An installation package that checks for a certain previous version of an application, then installs the changed files/directories, is an effectively an updater and is certainly possible with PackageMaker. If you mean something that actually patches files ala diff/patch, then, no, you can't do that easily with PackageMaker (you _could_ with a postflight script, but that's really violating the spirit of install packages) I am using PackageMaker tocreate installers for my application. It seems, however that with PackageMaker it is not possible to create updaters. How can I create an udater to an application installed by the installer created by PackageMaker?
