Truly unforgivable - and potentially illegal.  I just received this iMac.  Upon the very first power on, it went though language and WiFi network selection as normal, and then went to a remote management screen that cannot - repeat cannot - be bypassed.  This machine is still registered to the Hoffman Estates High School and requires the user to login in order to complete setup.  Obviously, I'm in no way part of that educational institute.Further as in theory this machine was advertised as "Renewed", I find it highly questionable that there could have been ANY inspection done with this unit other than the exterior.  It is bluntly impossible that this could have been done.  In other words, this is a scam, falsely claiming the product was "renewed" when absolutely nothing other than looking at the physical exterior is even remotely possible.  The iMac was not renewed.  It was simply stick in a box and shipped.  I am seriously disappointed and am reporting this fraud to Amazon.  Bluntly, for all I know this computer was stolen.
