2. Check Bluetooth Connection

Wireless mice, such as the Apple Magic Mouse, may experience lag due to interference or connectivity problems with Bluetooth.

It's a good idea to turn off and on your Mac mouse and Bluetooth.

Connecting an external monitor to your MacBook might cause mouse lag, especially if the monitor has a high resolution or refresh rate.

Simply disconnect your external monitor to see if your Mac mouse works properly.

4. Eject Your External Drives

If you're using a USB hub to connect your external drive to your Mac, it may cause your Mac mouse to lag. Try ejecting your external drive to check if your Mac functions properly.

5. Adjust Mouse Settings

Sometimes, adjusting mouse settings can help you resolve the Mac mouse lagging issue.

Here's what to do:

  1. Click the Apple menu and select System Settings.

If none of the above solutions solve your problem, try restarting your Mac.

8. Update macOS

The final and crucial solution for Mac mouse lagging is to update your macOS.

Despite macOS becoming more stable over time, each new macOS release may introduce potential issues that could affect the proper functioning of your mouse. Simply click on System Settings > General > Software Update to check for any available updates.
