The "Installer Javascript Reference" documentation is not providing some useful information when it comes to OS version checks. (1) To check the OS version, you need to compare your minimum, maximum version number against system.version.ProductVersion or my.target.systemVersion.ProductVersion. The documentation only talks about the ProductVersion key for system.version and it only vaguely points to the man page of sw_vers. (Bug ID#6286814) (2) If you check the system version from a volume-check script for from a choice, you definitely need to be aware that if no OS is installed on a partition, an exception is raised if you use: A solution I found is to check that my.target.systemVersion is not undefined (this is a Javascript constant) before trying to compare an OS version. As a matter of fact this allows you to check whether a Mac OS X distribution is installed or not on a partition. As was said in previous posts, PackageMaker 3 generates buggy OS version requirements because it does not use the compareVersions method. But it apparently uses a trick to deal with this raised exception. Now, what happens if this exception is raised in your volume-check script and you do not deal with it? 1. The partitions with no OS can't be selected (that's OK in most cases). 2. Installer.app displays incorrect inversion regarding the volume- check processing status: This email sent to site_archiver@lists.apple.com
