation, create a reference to the Storyboard. This way you get access your window controller from the storyboard. After that, the only thing left to do is to display the window by sending your window controller the showWindow: method.

#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate
@synthesize myController;

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSStoryboard *storyBoard = [NSStoryboard storyboardWithName:@"Main" bundle:nil]; // get a reference to the storyboard
myController = [storyBoard instantiateControllerWithIdentifier:@"secondWindowController"]; // instantiate your window controller
[myController showWindow:self]; // show the window
}

@end
