Hello. User of Yosemite. I am worried about my system calling constantly to Apple. I want a completely autonomous operative system. But Yosemite has so many services turned on to be in touch with Apple. I don't want that. I don't want sync via Apple, I don't need social daemon, I don't have iPhone to accept calls, I don't need backup my mac, I don't need iCloud and everything else. I need a operative system that contacts the Internet only when I give direction for it. Why do I need it? Yes, for nothing illegal. If I trash my computer, everything what is on it will disappear. I don't want that any corporation has my data, even metadata. How to prevent OS X calling Apple, AWS and others?
