    Hello
    I have white macbook c2duo 2GHz.
    After last iTunes update it still consumes about 60% of CPU whe running. If I say running i mean that it's not playing any music. Library Sharing is off. I was trying to find out something but i had no luck. Only I can say is that the same thing is occuring on my friend "Old" Macbook Pro (intel c2duo) but not on any iMac or Unibody Macbook i have seen.
    If anyone can help i will be pleased.
    Thanks

    Not happening on my MacBook with iTunes 10.0.1 (22).

    Code:
    Hardware Overview:
    
      Model Name:	MacBook
      Model Identifier:	MacBook3,1
      Processor Name:	Intel Core 2 Duo
      Processor Speed:	2 GHz
      Number Of Processors:	1
      Total Number Of Cores:	2
      L2 Cache:	4 MB
      Memory:	4 GB
    
    Do you have any iTunes plugins installed? You could open Activity Monitor (in Utilities), select the iTunes process and then Sample Process. This might indicate what iTunes is doing that requires so much cpu power.

    Solved

    Thanks...
    After inspect the stack, it looks like that something was forcing GUI to redraw again and again.

    At first i reinstall iTunes and it helps much. But still about 30% CPU.

    To my surprice that problem was solved only by sing out and back in iTunesStore....

    May be this can help someone with the same problem..
