Hi, this is my first post here. I've done a lot of searches on this forum and others but am still confused about a few things. I'm considering buying a used ibook, powerbook or maybe a macbook. What I'm concerned about is what they come with as far as software, OS and the like. Are they all supposed to have iLife stock? Is that something that comes preloaded or on a disk? But further more I'm concearned about licensing. If I get a used laptop I assume the seller will either wipe the hard drive or leave it. If they wipe it I guess I need install disks for the OS as well as any software (like iLife)? If they don't wipe the harddrive will I still be able to use all the programs left on and update them? What if it comes with non-apple programs? It seems warranties and Applecare are transferable but what about software? Any other things I need to consider when buying used? Thanks in advance!
