I recently did a complete reinstall of my OS with my 10.3.5 backup discs that came with my iBook. Everything is fine and I've installed all the respective updates from Software Update, except that before I reinstalled I had updated up to 10.4 - now it seems the latest update is 10.3.9. When I try to download the 10.4 updates it says they cannot be run on my system (obviously, since it's a different OS version, but I was running it on my old system so I'm a little confused). Anyone have any idea what's going on with my OS? Is there a reason I was able to install 10.4 before but not now?
