    I upgraded from the 24' iMac and noticed that the new one is soooooo much louder than the old iMac, the 24' is almost silent but this new one the fan is veryvery noticeable. the body is also really hot. Is this normal?

    Depends on what you're doing. The 27" I use is really quiet, even more so than my MacBook.

    Download iStat Nano (widget) from Apple and tell us your temps and also your fan speeds. The new iMacs should be pretty silent, even when hot.

    It will be pretty warm, the aluminum carries the heat very well. I'd download iStat to check your temps, processes, etc and see if there is anything out of the ordinary.

    on my macbook air the dock process is so little that it doesn't even make it into the list...

    Try restarting the dock, or deleting the .plist for it, that may help. Looks like you just encountered a glitch which is conveniently sucking up all of your CPU.

    restarting the dock doesn't help, it automatically goes back to 400%, how do i delete the .plist?

    Hi Zteven,
    go to:

    Hard Drive/Users/{your name}/Library/Preferences/com.apple.dock.plist

    I'll be created new again.

    Also worth asking is: do you have any 3rd party addons that affect the way your dock works?

    Are you using Parallels 6 and just upgraded to OS X 10.6.8?

    "ISSUE
    After updating the Mac OS X to version 10.6.8, with Parallels Desktop 6 for Mac installed, the Mac system’s Dock process may start consuming 100% of the CPU core. This results in slower than expected Mac OS operations."
