Like many other people who found that their bluetooth mouse or trackpad "jumped around" when using their macbook closed with an external monitor, I solved the problem with an external bluetooth dongle.


The "jumping around" problem is caused by the internal bluetooth antenna in the macbook pro having poor reception when the case is closed.


I used the popular IOgear Bluetooth 4.0 USB dongle.  With this external USB dongle, my trackpad worked perfectly.


Under Mountain Lion, the OS recognized that a newer bluetooth device than the one built into the laptop was available, and just started using it.


Under Mavericks, the OS is back to using the internal bluetooth, and I can't figure out how to force it to use the external dongle.



MacBook Pro, OS X Mavericks (10.9)
