Hopper Disassembler
Hopper Disassembler is a native macOS reverse engineering app for analyzing, decompiling, and exploring executable binaries.
What is Hopper Disassembler?
Hopper Disassembler is a developer tool for reverse engineering compiled software on macOS. It helps security researchers, malware analysts, and low-level developers inspect executable files, study assembly code, and understand how a program works internally. The app provides disassembly views, control flow graph navigation, and C-like pseudocode through its decompiler, making complex binaries easier to examine. Hopper is commonly used to analyze Mach-O files and other supported executable formats during debugging, research, compatibility work, and software auditing. It is published by Cryptic Apps and offered as a native Mac application, with Linux versions also available from the same product line.
Key features
- Disassemble executable binaries into readable assembly code
- Navigate program structure with an interactive control flow graph
- View C-like pseudocode through the built-in decompiler
- Analyze Mach-O files and other supported executable formats
- Annotate functions, addresses, and code paths during research
- Use a native macOS interface with keyboard-friendly navigation

Safety overview
Status: Safe
Hopper Disassembler is legitimate reverse engineering software for developers and security professionals. It is designed to open and analyze executable files, so it may expose sensitive code or embedded data from the files you load into it. That access is normal for its purpose. Use it with trusted samples when possible, and be mindful that opening proprietary or confidential binaries can reveal information you may not want to store in project notes or exports.
Recommendation: Keep Hopper Disassembler if you use it for reverse engineering, binary analysis, debugging research, or security work on your Mac. If you no longer inspect executables or decompile binaries, you can remove it like other developer tools without affecting macOS itself.
