For macOS 26
A hex editor for Mac that opens files read-only by default
Edits are an explicit, reversible patch layer, never a silent overwrite. Fast enough for huge files, careful enough for the ones you can't afford to break.
-
Read-only by default
Files open read-only. Editing is an explicit toggle, and every edit lives in a reversible patch layer with per-patch revert.
-
Byte-exact on huge files
The grid scrolls the entire file via a proportional scroll surface. Jump, search, bookmarks, and structures all navigate byte-exactly, with bytes read on demand through an LRU chunk cache.
-
A real inspector, not a sidebar afterthought
Inspect selection summaries, byte values, and encoding previews; Analyze hashes, strings, anomalies, and structures; Annotate with bookmarks and binary diff.
-
Explainable analysis with Apple Intelligence
On-device Apple Intelligence explains a selected range of bytes and turns plain-language requests into searches. Analysis only, never a way to mutate bytes.
-
Safe by construction
Overwriting the original requires confirmation and offers an automatic backup first. Save a Copy and every export goes through a standard save panel.
-
Fully native, fully sandboxed
Swift 6, App Sandbox with user-selected file access, security-scoped bookmarks for recent files, and a layered Liquid Glass app icon.
