Hex Fiend is another hex editor for the Mac. Native and fast. http://ridiculousfish.com/hexfiend/

Or do it with a one liner

perl -pi -e 's/VACUUM/xxxxxx/g' /Applications/Spotify.app/Contents/MacOS/Spotify

I've always liked 0xED (http://www.suavetech.com/0xed/0xed.html)

If you're looking for vi, but for binary, bvi does the job.


Or use hexl-mode in Emacs

I'm pretty sure vi itself, or at least vim, is fine with binary files. You can run it as `vim -b` or `:set binary`.
