I have an IT manager that will not allow our macs running OS 10.3.3 on the network because he is concerned about security issues. He does not feel the mac will be secure or live well in a PC Banking environment. I have tried to explain to him that they are enately more secure than Windows machines but he is not listening. Is there any evidence that I can steer him to that will support my point and help him see that his worries are invalid. We have over 500 PC's here and 10 Macs all the macs are running Virex.
