- Why is it necessary to ground the macs at all? On my computer, the cables
- to both the monitor and the computer connect to the computer by TWO (count
- them ...TWO) pins/sockets. The ground is a safeguard so that a device will
- blow a fuse if a short circuit occurs in the CASE or similar (it will also
- blow a fuse if the motherboard short circuits, but not thru ground). If the
- computer is not using this as a ground (and has a plastic case anyway), why
- is it so necesssary to ground it externally?
