recovery mode not seeing bluetooth mouse or keyboard
I just got a new 27" iMac and I'm trying to prepare my late-2015 iMac running Catalina to send to Apple for trade-in value. I follow the instructions recieved to to erase the hard drive by first going ionto recovery mode - pressing the Cmd+R keys on start up. When I do this the machine will not go into recovery mode - it just keeps looking for a BT keyboard and mouse. I have both next to the computer charged. They worked fine prior to trying to go into recovery mode.
