I have an iBook G3 800MHz with 384MB of RAM and just got the iLife 05 install DVD. (I understand that Tiger and iLife 05 are the best the iBook G3 can run.) iMovie HD and Garageband are installing fine. iDVD won't install of course because it requires a G4 -- and I don't have a DVD burner anyway. But the iLife installation had iPhoto grayed out. I couldn't select it for installation, although the machine meets the requirements. Why? I had previously dragged iPhoto 06 into my /Applications from another Mac in target disk mode, but deleted it (by dragging it to the trash) because it wasn't technically supported. Is there some piece of iPhoto 06 left installed somewhere that is preventing iPhoto 05 being installed as part of iLife 05? Maybe it thinks I have a newer version installed?
