How to buy the books

• Direct (APPLE PAY ONLY): $90/book to moxii@this_domain
• Amazon (Domestic US only) - Note Amazon blacklisted my Volume I as "restricted content" - so Vol I has to be obtained directly.
• International orders welcome, but HAVE to be over PayPal, $150 per book

The trilogy is complete and all books are in their final updates. I've officially quit Darwin, but the books are and will always be available (yep. March 6^th, 2026, and they're still available) for purchase, and are so far proving future proof (though you might want to check out the New Debugging Book as well, for some minor catch ups (specifically, I/7, DYLD (chained fixups) and II/12, kernel zones, had some noteworthy changes). Everything else is still just as relevant.

• Volume I - User Mode - For some reason Amazon treats this book as "restricted content" - so you have to buy it direct from myself
• Volume II - Kernel Mode - Buy on Amazon v1.0.2 - LOG
• Volume III - Security & Insecurity - Buy on Amazon - v1.6.6 - Preview the book
