Path Finder has a built-in basic Hex Editor/Viewer. It can be also used in any Preview pane to quickly preview a binary file without having to open a dedicated application.
With a hex editor you can:
- manually inspect files for quality, when writing a program that outputs binary data
- open or preview corrupted or invalid files
- recover or analyze corrupted files
- make precise edits to a system file, such as changing a memory address in a kext
We recommend to always duplicate a file before editing its hex code.
