Apple mac mini did not read my bluetooth mouse and therefore, did not go to set- up mode.  After much frustration, I called Apple to find out why and they said it is a pain to troubleshoot.  I bought another mac mini from Apple online- and that didn't work either.  I get an appointment at an Apple Store and the tech guy said the mac mini was not reading both the mouse (Logitech) or my Apple keyboard.  Bluetooth had to be set up and you can't do that first.  Now it all works and I'm happy.
