    Hi.
    I'm scratching my head since i saw itunes consuming 12% of cpu when doing nothing!
    iTunes in my imac and mb keeps at 0%, why the hell this doesn't happen in the powerbook?

    Version 8 in the three macs.

    Any suggestions?

    It's very normal; iTunes is processor intensive for the older PPC processors and less for the Intel simply because the Intel processors are more efficient and are faster.

    Exactly. I use iTunes on a PBG4 667 and without the 1GB of RAM my system would be killed by iTunes.

    Well, that came through my mind also, but something isn't right. Let's see. For much efficiency that intel chips have, 12% usage in ppc, could be like 3 or 4% on intel. And that's not right. With the open .app (without playing) and hidden, activity monitor reports between 0 and 0,3% cpu on intel which cannot translate to 11 to 13% in a 1.5Ghz ppc. An open app with no activity and no background processes shouldn't use any cpu. Isn't this true??
    And more; now iTunes is playing and using 9%; less than when not playing!!!
