Apple Computer Mouse Not Working: Fix Bluetooth Pairing on Mac and Windows

Most Apple mouse connection failures trace to power state, Bluetooth being off, a stale pairing, or the mouse still being bonded to another computer. Work through power, Bluetooth, cable pairing, and interference checks before assuming the mouse is broken. On a Mac running Windows through Boot Camp, expect less reliable Apple accessory behavior and treat re-pairing as a workaround, not a permanent fix.

Start with power and the switch, not the software

Before changing any settings, confirm the mouse is actually on and charged. Apple's guidance for Magic accessories is to slide the power switch off until no green is visible, then back on until green appears. Earlier Apple wireless models use a power button instead: hold it until the green LED turns off, then press again until the LED lights.

If the mouse has replaceable batteries rather than a built-in battery, fresh batteries are the first thing to try. A mouse that never lights up or never becomes discoverable is a hardware or power problem, and no amount of Bluetooth troubleshooting will fix it.

• Slide the switch off (no green), then on (green visible) on Magic Mouse models
• On older models, hold the power button until the LED goes off, then press until it lights
• Replace batteries on models that use them; charge models with built-in batteries
• Confirm the mouse is discoverable before opening Bluetooth settings

Confirm Bluetooth is on and the Mac can see the mouse

On a Mac, open System Settings (or System Preferences) from the Apple menu and click Bluetooth. Make sure Bluetooth is on. If your keyboard works but the pointer does not, Apple documents a keyboard-only route: press Command-Space, type Bluetooth File Exchange in Spotlight, press Return twice to turn Bluetooth on.

If Bluetooth will not turn on at all, restart the computer and try again. That single step separates a stuck Bluetooth service from a mouse problem, and it costs nothing.

• Check Bluetooth status in System Settings before touching the mouse
• Use the Spotlight and Bluetooth File Exchange route if you have no working pointer
• Restart the Mac if Bluetooth refuses to enable
• Note whether other Bluetooth devices still connect; if they do, the fault is likely the mouse pairing

Use a cable to force a fresh pairing

Apple's documented step for Magic accessories that will not connect is to attach the accessory to the Mac with a compatible cable, wait about one minute, then disconnect. Apple states this pairs the accessory with the Mac and charges the built-in battery.

This is the most reliable reset because it bypasses wireless discovery entirely. If the mouse pairs over cable but drops again immediately after unplugging, you have narrowed the problem to the wireless link rather than the mouse itself. Check the charge level afterward through Control Center and Bluetooth.

• Connect the mouse with the cable that matches its port, wait one minute, disconnect
• Check charge level in Control Center, then Bluetooth
• If cable pairing works but wireless does not, focus on interference and range
• Do not assume a USB-C-shaped port implies a particular charging speed or display function

Rule out interference and a second computer

If the mouse connects but will not stay connected, Apple points to wireless interference from other devices as a possible cause. Move the mouse closer to the Mac, remove nearby wireless transmitters from the immediate area, and retest.

A very common cause is that the mouse is still bonded to another Mac nearby. Turn off Bluetooth on that other computer, or unpair the mouse there, then try pairing again on the machine you want to use. A mouse that pairs fine with a second computer is not broken; the original host is the problem.

• Test with the mouse within a short distance of the Mac
• Turn off Bluetooth on any other Mac that previously used the mouse
• Try pairing the mouse with a different computer to isolate mouse versus host
• If it pairs elsewhere, keep the mouse and troubleshoot the original computer

Windows on a Mac through Boot Camp: expect limits

If you run Windows on an Intel Mac using Boot Camp, Apple mouse behavior can be inconsistent. Users in a Microsoft community thread described Magic Mouse and keyboard disconnecting after a couple of days in Windows 10, with the accepted workaround being to unpair the accessories in macOS, reboot into Windows, and pair them again there. One user reported that after unpairing in macOS and removing the devices in Windows settings, then power-cycling the mouse and keyboard, both paired and worked.

Treat that as a workaround, not a repair. Other users in the same thread reported the mouse would not pair at all after a macOS security update, and one reported that scrolling stopped working after a Windows update while other functions continued. Apple's own accessory guidance is written for macOS, so Boot Camp users should not expect the same reliability.

• Unpair the mouse in macOS Bluetooth settings, then reboot into Windows
• In Windows, remove the mouse under Bluetooth and other devices, then power-cycle and re-pair
• Expect to repeat this after some macOS or Windows updates
• Keep a wired USB mouse available so you can navigate if the Apple mouse drops

Windows on a non-Apple PC: pairing basics

For an Apple mouse used with a Windows PC, the sequence is ordinary Bluetooth pairing. Charge or install batteries, turn the mouse off and on, and make sure it is not still connected to a nearby Mac. In Windows 11, open Settings, Bluetooth and devices, turn Bluetooth on, choose Add device, then Bluetooth, and select the mouse. In Windows 10, use Settings, Devices, Bluetooth and other devices, then Add Bluetooth or other device.

If the mouse appears but will not connect, remove the device in Bluetooth settings, power-cycle the mouse, and add it again. If Bluetooth is missing entirely or no devices appear, run the Bluetooth troubleshooter and check Windows Update. For a PC, get any Bluetooth driver from the PC manufacturer's support site for your exact model rather than an unverified download.

• Remove the stale device entry, then re-add the mouse
• Toggle the PC's Bluetooth off, wait, and turn it back on
• Run the Windows Bluetooth troubleshooter if no devices appear
• If every Bluetooth device fails, the PC's Bluetooth hardware or driver is the suspect, not the mouse

When to stop troubleshooting and what to buy

Buy a replacement only when a diagnostic result points that way. If the mouse never lights up with fresh batteries or a full charge, if it will not pair with any computer you try, or if a cable pairing fails on a Mac that pairs other accessories, the mouse is the likely fault. If the mouse pairs and works on another computer, keep it and address the host instead.

If the problem is confined to Windows on a Mac through Boot Camp, a replacement Apple mouse may behave the same way. A wired USB mouse is the low-risk fallback for that setup, and it also gives you a pointer for future troubleshooting. Before any repair that involves reinstalling an operating system or reformatting a drive, back up your data, and contact IT support first if the machine is managed by an employer or school. Do not disable security features or install drivers from unofficial sources to force a connection.

• Replace the mouse if it fails to power on, fails to pair anywhere, or fails cable pairing
• Keep the mouse if it works on another computer; fix the host instead
• On Boot Camp, prefer a wired fallback over buying another wireless Apple mouse
• Back up before OS-level repairs; involve IT support on managed devices
