Nothing can be more annoying than a slow and lagging mouse, especially when you are inspired to try out something new or working under pressure to meet a deadline.
The issue of a slow and lagging mouse on Mac could be due to a variety of reasons, ranging from weak batteries, faulty mouse and incorrect mouse settings to software related issues.
Fix Slow and Lagging Mouse on Mac
In most cases, the problem of slow or lagging mouse on Mac can be fixed by using the following troubleshooting steps.

Another common reason for the mouse not working properly is due to the USB Port on your Mac not playing well with the Mouse due to a technical glitch or a problem with the USB port.
To rule out this possibility, plug the Mouse into another USB Port and see if it starts working better. If you are using a USB Hub, remove the Mouse from USB Hub and plug it directly into the USB Port.
