Okay, I'm using a macmini for my entertainment system. MacMini is on the other side of the room, tv is on the other. My keyboard works fine, but my mighty mouse doesn't do so well. (both apple products) I bought another mouse (logitech) It doesn't look so pretty, so i wanted to see if i can extend the range of the bluetooth with a usb extension and Bluetooth to usb adapter. Will it work with my apple products (keyboard,mighty mouse). do i need to disable the internal BT on my mac? My main question is, will i have any effects on having two BT receivers in my mac. Will my mini only use one of them, that one being the internal and NOT the external i want to purchase. Any comments are greatly appreciated.
