This is for someone who is using Swift and NSStoryBoardSegue, here is the same way to achieve it

NSApplication.sharedApplication().mainWindow?.close() // close current window first
self.performSegueWithIdentifier("id_of_your_segue", sender: self) // open the second view by invoking the segue that is set to connect  two views.
