Has anyone seeing this issue?
I have a PreStage that relies on the serial number to automatically start the image, that is currently working for other desktops (Mac Mini, iMac and older MacPros), but when using a MacPro6,1 and the serial number starts with an F, it does not work. If I use for the same MacPro6,1 the MAC address or the network segments it works. Unfortunately, I cannot use these for our company requirements, so I am stuck in using the serial number.
