PeekIt hex editor for Mac

If you really want to get up close and personal with your computer, there's nothing that beats a hex editor. While Word can open DOC files, and Firefox can display HTML, a hex editor lets you open and look at anything on your system. It's not always going to be pretty in there, since the hexadecimal data you're looking at is designed for your computer's CPU rather than your eyes, but sometimes that's what you need.

Maybe you're got a data file that you don't have the application for. With a hex editor, you can open that old WordStar or VisiCalc file and see what's really in there. Since it's a native Mac application, it knows all about data-and resource forks, so you can really get in there and look around. It's safe for you to go in, since it won't write anything back to the file until you explicitly tell it to do so. You can even make annotations to your files that are kept in separate .pinotes files, so you can keep track of what you're seeing in there.

PeekIt is a free Mac application. This tool requires OS X ver 10.4 or later.
