Apple Wireless Keyboard circa 2010
My old MacPro 5,1 (MP)died and was replaced by a Mac Studie M-2 Ultra. I would like to use the old MP Apple Wireless Keyboard circa 2010. Studio's BlueTooth (BT)can see the keyboard, but when I select "connect" nothing much happens. I suspect that the old keyboard is still paired to the deceased MP. How do I un-pair the keyboard or any other suggestions?
