Okay, so I got a Macbook to replace my old 900MHz iBook.

I used the automatic transfer thing that my Macbook prompted me to do - but here's the issue: I believe I had some, well, some crap on the old computer that got transfered over (Old library files, ect), and for the life of me I can't get MacPython to work on the Macbook, which is rather upsetting as I am an amature programmer.

I was wondering if there was any way to detect uneeded files and delete them, or if i should just reinstall the OS, and just put back the music/movies/reinstall the programs.

Thanks,
Massasoit.
