[SOLVED] Fix Apple Magic Mouse lag issues on Mac

It’s quite annoying to find your mouse is becoming laggy and jumpy when you want to get some serious work done. If you’d like to fix the slow mouse performance issue and get rid of a laggy, jumpy, choppy and even unresponsive mouse, you’ve come to the right place! This post is a comprehensive troubleshooting guide that works on any Bluetooth mouse like the Apple Magic Mouse, Logitech Bluetooth mouses, etc.


Do some basic troubleshooting steps

Before trying anything more complicated, let’s do some basic troubleshooting steps first.

Make sure your mouse is charged

Unlike the wired mouse, the performance of the Bluetooth mouse is affected by its battery status. If your mouse isn’t charged or has worn out batteries, the cursor will be laggy and jumpy.

Clean the bottom surface of your mouse

Make sure the bottom surface (especially the IR light sensor) is clean. A Magic Mouse 2 user reported in Apple Support Communities that if there were pieces of lint or hair in the cavity containing the IR light sensor, the mouse will become laggy.

You can use a soft, dry cloth to clean the railing and remove any debris from the laser opening of the mouse and see if it lags again.

Make sure you’re using the mouse on a flat surface

The mouse may not work properly if you use it on a bedsheet and such uneven surfaces. It’s suggested that you use your mouse on a flat and clean surface.

Turn off your mouse and turn it back on

Most mouses have a power button. You can turn it off, then turn it back on to see the mouse lag issue persists. You can also pull out its replaceable battery and reinsert it.

Unpair and re-pair the mouse

Sometimes the mouse lag issue would be fixed after you re-paired your Bluetooth mouse.

To re-pair the mouse, you need to unpair it first. Here’s how to do it:

  1. Go to System Preferences > Bluetooth and remove your mouse from the Bluetooth devices list.
  2. Re-pair your mouse according to the mouse pairing tutorial.

Restart your Mac

Restarting your Mac often can fix temporary glitches like laggy mouse input and irregular mouse cursor. By restarting your Mac, you’re performing an SMC reset, which may help fix the wireless keyboard / mouse lag issue.

Remove any USB device connected to your Mac

If you have any USB device connected to your Mac and your Bluetooth mouse happens to be laggy and jerky, try removing those USB devices.

According to the white paper “USB 3.0* Radio Frequency Interference Impact on 2.4 GHz Wireless Devices” released Intel in April 2012:

Mouse response in presence of USB 3.0 device

“There is degradation in the performance of the wireless mouse when a USB 3.0 device is connected to the notebook computer. At a distance of 3 feet and greater away from the notebook computer, a significant lag was experienced in the response of the mouse. The impact to mouse performance was found to be the same whether the USB 3.0 peripheral device had data being actively written to it or if it was merely connected to the notebook computer and the link to it established.”

“A similar impact to wireless mouse performance was noted if a USB 3.0 device, such as a flash drive, was used. Since the noise from the USB 3.0 is broadband, it could potentially impact any radio whose antenna is close by. Although the test results are not shown in this paper, similar impact was seen to Bluetooth radio performance.”

Remove any new wireless electronic device nearby

If there are any new wireless electronic device nearby, it may cause interference to your Bluetooth mouse. To rule that out, try keeping any new wireless electronics farther away from your mouse and Mac.

Disable and re-enable Bluetooth on your Mac

Sometimes the Bluetooth mouse lag issue would be resolved after you re-enabled Bluetooth on your Mac. To re-enabled the Bluetooth function on your Mac:

  1. Go to System Preferences > Bluetooth, click Turn Bluetooth Off to disable Bluetooth.
    Turn off Bluetooth on your Mac
  2. Wait for 30s and click turn Bluetooth On to re-enable Bluetooth.

Adjust the tracking speed & scrolling speed

If the tracking speed of your mouse is set to a low volume, the cursor would be lagging or moving slowly. You can follow the steps below to adjust the tracking and scrolling speed of the mouse:

  1. Go to System Preferences > Mouse, under the Point & Click tab, move the slider under Tracking speed to the right to increase its tracking speed. Adjust mouse tracking speed
  2. Go back to System Preferences > Accessibility, on the left sidebar, scroll down to click Point Control, then click Mouse Options… Accessibility Point Control mouse options
  3. Move the slider next Scrolling speed to the right to increase its scrolling speed. Click OK to save the changes.

Disable Handoff Feature

Some Mac users have reported that the Handoff feature would interfere with the wireless mouse, and they fixed the mouse lag issue by disabling the Handoff feature on Mac. If you don’t need the Handoff feature on your Mac, just follow the steps below to disable it and see if this fix the mouse lag issue:

  1. Go to System Preferences > General.
  2. Uncheck the box next to Allow Handoff feature between this Mac and your iCloud devices.
    Uncheck allow Handoff feature between this Mac and your iCloud devices

  1. I think it’s some kind of Mac Bluetooth issue. I tried every last thing on this list and still, BOTH of my Apple mice lag like crazy. Both before and after Ventura. I even bought a Bluthooth dongle to connect to a dedicated antenna.
