It’s the fidget spinner among mice. I use it mostly when working on windows where the Magic Trackpad isn’t really an option

There's a non-Apple driver for the trackpad that works reasonably well.

Do you happen to know what it's called? I was looking for this yesterday and couldn't find a good one with what I was Googling.

I pay $13/year for this: https://magicutilities.net/ They have a 30 day trial so you can test it out.

I tried the open source drivers on my MS Surface but I never got them to work.

Same one mentioned in the other reply. It has an annoying subscription and bind-to-device thing. On the other hand, it's cheap and it works.
