I want to sell my iMac (2011) and I want to reset the system and remove all my data. I tried the Command-R method. It wants me to enter my Apple ID and password but I don't want to do this! I want to pre-install the fresh OS X and let the new user finish the set up as he would after buying a new iMac (enter/create his own Apple id, time zone, etc.).
Any ideas how I can do this?
