Byte Chaser Mac OS
Imagine... you have a binary file and don't know its contents. Or some software creates binary files you have a specification for but don't want to decode them manually.
Have you ever looked at hex dumps and felt how hard it is to make sense of it? And to remember the meaning of all the bits and bytes?
Synalyze It! allows you to create a “grammar“ for your binary files interactively. Unlike in regular hex editors or viewers the files are interpreted automatically for you! Analysis of binary files has never been easier.
Additionally Synalyze It! is a full-featured Hex Editor for Mac OS X allowing you to edit files of unlimited size and interpret the bytes with dozens of text encodings.

- This tool can easily be installed on Mac OS X using Homebrew. Hping is another free command-line tool derived from ping. It is available on Mac OS X as well as most Unix-like operating systems and Windows. Although it is no longer in active development, it is still in widespread use, a testament to how good a tool it is.

When these are clipped or soldered onto the 68000 processor, a 32 MHz 68030 processor can be used, and up to 16 MB RAM. This allows it to run Mac OS 7.6.1. There is a program available called Mini vMac that can emulate a Mac Plus on a variety of platforms, including Unix, Windows, DOS, classic Mac OS, macOS, Pocket PC, iOS and even Nintendo DS. OS X is the worst of the lot. Each queue is limited to 2048 bytes and OS X silently ignores attempts to increase this (just like FreeBSD). To add insult to injury, there appears to be no way to increase this limit short of recompiling the kernel. I'm guessing at this based on the Darwin message queue limits.
Essentially it’s a modeling tool for arbitrary file formats that is being used by software developers and data stream experts as well as in computer forensics.
The grammars are stored as XML files and contain all the structures that may occur in a file of a certain format, just like XML schemas. It’s even possible to inherit structures from others (like in OO languages) so you don't have to repeat for example a length field that appears at the beginning of each structure.
Synalyze It! is an extremely flexible and useful tool for viewing binary file data. It enables you to easily apply a structured format to your file bytes and convert them into meaningful displays of data.
Synalyze It! provides formatters for common binary types like ICC, PNG, TIFF, WAV, ZIP and dozens more. That alone is useful but, if you’re a programmer creating a custom binary file format, Synalyze It! is priceless.
With Synalyze It!, you can create custom data formatters for your personal binary files. Instead of struggling with cryptic lines of hexadecimal, you can view and label data values as floating point or integer, signed or unsigned, with any byte length. Your files can even modify the formatting, allowing you to create settings on the fly to variably view your data.
If the standard formatting tools are not enough, you can write formatting scripts using Python or Lua. I quickly got ambitious and was soon in over my head exploring Synalyze It!’s features. When I emailed a question to the developer, the technical support was outstanding. I was sent a complete solution to my problem that also served as an advanced Synalyze It! tutorial.
I doubt that I will ever fully exploit the potential of Synalyze It! but the value I’ve received is already many multiples of the price I paid.

For some well-known formats you can download grammars here. Matching grammars are suggested automatically when you open a file.
Right now you can download Synalyze It! for Mac OS X and give it a try. In case of questions or problems please give me feedback. The latest changes can be tracked here; stay tuned also on Twitter.
If you like Synalyze It! consider buying the Pro version in the Mac App Store.
The Pro version has even more useful features beyond hex editing.
Hi,
I just bought the pro version of Synalyze, and I am very glad I did. Thank you for taking the time to bring this excellent tool to life.
I’m the author of an open-source program called SleepyHead, which is used for reviewing CPAP machine data (used in Sleep Apnea treatment), and already I’m wishing I discovered Synalyze a lot sooner, as an awful lot of binary format hacking is involved thanks to the manufacturers not releasing documentation.
I particularly like being able to use expressions in the length fields.. I spent ages looking through the example grammar and scripts only to find I didn’t even need them thanks to this feature. (It pays to read the manual first.. ;)
Keep up the good work!
Regards

Mac Hex Editor for Professionals
There are some hex editors for Mac available but only Synalyze It! allows to create a grammar for automatic file decoding in a specialized grammar editor.
- Simply open the file you want to analyze
- Create an empty grammar
- Select bytes in the hex editor and add an element or structure to the grammar using the context menu
- Enhance the grammar in the grammar editor

Other special features of Synalyze It!:
- Supports various encodings like ASCII, EBCDIC, UTF-8 or UTF-16 (see ICU for all supported encodings)
- Lets you easily see if a file is compressed with the histogram view
- Opens even huge files ultra fast by loading only the visible part of a file
- Hex editing works with the same mouse and keyboard commands like in common text editors
