I will preface this, with the truth that I know little about Macs :-)
I am trying to workout a way to block application installations (or executions) on Macs. We have a subset of executive users (meaning they "need" root on the box) who have Macs. However, the are installing applications like Skpe, that break our Corporate Policies. Does anyone know of a software to manage this? Preferably Open Source.
