    When I wake my Mac Pro it makes a click sound, is this normal?
    It's the Mac in my signature. I've always wondered if this may not be something wrong, I've bought it refurbished from a seller a few weeks ago.

    Probably the sound of the HDD waking up. In my experience WD drives are noisier than other drives and make clicking sounds. It OK, nothing to worry about.

    It is most likely to be the relay inside the power supply - it clicks when you turn the machine on or off and is normal.

    +1 on the PSU relay. Happens in both my Mac Pros and in my old G5.
