My old computer was running the latest OS X (10.4.2). The new one is Mini which has 10.3 installed. Are there specific files the Mini has to have that I have on the disks it came with (which I have)? After I get this sorted out I need to move the OS up to the latest version (do I use the newer Tiger DVD and upgrade the old one with it?) THEN move my settings and programs over from the old computer so I don't have to install about 30 new programs then set them up. That could take many hours.
