Hi kidfromkrypton,
The pointer does autohide as soon as the show begins, but anymovement of the pointing device causes it to reappear. If you leave the pointing device unmoved for 3 seconds the pointer hides again on Mac according to this article.
Regarding to your requirement set by default hide pointer during presentation on MAC, we are sorry for this feature limitation.
