I'm trying to build an install package using PackageMaker. Our software is created on a Windows machine and distributed to both Macs and Windows OS. For Mac, we currently use a .zip file because that's the best we can seem to do. I'm trying to use PackageMaker to build and installer (which I got started). What I don't understand is if the user has to have PackageMaker on his MAC for this to work? Does it build a stand-alone package or does it have to open and build in PackageMaker each time we distribute it? Maybe a .dmg would be better to then tell the user the correct place to move the files?
