So I'm reselling my early 2011 Macbook Pro and the buyer asked me to put a clean install of Lion and iLife on it. I'd like to also update all the apps to the latest version though so when he gets it it's all ready to go. However, doing all of that requires making a user account after installing Lion. I'd like to install Lion, install all the updates, and install iLife and any apps he would like preinstalled, and then remove my user account and give a clean "user creation" setup screen like you get right after a clean install. The one that lets you decide on the language and set up iCloud etc. How can I do this?
