How to Resolve Magic Mouse Issues on a Mac Computer
Fixing the Problem of Slow Mouse Movement on Magic Mouse
There are two common reasons for the Magic Mouse's slow mouse movement or sudden stops. The first reason could be that the mouse is running out of battery. When the battery is low, you may experience the mouse jittering, lagging, and losing Bluetooth connection with the Mac.
To fix this issue, check the Magic Mouse battery. Turn the Magic Mouse upside down and check if the green LED light is blinking; that's a sign of loose battery connection. Simply reinsert the battery to resolve the problem.
Magic Mouse 2 eliminates issues related to battery polarity. When Apple updated the Magic Mouse, they replaced the standard AA battery with a non-removable rechargeable battery pack. Since the redesign, connectivity problems with the Magic Mouse have significantly decreased.
Dust Buildup
Another potential culprit causing improper functioning of the Magic Mouse could be dust accumulating on the optical sensor of the mouse.
A simple way to resolve this issue is to clean the mouse's sensor. No need to relocate or disassemble any parts of the mouse. Just use a keyboard cleaning tool to suction out the dust lodged in the sensor hole.
Additionally, take a moment to clean your mouse pad or the surface where you place your Magic Mouse. Despite using optical sensor technology, Magic Mouse can still accumulate debris, potentially hindering its precise operation.
Magic Mouse Configuration File Error
While Magic Mouse issues may stem from hardware problems, another possible cause could be a corrupted or faulty preference file that Mac uses to configure Magic Mouse during the initial setup.
Certain preference files might be the culprit behind inaccurate Magic Mouse behavior. If you notice any abnormal mouse behavior, try deleting each file one by one and check, or alternatively, delete all those files to let Mac recreate them and fix Magic Mouse issues on your Mac computer.
Here is a list of files you can consider deleting:
com.apple.AppleMultitouchMouse.plist (Magic Mouse)
com.apple.driver.AppleBluetoothMultitouch.mouse.plist (Magic Mouse)
com.apple.driver.AppleHIDMouse.plist (Wired Apple Mouse)
com.apple.AppleMultitouchTrackpad.plist (Trackpad)
com.apple.driver.AppleBluetoothMultitouch.trackpad.plist (Magic Trackpad)
All these files are located in the Library folder, specifically ~/Library/Preferences/. By default, in OS X and macOS versions since OS X Lion, the Library folder, along with its files and folders, is set to be hidden. To access this hidden folder, you first need to enable the visibility of the Library folder.
Next, delete various preference files on your Mac. Generally, deleting preference files doesn't impact the system, unless you reset these files to their original default state. However, the optimal solution is to back up your Mac before deleting these files to avoid any adverse situations, then follow the steps below:
First, enable the display of the Library folder, then open the Preferences folder within the Library. In the Preferences folder, you'll find the listed preference files as mentioned above.
If encountering issues with the Magic Mouse, try dragging the 2 Magic Mouse files into the trash to delete. Similarly, if the trackpad is causing errors, attempt to drag the 2 files related to the trackpad or the 2 Magic Trackpad files into the trash to delete.
Lastly, if the Wired Apple Mouse is malfunctioning, try dragging the remaining file into the trash to delete.
After deleting the preference files, restart your Mac. Upon completion of the restart, your Mac will rediscover the connected mouse or trackpad, search for preference files to reload, and recreate default preference files for the cursor.
By utilizing the new preference files, mouse or trackpad issues will be resolved. However, you'll need to return to System Preferences and reconfigure the Mouse or Trackpad to your preferences since these devices will be reset to their original default state.
