On some Macs I'm seeing the following in the JAMF Pro logs:
Copying Apple iTunes v12.7.0.166.pkg...
Installing Apple iTunes v12.7.0.166.pkg...
Installation failed. The installer reported: installer: Error - This software is not supported on your system.
Cause: It turns out that iTunes 12.7 checks not only the minimum operating system version (10.10.5), but also the minimum build (14F2511):
From iTunes12.7.pkg/Distribution:
[...]
function InstallationCheck(prefix) {
if (system.compareVersions(system.version.ProductVersion, '10.10.5') < 0) {
my.result.message = system.localizedStringWithFormat('ERROR_B85E600482', '10.10.5');
my.result.type = 'Fatal';
return false;
}
if (compareBuildVersions(system.version.ProductBuildVersion, '14F2511') < 0) {
my.result.message = system.localizedString('ERROR_3491501876');
my.result.type = 'Fatal';
return false;
}
my.result.message = system.localizedString('ERROR_3491501876');
if (!dontDowngrade("/")) {
my.result.type = 'Fatal';
return false;
}
return true;
}
[...]
This is new behavior as of iTunes 12.7. iTunes v12.6.2, and earlier, only checks the operating system, but not the build.
Solutions:
1. For Macs still running 10.10.5, create a Smart Group of Macs with build 14F2511, and restrict your iTunes 12.7 policy to those Macs;
2. Upgrade your Macs from 10.10.5, especially since Apple no longer provides security fixes for Yosemite.
