The issue of a laggy or slow mouse on Mac could be due to a variety of reasons, ranging from weak batteries, a faulty mouse and incorrect settings to software related issues.
Hence, we are listing below a number of ways to fix laggy or slow mouse on Mac, starting with the simplest methods like replacing the batteries on the Mouse, before moving onto more complex methods.
You can try these methods in sequence or jump to any particular method/methods that you believe are more likely to help in your case.
Check Mouse and Mouse Pad
Examine your Mouse and make sure that no debris/dirt is stuck in the laser opening of the Mouse, located at the bottom of the Mouse. Also, take a good look at the Mouse Pad and see if it needs to be replaced (Worn out, Dirty).
One of the most common reason for laggy or slow Mouse on Mac is due to the Batteries on the Mouse being weak. Hence, simply replace the battery on the Mouse of your Mac with a new one and see if it helps in fixing the problem
Change USB Port
Another common reason is the USB port of the Mac not playing well with your Plug & Play Mouse due to some technical glitch. To rule out this possibility, plug the mouse into another USB port and see if it starts working better.
In case you are using a USB Hub, try plugging the mouse directly into the USB Port of your Mac and see if the problem is gone.
The most common troubleshooting tip is to restart your device and see if it starts working properly after restarting. This simple tip is based on the fact that restarting a computer can often help it recover from stuck programs and minor software glitches which might be causing problem s on the device.
1. Click on Apple Logo from the top menu bar on your Mac and then click on Restart from the dropdown menu.
Is Your Mouse Defective ?
Follow the steps below, to rule the possibility of the Mouse being defective.
1. Plug in another Wireless/Bluetooth Mouse into your Mac.
If the new mouse works perfectly fine than chances are that your mouse is defective and needs to be replaced.
2. Now, plug the Mouse into another computer (Preferably a Windows computer).
If the Mouse is still not working, it confirms that the Mouse is defective. If you recently bought the mouse, return or exchange it as soon as possible.
Fix Slow Mouse On Mac Using System Preferences
In case you find that the cursor is dragging or moving slowly, it is most likely that the tracking speed of the mouse has been set to a low value on your Mac.
1. Click on the Apple Icon from the top left corner of your screen and then click on System Preferences… in the dropdown menu.
2. On the System Preferences screen, click on the Mouse icon (See image below)
3. On the next screen, adjust both the tracking speed and scrolling speed by moving their respective sliders to the right (See image below)
The change takes effect immediately, start using your Mouse and see if it feels faster than it was before. In case the Mouse has become too fast, play around with the sliders, until you get the right tracking speed.

Some users have reported that turning off the handoff feature on Mac has resolved the problem of a slow or laggy mouse.
1. Click on the Apple icon from the top left corner of your screen and then click on System Preferences… in the dropdown menu.
2. On the System Preferences screen, click on General.
3. On the General settings screen, uncheck the option for Allow handoff between this Mac and your iCloud devices.

1. Disconnect all the wireless devices (including your mouse) from your Mac.
2. Next, Turn OFF the Bluetooth option on your Mac

4. Now, plug the Mouse back into the Mac and enable Bluetooth on your Mac.
