I just got a new MBP for my business, and my wife will now use my old (still fine) PBG4 for personal use. First I want to wipe it clean and do a fresh install for her. It's totally full of crap she won't need, which has completely filled the HD and it seems has been clogging performance. Question: Can I use the install discs that came with my MBP, or do I need to use the older Tiger discs I have? I don't mind using the Tiger discs, I guess, but would like to give her the newer iLife suite that came with the MBP. Are there other advantages of using more recent install disks, if that is even possible. That's my question, actually: is it possible? I guess the biggest hiccup might be the Intel-PPC issue, or won't that matter? If I can't use the MBP discs, maybe I can just copy the iLife apps. Or will the same problems arise in that case? Any advice for me?
