What's a good hex editor/viewer for the Mac? I've used xxd for viewing hexdumps, and I think it can be used in reverse to make edits. But what I really want is a real hex editor.

The answer is
The one that I like is HexEdit Quick and easy to use
- Open file with Xcode and press Command + Shift + J
- Right click file name in left pane
- Open as -> Hex
One recommendation I've gotten is Hex Fiend.
To view the file, run:
xxd filename | less
To use Vim as a hex editor:
- Open the file in Vim.
- Run
:%!xxd(transform buffer to hex) - Edit.
- Run
:%!xxd -r(reverse transformation) - Save.
There are probably better options, but I use and kind of like TextWrangler for basic hex editing. File -> hex Dump File
I have recently started using 0xED, and like it a lot.
On http://www.synalysis.net/ you can get the hex editor I'm developing for the Mac - Synalyze It!. It costs 7 € / 40 € (Pro version) and offers some extra features like histogram, incremental search, support of many text encodings and interactive definition of a "grammar" for your file format.
The grammar helps to interpret the files and colors the hex view for easier analysis.
