From the developer:
HextEdit is a fast and lightweight hex editor for viewing and editing binary data. The application allows you to quickly edit virtually any file type at a low level. You can edit bytes as little or big endian signed or unsigned integers, floats, or doubles. You can view values as binary, decimal, or hexadecimal numbers. HextEdit has incremental background find, allowing you to continue working while searching very large files.
You may want to check out more Mac applications, such as Libra, DataLore or NotLight, which might be similar to HextEdit.
