Why Magic Mouse curser does not move?

Easy solution : I got the same issue with my magic mouse 2. scroll works well but curson moving like drunken guy. when i saw the bottom of the mouse the lazer light is also clear. but i just took a small tissue and wiped those bulbs to make sure. then its started working nicely , then i found the reason that the laser bulbs are covered with some cream or oil, it can be anything , just try wiping the bulb @mouse bottom using some tissue paper , it should work.

Had the same problem. Here's the process I went through to getting it working again:

Tried fresh batteries. Clicks worked, but no mouse tracking.

Another set of fresh batteries. The same result.

Tried removing and re-adding the mouse in the Bluetooth Preferences. No difference.

Found a blog post that suggested cleaning the battery contacts. Mine looked nice and shiny, but I scrubbed them anyway. Still no good.

Went into Bluetooth preferences, highlighted the mouse then under the gear menu, clicked ""Update Services"" then ""Monitor Connection RSSI"". Monitor Connection RSSI opened a new window with a graph. It took a few seconds for it to start plotting data, but as soon as it did, the mouse began working correctly.

Delete the extension named USBOverdrive.kext in the extensions folder under \System\Library\Extensions. Restart the computer and it work."

"Sometimes the Bluetooth mouse and sometimes even the USB wired mouse stops moving properly.

That is usually caused when the laser lens gets dirty.

Get a Q-tip or a small cloth like from a cotton tee shirt. Moisten it with rubbing alcohol, (not the drinking kind). Clean the lens thoroughly, then try the mouse again. If it still does not move, and the batteries are good, then its time for a new mouse."

"I took a cue tip and went over the the tracking lenses. Boom it works again :)

I did the same thing to my ears but I still cant hear well. So I have to replace the tracking lenses in my ears. :("

"Hey Azmir

As everyone has explained, the lens on the bottom of the magic mouse sometimes becomes dirty, smudged, and even some cases can develop scratching.

Most of the time the problem is the mouse not recognizing the movement of your hand. This is because the laser can't detect a surface. As everyone has said, check the clarity of the lens first. If you have done so and the problem still persist, check the bluetooth connection. Make sure there are no other connected mice, usb mice, or other unknown bluetooth devices in the ""Bluetooth"" pane.

Assuming this is the original Apple Magic Mouse check the terminal connections for the batteries too. If there isn't enough power circulating the mouse due to corrosion of the terminals, some features or normal behavior may diminish."
