mouse disconnects frequently

I've had this mouse for several years, with my 2011 MacBook Pro, a 2014 Macbook Pro, and now with my new 2019 MBP. The mouse has worked beautifully until I bought the 2019. Why now, all of a sudden, does this mouse disconnect and re connect over and over and over on my 2019 MBP? How frustrating.

Why does my wireless mouse or keyboard slow or not work properly when used with the hub?


Most USB receivers for wireless mice and keyboards operate in the 2.4Ghz band. When connecting the receiver to any USB 3.0 port there is potential for interference that can affect the devices performance. The most effective method is to add a short USB 2.0 extension cable between the hub and the receiver to mitigate the effect, and many wireless keyboards and mice come with such a cable for this reason.

Disconnecting won't be enough if the device is still on (like a hub). Move the notebook to a location away from all the possible interference and see if the mouse works there. If not there are two possible problems: 1) the mouse and 2) the computer. No, Apple hasn't designed a computer that can't use a BT mouse. But it is possible your computer needs to be repaired.
