I have a MacBook, using iMac atm but my MacBook is running 50-60% system, 0.5-1.5 user, and i do not know why its using so much of my CPU... No programs are running except Activity Monitor... So I'm not sure whats going on, i have all the latest Airport, firmware and all that...

Any help? Many thanks :]

I have iStat on my iMac, but not on the MacBook.

I just reset the computer so it will take 5 minutes to reboot... another symptom of the CPU usage =\ I'll have the processes soon.

And Activity Monitor is basically iStat, it is what iStat uses to get the information... but the thing is there is no reason why it should be using this much of the CPU...

None, they're all using 400-600kb and 2mb tops for Air port... nothing huge, this is why I'm confused

Oh i do have WindowServer running at 19.12 Real Memory still not much but biggest process...

Check to see if any of the *Sync clients are running. If you're using Mobile Me and syncing automatically, they can chew up huge amount of CPU cycles. If so, once they're idle check again. I'll jump from an average 5-7% to 31% System usage and more in a heartbeat with a sync cycle.

Don't use Mobile Me, this computer has basically nothing on it after a reinstall.
