This method on UIEvent gets you more touch positions, and I think it's useful for a drawing app, to respond with greater precision to the position of the Pencil stylus.
Is there a similar thing in macOS, for mouse or tablet events? I found this property mouseCoalescingEnabled, but the docs there don't describe how to get the extra events.
I may miss something in your question.
Can't you use the info in allTouches() ?

I have the same question. If you upgrade to the latest version 26.2, you will find that the coalescing of mouse movement events has become more restrictive—they are downsampled to match the screen refresh rate. This has become similar to how the system handles touch events. Unfortunately, regarding this change, I haven’t been able to find any interface provided by Apple that allows access to the original data points before coalescing. It seems that on macOS, the only way for an application to obtain relatively precise and raw mouse movement events is to set isMouseCoalescingEnabled to false. I hope someone can help confirm whether this understanding is correct.
