how to find iHome wireless optical mouse by Sierra 10.12.6
Sierra 10.12.6 keeps sayng it cannot find the iHome wireless optical mouse. I followed the instructions: installed the optical sensor and turned on the mouse to make it "discoverable". Still no connection. One instruction I don't understand, "plug in the USB dongle to your computer". The plastic thing that must be the "dongle" is too big to plug in to a USB.
