Installer-dev mailing list (Installer-dev@lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/installer-dev/site_archiver%40lists.a... I am creating a product installer metapackage, using the wonderful Iceberg. The product runs on 10.2 and above. However, some components are different in Tiger and in Panther/Jaguar. Also, some other components are different between Intel and PPC Macs. I am using separate packages for these different components, and I'm trying to use the installer to decide which components are right for each possible Mac. All of the components have the Selected attribute set. None of them have the "Required" flag set. Iceberg allows the creation of requirements, which are supported in 10.4 and 10.3, and ignored in 10.2. According to documentation, in 10.3 and 10.4 if requirements are found, the InstallationCheck script is ignored. So what I've done is to create both requirements and InstallationCheck scripts for each component. If I install my product on 10.4 (which uses the requirements and ignores the script), everything seems to work perfectly. If I look at the components during the Install by pressing the Customize button, I can see that the components that do not match the requirements are greyed out. If I run my installer on a 10.3 system, the error message that is associated with my first 10.4-only component is displayed, and the user's only option is to close the installer. If I run my installer on a 10.2 system, a screen immediately appears that says the software cannot be installed on this computer. Is it possible to achieve the same results that I see on my 10.4 system while installing on earlier versions of OS X? What value are you returning in the InstallationCheck script when it shall be greyed out? Your description looks to match the "How can I install different versions of an application depending on the Mac OS X version?" case of the document available here: http://s.sudre.free.fr/Software/documentation/Iceberg/English.lproj/ documentation/FAQ.html This email sent to site_archiver@lists.apple.com
