Hello, I have a G4 with OS10.2.8. I would like to update the system software, I know that most of the programs on it will no longer work, but I'd like to back up everything to an external hard drive. Is there a way to do it? Most new hard drives need OS10.5 so I don't really know how I would be able to do that. My main concern is the 9000 photos I have in iPhoto. I'd like to put them all on a hard drive that we could hook to our tv and see the photos in a slideshow. Thanks for any help.
