Q: Magic Mouse erratic behaviour

Can anyone explain why all of the functions apart from tracking and left click behave erratically or not at all until about 20-30 minutes into a session on my iMac?

 

Secondary click and zoom work when they want to. I have tried;

  • Rebooting
  • Bluetooth on and off
  • Moving wireless devices away and switching them off
  • Turning off WiFi
  • Deleting bluetooth and mouse settings files etc

 

At present it is working ok but if I turn off the mac for a short time and go back to it then the mouse doesn't work right again.

 

I never have problems connecting.

 

Sometimes when I first turn on the mac in safari the screen will zoom in and out, scroll on its own and other similar bizarre events before calming down.

 

Any thoughts on how to resolve this as its driving me mad!!

 

Thanks

I see you are on 10.11.5 El Capitan.   Normally MM2 works perfectly as most complaints are from people with earlier OSs.   Have you tried an SMC re-set.   Another option is to download and apply the El Capitan 'Combo' update.   This option tends to rejig the system and has no effect on your files or data.

    I just had the same type problem yesterday with my own Magic Mouse. Running a mid 2010 27" iMac.

     

    The mouse was connected and functioning except I could not scroll up/down in any application. Tried several approaches.Then, I removed the back plate on the mouse. In the course of doing this, the switch was pushed to the off position. When I turned it back on and it said "connected"and functioned normally again.

     

    I still don't know what caused it. But from over thirty years of using Macs, I've learned to accept "who knows" as an answer.

    I had that happen too.    With my old Magic Mouse 1, that would normally come to light because when checking out intermittent problems you naturally turn it off, check the batteries, then after replacing them turn the mouse on again.

     

    But with Magic mouse 2 and its direct charging method, it wouldn't be so obvious.  I'll remember that.

    Just remembered I also toggled the mouse settings in System Preferences, including Tracking Speed. That was before it was disconnected, so I can't say whether it had anything to with it or not.
