Hello Apple people! First off, let me apologize in advance because this may be the wrong forum to post this on. If anyone does know of a forum that is better suited for this question, I would appreciate being pointed in the right direction! My issue is this: I have a closed security network of about 50 Windows 7 PCs regulated by a Windows Server. The network is designed for security and the environment is such that there is no internet access, and the computers all have disabled USB ports. I've just added our first Macintosh to our network (a brand new Mac Mini). This is the first time Ive used the OSX and have been very impressed with the overall design and usability of the device. The problem I'm having though is one of security. Using different user accounts, I've managed to disable the Wifi, BlueTooth, and FireWire ports. However I've been unable to disable the USB ports for data devices. On a Windows PC, this is relatively simply due to the fact that you can completely block out the USB ports in the BIOS, and then use PS2 Mouse and Keyboard on the system. The Mac doesn't have a PS2 port though, so I'm not sure how to go about this! If anyone has any ideas, I'd be greatful to hear them. Thanks in advance.
