Answer 1

First, determine which screen you want to use by iterating over [NSScreen screens].

Create a full screen window with:

NSScreen *screen = /* from [NSScreen screens] */
NSRect screenRect = [screen frame];
NSWindow *window = [[NSWindow alloc] initWithContentRect:screenRect
    styleMask:NSBorderlessWindowMask
    backing:NSBackingStoreBuffered
    defer:NO
    screen:screen];
[window setLevel: CGShieldingWindowLevel()];

You might want to google CGDisplayCapture() as well.
