Hi. Received payment for my iBook last night and purchased a Macbook at the local Apple store. Need to deliver the iBook tonight and wanted to reinstall everything fresh (and clear the hd so that none of my history, files, extra applications are cluttering the hard drive for the new owner). Also wanted to do my fresh install on my Macbook as cleanly as possible. I've heard you can skip installing foreign language packs and a few other things to really save some hard drive space. Can anyone help me? I need to know how to do each of these, more importantly the first. Thank you.
