Erratic Mouse

[exupery]

I am running System Version 10.8.5 on a 21 inch IMac and lately my mouse seems to be unsmooth and erratic, sometimes jumping to other parts of the screen. It is a wireless mouse that came with the computer when I bought it (3)? years ago.
Very annoying. From what I can see in a quick search I am not the only person suffering from this. Wish I could fix it since a lot of what I do requires some degree of smoothness from my mouse.

Have you tried replacing the batteries? Also, it's possible the mouse is dying, as they don't last forever.

Yes, just replaced the batteries. Actually sometimes it seems worse than others.
Maybe it should be replaced.

Have you cleaned the surface the mouse is tracking on? Because over time, little spots of dust accumulate into larger spots and start affecting the way the mouse tracks.

Turn the mouse over and blow the lint out of the opening where the tracking receptor is located.

I assume, given the age of your iMac, that it does not have USB 3.0 ports? They can cause mouse tracking problems under some circumstances.

i have the very same problem on my 5k iMac. two magic mouses and one trackpad has exactly the same issue. took it to two genius bars, they couldn't find out the problem. then i contacted apple care, have them forwarded my diagnostics files to engineering team, and they figured that there was something wrong in the firmware, and antenna. they asked me to bring my iMac to genius bar and swap the whole logic board.


but right before i was going to book an appointment for genius bar, 10.10.3 came out and i don't know how, fixed the problem.

If you are connecting to the internet by wifi I would go into router settings and set the channel to stationary 1 or the highest, 11 or whatever, and eliminate that possibility. Sometimes wifi can play havoc with bluetooth especially when on auto channel.

change channels?

We have a cisco wi fi and I have read about changing channels but where do I go to do that?
