Well the point is I didnt want to do erase and install
The person I'm handing it down to is still sorta new to Mac and I kinda have everything nicely setup right now. Adium, iWork all the essentials. I just want to wipe preferences clean. Like Adium account settings and the like, logs, cache, bookmarks, browsing history, you know personal stuff so its sorta a clean slate.
Onyx sounds good enough though. I might have to manually delete the rest of the stuff.
