The one thing that I absolutely cannot stand about my OS X workflow is that to this day, I still have not found a good hex editor. On Windows I used HxD, but there's nothing that really fits the bill. That, IDA Pro (I don't have an OS X license and from what I hear the OS X version isn't too spectacular anyways), and Visual Studio are what make me occasionally boot into Windows.

HexFiend[1] doesn't do the trick? (I have only occasionally need for a hex editor, but it serves well when the need arises.)

I believe I tried it once, but the UI wasn't very appealing to me. The key features I'm looking for are: fixed width of 16 bytes, clean interface, process inspecting (not sure how easy that is to do to be honest) and raw disk access.

You might want to try 010 Editor: http://www.sweetscape.com/010editor/ It runs on OSX, Windows and Linux.

Does it run on Linux? There doesn't seem to be any mention of that on the downloads page.

No, it doesn't. My mistake.
