That's my experience as well. A year back or so, when I had too much time on my hands, I tried myself at top. I found I had to poke in various strange places to gather all process info, and that some fields exist in one OS but not the other. I am not sure what would be easier: re-write the bottom layer of htop, or add interactivity to Mac OS X's top. A.
