Book Description
In this second volume of the “Mac OS and *OS Internals” trilogy, Jonathan Levin takes on the kernel and hardware aspects of Macs and i-Devices. Starting with an examination of the kernel sources, then going off the beaten path to undocumented portions, especially in the *OS variants. This book explains in detail the various components of XNU – BSD, Mach, platform expert, Kernel Extensions and the IOKit environment. It goes further into memory management (vm_map , pmap and the kernel zone allocator), processes, threads, Mach IPC internals, the Virtual Filesystem Switch, and more. Never before published details about the Apple File System (APFS), Secure Enclave Processor OS (SEPOS), iBoot, Mac EFI and more are explained in meticulous detail and fine illustrations. Numerous experiments allow a hands-on approach, making this invaluable to anyone who wishes to learn more about how the XNU kernel operates – and how to interface with its darkest and most powerful mechanisms. This book is only offered for direct purchase via newosxbook.com, where it also has a fully searchable online index.
