macOS Monterey is the latest operating system for Apple computers and comes as an expected update to macOS Big Sur released last year. Monterey is not as vast of an update as the previous version but still represents the latest tech and innovation for an Apple Mac computer. 

One issue that some people are dealing with after making the macOS Monterey upgrade is a mouse or trackpad input that lags. This article will offer some quick fixes to deal with this problem and get your mouse or trackpad running at optimal performance. 

Why am I Experiencing Mouse/Trackpad Input Lags after Installing macOS Monterey?

With every new update comes a range of possible problems. The early versions of each update are typically notorious for having some minor operating issues. 

These will often get ironed out as future updates roll out to fix bugs, but they can annoy anyone who just completed the update and expects their computer to perform flawlessly. 

Fix #1 – Restarting Your Computer

If you run into any weird problems such as lags and latency after installing an update, a simple restart of your system might iron out the problem. This is a good option to start with when you encounter a minor issue and could fix up a lagging mouse and trackpad that occurs after installing macOS Monterey. 

Click on the Apple icon on the top left of your window, and then select Restart from the dropdown menu. You might need to close out of open applications/programs and be sure to save anything you might have running before restarting. 

Fix #2 – Adjust Trackpad Sensitivity

Sometimes the sensitivity settings of the trackpad will get tweaked after performing an update. You can adjust these settings to get your trackpad working again, and it’s good to know how to access these settings if you ever want to make a customized setup.

If your trackpad or mouse icon ever freezes up, this is a good fix for that issue as well. 

To access the trackpad sensitivity settings:

  1. Click on the Apple icon at the top left of your open window 
  2. Click on System Preferences
  3. Select the Trackpad icon
  4. Set the tracking speed to normal for optimal performance and to resolve any issues. 

Fix #3 – Close Problematic Apps

After updating to macOS Monterey, you might run into the issue of apps causing problems with one another when they are open at the same time. This can cause several issues, a laggy mouse/trackpad being one of them. 

By closing out any apps that are open when you experience the issue, you can help identify the source of the problem and get your mouse and trackpad functioning normally again. 

To close problematic apps, you’ll want to quit any programs that are currently running. You can do this by actively closing out the open apps or going into the Force Quit menu to make things go a little faster. 

To access the Force Quit Menu:

  1. Hold down the Command, Option, and Esc keys all at the same time
  2. The Force Quit Menu will appear and display all open apps and programs
  3. Select the apps you want to close and click on Force Quit

Fix #4 – Reinstall macOS Big Sur

macOS Monterey is currently only available in the Beta version, and early versions of any OS typically experience random bugs that take future updates to fix. 

If you have tried all of the fixes above and are still experiencing a laggy mouse/trackpad, you might need to reinstall the previous macOS to get full operation. 

You can also wait until macOS Monterey becomes fully available and has gone through an update or two for increased functionality. This is somewhat annoying but is a good last resort if you need to use your computer and are dealing with the mouse/trackpad issue. 

To reinstall macOS Monterey:

  1. Create a backup of your system before you begin the reinstall process
  2. Restart your computer into recovery mode
  3. Click on Disk Utility once in recovery mode
  4. Select Continue
  5. Click on Erase 
  6. Once macOS Monterey is erased, load a version of macOS Big Sur from the internet or a disk drive.

Final Thoughts

Nobody likes dealing with minor issues, glitches, and problems that appear after a macOS update. Unfortunately, these issues happen, and no software update is ever flawless. Waiting for the full release can sometimes help you avoid this, as the Beta versions often have more problems.  

You need a functional mouse or trackpad to use your MacBook, and the fixes above should help you get a lag figured out quickly. Remember to start with a simple restart and go through the other steps if that doesn’t resolve the issue.
