An in-depth look into Mac OS X and iOS kernels

Powering Macs, iPhones, iPads and more, OS X and iOS are becoming ubiquitous. When it comes to documentation, however, much of them are shrouded in mystery. Cocoa and Carbon, the application frameworks, are neatly described, but system programmers find the rest lacking. This indispensable guide illuminates the darkest corners of those systems, starting with an architectural overview, then drilling all the way to the core.

  • Provides you with a top down view of OS X and iOS
  • Walks you through the phases of system startup—both Mac (EFi) and mobile (iBoot)
  • Explains how processes, threads, virtual memory, and filesystems are maintained
  • Covers the security architecture
  • Reviews the internal Apis used by the system—BSD and Mach
  • Dissects the kernel, XNU, into its sub components: Mach, the BSD Layer, and I/o kit, and explains each in detail
  • Explains the inner workings of device drivers

From architecture to implementation, this book is essential reading if you want to get serious about the internal workings of Mac OS X and iOS.


Peeling Apple's Operating Systems
System-level developers, kernel hackers, and intrigued Apple-lytes, take heed: This book lets you explore the nooks and crannies of Mac OS X and iOS, delving into the architecture of both systems, and picking up where the frameworks (and documentation) leave off. It offers clear, detailed explanation of the inner workings of Apple's systems, including proprietary APIs, most of which are documented for the first time.
As you traverse the architecture, moving from user to kernel mode, each layer and component is unraveled with annotated code samples and hands-on experiments, comparing and contrasting its implementation in both OSes. Topics include:
* The boot process: Mac's EFI, iOS's iBoot, and kernel startup
* Processes, threads, and virtual memory management
* Debugging and profiling, using DTrace, ptrace, and hidden system calls
* The system level APIs: POSIX calls, Mach traps, and OS X/iOS proprietary
* File system architecture, including VFS and HFS+
* Network architecture: from sockets to interfaces, and network drivers
* Kernel extensions, drivers, and a discussion of I/O Kit architecture
* Security features, Mandatory Access Control, and iOS jail
The companion web site ( includes sample programs, freely downloadable tools, updated references, and bonus additions.

As the author states in the Introduction: “This book aims to do for XNU what Bovet & Cesati's Understanding the Linux Kernel does for Linux, and Russinovich's Windows Internals does for Windows.” Knowing only the latter book, I would say that authors intention have been perfectly fulfilled. For those, which also knows Russinovich's and Solomon's standard work enough said.
For those others: The author understands his matter. He not only describes, but also make understand. To make a picture, the potentially reader should go to [...]. There he can read the Contents of the book and also download a full text of ( very important ) chapter 4. There are also some little tools ( with source code ) for delving deeper into OS X and iOS. Giving the tempo with which operating systems evolve, the book is pretty actual ( Lion ). You have not to read it from page first to page last, but you will be often happy to have it in the bookshelf. And you have not to be an expert in C or Assembler to profit from it ( although having some elementary knowledge of C would enlarge the pleasure ).

Nachdem es lange zeit nur ein vergleichbares Buch für PowerPC -Macs gab, endlich eines, dass sich mit den Intel-PCs beschäftigt. Trotz der schweren Kost leicht geschrieben und sehr lehrreich.

5.0 von 5 Sternen Awesome 2. November 2012
Von Daniel Zimmerman - Veröffentlicht auf
Format: Taschenbuch Verifizierter Kauf
So I've got an entire bookshelf dedicated to lower level software books and this is by far the most versatile and most information packed. It is incredibly terse and comprehensive. I can see anyone from just an average user that wants to learn about macs to a senior developer who has much experience in c and even objective c but not necessarily the inner workings of Darwin find a lot of use from this book. I have not finished it yet (its almost 1000 pages) but I have already learned enough to fill 10 buckets. What I also love is how it refers to other books that go far more in depth on each topic. So yes in a sense this book is comprised of summaries but they still go in depth enough for one to understand the gist of whats going on. I can say from the start that the chapter on EFI is pretty phenomenal and that coupled with all the information on the mach architecture has taught me an incredible amount. Overall if you are interested in learning about macs and how they work, or are a programmer and want to learn how to take advantage of some lower level stuff or if you're more in the hacker field and enjoy seeing how things work under the hood and how you can manipulate them to your advantage (me) you will definitely enjoy this book.

5.0 von 5 Sternen Excellent book! 11. Dezember 2012

Format: Taschenbuch
This book is a result of an extensive, epic research made by the author. Yes it is all open source, you could go an read the code to understand the architecture - but this is why you have books! It covers the subject really thoroughly and written in an easy to read format. The book contains some amazing reverse engineering work which is just cool and revealing things never covered since Amit's book. I wonder what Apple engineers think of this book. I bet they could buy it for their new recruits!

5.0 von 5 Sternen A Perfect Security Resource as Well 18. Dezember 2012
Von Jason Haddix - Veröffentlicht auf
Format: Taschenbuch Verifizierter Kauf
Doing iOS and Mac OSX security research becomes pretty hairy with the mountain of code and nature of objective-c and ARM. This book provides a reference that has just simply not been available in any other book. Our mobile penetration testers at Fortify are all reading this release right now and signing it's praises. We look forward to it aiding our automation efforts in identification of security vulnerabilities of iOS code. Also, the new command line tools and descriptions of them alone are worth the book cost.

4.0 von 5 Sternen A worthy successor. 3. November 2012
Von RichL - Veröffentlicht auf
Format: Taschenbuch Verifizierter Kauf
This is best book on OS X internals since Amit Singh's Mac OS X Internals: A Systems Approach, and certainly a good companion to the iOS Hacker's Handbook.
It covers OS X up to Lion and iOS up to iOS 5, which is understandable as it would be almost impossible to publish an up to date book given Apple's release schedule.

I would certainly recommend this to people look for a modern OS X internals reference.

3.0 von 5 Sternen Revise needed 2. Juli 2014
Von Brandon - Veröffentlicht auf
Format: Taschenbuch Verifizierter Kauf
It is true that reading a kernel book can be difficult and not fun, but the problem of this book is beyond this.
If you read the table of content, it looks like this book covers a lot of aspects. Providing "Mac OS X Internal" is somewhat "outdated", this book might be the only one you can get in the market. It does cover a lot of aspects, but leaves none of them discussed in-depth. For example, VFS. It is sad that Mac OS X Internal doesn't really cover a lot on VFS. I bought this book, hoping that it could discuss more about Mac OS X VFS, but I was disappointed. It covers even less. The VFS Mac OS X is using now was a fork of FreeBSD. They share a common ancestor at some point of time, then they diverged.If you look into the current FreeBSD VFS, it's very different with the one Mac OS X is using. So you cannot simply depend on a FreeBSD kernel book. I don't want to make my code dirty, I always want to make sure I have a good understanding of all the assumptions of VFS interfaces before I move on. The fact is that, there's no single book on shelf can reach this goal. Apple doesn't have a good documentation of their VFS, either. So as an independent developer, reading Apple's existing code (devfs for memory based VFS, HFS for block device based VFS) seems to be the only way to learn it.
Beside the above problem, another big issue is the typos and errors in this book.
There are quite a number of typos. Most of them don't cause real trouble since you can correct them by yourselves, but some of them are really misleading. Like on page 348, the first parameter of mach_msg call should be a pointer type, but the star is missing. I stared at it for a minute and looked at the real source code, proved that the book was wrong. Other errors also make glitches while reading. Like, when talking about the internal Mach IPC mechanism, the book states that we've talked about semaphores. I was surprised, because I'm always a careful reader, but I didn't remember I've read any kernel synchronization stuff from the book. Later on I realized that the synchronization part was moved to after the internal IPC part. So the actual ordering of topics of that chapter is different from the one printed on the first page of that chapter. This kind of mistakes should have been avoided by carefully reading before publishing, but sadly that was not the true story.

As a conclusion, if you are look for a book that can give you directions of possible solutions of your current questions/problems, it is okay. It also lists references at the end of each chapter. But if you are looking for some in-depth discussion, you might find some luck with Mac OS X Internal, though that book is really outdated. However, not every single problem has a perfect solution. For example, I really wanted a book that talks more about Mac OS X VFS, but there's just no such thing in the market.
