I bet I know what it is. This is the place in the code where we use Point3i pt0 = new Point3i() Point3i pt = new Point3i(pt0) I bet it's a Java versioning problem. I bet the Point3i class file we are using does not have the initializer: Point3i(Point3i pt); and in PC versions, Java has that natively, but in the Mac version Java does not.
