About:
Ldid is a tool designed to inject code signatures into Mach-O binaries, commonly used for iOS and macOS development. It allows developers to sign applications for testing on non-jailbroken devices or to apply fake signatures for debugging purposes. This Procursus build is optimized for modern environments and provides a reliable alternative to Apple's codesign utility for specific workflows.

Key Features:

Injects ad-hoc signatures into Mach-O binaries
Supports both real and fake code signing
Lightweight and fast compared to official tools
Essential for iOS development and jailbreaking workflows

Use Cases:

Signing iOS applications for sideloading onto devices
Debugging and testing apps without full Apple Developer credentials
Modifying existing signed binaries for research or patching

Alternatives:

codesign – Apple's official tool; requires full developer credentials and is more complex for simple signing tasks
jtool – Alternative Mach-O manipulation tool with broader features but less focused on code signing
