I had a Zinc project which worked fine on PC but showed absolutely nothing on Mac. I just got a nice Window with nothing in it. Even a swf with a simple button wouldn’t load on Mac.

After an hour of searching I saw that in a Mac Zinc Project, you can choose the Embedded Flash Control in the Flash Settings tab. If you want your executable to work on Mac, you better set this on Flash 9…

Yeah, life can be hard.
