2011 27" i5 Imac CPU sits at 25% when idle?

[iloveimac]

Hi

I have not long had my Imac annd i have noticed that after boot, with no apps what so ever running the CPU is still showing (via istatpro) CPU usage at 25%

Erm, well this obviously isn't right, but I don't know what to do?

Any help would be greatly appreciated

Have a look at Activity Monitor (Applications / Utilities /) and select All Processes and sort by CPU to see what the culprit may be.

The Dock process includes the Dashboard, maybe take some widgets of the Dashboard to see, which may be the culprit.

Please have a look at the screenshot attached

It's probably coming from your vm dock folder. What happened is 10.6.8 update somehow screwed up parallels vm dock folder to utilized 100% of the CPU. You will have to disable it in your vm settings.

Here's the link for the instructions.
