Hello dear members of the iBook list, I read very carefully all your messages concerning my post about installing OSX (10.0) on my Clamshell graphite. I had some doubts, now I don't have any. The little baby will run with OS 9.2 period! The reason why I was willing to give it a try is that my everyday Mac is an old 6500. So the Clamshell is my most "recent"!!! I wanted to feel OSX. I think I'll be looking for a used G4 over 500 mhz with a 17 or 19 inches monitor. And I love so much my Clamshell. Dunno why, I just love it. Thanks again for your precious help Germain
