0xED
0xED is a lightweight hexadecimal editor for macOS, designed for inspecting and editing binary files at the byte level. It allows users to view and modify file contents in hexadecimal format with simultaneous ASCII display, making it useful for reverse engineering, file format analysis, debugging binary data, and exploring system files. The app targets developers, security researchers and power users who need direct access to raw file bytes.

1 suggestion0xED was discontinued by its developer and has not received updates in many years. The latest build is Intel-only (x86_64) and contains no Apple Silicon (ARM64) support. It continues to run under Rosetta 2 on current M-series Macs, but Apple is removing Rosetta 2 in macOS 28 (September 2028), after which this app will stop launching entirely. There is no native version forthcoming from the original developer. If you rely on 0xED for hex editing, consider switching to actively maintained alternatives that run natively on Apple Silicon: Xcode (free from Apple, includes a built-in hexdump viewer and binary editor), the free Hex Fiend (available on GitHub), or the paid Synalyze It Pro — all offer similar byte-level inspection capabilities and are under active development. Begin migrating your workflow to one of these alternatives before the September 2028 deadline.
