I'll really appreciate your help.

Answer 1

What you're referring to is known as a splash screen. Here's a beginner-friendly tutorial on creating one in objective-c.

Answer 2

Turn off "Title Bar" of the window in Interface Builder (in the window's attribute inspector).

If you are creating this programmatically, the property you are looking for is "styleMask". These are the available masks:

enum {
   NSBorderlessWindowMask = 0,
   NSTitledWindowMask = 1 << 0,
   NSClosableWindowMask = 1 << 1,
   NSMiniaturizableWindowMask = 1 << 2,
   NSResizableWindowMask = 1 << 3,
   NSTexturedBackgroundWindowMask = 1 << 8
};
