Q: Mouse stops working at random in El Capitan

I have a late 2008 Mac Pro running El Capitan for a few days now and everything works except the mouse; the mouse service stops working.  I tried disabling the "shake mouse to locate" feature but that did not fix the problem.

 

I was using a USB mouse but then switched to an Apple Wireless mouse (Bluetooth) and the same thing happens only now I get a nice message on the screen alerting me that the mouse was disconnected, awesome!

 

Any help will be greatly appreciated as I don;t want to go back to Yosemite.

Mac Pro, OS X El Capitan (10.11)

    Chris ...

     

    There can be more than one reason why you see the mouse was discounted dialog.

    Carolyn thanks for your reply but I am having the same problem with a USB mouse.  The problem seems to be on the OS side and not the peripheral.  When it stops, I can connect and disconnect any mouse and it will not work.  Only rebooting makes it work.

     

    This is why I think it is the mouse service and not the mouse that has the problem.

     

    Also worth noting, I have been running Yosemite for almost a year on the same hardware and never had this problem.

    Hi Carolyn,

     

    I am having the same issue as Chris. My mouse is connected but it's not tracking. I just updated to El Capitan yesterday. All troubleshooting suggestions in the link you provided have not resolved this problem. Any suggestions?

     

    Thank you

    Do you have any third party mouse drivers installed?

    No third party mouse drivers.

     

    I did have a Microsoft wireless touch mouse and a regular Microsoft USB mouse installed, but I did not install any drivers manually.  Unless they got installed automatically without my knowledge.

     

    I have to report that when I made this post, my newly installed Apple Magic Mouse (Bluetooth) had just stopped working so I assumed it was the same problem, however after replacing the batteries on it, I have not had any issues at all with it.

     

    I have not tried with an Apple branded USB mouse so I'm not sure the problem is only with other brands and I happen to only have two Microsoft mice so I am not sure what the problem is.

     

    As far as I'm concerned it' working now so I guess I fixed it myself but using an Apple branded device, weird right? Or is it?
