What Causes a Mouse to Lag on a Mac?

Table of Contents

There can be several potential causes of a lagging mouse on a Mac. Understanding the root cause of the problem is the first step in troubleshooting the issue. Here are some of the most common reasons why a mouse might lag on a Mac:

Outdated software: One of the most common reasons for a lagging mouse on a Mac is outdated software. If your Mac’s operating system or any of the drivers that control your mouse are not up to date, it can cause your mouse to lag. This issue can usually be resolved by checking for and installing software updates.

High CPU usage: If your Mac is running multiple applications simultaneously or has many background processes running, it can lead to high CPU usage, which can cause your mouse to lag. This issue can often be resolved by closing unnecessary applications or performing a system restart.

Hardware issues: A lagging mouse can also be caused by hardware issues. If your mouse is damaged, has a low battery, or is experiencing connectivity issues, it can cause lagging or freezing. In such cases, try replacing the battery or connecting the mouse to another USB port to check if the issue is resolved.

Corrupted preference files: Preferences files are files that contain specific settings for applications on your Mac. If these files become corrupted, it can cause a range of issues, including a lagging mouse. You can fix this issue by deleting the preference files associated with your mouse or performing a system-wide preference file reset.

Malware or viruses: Malware or viruses can infect your Mac and cause your mouse to lag. In such cases, run a virus scan using a reputable anti-malware software to identify and remove any malicious software.

Hardware limitations: Older Macs or those with lower hardware specifications may struggle to keep up with newer software or applications, leading to a lagging mouse. If you have an older Mac, consider upgrading your hardware, such as your processor or RAM, to improve performance.

8 Ways to Fix Lagging Mouse on Mac OS

Fix 1 — Turn off and on Bluetooth

Sometimes the Bluetooth connection between the mouse and the Mac can become unstable, causing the mouse to lag or freeze. One solution to this issue is to turn your Bluetooth on and off. Here’s how it works:

The first step in the process is to turn off your Mac’s Bluetooth. You can do this by clicking on the Bluetooth icon in the menu bar at the top of your screen and selecting “Turn Bluetooth Off” from the drop-down menu. Alternatively, you can go to System Preferences > Bluetooth and click on “Turn Bluetooth Off.”

After turning off Bluetooth, wait for a few seconds to ensure that the Bluetooth connection between your Mac and the mouse is completely disconnected.

Once you’ve waited for a few seconds, turn Bluetooth back on. You can do this by clicking on the Bluetooth icon in the menu bar and selecting “Turn Bluetooth On” from the drop-down menu. Alternatively, you can go to System Preferences > Bluetooth and click on “Turn Bluetooth On.”

Once you have turned Bluetooth back on, you will need to reconnect your mouse to your Mac. This process varies depending on the type of mouse you are using. In general, you will need to put your mouse into pairing mode and then select it from the list of available devices in the Bluetooth menu. Consult your mouse’s user manual for specific instructions on how to put it into pairing mode.

Once you have reconnected your mouse, test it to ensure that it is working correctly. Move the cursor around your screen and test all of the mouse’s buttons to ensure that they are responsive and not lagging or freezing.

By turning your Mac’s Bluetooth on and off, you are essentially resetting the Bluetooth connection between your Mac and the mouse. This can help to resolve any issues with the connection, resulting in a more stable and responsive mouse.

However, it is worth noting that this may not always be a permanent fix, and you may need to repeat this process if you continue to experience issues with your mouse lagging or freezing.

Fix 2 — Use your Mouse on a Flat Surface

Most computer mice, including those designed for Macs, are designed to work best on smooth and flat surfaces. This is because the sensor in the mouse needs to be able to accurately track the movement of the mouse across the surface in order to function properly.

When you use a mouse on an uneven surface, such as a fabric or textured surface, the sensor can become confused and may not be able to accurately track your movements. This can result in the cursor on your screen jumping or skipping around, making it difficult to use the mouse effectively.

To fix this issue, try using a mousepad or a flat surface that is smooth and even. This will provide a consistent surface for the mouse to track on and should help to eliminate any tracking issues you may be experiencing.

Alternatively, you could consider purchasing a mouse that is designed to work on uneven surfaces, such as a trackball or a gaming mouse with adjustable DPI settings. These types of mice are designed to provide accurate tracking on a variety of surfaces, including uneven ones.

Fix 3 — Change the USB Port

If you’re experiencing mouse lagging issues on your Mac, changing the USB port that your mouse is connected to can sometimes help to resolve the issue. Here’s why:

USB ports can sometimes become overloaded or have connectivity issues, which can cause devices such as mice to experience lag or other performance issues.

By switching the USB port that your mouse is connected to, you can potentially resolve any connectivity issues or overloading problems that may be causing the lag.

Additionally, some USB ports on Macs are more powerful than others, and using a more powerful port may provide better performance for your mouse.

For example, USB 3.0 ports are generally faster than USB 2.0 ports, so if your Mac has both types of ports, it’s worth trying to switch to a USB 3.0 port to see if it helps to improve mouse performance.

To switch the USB port that your mouse is connected to on a Mac, simply unplug the mouse from the current port and plug it into a different one. Your Mac should automatically recognize the new connection and start using the mouse again.

If the lagging issue persists, you may want to try other troubleshooting steps, such as resetting the SMC or PRAM on your Mac, or updating the mouse drivers if applicable.

Fix 4 — Turn off the Handoff feature

Some users have claimed that removing the Handoff option on Mac solved the problem.

The Handoff feature on a Mac allows you to start a task on one device and continue it on another. For example, you could start composing an email on your Mac and then pick up where you left off on your iPhone or iPad.

This feature uses Bluetooth Low Energy (BLE) technology to establish a connection between devices and transfer data seamlessly.

By turning off the Handoff feature, you can potentially reduce the amount of wireless interference on your Mac and improve the performance of your mouse.

To turn off Handoff on a Mac, follow these steps:

Click on the Apple menu in the top left corner of the screen.
Select “System Preferences” from the drop-down menu.
Click on “General” in the System Preferences window.
