I use my 2011 MacBook Pro in a dock and use the Apple wireless keyboard and magic trackpad. Ever since I upgraded to a thunderbolt dock and usb 3.0 drives, when ever I'm transferring a lot of data on the drives or doing a Time Machine backup my mouse and keyboard are just about unusable. They either become jerky and lag or just connect then disconnect over and over again. Ive been dealing with this for a couple of months now. Ive been so fed up with it that I've gone back to the wired keyboard and a crappy windows mouse to bypass the issue. I really miss the trackpad and keyboard for the gestures and the clean wireless look. Ive tried just about everything to combat the issue such as locating the mac closer to the devices and moving the hard drives further away. Ive even swapped the usb cables out for better shielded ones with no success. Is there anything else that I could do to improve the bluetooth reliability?
