4th Dimension "key disk" system changed to accommodate new Macs

Another example of an issue noted here before (such as a and b):

Steve Reubart notes that the "key disk" system used by ACI US to add user licenses to a 4th Dimension server was recently changed because floppy drives are no longer standard equipment on new Macs. If you are planning to move your 4D server to a system without a floppy drive, you will need to contact ACI US to obtain new access numbers. There is a $25 fee for this service, as confirmed by ACI US tech support.
