I want to give a Mac mini away for a couple of days to someone who would want to play with Mac for the first time. Is there a way to return OS X to a state where you find it straight after fresh OS X installation when Mac needs to be taken through registration process, given name, etc. I want to install all the accompanying software like iLife'05 and apply all the recent OS and iLife updates and then "reset/deauthorise" OS X so that the new user did not have to install apps and download updates the first thing after powering the Mac up and going online. If you are familiar with what sysprep does to Windows, that's what I am looking for Mac OS X. I assume the process should include removing all the user accounts, deleting assigned Mac name and kicking in a registration app at startup. I just hope one does not need to buy OS X server for that!
