TBH i like the circle apple uses on its mouse integration. It can be a hollowed out circle to differentiate it a bit. And maybe it needs a different graphic when the mouse button is pressed. You’ll also need something that indicated that you have a pulley menu you can pull when the cursor enters that area.
It is going to need a fitting (visualy) text cursor for text areas.
Hmmm. I cant think any other case where it needs a different cursor at the moment.
