Magic Mouse Not Working on Mac? Fix Connection, Scrolling, and Tracking

A Magic Mouse problem can look deceptively simple: the cursor won’t move, scrolling suddenly stops, or tracking becomes erratic.

But these symptoms don’t necessarily have the same cause.

Before changing random settings, I find it more useful to identify what part of the mouse experience has actually failed — the connection, clicking and scrolling, or cursor tracking. That makes troubleshooting faster and avoids unnecessary fixes.

This guide is for Mac users whose Apple Magic Mouse is not working properly.

First, identify what your mouse is actually doing

“Magic Mouse not working” can mean several different things.

For example:

• The mouse won’t connect to your Mac at all.
• The cursor doesn’t move after the mouse connects.
• Right-click doesn’t work.
• Scrolling stops or behaves unpredictably.
• The cursor freezes, jumps, or tracks poorly.
• The problem started after a macOS update.

These symptoms point to different parts of the system. I would troubleshoot them in this order: power → connection → macOS settings → sensor and tracking → software conflicts.

If your Magic Mouse won’t connect or respond

Start with the physical and Bluetooth connection. There’s no reason to reset mouse preferences if the Mac isn’t reliably communicating with the mouse in the first place.

1. Turn the mouse off and back on

Switch the Magic Mouse off, wait a few seconds, and turn it back on.

Then check whether the mouse is powered on and whether your Mac detects it.

This simple step can resolve a temporary connection state without removing the pairing.

2. Check the battery or recharge the mouse

A low battery can cause a wireless mouse to disconnect, respond intermittently, or stop working.

If your model has a rechargeable battery, connect it to power and let it charge before testing it again.

If you’re using an older Apple mouse with replaceable batteries, check their condition and replace them if necessary.

Don’t assume that the mouse has enough power simply because it worked earlier. Wireless peripherals can behave inconsistently before they stop working completely.

3. Turn Bluetooth off and back on

If the mouse has power but your Mac can’t connect to it, reset the Bluetooth connection before taking more drastic steps.

Go to:

Apple menu → System Settings → Bluetooth

Turn Bluetooth off, wait a few seconds, and turn it back on.

On older versions of macOS, you’ll find Bluetooth under System Preferences.

Then check whether the Magic Mouse reconnects.

4. Forget the mouse and pair it again

If Bluetooth is working but the pairing itself appears to be the problem, remove the mouse from your Mac and pair it again.

Go to your Bluetooth settings, locate the mouse, disconnect or forget it, and then reconnect it following the on-screen instructions.

This is more useful when the mouse appears in Bluetooth settings but repeatedly fails to connect or respond.

What about a mouse with a USB receiver?

Not every wireless mouse connects through Bluetooth.

If you’re using a third-party wireless mouse with a USB receiver:

• Unplug the receiver and reconnect it.
• Try another USB port.
• Avoid connecting it through a problematic hub.
• Test the receiver directly on the Mac if possible.

If the mouse works when connected directly but not through a hub, the mouse itself may not be the problem.

If your Magic Mouse connects but scrolling or clicking doesn’t work

A successful Bluetooth connection only confirms that the Mac can see the mouse. It doesn’t guarantee that every gesture and click setting is configured correctly.

5. Check your mouse settings

Open:

Apple menu → System Settings → Mouse

Then review settings such as:

• Tracking speed
• Scrolling behavior
• Secondary click

If right-click isn’t working, check whether Secondary Click is enabled.

If scrolling feels unusually slow, fast, or inconsistent, review the relevant mouse settings before assuming there’s a hardware problem.

The exact settings and labels vary between macOS versions.

6. Restart your Mac before resetting preferences

If the mouse was working normally and suddenly started behaving strangely, restart the Mac first.

A restart can clear temporary issues affecting Bluetooth, input services, or macOS settings.

I would do this before manually deleting configuration files. Restarting is reversible and much less disruptive.

7. Reset mouse preference files only as a later step

Corrupted preference files can sometimes cause input settings to behave incorrectly. However, deleting .plist files shouldn't be the first response to every Magic Mouse problem.

If you’ve ruled out power, connection, and basic settings, you can consider resetting the relevant mouse preferences.

Before deleting anything, make a backup of the file so you can restore it if necessary.

Mouse preference files are typically stored in:

~/Library/Preferences

After resetting the relevant preferences, restart your Mac and check whether macOS recreates the configuration correctly.

An important limitation

I wouldn’t recommend blindly deleting every .plist file containing the word "mouse." Preference files vary across macOS versions, and an article should identify the exact file it expects the user to modify.

If you don’t know which file is responsible for the issue, restarting and checking your settings is safer than randomly deleting configuration files.

If the cursor moves but tracks poorly

Poor tracking is a different problem from a failed Bluetooth connection.

If the cursor jumps, freezes, moves inconsistently, or doesn’t follow your hand accurately, check the physical tracking conditions first.

8. Clean the tracking sensor

Inspect the bottom of the mouse for dust, lint, or other debris around the tracking sensor.

Gently remove visible debris and test the mouse again.

Also try the mouse on another suitable surface. Some surfaces can make optical tracking less reliable.

If cleaning the sensor immediately improves cursor movement, you’ve identified a physical cause rather than a macOS configuration problem.

9. Adjust the tracking speed

Sometimes the mouse is technically working, but the cursor simply feels wrong.

Go to:

Apple menu → System Settings → Mouse

Adjust Tracking Speed and test the cursor again.

This won’t fix hardware tracking failures, but it can resolve situations where the cursor appears unusually slow or fast because the setting was changed.

If the problem started after installing an app or update

Timing can be useful evidence.

If your mouse started behaving differently immediately after installing software, updating macOS, or changing system settings, start with what changed rather than applying every possible fix.

10. Check for third-party software conflicts

Some apps can modify mouse behavior, gestures, scrolling, or pointer acceleration.

If the issue began after installing such software, temporarily quit or uninstall it and test the mouse again.

This is more relevant to mouse utilities, customization tools, input managers, and other software designed to interact with pointing devices.

I wouldn’t assume that every recently installed third-party app is malicious. The more useful question is whether the app actually has a reason to interact with your mouse or system input.

11. Update macOS

If the problem began after a macOS update, or you suspect a system-level bug, check for a newer software update.

Go to:

Apple menu → System Settings → General → Software Update

On older versions of macOS:

Apple menu → System Preferences → Software Update

Install available updates and test the mouse again.

An update can fix software issues, but it isn’t automatically the right answer to a connection or hardware problem. That’s why I would check the symptom first.

My troubleshooting framework: follow the failed function

The biggest mistake I see in general troubleshooting lists is treating every “mouse not working” problem as identical.

I use this sequence instead:

What failed?Check firstThen tryMouse won’t power onBattery or chargingTest after charging or replacing batteriesMouse won’t connectBluetooth or USB receiverReconnect or pair againConnected but doesn’t respond correctlyMouse settingsRestart, then investigate preferencesRight-click or scrolling failsSecondary Click and mouse settingsCheck for software conflictsCursor jumps or tracks poorlySensor and surfaceAdjust tracking settingsProblem began after a changeRecently changed software or macOSRemove the conflict or update the system

The principle is simple: don’t reset something that hasn’t failed.

If Bluetooth works, start with the mouse function that’s actually broken. If tracking is the problem, inspect the sensor before rebuilding your Bluetooth connection. If the mouse won’t even connect, don’t spend time adjusting scrolling speed.

When to suspect a hardware problem

Software troubleshooting has limits.

You should start considering a hardware issue if:

• The mouse won’t work with another compatible Mac or device.
• It repeatedly disconnects despite having sufficient power.
• The sensor remains unresponsive after cleaning and testing different surfaces.
• The problem persists after ruling out Bluetooth, settings, and software conflicts.

Testing the mouse with another compatible device is particularly useful because it helps separate a Mac-specific problem from a mouse-specific one.

If the mouse fails everywhere, changing more settings on your Mac is unlikely to help.

Final takeaway

The fastest way to fix a Magic Mouse isn’t to work through a long list of random solutions.

First identify whether you’re dealing with a power problem, connection problem, mouse setting, tracking issue, software conflict, or possible hardware failure.

That diagnosis determines what to try next.

If your Magic Mouse is still not working, note the exact symptom — such as “connected but not scrolling” or “cursor jumps but clicking works” — along with your macOS version. The more specific the symptom, the easier it is to avoid unnecessary troubleshooting.

Experience-Based Takeaways

1. Diagnose the symptom before choosing the fix

“Not working” is too broad to be useful. Break the problem into connection, clicking, scrolling, and tracking.

2. Start with reversible fixes

Power checks, reconnection, settings, and restarting should come before deleting preference files or making deeper system changes.

3. Use timing as evidence

If the issue appeared immediately after installing an input utility or updating macOS, investigate that change instead of treating the timing as irrelevant.

4. Know when to stop troubleshooting software

Testing the mouse on another compatible device can prevent hours of unnecessary macOS troubleshooting when the hardware itself is failing.
