# HookCase

HookCase is a tool for debugging and reverse engineering applications

on macOS (aka OS X), and the operating system itself. It re-implements

and extends

[Apple's `DYLD_INSERT_LIBRARIES` functionality](https://books.google.com/books?id=K8vUkpOXhN4C&pg=PA73&lpg=PA73&dq="dyld+interposing"+Singh.).

It can be used to hook any method in any module (even non-exported

ones, and even those that don't have an entry in their own module's

symbol table). In a single operation, it can be applied to a parent

process and all its child processes, whether or not the child

processes inherit their parent's environment. It supports

watchpoints. So HookCase is considerably more powerful than

`DYLD_INSERT_LIBRARIES`. It also doesn't have the restrictions Apple

has placed on `DYLD_INSERT_LIBRARIES`. So, for example, HookCase can

be used with applications that have

[entitlements](https://developer.apple.com/library/content/documentation/Miscellaneous/Reference/EntitlementKeyReference/Chapters/AboutEntitlements.html).

HookCase runs on OS X 10.9 (Mavericks) through macOS 14 (Sonoma).
