Does anyone know of a way to prevent users on a computer from seeing the Yosemite update? I've got three machines here now that users (that are required to be admins) have "accidentally" upgraded to 10.10 and now I have to handle them differently as a result. (for now please set aside the "but why don't you want them to update?" question, that's a different topic for a different thread)


I work for the Department of Redundancy Department
