Apple's initial Magic Mouse and the follow-up Magic Mouse 2 exhibit few quirks. You may not think about the Magic Mouse until it suddenly stops tracking, the cursorbecomes jerky,orthe cursor moves super slow or super fast. When your Apple mouse is not working, there are several fixes you can try.

Instructions in this article apply to the Magic Mouse 2 and the initial Magic Mouse connected to a Bluetooth-enabled Mac computer with macOS Catalina (10.15) and higher.

How to Fix Magic Mouse Tracking Problems

Most of the fixes for an Apple mouse not working correctly are simple. Try these solutions to get your mouse up and running in almost no time.

1. Reseat the battery if you use a first-generation Magic Mouse and experience hesitant tracking behavior. The most likely reason is that the batteries in the mouse lost contact with the battery terminals. The result is that the Magic Mouse and Mac momentarily lose Bluetooth connectivity. To see if the mouse has a battery connectivity problem, lift the Magic Mouse off of the surface you're using it on. If the green power LED blinks, the batteries are probably loose.

2. Recharge the built-in battery in your Magic Mouse 2. It doesn't have the battery terminal problem because it doesn't use standard AA batteries. Instead, Apple created a custom rechargeable battery pack for the second-generation mouse that you can't access. Check the battery charge by clicking theBluetoothicon on the Mac menu bar or in the Mouse preferences. If the charge is low, take a break and plug it in.

3. Clean the wireless mouse's dirty optical sensor. If you have a Magic Mouse 2 or can rule out a battery problem in your first-generation Magic Mouse, the mouse may be skipping or hesitating because debris or dirt is lodged in the mouse's optical sensor.

   

   To fix this issue, turn the mouse over and use compressed air to blow out the dirt. If you don't have compressed air on hand, blow into the sensor opening. Before putting the mouse on your work surface, clean the mouse pad or desktop area where you use the Magic Mouse.

4. Change the Magic Mouse's speed or sensitivity. Go toSystem Preferences>Mouse>Point & Clickor System Settings>Mouse>Tracking speed. If the Tracking speed slider is set to either an extremely slow or extremely fast speed, adjust it to a speed that suits you better.

5. Delete a damaged preference file. The preference file that your Mac uses to configure the Magic Mouse when you first turn it on may be corrupt. Access the Library folder on your Mac, locate the ~/Library/Preferences folder, and drag the following two files to the trash:

   • com.apple.AppleMultitouchMouse.plist
   • com.apple.driver.AppleBluetoothMultitouch.mouse.plist

   When you restart the Mac, it recreates the default preference files for the mouse. OpenSystem Preferences or Settingsand reconfigure the mouse to meet your needs.

   The ~/Library/Preferences file is hidden on a Mac by default. Access it by going toFinder>Go>Go to Folderand typing~/Library. Then selectGo.

6. Make an Apple Genius Bar appointment or take the mouse to an Apple Authorized Service Provider to evaluate and, if possible, repair the mouse. If these fixes don't solve the problem, you may have a hardware issue on your hands.

   Sometimes, mice just die and can't be fixed. If that's the case for you, don't fret. There are plenty of great mice just for Macs that you can snag.

Causes of an Apple Mouse Not Working

When the Magic Mouse loses its Bluetooth connection with the computer or its battery dies, it doesn't function. Here are a few other common reasons why the Magic Mouse malfunctions.

• If the optical sensor is dirty, the cursor may move in a jerky manner.
• If the cursor moves too slowly or too fast, the settings may be the cause.
• A corrupt preference file can cause all sorts of jerky movements.
