Why does my Mac mouse keep disconnecting. How to fix it. Explore common causes and follow simple troubleshooting steps to resolve the issue.
Having a Mac mouse that keeps disconnecting can be frustrating and disrupt your workflow. Constant interruptions can hinder productivity and lead to a less enjoyable computing experience. However, this issue is not uncommon, and understanding the potential reasons behind it can help you find the right solutions.In this article, we will explore the various factors that could be causing your Mac mouse to disconnect frequently. We will also provide practical troubleshooting steps to resolve the issue and optimize the performance of your Mac mouse.

Common Reasons for Mac Mouse Disconnections

Bluetooth Interference

One of the primary reasons for Mac mouse disconnections is Bluetooth interference. When multiple wireless devices share the same frequency band, they can interfere with each other’s signals, leading to connection drops. Additionally, physical barriers or other electronic devices near your Mac can disrupt the Bluetooth signal.

Low Battery

A low battery can be another culprit behind frequent mouse disconnections. If your wireless mouse’s battery level is critically low, it may not maintain a stable connection with your Mac, causing intermittent disconnections.

Software Glitches

Software glitches in macOS can also lead to mouse connectivity issues. These glitches may arise due to system updates, incompatible software, or corrupted settings, resulting in unstable Bluetooth connections.

Outdated Drivers

Using outdated drivers for your Mac mouse can create compatibility problems and cause disconnections. Manufacturers often release driver updates to improve performance and fix bugs, so it’s crucial to keep your drivers up to date.

Hardware Issues

Sometimes, the problem might lie with the mouse’s hardware itself. A faulty or damaged mouse can lead to frequent disconnections, and in such cases, troubleshooting software-related issues may not be effective.

Wireless Range Limitations

The distance between your Mac and wireless mouse can impact the stability of the connection. If you are operating the mouse from too far away or if there are obstructions in the line of sight, disconnections are more likely to occur.

USB Port Problems

For users with a USB-connected mouse, issues with the USB port can cause disconnections. A loose or damaged USB port may not provide a stable connection, leading to intermittent mouse problems.

Troubleshooting Steps

To resolve the Mac mouse disconnection issue, follow these troubleshooting steps:

Check Bluetooth Settings

Ensure that Bluetooth is turned on and functioning correctly on your Mac. Check if the mouse is properly paired with your Mac in the Bluetooth settings.

Replace or Recharge Batteries

If you have a wireless mouse, replace the batteries with fresh ones or recharge the existing ones to ensure sufficient power for a stable connection.

Update macOS and Drivers

Make sure that your macOS and mouse drivers are up to date. Check for available updates and install them to address any compatibility or performance issues.

Reset Bluetooth Module

Resetting the Bluetooth module on your Mac can help resolve connectivity problems. To do this, go to System Preferences > Bluetooth, hold down the Shift and Option keys, and click on the Bluetooth menu. Then, select “Reset the Bluetooth module.”

Check for System Updates

Regularly check for macOS system updates and install them. These updates often include bug fixes and improvements that can help with mouse disconnection problems.

Check Hardware Connections

For USB-connected mice, ensure that the USB port is working correctly. Try connecting the mouse to a different USB port to see if the issue persists.

Use a USB Extension Cable

If you are using a USB receiver for your wireless mouse, consider using a USB extension cable to position the receiver closer to the mouse for a stronger connection.

Optimising Mac Mouse Performance

Apart from troubleshooting, you can take proactive steps to optimize your Mac mouse’s performance and minimize disconnections:

Use a Mousepad

Using a mousepad can provide a smooth surface for your mouse, enhancing its tracking accuracy and reducing the chances of disconnections.

Keep the Mouse and Mac Close

Maintain a reasonable distance between your mouse and Mac to ensure a stable Bluetooth connection.

Minimise Interference

Reduce potential Bluetooth interference by keeping other wireless devices away from your Mac and mouse.

Keep Drivers Updated

Regularly check for driver updates from the manufacturer and keep your mouse drivers up to date.

Regularly Clean the Mouse

Dust and debris can accumulate on the mouse sensor and affect its performance. Regularly clean your mouse to ensure smooth functioning.


Dealing with a Mac mouse that keeps disconnecting can be frustrating, but understanding the potential causes and taking appropriate actions can help resolve the issue. Start by checking for Bluetooth interference and ensuring your mouse has enough power. If the problem persists, follow the troubleshooting steps and optimize your mouse’s performance to minimize disconnections.

Remember, keeping your drivers and macOS up to date is essential for a smooth and seamless computing experience. By implementing these strategies, you can enjoy uninterrupted mouse performance and focus on your tasks without any interruptions.
