Logitech MX Master 2s not linking on iMac on a start up
When I start my iMac, OS10.13.6 I get a pop-up message looking for Blue tooth device mouse. Logitech MX Master 2s not linking on a startup. Then when I wiggle the mouse it activates and the pop-up message disappears. Is the reason because the mouse is asleep? Any solution?
Thanks.
