    Anyone else get this problem? When I get the USB port attached to a device, I hear pops until the cable is snugged in. I've never seen a computer do this for the past 10 years.

    The Mac Pro is connected directly to a wall outlet via 3 prong.

    No surge protector?

    I had one, but it burnt out. So I am using it directly now.

    The same happened even with the surge protector.

    Worth to take it down to an Apple store?

    I have heard this before. Somehow something is touching and sending a signal to the speakers. I don't know exactly how. I wouldn't worry about it much though.

    It's kind of annoying. The line out from the Mac Pro goes to a professional Mackie mixer, then from the mixer it goes out to a professional set of speakers via grounded 1'4" connection.

    Also there are random pops throughout the whole day. Not worth taking to the Mac store?

    Thanks

    Thanks dude.
    I think something's wrong with the sound card (onboard, whatever it is) because the pops are there under OSX as well. Also the PSU is making buzzing noises randomy under Windows.

    I hope the turnaround time is very short. I will try to take it to them this saturday because I'm fairly busy this week and need the machine
