Hi all,
recently my macbook pro mouse pointer (I use a trackpad) started acting weird. It randomly jumps every 30-60s sometimes even more frequently.
Tried choosing Ignore your trackpad option in accessibility settings, restarting Mac in Safe Mode, reconfiguring SMC, NVRAM, and PRAM, got so desperate that I even wiped hard disk and reinstalled OS - Catalina. And it's still the same.
I'm using Avast security and it did find and cleaned some infected files before reinstalling OS (it was something related to Parallels Desktop). I've scanned my mac after reinstalling OS as well. Multiple times, using different applications - all good.
One thing I noticed, it seems to work fine when I turn the WiFi off.

Any ideas?

Hello and welcome.

-Which exact model MacBook Pro?
-Any liquid damage that you are aware of?
-Any keys on the keyboard not working properly, especially around the trackpad area?

Most of the time, that issue is related to a hardware issue because of liquid damage in or around the trackpad area.
