When selling computers running Tiger I would always set up an admin account, preinstall some software, and then reset the computer back to the intro movie so that when my buyer would turn on the computer, it would greet him with the intro movie and setup. He/she could then set up their own account and then delete the admin account I had set up earlier. This was the only way I knew of to sell a computer with software preinstalled, and still offer a great first experience for the buyer. This is the command I would use in terminal, sudo mv /private/var/db/.AppleSetupDone /private/var/db/.setupnotdone After that, I'd shut down the computer, turn it on to test it, and then shut it down once I saw that it worked--and then I'd send it off. Can anyone verify that this still works in Leopard?
