Am experiencing some very frustrating mouse issues with my Mac desktop (running Catalina v10.15.3 with 3.4 Ghz Quad-Core Intel i5, Radeon Pro 5470 4GB graphics).

I am experiencing:
  • Jumping cursor
  • Inconsistent scrolling
  • Delayed click response
  • Needing to click 2 or 3 times on a single-click icon / function
They symptoms are presented in any configuration:

  • Apple bluetooth mouse
  • Apple connected mouse
  • Logitech wireless mouse
  • Logitech connected mouse
For each of the connected options, I have used various available USB ports for the wireless fob transceivers.

Any ideas what the issue might be?

Thanks in advance.

Same work area configuration? I've encountered weird things happening with an optical mouse on a highly reflective surface (i.e. glossy tabletop).

Clean the mouse - dust / dust might be causing this. It happens with us due to cat fur daily.

But didn't he use four different ones? Seems odd that all of them would be dirty at the same time.

Did this all start with the install of Catalina? or before? I assume SoxJox has already searched Apple for a possible fix?

Oh, sorry, I misinterpreted.

Weird issue.

I don't correlate mouse issues with upgrade to Catalina, but who knows? Stranger and unexpected 2nd and 3rd order effects are not unknown.

Edit; Although, at lars10 suggestion, am working my way through Apple network MacOS Catalina problem reports, which seem extensive. No immediate solutions present.

I've been in computers for almost 35 years now and random jumping mice are one of the hardest problems to diagnose. Can be video-related, OS-related or anything really. I just had a personal machine having a stuttering mouse issue which ended up being related to a slowly-overheating cpu (an internal cable was slowing down the CPU fan). Last year I had it when by monitor spanning software (Synergy) got all out of whack after an update. A few years prior it was video card drivers. It takes *forever* to isolate in some instances.

I had a jumping mouse (tried 3 and they all did it) on a Pixelbook but only when using it through a dock to an external monitor. Thought it was the remote desktop software lagging, or the GPU not keeping up.

Turns out there is a PIxelbook bug where mice on external monitors are jumpy unless you turn on the "night light" mode. So I have that enabled with the color temp set to the coolest setting, and my mouse works great. So random.

That's why my first thought went to the Catalina OS upgrade. It has been notoriously problematic, especially on upgraded machines. If it is possible to downgrade your OS, that might be worth considering. Mojave has been far more stable. There isn't a whole lot in Catalina that is essential. Or, if you need Catalina and cannot cope with the mouse problem any longer, another more drastic action is to save all your work, wipe your hard drive, and do a clean install of everything.

Agreed. The overheating issue is in fact something that Catalina is known to cause more frequently than its predecessors. This particular OS is far too busy and requires constant cooling, whether it's a desktop or laptop computer. Collateral problems in peripherals would not surprise me.
