I use the late 2015 MacBook Pro. Before the Catalina update I was using a wireless Bluetooth mouse and it worked without any problem. Once after I update to Catalina the it completely stoped working. I unpaired the mouse and try it again and it connected but the mouse didn’t work. After that I unpaired again and tried to pair it again and now it don’t even connect to my MacBook Pro. I tried using the mouse with window computer and is worked without any problem. I figured there is an issues with Bluetooth on the new update. Can this be fixed. If so help me please.
