Hi I have recently moved to Mountain Lion and am surprised to find this quirk. When I purchase an APP on the APP Store, it asks for the system administrator Id and password (ok for admin reasons), then it asks for the icloud account (ok to pay). Point is I should not be able to start the APP Store if the administrator does not agree to me installing anything. Sort of part of the "parental controls" section. But the way it is done now is sort of last minute "ooops we forgot to tell you that the Admin has to agree". I would have thought that this quirk was fixed in Mountain Lion.
