My iBook G4 is just 3 weeks old and I would like to re-install everything back to its brand new factory state. I have messed it up with all kinds of configurations, and dowloaded many freewares that turned out to be useless. The iBook came with a few software CDs. As I am not familiar with the Mac system, can you explain, or direct me to detailed step-by-step instructions of how to re-install everything? Thanks.
