Hopper Disassembler for Mac

Hopper Disassembler — Complete reverse-engineering suite for macOS

Hopper is a macOS-focused tool that helps you inspect and understand compiled applications. It combines disassembly, decompilation, and debugging into a single interface, making it easier to explore program internals and follow execution paths. The layout and controls are designed to lower the learning curve, so even those new to reverse engineering can begin analyzing binaries quickly.

Supported architectures and file types

Hopper accepts a broad variety of processor architectures and executable formats, enabling analysis across many platforms and binaries. It can load different executable containers and provide meaningful disassembly for each supported CPU family, so you can work with most common macOS, iOS, and cross-platform binaries.

Key capabilities

• Extensible scripting and automation: write custom scripts to automate repetitive analysis tasks or extend Hopper’s behavior for special workflows.
• Live patching and experiment-driven testing: edit assembly or sample code snippets and try out changes to observe effects during debugging sessions.
• Visual code analysis and control-flow mapping: inspect function graphs, follow branch targets graphically, and understand program structure at a glance.

Extensibility and workflow integration

Hopper supports user-written extensions and automation hooks, which lets power users integrate it into larger toolchains or tailor it to specific analysis needs. The combination of a GUI and scripting makes it convenient both for one-off investigations and for repeatable, automated audits.

Who will find it useful

• Security analysts and vulnerability researchers who need to dissect binaries.
• Software developers debugging compiled code or auditing third-party libraries.
• Learners, students, and hobbyists aiming to study how compiled programs operate.

Other tools to consider

• Ghidra — a free, feature-rich reverse engineering framework from the NSA.
• radare2 — a powerful, open-source toolkit with a strong command-line focus.
• IDA Pro — a commercial, industry-standard disassembler with advanced static-analysis features.

Summary

Hopper is a practical choice for macOS users who need an approachable yet capable reverse engineering environment. Its combination of visual analysis, editable code views, and scripting support makes it suitable for both exploratory learning and professional investigation.
