Generally speaking, program updates are important (many updates fix security problems), and while we attempt to automate as many updates as possible, some updates cannot be applied without an administrator’s password. When this situation arises, please send e-mail to helpdesk@math.purdue.edu and we will be happy to help you finish the install process.
Additionally, the many common applications available by opening Finder, selecting [Macintosh HD] and then selecting [Math Applications], are regularly updated by the Math Computer Systems staff.
