Mouse stops functioning properly when multitasking

When multitasking on my 2021 iMac, I am finding that every so often my mouth stops functioning properly and it won't let me click on anything until I go through and I do a force quit on a bunch of stuff that's not running anymore

iMac 24″, macOS 15.1

This computer is an Apple Silicon computer that needs an external mouse


What brand of mouse is being used and how it the mouse connected to the computer


Having to Force Quit Applications to get the mouse to function is usually an indicator of Heavy Usage


Use the Activity Monitor application and make sure to use View >> View All Processes 


What process or processes are using the Most CPU  and Memory.


Often times,  the issue maybe a combination of Processes


When the computer is using so much CPU / Memory,  it can also be an indicator of a Lack Of Empty Space on the Drive.


In which case, the CPU and Memory usage would become much more because it is searching for Empty Space to save all the Changes the user is performing.


How many Web Browser tabs are in usage.


Each tab may have content that is consuming great amounts of CPU / Memory .

I too am using 2 different Apple Magic Mice


One on a M2 machine and another on a M4 Machine


The Mice just work and work, just fine

To avoid a session of Q&A, Q&A  and Q&A  


Download the Application Etrecheck ( External Link ) directly from the Developer.


The Application is Not a " Silver Bullet " it is only a tool to examine the Hardware / Software used on this computer 


This is a Diagnostic Tool that makes no changes to the computer.


It makes a coherent and readable inventory of both the Hardware and Software used on the computer 


The application is free or paid for added features.
