I have a mamba i bought so that i could use a mouse in WIndows bootcamp while still using my trackpad in Mac OS. Simple idea right? First off I was a dumbass because in AMazon I searched bluetooth mouse and mamba came up which is not BT. But forging ahead I installed it on the Windows OS. Bottom line is that the mamba dongle seems to capture the mouse / trackpad capabilities in Mac even not installed and I now cant even repair the trackpad in Mac or Windows until I remove the dongle and delete every trace of it. Anyone trying to do the same that might have advice?
