but other times the truth of facts is more nuanced. Change for change's sake is also wrong. Apple isn't stupid . They know that Macs and iOS devices are solid platforms, successful in their own ways. Macs are used by writers, engineers, architects, fashion and graphic designers -- you name it. Macs allow Apple to make a profit off computers , they expand the userbase, and -- an often abused expression -- they "lock you into an ecosystem". Again, from my Mountain Lion review: To sell more Macs, Apple knows it has to focus on building a better experience because it's not just about the hardware -- if it were, people would be buying more specced-out Windows PCs or assembling their own Linux boxes. Hence, Mountain Lion, and its replication of much of the iOS experience. By making it easier to move between iOS devices and the Mac, Apple's message is clear: different devices serve different purposes, but the core experience will be the same, and it will free you from worrying about data loss and dealing with unintuitive metaphors. Some people fail to understand that making things more familiar across the board doesn't mean we're doomed. If the "Why would Apple change OS X?" isn't enough as a question , let's proceed down to Level 2 and see how it makes sense as a fact . Changes introduced in OS X include Gatekeeper and Sandboxing . These technologies are, according to Apple, aimed at making Macs more secure. Sandboxing
