I am using a Magic Trackpad 2 with a KVM, over USB, which seems to work fine, the Trackpad controlling the cursor only on the active computer. However, if I turn on the Macbook Pro's Bluetooth, when I switch to the other computer, both computers are getting the Trackpad's feed (so both cursors move, and clicks go to both). I can see this on the laptop's screen, when the cursor moves off the shared display.
I use Bluetooth for other devices, so I'd prefer to leave it on, but there is no option in the Bluetooth control panel to "Unpair" or "Disconnect" the Magic Trackpad, as there is for other devices (such as my phone). Currently, turning off Bluetooth on the MBP is the only solution I've found.
Is there a way to stop the MBP from pairing with the Magic Trackpad (or, in this case, to unpair them -- permanently)?
