深入剖析 Mac OS X 与 iOS 内核。驱动着 Mac、iPhone、iPad 等众多设备，OS X 和 iOS 正变得无处不在。然而在文档方面，它们的大部分核心内容依然笼罩在迷雾之中。Cocoa 和 Carbon 等应用程序框架虽然有详尽的描述，但系统程序员却发现其余部分语焉不详。这本不可或缺的指南照亮了这些系统最隐秘的角落，从架构总览入手，随后层层深入直至核心。- 为您提供 OS X 和 iOS 的自顶向下全景视角 - 带领您走过系统启动的各个阶段——包括 Mac (EFI)

……这些年来陆续被废弃了，包括像网络栈这样的 POSIX 特性，如今已被 Objective-C API 取代。我建议抽空读读《Mac OS X Internals: A Systems Approach》和《Mac OS X and iOS Internals》这两本书，了解一下仅仅把所有东西都放在 kernel space，并不会把原本的微内核代码重写成一个庞大的巨石单体。
…been deprecated along the years, including POSIX features like networking stack, now replaced by Objective-C APIs. I would advise spending some time reading "Mac OS X Internals: A Systems Approach" and "Mac OS X and iOS Internals" books, to learn that having everything on kernel space alone, doesn't rewrite the original microkernel code into a huge monolith.
这话一听就是从来没读过 Apple 官方文档，也没看过有关 Apple 平台系统编程的 iDevice 相关文献的人说的。你可以先从《Mac OS X Internals》开始读，接着读《Mac OS X and iOS Internals: To the Apple's Core》。然后再去逛逛 Apple 的归档文档库，https://developer.apple.com/library/archive/navigation/
Says someone that never read Apple documentation or iDevice literature regarding system programming on Apple platforms. You can start by reading the Mac OS X Internals, followed by Mac OS X and iOS Internals: To the Apple's Core. Then hop over to Apple's archive, https://developer.apple.com/library/archive/navigation/
不会，因为很自然地，它们的需求类型完全不同，而且空间也是有成本的。从技术上讲它们算是一码事，只是配置的功能集不同而已。虽然已经有点年头了，推荐《Mac OS X and iOS Internals: To the Apple's Core》https://www.amazon.com/Mac-OS-iOS-Internals-Apples/dp/111805...
No, because naturally it is different kind of requirements and space is at a price as well. Technically it is kind of the same, but with different set of configured features. Already a bit oldie, "Mac OS X and iOS Internals: To the Apple's Core" https://www.amazon.com/Mac-OS-iOS-Internals-Apples/dp/111805...
Apple 借用了 BSD 的零碎组件。macOS 并不是“FreeBSD”。引用 Jonathan Levin 在《Mac OS X and iOS Internals》中的话：“在 Mach 之上，但仍然作为 XNU 不可分割的一部分，是 BSD 层。这一层提供了一个坚固且更现代的 API，提供了前面讨论过的 POSIX 兼容性。……
Apple uses bits and pieces of BSD. macOS is not "FreeBSD". Quoting from Mac OS X and iOS Internals by Jonathan Levin: "On top of Mach, but still an inseparable part of XNU, is the BSD layer. This layer presents a solid and more modern API that provides the POSIX compatibility discussed earlier. The…
除非你已经把所有版本的《Windows Internals》、《MAC OS X Internals: A Systems Approach》、《MacOS and iOS Internals》、《Mac OS X and iOS Internals: To the Apple's Core》都吃透了。或者你曾经是微软或苹果负责内核底层开发的员工，那我或许还会听听你觉得它们到底有多水的看法。但我总隐隐觉得，……
Unless you have mastered all editions of Windows Internals, MAC OS X Internals: A Systems Approach, MacOS and iOS Internals, Mac OS X and iOS Internals: To the Apple's Core books. Or having been a former Microsoft or Apple employee working on kernel stuff, then I could eventually value the opinion how fake they happen to be. Yet somehow I get the feeling,…
