I'm having an issue trying to get Yosemite upgrade pushed out to students with locked down computers.
For 10.8 and 10.9 we had it set up to where they'd run a policy putting the installer.app in their applications, and then run a script targeting this the "Install OS X Whatever" executable file to run like so:
/Applications/Install OS X Mountain Lion.app/Contents/MacOS/Install OS X Mountain Lion&
But with 10.10 in the Contents/MacOS/ folder all there is is the InstallAssistant executable. Is there any way to get this to work?
