Magic mouse stuttering and lacks response with OSX Catalina
Since upgrading to OSX 10.15.x (I'm on .3 at the moment) I have been unable to use my Magic Mouse 2 for long on my MBP. It seems to start OK but after a while it stops responding properly - sometimes stuttering, sometimes the response is delayed, sometimes it simply doesn't respond. After a while it may return to normal or it may not. Often I need to turn it off and then on again, sometimes several times, to get any response.
I bought a new Magic Mouse 2 just in case it was the old one but the problem persists.
I have reset NVRAM, reinitialised Bluetooth, removed and reconnected the mouse, and generally wasted a lot of valuable time trying to solve the problem, even going as far as changing the mouse mat, just in case.
Anyone else have this problem and, preferably, a solution that doesn't involve any of the above?
