My installer needs to run on 10.2, 10.3, and 10.4. When my installer is run on 10.2, I need to install a second package. I have the second package (mpkg file) from a third party. I don't have the components of the second package. How do I build my installer so the third-party installer will only be executed on 10.2? In their Stuff .mpkg, you need to add an (or modify the) InstallationCheck script so that it returns 64 if the OS is not 10.2. To find how to write such a script, you can have a look at the InstallationScript in some Apple Packages for instance. This email sent to site_archiver@lists.apple.com
