I'm not entirely clear what you want, but it sounds like you just want
the badged icon image, rather than actually badging your app's icon
(for display in the dock, say). You could try something like this:

NSImage *appImage = [NSImage imageNamed:@"MyAppIcon"];

NSImage *badge = [NSImage imageNamed:@"MyBadgeImage"];
[badge setScalesWhenResized:YES];
[badge setSize:NSMakeSize(64, 64)];
       
[appImage lockFocus];
[badge compositeToPoint:NSMakePoint(aPointX, aPointY)
operation:NSCompositeSourceOver];
[appImage unlockFocus];

[myImageView setImage:appImage];

Of course, you'll want to play with the sizing and placement of the
badge to get it right. And you'll need to "borrow" a badge image from
somewhere. If you want to badge the actual icon as it appears in the
dock, app switcher etc, then use [NSApp
setApplicationIconImage:appImage].

Hope this helps.
