Hello, I've searched extensively on this topic and can't find a resolution. Would love some advice / help. I just bought a new 2014 Mac Mini 7.1, replacing a 3-year old one. I'm using it as a HTPC and it's located in a closet in another room behind our TV room. I have a wireless mouse and keyboard that work very spotty / with lag. I had this issue on the old MacMini, so ran a very long USB extension cord through the crawl space and behind a panel in our TV room. I put a class 1 BT dongle on it and the mouse and keyboard worked great. No problems. Now with the new MacMini I can't get them to use the new dongle. I bought two other dongles, a Linksys USBBT100 Bluetooth USB Adapter and a IOGEAR Bluetooth 4.0 USB Micro Adapter to see if those would work and nothing. I installed Bluetooth Explorer to select the new Bluetooth device and it works worse than using the internal Bluetooth from the other room. I figured the dongle would work fine in the same room. Any advice on how to get this to work?
