The Mac mini would not connect to any of my Apple Bluetooth devices. This was very frustrating as I could not do initial set up without having to purchase a wired keyboard. The Bluetooth mouse connected, but was intermittent. After purchasing wired mouse & keyboard, I was able to do initial set up & reset system preferences for bluetooth to connect wireless mouse & keyboard. I wish I knew that this was an issue prior to purchasing & setting up. Everything seems ok (for now). Keeping my wired keyboard & mouse (just in case).
