Why do I need a driver to enable multiple points of touch for my Mac and Avocor?
Mac devices currently do not feature support for touch screens with multiple points of touch. You will only get up to one point of touch without a third party driver in place.
Luckily we have an answer to that. The driver, linked below, will unlock your Mac + Avocor experience.
