    I own one of the first generation unibody macbooks (not pro). When in idle my CPU is running at ~1550Mhz. I was wondering if this behavior is normal? I was always under the impression that this particular CPU (Core 2 Duo) would be able to go as low as 800Mhz? I am using Lion.

    Mac like to keep there image, so they go halfway. They make it energy efficient by putting the MHz down, but will respond slightly quicker when suddenly a task is thrown at its face. Also, there may be some random processing going on (often with printer drivers) Check activity monitor for rogue processes.
