This article will explain what to do if your wireless Bluetooth mice lags on your Mac running macOS BIG SUR.
A slow or laggy mouse is the worst thing, especially when you’re trying to do serious work. Below are the steps for troubleshooting and fixing a slow, unresponsive or laggy MacOS Big Sur mouse.
Mac Big Sur: Fix Slow or Laggy Mouse
A Mac’s slow or laggy mouse could be caused by a number of factors, including weak batteries, incorrect settings, and faulty mice.
These are some ways to fix a slow or laggy mouse on Mac. We’ll start with the most basic methods and then move on to more complicated solutions.
First, try these steps
- If your Mac Big Sur mouse is slowing down, ensure that it’s charged. You should check the batteries to make sure they are working properly. Some Magic Mouse models, for example, may come with rechargeable batteries. The Bluetooth icon can be clicked in the menu bar of your Mac to check the battery level. Connect to your Mac, or use a Lightning-to-USB Cable to charge your mouse if the battery level is low.
- Switch off your mouse and turn it on again. Use the power button on your mouse to turn it off. Wait a few seconds, then turn it back on. The Magic Mouse, for example, has a power switch located on its underside. Remove the removable battery from your mouse, and wait for it to cool down before you insert it again.
- Restart your Mac. This can be done by going to the Apple menu > Restart.
- You may notice that your mouse is not moving fast enough to keep up with your mouse’s movements. This could be due to a slow mouse pointer. Next, adjust the tracking speed.
- Make sure your Mac runs the most recent version of macOS software. Go to System Preferences > Software update.
- Clean your mouse. Clean your mouse by turning off the power or removing the battery. Next, wipe the mouse’s body with a microfiber cloth.
- Reset the SMC on your Mac. Refer to Apple’s documentation
Moderation that is safe
To see if it helps, restart your Mac in Safe Mode. Here’s how to do it:
To determine if your Mac is Intel-based or with Apple silicon, go to the Apple menu > about this Mac. These are the steps to follow after you have determined.
Turn off your Mac. Wait for it to turn off completely. Then, press the Shift key immediately.
Continue holding down the Shift key until the login window appears. Next, log in.
Your Mac should be turned off.
Hold the power button down to turn on your Mac. Continue holding the power button down until you see the Startup Options window.
Select your startup disk, hold down the Shift key, and then click “Continue In Safe Mode.”
Safe Mode will test your problem with the mouse. Next, exit Safe Mode by simply restarting the Mac. Then you can test again.
Reset your Mac’s Bluetooth Module
This will resolve the problem. You will lose all your Bluetooth connections during this process. You can still turn on Bluetooth on your Mac using your trackpad, keyboard, mouse or mouse if necessary. Here’s how it works:
Hold the Option + Shift keys on your keyboard together by pressing and holding them simultaneously.
Press the keys while holding down the buttons. Click the Bluetooth icon at the top-right corner in your Mac’s menu bar.
Next, click on the Reset Bluetooth module option. Follow the onscreen instructions.
You can also factory reset all Apple devices if this fails. This will reset any Apple Bluetooth accessories, such as a Magic Mouse, to their default settings. It may solve your problem.
You can delete preference files
You can delete your mouse’s preference file (.plist) files. This could resolve your problem. This is how it works:
Your Library folder can be opened. To do this, go to Finder >Go > Go to Folder. This will open a dialog. Then, enter:
Click on the Preferences folder. These files are also available:
Drag these files to the Desktop.
Restart your Mac.
Make sure you test your mouse. If the problem persists, you can restore the files you have moved to your desktop. These files can be deleted if it is resolved.
