On all other graphic programs, this mouse is brilliant. The scroll facility lets you pan the image rather than zoom. I've had to revert to the earlier mighty mouse which stops the unexpected zooming. But the scroll ball should still have the option of panning image. My tablet has touch which does pinch zoom and rotate.
The original magic mouse came out at about 2009. So in the intervening decade before the release of painter 2019 Corel just let this pass them by? Not good Corel. Keep up.
they were allegedly working on native mac os touch gestures since painter 12, I don't even bother checking if they finally managed to collaborate with anymore.
