    Mac Pro PSU buzz
    Hi all! My power supply has been making this awful buzz (not the HDs or fan) and I called apple support and they said to take it to the nearby applecare center run by scotsys... so I took it there and they said they replaced the psu and it is now working fine

    I plugged it in and turned it on.. what do I hear? The same buzz but louder!!! My MacBook also has a kernel panic when I connect it to my Mac Pro with ethernet now

    Any suggestions?

    Thanks! :mac:

    Well, it sounds like another trip to the Applecare center is in order, and test the fix on site before taking it home after they "fix" it again, to be sure they really have!

    plug it in before you take it home.
