Hello Everyone, My wife has a ti-book 1 ghz, she is running 10.3.9 on it. Is it fine to put 10.4.11 on? She expressed concern that she had heard it wasn't good to put 10.4.? on some time in the past. If you would email me directly, I'm in digest mode right now and don't have time to fiddle with it. macstonelson at yahoo.com Thanks. Dave
