Mac OS X 10.6.8 and dock process high CPU

Greetings:

I have updated today my Mac OS X to 10.6.8 on my MacBook Pro 15".

After the update and reboot, the computer now runs the "Dock" process all the time at 90 to 95% CPU User is steady at 57% even with only the finder open. After few minutes, the fan spins at 4000 to 5000 rpm and more if I open other applications.

I have done this as per suggestion from other users in the forum:

1. Boot in safe-mode.

2. Repair permissions.

3. Boot and install the combo update 10.6.8

4. Reboot

5. Repair permissions again.

No luck at all. A colleague in the office has updated his MacBook Air and has no issues at all.

Just in note: I installed the 10.6.8 as usual from the Apple Software Update.

Best regards

Claudio

If you run Parallels, it's probably this issue:

Hello Claudio:

I saw one other post like yours. I do not have similar hardware, so I have no comparison.

You might try (in addition to what you have already done) trashing a preference file (com.apple.dock.plist) and restarting. That will reset your dock to default values.

If that does not help, try resetting the PRAM and SMC.

Barry

P.S. I seriously doubt permissions have anything to do with your problem.

I'll add my thanks to captfred.

I just installed 10.6.8 and ran into the same issue. I checked in the dock process and saw a reference to Parallels and began to look for an answer. Yours is dead-on. I hope Parallels fixes it soon as I've come to like having that Stack there for me to select the Windows application I need at the time and have it start Parallels for me.

Thanks again,
