Читаю на каком-то форуме по поводу того, как собирать .icns-файлы (иконки на Маке):
— Try the «Icon Composer» utility under /Developer/Applications/Utilities.
— That’s what I love about Mac. All you need is already coming along with the OS :)
— Now if that’s on Windows ..... it’s called a monopoly!!!
— Mind you, if MS did provide an icon editor, it would be integrated into the taskbar and if you remove it, you wouldn’t be able to start windows.
