After nearly two days of testing, I can confirm that the 2012 Mac Mini is even more sensitive than the 2011 Mac Mini when it comes to Bluetooth interference. I must admit that I hadn't actually noticed the problem on my 2011 Mac Mini because luckily my Bluetooth devices hadn't randomly disconnected like they have been on my brand new 2012 model. In my case there are two culprits causing me grief. The OWC 6G Extreme SSD and the Newer Technology Mini Stack (also from OWC). If I remove both from my 2012 Mac Mini then my Bluetooth range magically reappears and I can work again from anywhere in my Home Theatre. With them both installed my range drops to about 5 feet. If I substitute the USB3 cable supplied with the Mini Stack with a thicker one of my own then my range increases noticeably but unfortunately not enough for my needs. Any guidance on "proven" effective methods for shielding the OWC 6G would be most welcome.
