The problem is the following, I have two MacBooks, (MacBook A and MacBook B) and a trackpad.
When I connect (via Bluetooth) the trackpad with MacBook A, everything is fine. Later I turn off that MacBook A and turn on MacBook B. I connect (via Bluetooth) the trackpad to MacBook B, everything fine.
Much later, I turn off MacBook B and turn on MacBook A, the trackpad does not connect, although I see it in the list of Bluetooth devices I can not connect, I have to choose "forget device" and pair again; The same happens every time I switch MacBook between A and B.
Any idea?
