I was excited to receive my refurbished iMac.  It was well packaged and looked like it was brand new.  It came with a new mouse and keyboard also.  I followed the prompts, downloaded some OS data, so far so good.  When asked to choose a destination disk for the OS, there was none.  I worked with Amazon customer service for hours with no results.  I tried the company that refurbished the iMac but got no answer after 5 tries.  Had to return it.
