Question: How to fix choppy scroll with third party mouse on Mac OS?

I'm loving my Mac, but every external mouse I connect, regardless of brand, has this ridiculous choppy effect whenever I use the scroll wheel. I prefer to connect my MacBook to an external display with a keyboard and mouse whenever I'm working from my desk, and this ridiculous problem is driving me crazy and hurting my productivity. I've spent a good amount of time researching this, and I can't find any solutions that make the scrolling "smooth"er than the choppiness of my wired mouse. Is there anything else I can do to fix the problem?

MacBook Pro 13″, macOS 10.15

Hello lawpaw,



Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are unable to use an external mouse with your Mac, as you have an issue with scrolling. To help with this, please follow the relevant steps in these Apple resources, including checking for sources of wireless interference:



If your pointer is jumpy when you use a trackpad, Magic Trackpad, or Magic Mouse

If your Apple wireless mouse, keyboard, or trackpad isn't working with your Mac as expected

Potential sources of Wi-Fi and Bluetooth interference



Cheers!

If your non-Apple mouse is expecting its own vendor driver support, or that of MS Windows support, then its sporadic behavior with Catalina may be the best you can expect. I have several wired mice here with scroll wheels and they are all clunky under macOS.


My primary pointing device is an Apple Magic Mouse 2. The latter has smooth vertical scrolling, and with some optional settings, horizontal scrolling actions to switch between web browser pages.
