Book Description
Mac OS X was released in March 2001, but many components, such as Mach and BSD, are considerably older. Understanding the design, implementation, and workings of Mac OS X requires examination of several technologies that differ in their age, origins, philosophies, and roles. Mac OS X Internals: A Systems Approach is the first book that dissects the internals of the system, presenting a detailed picture that grows incrementally as you read. For example, you will learn the roles of the firmware, the bootloader, the Mach and BSD kernel components (including the process, virtual memory, IPC, and file system layers), the object-oriented I/O Kit driver framework, user libraries, and other core pieces of software. You will learn how these pieces connect and work internally, where they originated, and how they evolved. The book also covers several key areas of the Intel-based Macintosh computers. A solid understanding of system internals is immensely useful in design, development, and debugging for programmers of various skill levels. System programmers can use the book as a reference and to construct a better picture of how the core system works. Application programmers can gain a deeper understanding of how their applications interact with the system. System administrators and power users can use the book to harness the power of the rich environment offered by Mac OS X. Finally, members of the Windows, Linux, BSD, and other Unix communities will find the book valuable in comparing and contrasting Mac OS X with their respective systems. Mac OS X Internals focuses on the technical aspects of OS X and is so full of extremely useful information and programming examples that it will definitely become a mandatory tool for every Mac OS X programmer.

Book Description
Build highly modular software in macOS that interacts deeply and intuitively with other programs. This book explores all techniques available for Inter-process communications (IPC) from high level macOS layers to deep kernel options while applying theoretical concepts into practical implementations on real world scenarios. You'll see how IPC techniques are used for exchanging data and messages among multiple threads in one or more processes, which may be running on one or more computers connected by a network or running locally. IPC methods can be divided into methods for message passing, synchronization, shared memory, and remote procedure calls (RPC). A poorly conceived IPC can even expose an entire network to over-the-network attacks. Despite the risks, processes and applications absolutely need to communicate with each other across your system and the network. You'll see how these communications facilitate information sharing, computational speedup, modularity, convenience, and privilege separation. In macOS, a program has a number of ways to communicate with other programs. These mechanisms for IPC often exist in different layers of the system. You'll examine how each has its own specific purposes, limitations, and intended scenarios. Some are more suitable than others for code written at a certain level of the system. For example, a kernel extension would not make use of Apple events. Additionally, the book reveals that different users have different rights when it comes to accessing files, changing system wide settings, and so on, depending on whether they are admin users or ordinary users. Running code with root or administrative privileges can intensify the dangers posed by security vulnerabilities. You'll learn that to elevate privileges safely, it is mandatory for the application to perform the task through a secure Helper process. You will: Expand the capabilities of your programs by sharing data within multiple applications Understand and dig deep into the world of Helper tools to create apps that need user privilege elevation Enhance the modularity of a system by allowing your applications to interact and share data with a website.

Book Description
Take advantage of the full power of Swift through XPC. Development for macOS differs from iOS and web-based development because of multicomponent applications. Besides the usual GUI-based applications and app extensions, there are a wide range of daemons—processes that run in the background—to worry about. These include system monitoring, event listening, notification agents, and many-many more. First, you'll take a tour around different types of daemons: user agents, privileged helpers, login items, XPC services, and System Extensions. Knowing key specifics of the daemons will open a wide range of possibilities from non-trivial application development to system development. You'll find lots of examples, working code samples, and even ready-to-use utilities. The book will guide you step-by-step through preparation, registration, and management of all kinds of daemons. System Extensions are brand new for macOS and open additional powerful features for developers. You'll explore installation, user flow, and communication with System Extensions, too, with examples, of course. XPC provides an object-oriented way of communication. There’s no need for custom byte/text-based protocols. A good macOS developer has to know not only programming interfaces, but also design patterns related to technology. XPC communication has a few patterns of its own, and we'll go through them all, including uni- and bi-directional communication, passing objects by-value and by-proxy, handling connection invalidation, named and anonymous connections, and many more. What You'll Learn Use multiples types of daemons in your applications Deal with System Extensions – the new type of system daemons Get acquainted with Swift bridging patterns for XPC communication Who This Book Is For Software developers and solution architects with at least a working knowledge of macOS and Swift programming. As overview, may be interested for software/solution architects.

Book Description
So, you're one of the many, the proud... the Unix geeks who've "switched" to Mac OS X. Although hacking code on the Mac is the same as hacking code on other Unix systems, you're bound to run into some problems because of the subtle differences between the Unix you're accustomed to and how things are done in Mac OS X 10.2 (Jaguar). Mac OS X for Unix Geeks was written by two long-time Unix users who've found themselves exactly where you are. It cuts through the chaff and gets right to the point on such topics as : • Using the Terminal and understanding how it differs from an xterm • Using Directory Services, Open Directory (LDAP), and NetInfo • Compiling code with GCC 3 • Library linking and porting Unix software • Creating and installing packages with Fink • Building the Darwin kernel • Running X Windows on top of Mac OS X This quick and dirty guide continues with an overview of Mac OS X's filesystem and startup processes, wrapping up with a handy reference section called the "Missing Manpages", covering Mac OS X commandline utilities not in the official documentation. Mac OS X is quickly becoming the platform of choice for Unix hackers and geeks, because it gives you what Tim O'Reilly refers to as "guilt-free computing"- a Unix system that you don't have to share with Windows. If you proudly wear the badge "Unix Geek", this book is your guide to demystifying the geekier side of Mac OS X.

Book Description
Enterprise Mac Security is a definitive, expert-driven update of the popular, slash-dotted first edition which was written in part as a companion to the SANS Institute course for Mac OS X. It contains detailed Mac OS X security information, and walkthroughs on securing systems, including the new 10.11 operating system. A common misconception in the Mac community is that Mac’s operating system is more secure than others. While this might be have been true in certain cases, security on the Mac has always still been a crucial issue. With the release of OS X 10.11, the operating system is taking large strides in getting even more secure. Even still, when sharing is enabled or remote control applications are installed, Mac OS X faces a variety of security threats, whether these have been exploited or not. This book caters to both the beginning home user and the seasoned security professional not accustomed to the Mac, establishing best practices for Mac OS X for a wide audience. The authors of this book are seasoned Mac and security professionals, having built many of the largest network infrastructures for Apple and spoken at both DEFCON and Black Hat on OS X security. What You Will Learn The newest security techniques on Mac OS X from the best and brightest Security details of Mac OS X for the desktop and server, and how to secure these systems The details of Mac forensics and Mac hacking How to tackle Apple wireless security Who This Book Is For This book is for new users, switchers, power users, and administrators that need to make sure their Mac systems are secure.
