O.K., I'm fairly new into my mac. Today I have been searching for a utility to wipe free space on my macbook. I'm looking for something open source/freeware. When I was using Windoze I used Eraser by Heide. I can't find a thing out there. Oh, and I've done a search here in the forums and after looking through multiple pages I haven't found anything that meets my needs. Sorry. I'm pretty frustrated. And pardon my ignorance in all things Mac.
